Photovoltaic Solar Panels
Why Solar Panels Make Sense in 2025
Clean, Efficient & Growing
Solar power now contributes around 5% of the UK's annual electricity and, on sunny days, can reach over 30% of national energy demand
With over 1.5 million UK homes already equipped with solar panels and new-build adoption on the rise, solar is becoming the go-to eco-friendly energy choice
Lower Costs, Better Value
A typical 4 kW solar PV system (enough for many UK households) costs between £6,600–£8,100 and can save around £1,274 annually, reaching a break-even point in about six years.
Even smaller setups—for example, a 3.5 kW system—can cost about £6,100, with potential savings of £190 to £350 per year.
Support and Incentives
There’s 0% VAT on solar panels and batteries in Great Britain until March 2027, lowering upfront costs.
The Smart Export Guarantee (SEG) lets you earn money back for surplus electricity you return to the grid—typically 1.5–12 p/kWh as of August 2025.
Government Backing
The Solar Roadmap outlines plans to scale up solar energy to deliver 45–47 GW by 2030, helping households save about £500 annually.
New homes in England are now commonly built with solar as standard—42% of new-build homes have solar panels, compared to just 13% a year earlier—driven by evolving energy-efficiency standards.
What This Means
Solar panels are not just eco-friendly, they are financially smart. With efficient systems, reduced VAT, and growing government support, return on investment is faster than ever. You could slash your energy bills, earn for excess power you export, and boost your home’s value, all while helping the planet.
