Harnessing solar power in Cornwall

Solar panels are an increasingly popular way to generate electricity, thanks to how much you can save on your electricity bills with solar energy, as well as the environmental benefits. Solar panels are a clean, efficient way to harness the power of the sun and turn it into usable electricity – with maximum kilowatt hours (kWh) achieved between April and August in Cornwall.

The benefits of investing in solar

  • Solar panels will help you take control of your energy spending. By generating your own electricity with solar panels, you’ll be energy independent and protected against any changes in prices. Your energy costs will be considerably lower going into the future.
  • Solar energy is renewable and doesn’t damage the environment. By buying and installing solar systems in Cornwall, you can help drive the change to renewable energy. Renewable energy sources, such as solar, are sustainable, meaning they can continue to provide power indefinitely without causing environmental harm or using up the world’s finite sources such as coal and oil.

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

Factors like many panels are needed and the desired watt peak (Wp) will impact the total cost of a solar panel installation, but we’ve put together average costs for solar panels in Cornwall:

Number of panels 5 10 15
Kilowatts peak (kWp) 2.0 3.9 5.9
Annual kWh production 2000 kWh 4100 kWh 6100 kWh
Price without battery £3,978 £5,616 £7,699
Price with battery - £10,565 £13,526

It will cost around £5,600 on average to get 10 solar panels installed in Cornwall and 6 years to see a return on your investment. Every year, on average, households in Cornwall with this set-up could save £950 (without a battery) or £1,420 (with a battery) and, over a 25-year period, there’s an average saving of over £23,750 (without a battery) or over £35,500 (with a battery).

Solar panel FAQs

Is it worth getting solar panels in Cornwall?

Solar panels are an opportunity to take control of your energy spending and enjoy the benefits of generating your own renewable electricity. What’s more, The Smart Export Guarantee (SEG) allows households to receive payments for any surplus energy they export back to the grid, so you could earn money from your solar panels.

Do solar panels work on cloudy days?

Even when the weather is cloudy, solar panels produce power. However, we recommend you always work with professionals to achieve the right inclination and orientation of the panels. This is key for a high production of solar energy.

Do I need planning permission to install solar panels in Cornwall?

You will only need planning permission to install solar panels if you live in a listed building or in a conservation area. Otherwise, solar panels are considered a ‘permitted development’, so you generally don’t need planning permission to have them installed. You can always contact your local planning department for more information.

To calculate the ROI and discover annual profitability, we look at the following factors: installed power, total budget (including VAT), assembly budget, annual network consumption prior to the photovoltaic installation, annual production, percentage of self-consumption of the PV installation, system performance coefficient, percentage of energy poured into the network, average price per kWh, and price / kWh surplus compensation.
