FAQS about How much does a home solar power system cost

How much does a solar panel system cost?

Solar electricity is low carbon, renewable energy. A typical home solar panel system could save around one tonne of carbon per year, depending on where you live in the UK. That’s the equivalent of driving 3,600 miles, or from London to Bristol 30 times. The average domestic solar panel system is 3.5kWp and costs around £7,000.

How much does a solar panel cost in the UK?

The average cost of a solar panel in the UK based on a 350-watt panel is currently between £500 and £800. However, please bear in mind that this is the price for a single solar panel and does not include the professional installation or any other extras e.g. pigeon proofing. With that said, let’s explore some common solar installation scenarios

What costs should you consider before installing solar panels?

There are two other potential costs you should look into before installing solar panels, these are maintenance costs and repair costs.

How much does it cost to clean solar panels?

However, if you notice your solar panels becoming dirty – for example, bird droppings, or dust building up on them during a dry, hot summer – you should consider getting them cleaned. Solar panel cleaning by a professional will cost around £100, but you can do it yourself with a hose. How much do solar batteries cost?

How much does a 3.5 kWp solar panel system cost?

A 3.5 kWp solar panel system would typically require around 10 solar panels (at 350 W each) and cost between £5,000 and £10,000. *kWp stands for ‘kilowatt peak’. This is the amount of power that a solar panel or array will produce per hour in prime conditions.

Why are solar panels so expensive?

Panel efficiency: The more sunlight a solar panel can convert into electricity per sq metre, the more expensive it will be. Panel number: More solar panels means more materials, which means a higher cost. You can limit the number of panels you need by choosing highly efficient ones (although they may cost more).
