Do batteries save money without solar?

Which battery is right for me?

There are an array of choices available which include Tesla Powerwall, SolarEdge, Huawei Luna, MyEnergi Libbi and GivEnergy. As experts in battery installations, Carter Renewables will identify the best options for the specific need considering items such as capacity, cost, efficiency and life expectancy.

These sleek and efficient Tesla Powerwalls offer a range of benefits that make them an attractive addition to your property.

So how can I save money without solar panels?

In areas where utilities charge different rates for electricity at different times of the day (TOU tariffs), battery storage systems can store energy during off-peak hours when electricity is cheaper and then use it during peak hours when electricity rates are higher. This load shifting can significantly reduce electricity bills. Read more about TOU tariffs from the Energy Saving Trust.

For commercial and industrial customers, a significant portion of the electricity bill can come from demand charges, which are fees based on the highest rate of electricity usage during a billing period. Battery storage systems can help reduce these demand charges by discharging stored energy during periods of high demand, thus lowering the peak usage.

While not directly a money-saving feature, having a battery storage system can provide backup power during outages, which can be invaluable for avoiding productivity losses or spoilage in businesses, and discomfort or disruptions in residential settings. Have peace of mind that in these situations, your battery storage system has got your back! This happened recently at Carter Renewables HQ, where our trusty Tesla Powerwall stepped up to the fore after a power cut (below).

Various regions offer incentives and rebates for installing battery storage systems, which can offset the initial cost and make the investment more attractive. In December 2023, the UK government introduced VAT relief on the installation of battery storage systems.

What else do I have to consider before installation?

While battery storage systems without solar panels can save money in the long run, the savings depend on the specific circumstances, including local electricity rates, any differences between peak and off-peak rates, the initial cost of the technology and installation, as well as ongoing maintenance, and individual usage patterns.

Solar Garden Lights in garden

Solar Garden Lights – are they worth it?

Solar garden lights have become increasingly popular in recent years.
  1. Environmentally Friendly: Solar lights utilise solar energy, a renewable and abundant resource, reducing reliance on fossil fuels. By generating power from the sun, solar lights help decrease greenhouse gas emissions and pollution.
  2. Cost-Effective: Solar lights operate independently of the power grid, eliminating electricity bills associated with outdoor lighting. Once installed, solar lights require minimal maintenance, saving time and money in the long run.
  3. Easy Installation: Solar lights are wireless, making installation simple and safe without the need for electrical expertise. They can be installed in various locations, without concern for proximity to power outlets.
  4. Safety: Solar lights typically operate at low voltage, reducing the risk of electrical hazards. Most solar lights come with sensors that automatically turn the lights on at dusk and off at dawn, enhancing convenience and security.
  5. Aesthetic Appeal: Available in numerous styles, colours, and shapes, solar lights can enhance the aesthetic appeal of gardens and outdoor spaces.
  6. Recyclable parts: Garden solar lights are made up of solar panels, batteries, LED lights, and plastic casings, all of which can be separated and recycled appropriately. Recycling these components allows for the recovery of valuable materials and reduces the environmental impact of electronic waste, and some suppliers even offer their own recycling programs. If you’re local to Reading, check out re3, where you can check the recyclability of almost every household item, including garden solar lights!
Use the re3 website (above) to check what you can recycle from around your house.
  1. Dependence on Sunlight: Solar lights depend on sunlight to charge, which can be inconsistent due to weather conditions, geographic location, and seasonal changes.In addition to this, shorter daylight hours and overcast skies during winter can significantly reduce the performance of solar lights.
  2. Initial Cost: Although costs have decreased, the initial purchase price of quality solar garden lights can be higher compared to traditional lighting options.
  3. Light Intensity: Solar lights generally produce less intense light compared to wired electric lights, which may not be suitable for areas requiring strong illumination.
  4. Battery Lifespan: The rechargeable batteries in solar lights typically last 1-2 years before needing replacement, which incurs additional costs and maintenance.
  5. Durability Issues: Prolonged exposure to harsh weather conditions can damage solar lights, affecting their longevity and performance. There is also a wide range of product quality on the market, and lower-quality solar lights may fail prematurely or underperform.
  6. Recycling Difficulties: Although individual components of solar lighting can be recycled, this can be a time-costly exercise by the customer, as very few recycling centres recycle the lights as a whole unit. Putting unwanted or broken solar lights into general waste collections, or disposing via incineration is extremely harmful to the environment, due to the hazardous materials solar lights contain, such as batteries and bulbs.

