As we pass the summer solstice and the days begin to shorten, it might feel like solar’s moment has passed for the year. But at RenewSolar, we’re here to tell you that now is a smarter time than ever to think about installing solar panels in your UK home or business!
The Solar Surge: UK Trends You Can’t Ignore
2025 has been a monumental year for solar in the UK. We’ve just experienced the sunniest spring on record, leading to a phenomenal 42% surge in solar power generation in the first five months compared to last year. In fact, 57,000 rooftop solar systems were installed in the UK in Q1 2025 alone – the best start to the year since 2012! This incredible growth means that solar is no longer a niche technology; it’s a mainstream, powerful contributor to our national energy mix. The UK’s total solar capacity exceeded 18 GW as of March 2025, with government aims to reach 45 GW by the end of the decade.
Average System Size: For domestic installations, the average solar system size in the UK is around 3-4.5 kW, often paired with battery storage to maximise self-consumption.
Beat the Winter Blues & Future Price Hikes
We all know the dread of winter energy bills. While solar production naturally peaks in the sunnier months, installing now means you’re perfectly positioned to capitalise on the spring and summer sun of 2026 from day one. Think of it as planting a seed for future energy independence!
And here’s another crucial point: energy prices are predicted to rise again. While the energy price cap is set to fall slightly in July 2025, forecasts suggest it will increase again in October 2025 and into January 2026. By installing solar now, you can lock in your energy generation costs and significantly offset these future increases, giving you greater control over your household budget.
The RenewSolar Advantage: Value, Flexibility & Expertise
At RenewSolar, we’re all about making solar accessible and affordable. We pride ourselves on offering some of the lowest prices in the UK for both hardware and installation. But it’s not just about cost; it’s about making solar work for you.
- Smart Timing for Installation: While summer sees peak demand (and sometimes higher prices/longer wait times for installers), installing in the cooler months or early spring often means quicker installation times and potentially more competitive rates. You’ll be ahead of the curve and ready to harvest that abundant spring sunshine!
- Beyond the Standard: We’re not “product-locked.” This means you can even supply your own hardware, and we’ll provide our expert installation service. We handle everything from standard on-grid systems to complex off-grid solutions, and we’re even equipped for unique projects combining solar with hydro and wind.
- Project Managed Perfection: Forget the technical headaches. We project manage your entire installation and configuration, ensuring every detail is reviewed to guarantee your system is optimised for your needs and fully compliant with UK regulations (including G98 and G99 applications).
- DIY Support: For the hands-on homeowner, we offer comprehensive support services for DIY installations, ensuring you have the guidance you need.
Looking Ahead to 2026
The outlook for solar in the UK remains incredibly positive. With new legislation coming into play, such as the requirement for solar panels on all new homes in England by 2027, the demand and infrastructure for solar are set to expand significantly. Experts forecast continued growth in solar capacity throughout 2026 and beyond, with solar expected to play an increasingly dominant role in our energy landscape.
