How much does it cost to install solar panels UK?
Solar panels for the average household in the UK cost roughly between £4,000 and £6,000. A family of three typically needs a 3kW solar PV system, which consists of about 10 x 300W panels, and requires around 20m² of roof space.
How many solar panels do I need to power my house?
The typical homeowner will need 28 – 34 solar panels to cover 100% of their energy usage (dependent on location and roof size). To get these numbers, we used high and low panel production ratios to calculate how many solar panels are needed on average
Can you get free solar panels UK?
Companies offered free solar panels in the past, but this service is not available in the UK any longer. As solar panels are becoming more affordable, the government has drastically reduced the Feed-In Tariff (FIT). This has made the free solar panels scheme unprofitable for many companies.
Does Solar Enegy Save Money?
Speaking purely from a financial point of view, the answer is a resounding yes. Of course beyond the financial, there are many other environmental benefits to be gained from installing solar, installing residential battery storage, driving an electric vehicle etc. Not least because they all contribute directly or indirectly to tackling air pollution and the climate crisis.
Back to the financials. The solar subsidy may have fallen, but so has the cost of the technology. Overall the cost of domestic solar electricity is now around 8p per kWh. This is well below the 16p average domestic import cost from the grid (which, by the way, increased by 6% in the last 12 months…).
The economics of solar in 2020
A typical 4 kWp solar system (10-13 panels) now costs around £5,500 inc 5% VAT. There will be some maintenance costs over the life, and a probable inverter replacement required, total cost around £1,750 in today’s money. So the true all-in cost of the system is around £7,250.
On average a system will generate an average of around 3,500 kWh a year, allowing for a modest degradation over time. In its 25 year life, it is expected to generate about 88,000 kWh of electricity.
The unsubsidised cost of solar
Ignoring export tariff payments for now, that means each kWh generated costs 8p:
kWh from 4kWp system over 25 years: 88,000
System cost including 5% VAT: £5,500
Lifetime maintenance cost (present value): £1,750
Total system cost: £7,250
Cost per kWh: 8p