Smart Tariffs for Dummies

Smart Tariffs for Dummies

Smart tariffs, also known as time-of-use (TOU) tariffs or dynamic pricing, are electricity pricing structures that vary based on the time of day, day of the week, or other predetermined factors. These tariffs aim to reflect the actual cost of generating electricity at different times and encourage consumers to shift their electricity usage to off-peak periods when energy costs are lower.

Smart tariffs typically involve higher prices during peak demand periods, such as in the evening when people return home from work and energy consumption spikes, and lower prices during times of lower demand, such as late at night or early morning.

By offering incentives for consumers to use electricity during off-peak hours, smart tariffs can help utilities manage demand more efficiently, reduce strain on the grid, and promote the integration of renewable energy sources. Additionally, they can empower consumers to make more informed decisions about their energy usage and potentially lower their electricity bills by adjusting their consumption patterns accordingly.

Market leader and the UK’s most awarded energy supplier Octopus Energy have a wide range of tariffs, all suited to customers’ differing needs and lifestyles, but choosing the tariff for you can be a minefield! Here we break down the tariffs and explain in layman’s terms which is the tariff for you and your household.

smart tariff

Agile Octopus

With Agile Octopus, customers get access to half-hourly energy prices, tied to wholesale prices and updated daily. So when wholesale electricity prices drop, so do your bills – and if you can shift your daily electricity use outside of peak times, typically between 4-7pm, you can save even more. Agile prices can spike up to 100 p/kWh any time – although a in Winter 2023-24 the max 30 min slot was 68p/kWh with the cheapest being -4p/kWh! Yes they actually paid you to use electricity. This tariff is therefore best suited to customers who can shift large amounts of their energy use to avoid these expensive peaks, often by using smart home technologies like solar and batteries.

Intelligent Octopus Go

If you own an electric vehicle (EV), then Intelligent Octopus Go is the tariff for you! Automatically charge your car when it’s cheapest and get super-low smart charging rates plus six hours of cheap energy for your whole home every night. Making the most out of this tariff is as simple as connecting your EV or charger in the Octopus app, before just plugging in your car and telling Octopus how much charge you need. Octopus will then automatically schedule your charge for when energy is cheapest and greenest, and you’ll only pay 7.5p/kWh regardless of the time of day.

Octopus Flux

For you solar PV and battery owners out there, the Octopus Flux tariff has been designed exclusively for your needs. Compatible with all solar PV and battery systems, Octopus Flux is an import and export tariff optimised to give you the best rates for consuming and selling your energy and support the grid during peak periods. It gives customers super-cheap rates between 02:00 – 05:00 every day, when you can top up your battery with any extra energy you may need, as well as a peak rate between 16:00 – 19:00, the optimum time to discharge your battery and export surplus energy back to the grid.

Octopus Flux tariff

Cosy Octopus

Finally, if you’re the proud owner of a heat pump, check out the Cosy Octopus tariff to keep your home warm for less with super cheap rates, twice a day, every day. It’s a three-rate tariff with double dip Cosy Hours every day: six hours of super-cheap electric to warm your home. You need a heat pump to be eligible for Cosy Octopus, but it doesn’t need to have been installed by Octopus Energy. If you’re in the process of getting one installed, you can still switch to Cosy.

Cosy Octopus tariff

Picking the right tariff depends on the low-carbon technologies you own (i.e. EVs, heat pumps, solar or battery storage) and your personal energy consumption. Octopus Energy have a wide range of tariffs, so if you’re looking for something different than the ones mentioned above, check out their full range or take their quick quiz. Even if you’re at the very start of your renewable journey, and don’t have any smart technologies (yet!), you can save cash and carbon by shifting your consumption to cheaper times. Octopus Tracker is a great introduction to smarter energy, with different energy prices daily.

