What exactly do solar panels do?

Solar panels take sunlight and turn it into electricity for your home. They use solar cells to create direct current (DC), which an inverter then changes to usable electricity (AC) for your lights, appliances, and more.

Why should I get solar panels for my home?

Installing solar panels can cut your energy bills, increase your property’s value, and reduce your carbon footprint. You also become less reliant on the energy grid.

How long will my solar panels last?

Most solar panels last around 25 to 30 years. After that, they still work but at reduced efficiency. Inverters and batteries might need replacing sooner, usually within 10 to 15 years.

Will solar panels still work if it’s cloudy or raining?

Yes, they still work in bad weather. Solar panels generate some energy from daylight, even when it’s cloudy or rainy—just at a lower rate.

How do I know what size solar system I need?

It depends on your electricity usage, your roof size, and how much sun your home gets. We’ll assess your needs and recommend the right system size for you.

How much can I save each month with solar panels?

Most customers save between 50% and 100% on their electricity bills. The amount depends on your system size and how much energy you use.

Do solar panels need regular maintenance?

Not much! Solar panels are low-maintenance. Just keep them clean and check your system now and then. We recommend a professional check-up once a year.

Can you install solar panels on any roof?

Yes, in most cases. We install systems on tiled, metal, and flat roofs using the correct fixings. If your roof isn’t suitable, we can discuss ground-mounted options.

Will having solar panels make my home more valuable?

Yes, solar panels can boost your home’s value. They make your property more energy-efficient and attractive to eco-conscious buyers.

Can I power my entire home with solar energy?

Yes, depending on your system size and whether you have battery storage. A well-designed system can meet all your home’s energy needs, especially with storage.

What warranties come with solar panels and parts?

Panels typically come with a 20–25 year warranty. Inverters often have 5–12 year cover. We’ll explain all warranties before installation.

What is battery storage and how does it help?

Battery storage lets you store extra solar energy to use at night or during power cuts. It makes your home more energy independent and helps you save even more.

Can you install an EV charger at my home?

Absolutely. We offer smart EV chargers that work alongside your solar panels, so you can charge your car using free solar energy.

Do I need planning permission for solar panels?

Most homes don’t need planning permission for solar panels. There are a few exceptions, like listed buildings or conservation areas, but we’ll check that for you.

Q: How do solar panels work?

Solar panels work by capturing sunlight and converting it into electricity through a process called photovoltaics.

Q: How much do solar panels cost for a residential installation?

The cost of solar panels varies depending on factors like system size, location, and equipment. Send us a message now with some details of your property and what you are after, and we'll come back to you with an initial estimate.

Q: What is the payback period for a solar panel system?

The payback period typically ranges from 5 to 10 years, but it varies depending on factors such as energy consumption, local incentives, and system cost.

Q: Are there government incentives for solar panel installations?

The government has unveiled plans to grant VAT relief on the installation of energy storage batteries.

Q: Do I need to replace my roof before installing solar panels?

It's recommended to have a structurally sound roof before installing solar panels.

Q: How long do solar panels last?

Solar panels typically have a lifespan of 25 years or more. They may continue to generate electricity beyond this period but at a reduced efficiency.

Q: What maintenance is required for solar panels?

Solar panels require minimal maintenance, although for best performance and reliability we recommend that you get your panels professionally cleaned at least annually. Periodic cleaning and ensuring that they are free of debris is crucial to continue to get the most from your solar panel investment.

Q: How much electricity will my solar panels generate?

The amount of electricity generated depends on factors such as panel efficiency, orientation, shading, and location. An installer can provide a more accurate estimate based on your specific situation.

Q: What happens on cloudy or rainy days?

Solar panels can still generate electricity on cloudy or rainy days, although the output will be lower compared to sunny days.

Q: Do I need a battery with my solar panel system?

Batteries are optional but can provide energy storage, allowing you to use solar power during the night or during power outages. They can increase energy independence.
