Harnessing solar power in London

As awareness around climate change grows, solar panels are becoming an increasingly popular option for homeowners across the UK, including in London. They allow you to take advantage of the natural sunlight at your property, generating clean, sustainable energy that reduces your reliance on fossil fuels.

As well as their eco-credentials, solar panels allow homeowners to lower their energy bills, as you can generate and use your own power before purchasing energy from the national grid. This means you can reduce the amount you spend on fluctuating price electricity units, and, when paired with a battery, allows you to take advantage of off-peak prices for any units you do buy.

At Otovo, we connect you with local, trusted suppliers, so that you can be assured you’ll get the best solar panel setup for your money. We offer customised quotes that take into account your geographical location, the orientation of your home and your energy needs, and work with you to create the most effective solar array for your budget.

Whilst many people believe solar panels are only useful during the summer months, solar panels in London can generate power year-round, producing around 924 kWh of energy in April and May combined, and around 640 kWh collectively in September and October.

The benefits of investing in solar

  • Clean, sustainable energy. Solar panels harness the natural energy of the sun to create power. There’s no need to burn fossil fuels which are harmful to the environment, meaning that you can reduce your carbon footprint and know you’re doing your part to fight climate change.
  • Reduce your energy bills. Rising energy costs can be worrying. Solar panels allow you to reduce your reliance on the grid, giving you a year-round supply of electricity, even on cloudy days. Even if it’s not quite enough to fully power your home, any solar you generate will regularly reduce your energy bills.
  • Make the most of your home. Your roof is a previously untapped resource. Installing solar panels allows you to make the most of your property and reap the rewards of natural sunlight.

How much does it cost for solar panels to be installed?



At Otovo, we offer a range of options to suit a variety of homes and budgets, and our experts are on hand to talk you through every step of the process. However, we know that it can be helpful to have a ballpark figure, so that you can understand if solar panels might be right for you. We’ve put together a general price guide for London, including expected annual production.

Kilowatts peak (kWp) 1.9 kWp 3.9 kWp 5.8 kWp
Annual kWh production 2000 kWh 4000 kWh 6000 kWh

As well as generating energy for your own use, you’ll also benefit from being able to sell any excess energy back to the grid, thanks to the Smart Export Guarantee. Even if you’re out at work or not using much electricity during the day, you’ll still be able to benefit from your investment.

Alternatively, adding a battery to your solar panel setup will allow you to store energy for when you need it, rather than having to use it in sunlight hours. On average, homeowners with a 4.2 kWp solar panel setup and a battery save £1,384 per year in London, compared to £949 without a battery.

Solar panel FAQs



Do I need to apply for planning permission for solar panels in London?

Most properties won’t need planning permission to install solar panels, as they’re considered a ‘permitted development’. However, if you live in a listed building or conservation area, you may need to apply, depending on your local council rules. If you’re unsure, check with your local planning authority in London.

How long do solar panels last?

Solar panels are an investment, so we understand that you’ll want to be sure they’re going to last. Fortunately, modern solar panels can last up to 30 years, and many will last longer, meaning that you can be sure you’re getting the most for your money.

How many solar panels do I need?

The number of solar panels you need will depend on how much energy your household uses, and the space that you have available. Our experts will be able to talk you through all the options to create a solar panel array that gets you the best energy output for your money.