Solar Power Diverters

Solar Power Diverters 101

You’ve installed solar PV panels and you’re generating renewable energy from the sun, so what’s next?  What about a solar diverter, a handy device that works alongside your solar panels to enhance energy utilisation within your household.

A solar diverter’s function is to channel surplus electricity produced by the solar panels towards a designated appliance, typically for water heating, rather than exporting it to the grid, enhancing the overall efficiency of the solar panels for the homeowner.

When the solar panels produce an excess of electricity beyond the current household consumption, the solar diverter automatically detects this surplus and redirects the extra energy to a specified appliance, such as water heaters, or electric heating systems. Most electric vehicle (EV) chargers can also do this too. This increases the self-consumption of solar energy, reducing reliance on grid power and thus, lowering electricity bills. Although using a diverter to heat water is the most common use, it’s worth noting that solar diverters can’t be used to heat hot water if a combi boiler is installed in your home.

Ultimately, the price of a solar diverter is influenced by various factors such as the brand, model, features, and installation specifications. The good news is, they qualify for 0% VAT, which helps improve the payback by saving typical gas use to heat the water. However, the optimal utilisation of solar energy varies depending on individual circumstances. For most users, maximising savings and achieving quicker payback involves using surplus electricity within the home. Yet, if you benefit from a favourable solar buy-back tariff, selling your excess energy back to the grid may prove more worthwhile.

Today we shine a spotlight on the myenergi eddi. As myenergi explain themselves, “a solar photovoltaic (PV) system without an eddi is like a car without a steering wheel or driver. Without an eddi, you have no control over where you want your self-generated energy to go, or how you want to use it.

By installing a myenergi eddi, you are able to make the most of the green energy generated from your solar PV or even your wind generation system. By directing the excess renewable energy to other appliances, you can, for example, heat 100% of your hot water on self-generated green energy.

eddi uses state-of-the-art technology to monitor PV performance and your energy consumption. This means that surplus power can always be used in the best way – heating your water with solar ready for when you need it most. The eddi can fully heat your water using much lower amounts of solar generation, such as during winter mornings, late summer evenings or when it’s overcast, ultimately improving the life and efficiency of the heat pump, and prevents reliance on top ups from the grid.

At Carter Renewables, we highly recommend consulting with us to obtain an accurate cost estimate for a solar diverter tailored to your home, lifestyle and specific requirements. Contact us today to get your solar diverter journey started, and to get that metaphoric steering wheel added to your car!

Electrical Safety at Home – Don’t Be Shocked

Our Planet Earth has existed for approximately 4.5 billion years, and we have only enjoyed domestic electricity for about 150 of them. Electricity is now something we absolutely take for granted: to light and heat our homes, cook our food, charge the devices to entertain us and much more. On the rare occasion of a power outage, we spring to our pre-charged smartphones to enquire about the cause, and more often than not are able to utilise stored electricity in some form until usual service resumes.

Yet, due to its convenience and normality within our modern lives, we tend to forget that electricity has the power to kill humans when manhandled, and around 2.5 million Brits receive an electric shock annually. That’s a shocking (!) 4% of the population falling foul each year to everything from electrical fires to fatal incidents, often sadly because of faults around their house.

Today we will explore the most common current (ok I’ll stop now) reasons for an electrical mishap, and how you can safeguard yourself against them.

It’s the main culprit for sure – old or faulty wiring will lead to electrical fires or immediate shocks. Even if you’re not a sparky, you can still learn to distinguish between old and new wiring from the colouring. Old plug wiring consists of a red live wire, black neutral wire and a green/yellow or a pure green protective earth (PE) wire:

Old Plug Wiring Colours
Know your old from your new!

Plugs with modern wiring contain a brown wire that is live, a blue neutral wire and a green/yellow PE wire. Broadly speaking, the wiring connections in new plugs are the same as in old ones but with different colours for the neutral and live wires.

