How much does a solar PV system cost?

According to the Energy Saving Trust, the average domestic solar PV system is 3.5kWp (kilowatt peak – the amount it will generate when working optimally) and costs about £7,000. Check out our guide to solar panel costs for a more in-depth breakdown of system prices and savings.

How much roof space does a solar PV system need?

Depending on the system you use, you can expect to require around 8m2 of roof space per kWp. As a rule, 1kWp of solar PV panels installed on a south-facing roof at a good pitch will provide around 800-1,000kWh of electricity per year.

Should you buy a solar PV system for your home?

Well-chosen solar panels can provide a reliable source of renewable electricity for decades, helping to slash your electricity bills and cut your carbon footprint. But buying an inappropriate solar PV system for your home could leave you out of pocket.

How much electricity does a household solar system provide?

Household solar panel systems are typically up to 4kWp. We spoke to more than 2,000 solar panel owners about the size of their system and how much of their electricity it provides in summer and in winter. Which? members can log in to see this data.

What are solar panels?

Solar panels, the heart of solar energy systems, offer a remarkable way to generate electricity while reducing your carbon footprint. But what exactly are solar panels, and how can our dedicated Renewables Team of experts guide you on this transformative journey?

How do solar photovoltaic panels work?

Solar photovoltaic panels transform free energy from the sun into electricity. This is then converted from a DC current to an AC current via an inverter, to make it suitable for household use. The panels capture energy from the sun and convert it into DC electricity via groups of photovoltaic (PV) cells.
