Sol4r Energy systems start from £4,999 for a residential installation and range up to £14,000+ for larger systems with battery storage. All residential solar installations in the UK currently benefit from 0% VAT (until at least 2027). We offer free property surveys and no-obligation quotes to give you an accurate price for your home.

Most residential installations are completed in 1–2 days on site. The full process from initial survey to installation typically takes 2–6 weeks, depending on scheduling and whether planning permission is needed. Larger commercial projects take longer and are scoped individually.

Yes. Solar panels generate electricity from daylight, not direct sunshine or heat. Winter output is typically 10–25% of summer levels due to shorter days, and cloudy conditions reduce output to roughly 10–30% of peak capacity. A well-designed system still produces meaningful energy year-round. Rain can actually help by cleaning dust from the panel surface.

Standard grid-tied solar systems switch off during power cuts for safety reasons. However, certain battery systems — like the Tesla Powerwall 3 and Sigenergy — include backup functionality that keeps your home powered during outages. Sol4r Energy can design a system with backup capability if this is important to you.

Battery storage increases self-consumption from around 45% to 70–85%, meaning you use more of your own energy instead of exporting it for a low rate. A 5–10 kWh battery typically adds £2,500–£5,000 to the system cost. For most households, this accelerates payback and reduces grid dependency significantly.

Sol4r Energy is based in Sutton, Surrey and installs solar panels nationwide across the UK. We have completed projects in London, Surrey, Sussex, Brighton, Epsom, Glasgow, Shropshire, and many other locations. Whether you are in England, Scotland, or Wales, we can arrange a free property survey.

Sol4r Energy uses an in-house installation team (not subcontractors) with an average of 7+ years of industry experience. We have delivered both residential rooftop systems and utility-scale projects like the Laceby Manor solar farm, meaning customers benefit from the same engineering standards used on major projects. Every installation includes MCS certification, up to 30-year warranties, and 2 years of free annual maintenance.

Yes. Solar PV finance is available exclusively through Phoenix Financial Consultants Limited, an FCA-regulated credit broker. All finance is subject to application, status, and credit approval.

Sol4r Energy provides up to 30-year panel performance warranties, 10-year battery and inverter warranties, and up to 10-year workmanship cover. Every new installation also includes 2 years of free annual maintenance for complete peace of mind.

Yes, through the Smart Export Guarantee (SEG). UK energy suppliers must pay you for surplus electricity you export to the grid. Rates vary by supplier, typically 3–15p per kWh. All Sol4r Energy installations are MCS-certified, which is required to qualify for SEG payments.

Most residential rooftop solar installations in England fall under permitted development and do not require planning permission. Listed buildings, conservation areas, and some flats or commercial properties may need additional approvals. Sol4r Energy handles planning applications where required as part of the installation process.