As well as this, if you have any of the following in your house, get in touch with us today for us to check them out safely:

  • Cables coated in black rubber were phased out in the 60s
  • Cables coated in lead or fabric were installed pre-60s
  • A wooden-backed fuse box or cast iron switches would be pre-60s
  • Wall-mounted light switches in the bathroom are pre-60s

If the back of your TV, or by your bedside table looks like the image below on a permanent basis, please reconsider installing some additional sockets to cope with your electrical appliance demand. Misuse of extension plugs and leads is one of the biggest electrical offenders in the UK, not helped by the fact that appliances are often plugged into them constantly throughout the day and night, silently overheating, resulting in melted sockets or worse case scenario, house fires.

Overloaded Extension Sockets
Dangerously overloaded extension sockets

If you do have a lot of devices, think about only plugging them in when you need to use them, as the purpose of extension leads was originally for that exact use only – such as when you needed additional electricity to mow the lawn or vacuum your car. Additionally, make sure the extension lead you’re using is up to the job – the capacity should well exceed the electrical demand you’re placing on the cord.

We literally can’t live without them, needing a charger for everything from our phone, laptop and kids’ tablets to our vacuum cleaners and toothbrushes! And while the original charger that came with your device may be compliant with UK properties and our electrical systems, there’s a high chance that any replacement or ‘spare’ chargers, bought in a rush from Amazon Prime, are low-quality products made in China for as little as 3p a pop.

So how can you check your charger is compliant with UK properties and your plug sockets, in order to keep safe?

  • Check the Plug Pin: Examine the pins and ensure there is a minimum distance of 9.5mm between the edge of the pins and the charger’s edge. Failure to meet this standard could pose a risk of electric shock. Difficulty in plugging the charger into the socket may indicate incorrect pin length or size.
  • Verify the Markings: When purchasing a charger, ensure the brand’s markings are clearly visible. The output voltage should match that of your device, and a CE mark should be present to confirm compliance with EU regulations.
  • Refer to the Manual: Upon purchasing a device or charger, refer to the provided instructions for proper usage guidelines. These instructions will include details on correctly using the charger and offer essential electrical guidance.

Step Inside the Carter ‘Green’ House

Being in the trade, I have the benefit of being able to install at below-market rates, which was a huge benefit and incentive to get started on this project. My main intentions, however, were to demonstrate how using renewables together can a) reduce your carbon footprint,  b) save you money, and c) earn you money.

The house is a 1970 bungalow, with approximately 145m2 of floor area, insulated cavity walls (although I do wonder sometimes!), old wood-framed double glazed windows, and a rather old gas boiler. The radiators throughout the house were a mix of single and double panels, which I planned to upgrade. Fortunately, the house, being an L-shape, had two zones for the heating plumbed in and 15mm legs to the radiators would help the flow rates for future heat pump installation

So far, I have added 7.91kWp of solar PV across the east, south and west elevations of the house to maximise solar efficiency, converting sunlight into renewable energy to power various electrical devices. Around the same time, I installed a 13.5kWh battery capable of charging and discharging energy from the grid, and storing excess solar energy to utilise during periods of high demand on the grid, or overnight. A 12kW heat pump combined with a smart Domestic Hot Water (DHW) cylinder is a more environmentally-friendly heating option compared to traditional boilers, and powered by the solar PV panels, reduces not only my carbon footprint, but my energy bills too. And of course, an EV charger was one of the first things to be installed to help power the Carter Electrical fleet!

Solar PV Panels
Solar PV panels across three of the elevations of the bungalow

As a snapshot, in 2022 we used 17,673 kWh of gas at an average cost of 6p/kWh, mainly for heating and domestic hot water, but also a small bit for cooking, bringing our net cost of gas for the year to £1,034. In addition to this, we imported 5182 kWh of electricity costing £571 – a small part was for electric vehicle (EV) charging, but the bulk was for domestic use. This meant we had a total demand of 22,855 kWh from the grid,.

Our gas usage in 2023 was 0 kWh! This was largely down to installing the heat pump and induction hob, and removing the gas to the property. If we had remained on gas with the existing boiler, the costs would have nearly doubled. Our electricity usage was 10,900 kWh, of which 7313 kWh came from the grid at an average cost of 13p/kWh. Therefore, grid electricity cost £928.64 however, I exported 1723 kWh worth £361.87 at an average of 21p/kWh. In addition to this, there were some Octopus Energy Octoplus saving credits and seven referrals which totalled £405.36. So once export was taken away from usage, my net cost of electricity was £161.41 for the year. This meant an incredible saving of over £1440 compared to 2022; our combined savings on gas and electricity was closer to over £2500.

7kWp of solar PV with a Tesla Powerwall battery was approximately £20,000. You can get cheaper, but this system is high-specification, using SolarEdge optimisers to minimise tree shading and multiple elevations as in the case of our bungalow. It is a large battery, but this allows us to maximise charging with cheap off-peak electricity in the winter, as well as capturing all the generation in the summer. The Octopus Agile Tariff and the battery has made the unit cost of electricity extremely low.

Tesla Powerwall
Jon’s Tesla Powerwall, which is high-specification, cost £20,000

The 12kW Samsung HTQ heat pump, Mixergy Cylinder and Homely controls came to about £12,500, although there is a £7,500 Boiler Upgrade Scheme grant available which brings the cost down closer to a boiler change. On top of that, our new radiators cost between £200-£300 per unit to swap. 

Samsung HTQ Heat Pump

It is a large initial outlay, but we are effectively buying 25 years of electricity upfront with the solar panels, and the battery then facilitates the ability to maximise the generation use and access to off peak cheaper electricity. With the cheaper electricity and the 350-500% efficiency of the heat pump, the cost to heat the house and domestic hot water drops dramatically and will only get cheaper. Remember – the price of gas will only ever go up due to it being a finite resource! 

Heat Pump Efficiency
Jon’s heat pump running yesterday at over 500% efficiency

It’s a change of mindset: we buy a car, a fridge or a sofa out of necessity and it’s not always the cheapest. We need electricity to run the house and we need to heat the house in winter and hot water all the time, so why not invest in something that allows you to do it cheaper and also helps reduce the use of fossil fuels at the same time?

I want to look to improve the efficiency of the heat pump, which is a lot of fun through experimentation and playing with settings to best suit our climate. I installed data collectors on all new equipment, so I’m constantly monitoring it to see if there are improvements that can be made. Next on the list, is to improve the insulation of the house and minimise draughts – I have a lot of old, leaky double-glazed windows that could be improved! Tech-wise, I’d love a wind turbine, but it’s not feasible (or so I’m told by my wife).

Do heat pumps work? Yes. Do solar panels work? Yes. Do battery storage systems work? YES. Together they are a large initial investment, however, if you have the capital expenditure, then it is clear and obvious you can reduce the operational expenditure of your house quite significantly. I reduced my utility costs by 90% in my first year of making these changes, and I am looking forward to continuing to analyse my energy usage in 2024 to further enjoy the long-term financial benefits, as well as knowing I’m reducing mine and my family’s carbon footprint!

Energy Efficiency Tips for Businesses: Reducing Carbon Footprint with Renewables

In an era where environmental consciousness is no longer an option but a necessity, businesses are increasingly recognising the importance of reducing their carbon footprint and embracing sustainable practices. Energy efficiency plays a pivotal role in this journey, and one of the most impactful ways to achieve it is by incorporating renewable energy sources. In our first blog of 2024, we’ll explore a few practical and achievable energy efficiency tips for businesses committed to minimising their environmental impact and making a positive contribution to the planet.

This should be on your to-do list for early in the year! Before embarking on any energy efficiency initiative, businesses should start with a thorough energy audit. This process involves assessing current energy consumption patterns and identifying areas where improvements could be made. The insights gained from an energy audit provide a roadmap for implementing targeted efficiency measures, as well as some short and long-term SMART goals for you to tick off throughout the year.

Investing in renewable energy sources is a cornerstone of any sustainable business strategy. Solar power is increasingly accessible and offers a clean, renewable alternative to traditional energy sources. Installing solar panels on rooftops allows for on-site energy generation, reducing reliance on the grid. Excess solar energy can be stored in Tesla Powerwalls, and could reduce your electricity bill by up to 80%.

If you’re not using LED bulbs in your business yet, why not?! A simple yet effective way to enhance energy efficiency is by transitioning to energy-efficient lighting solutions. LED bulbs consume significantly less energy than traditional incandescent bulbs and have a longer lifespan, resulting in both cost savings and reduced carbon emissions. There’s no job too small for us at Carter Electrical: we can upgrade your lighting whether you have a small home office or a huge warehouse.

You don’t even have to spend any money to make your business more energy efficient – the commitment to energy efficiency extends beyond technology to the people within the organisation. Educate employees about the importance of energy conservation and encourage simple practices such as turning off lights and equipment when not in use. Engaged and informed employees can become ambassadors for sustainable practices both inside and outside the workplace.

And finally, as renewable energy sources like solar and wind are intermittent, investing in energy storage solutions such as batteries becomes crucial. These solutions enable businesses to store excess energy during peak production times and utilise it during periods of low renewable energy generation, encouraging less reliance on the grid at peak times.

Electrical safety checks and EICRs – Safeguarding your home and business

Electrical safety checks and Electrical Installation Condition Reports (EICRs) are crucial for safeguarding homes and businesses, ensuring that electrical systems are safe, compliant with regulations, and free from potential hazards. Here’s an overview of these concepts.

As a responsible homeowner, conducting regular visual inspections of your electrical systems to identify any visible issues such as damaged wiring, exposed conductors, or outdated components is a simple first step to safeguard your home, and can be done without the help of an electrician!

When using electrical appliances, ensure they are in good condition, with no frayed cords or damaged plugs, and always follow manufacturer guidelines for maintenance and replacement. Don’t forget the sockets – regularly check them and switches for signs of damage or overheating, and remember: avoid overloading sockets and use extension cords appropriately. Finally, inspect light fixtures and bulbs regularly for proper installation and any signs of wear, and replace, and dispose of, any faulty bulbs promptly.

This bit you need a sparky for!  An EICR is a detailed inspection and assessment of the fixed wiring (anything you can’t unplug) within a property. It is conducted by a qualified electrician to ensure compliance with regulations and identify potential safety issues. EICRs are typically recommended every 5 to 10 years for domestic properties and more frequently for commercial properties. They may also be required when major electrical work is carried out or when selling/buying a property.

EICRs should only be conducted by qualified and registered electricians who have the necessary competence and expertise. The inspection involves testing and assessing the condition of electrical installations, including wiring, sockets, switches, and distribution boards. After the inspection, a detailed report is provided, highlighting any issues found and recommendations for any necessary remedial work. The report will categorise issues by their severity, indicating whether immediate action is required or if it can be carried out at a later date.  Your electrician can quote for any remedial work required, to meet certification.

EICRs provide a comprehensive review of the safety of electrical installations, reducing the risk of electrical accidents, fires, and other hazards. Furthermore, they ensure compliance with safety standards and regulations.

Although some insurance policies require a valid EICR to maintain coverage, EICRs are often required when purchasing a property, to ensure the electrical systems are in good condition. Regular checks and EICRs offer peace of mind for homeowners and businesses alike, knowing that their electrical systems are safe and in good working order.

In summary, regular electrical safety checks and EICRs are essential for maintaining a safe and functional electrical system in both homes and businesses. It’s crucial to stay proactive in identifying and addressing potential issues to prevent accidents and ensure compliance with regulations. Always hire qualified professionals for inspections and electrical work, to guarantee the reliability and safety of your electrical installations.  Contact us today to book in an EICR, for your peace of mind.

Scammer or service?

“You have paid for an annual inspection and service which your installer has failed to provide…”

How many of you can relate to receiving one of these cold calls? How do they even know you have solar PV panels? How did they get your number? If anyone other than your certified solar PV installer is calling you about the panels they didn’t install, they’re probably a scam! Scammers use various methods to obtain phone numbers, and many of these methods involve exploiting information that is publicly available or accessible through various channels. Rest assured, there will never be any cold-calling or hard-sell from us, and we never pass on our customers’ personal details to third-parties.

Do I need an inspection or service on my solar PV panels?

Solar panels typically last between 25 to 30 years, although they will often still work after this time period, just producing electricity at a lower rate. The panels will often have the longest warranty in the solar PV system and the period of time that they last for is highly dependent on the manufacturer, installer and owner. Any servicing you undertake is entirely at your own discretion, and our installers can talk you through the various options at the time of installation.

Solar Panels for House

What maintenance do my solar PV panels need?

Solar PV panels are ultra low maintenance sources of renewable energy, and can add value to your home as well as saving money on energy bills. However, forget the scammers, there’s some servicing that can be carried out either by yourself or certified installers such as Carter Electrical Installation Ltd to get the most out of your panels:

  • Regular Cleaning: dirt, dust, bird droppings, and other debris can accumulate on the surface of solar panels, reducing their efficiency. Regular cleaning, typically with water and a soft brush or sponge, helps maintain peak performance. Carter Electrical Installation Ltd offers this service, along with all the safety gear so you don’t have to get up on your roof!
  • Visual Inspection: periodically inspect the solar panels for any visible damage, such as cracks or physical wear. Damaged panels may need to be replaced to maintain the overall efficiency of the system.
  • Tree Trimming: if there are nearby trees that could cast shadows on the solar panels, trimming or removing branches may be necessary to ensure maximum sunlight exposure. Tree trimming also helps to reduce the build up of leaves throughout the autumn and winter months.
  • Monitoring System Performance: many modern solar installations come with monitoring systems that allow homeowners to track the performance of their panels. Monitoring can help identify any issues with individual panels or the system as a whole.
  • Inverter Maintenance: inverters, which convert power from the panels into power for use in your home, may require occasional maintenance or replacement. Check the manufacturer’s recommendations for the specific type of inverter in your system.
  • Professional Inspections: while routine maintenance can be done by the homeowner, it’s advisable to have a professional inspection at least once a year. Professionals can identify potential issues that may not be obvious to the homeowner.
  • Warranty Compliance: adhering to the manufacturer’s guidelines and any warranty requirements is essential. Some warranties may require regular professional maintenance to remain valid.

At Carter Electrical we offer installation and complete servicing of Solar PV panels for your home or business. Additionally, we will also come out and look at your panels even if they weren’t fitted by us!

Remember, legitimate companies typically do not engage in unsolicited calls that pressure you into immediate action. If the caller is persistent, high-pressure, or unwilling to provide verifiable information, it may be a scam. Always prioritise your safety and the security of your personal information, and politely ask these cold-callers to take you off their database, and ensure you block their number.

High-efficiency solar panels are becoming more affordable and efficient, allowing homeowners to generate more electricity from a smaller area of roof space, saving hundreds of pounds a year on electricity bills. At Carter Electrical, we offer installation and servicing of Solar PV panels for your home and business. Even if they weren’t fitted by us, we’re happy to come out and look at your existing solar panels.

Solar Battery Storage

Home battery systems, like the Tesla Powerwall, store excess energy generated by solar panels for use during nighttime or power outages, increasing energy independence. Furthermore, Tesla Powerwall 2 enables people access to one of the most advanced Home Energy Storage Systems on the Market. Powerwall 2 can be retro-fitted to any existing Solar System and presents a cost-effective and industry leading Load-Shedding-Protection and Night-time Energy Storage. It can also be fitted without Solar Panels to be used as a store of power and a backup in case of mains failure.

Smart Home Energy Management

Smart thermostats, lighting, and appliances can be integrated into a home energy management system, optimising energy use and reducing utility bills. We recommend Homely, the smart controller that optimises heat pumps, to heat your home efficiently and can reduce your heating bills by 25%.

Energy-Efficient Appliances and Lighting

Upgrading to energy-efficient appliances and LED lighting can reduce electricity usage and lower utility bills. LED lighting uses up to 90% less energy than incandescent lighting and 60% less than fluorescent lighting. They also last longer – the typical lifespan of an LED bulb is up to 50,000 hours, further slashing replacement and maintenance costs.

Electric Vehicle (EV) Charging Stations

Installing EV charging stations at home can encourage the adoption of electric vehicles, which can be charged with clean, renewable energy. At Carter Electrical, we like the Myenergi Zappi EV charger, which can use energy from the national grid, solar or both.

Finally, increasing affordability, accessibility, and sustainability characterise the future of renewable energy for homeowners. As technologies advance and the transition to renewable energy accelerates, homeowners have more opportunities than ever to reduce their carbon footprint, lower energy costs, and contribute to a cleaner and more sustainable future.
