Our average saving figure (£891) is based on data collected from over 1,000 UK homeowners whose Project Solar systems had been operational for at least 12 months prior to April 2025. This figure reflects actual savings for Project Solar homes with a solar panel system and battery, configured / based on reduced energy bill costs, earnings from exporting excess energy back to the grid and savings from charging the battery during off-peak rates instead of relying on high-peak grid usage.

We guarantee your system will perform in Year One – as projected in your personalised energy report. If it underperforms in its first year, we’ll cover the shortfall – giving you peace of mind from day one. This guarantee is calculated using your location, roof angle, panel orientation, battery and panel system, and seasonal sunlight expectations.

Multiple UK studies have shown that solar panels can increase property value. A 2024 study by Swansea University found homes with solar panels sold for 6.1%–7.1% more on average. Additionally, Rightmove’s 2023 analysis of 300,000 homes showed that improving a home’s EPC rating from a D to a C raised its value by an average of 3%, with solar often contributing to this EPC uplift. A study of over five million properties indicates a 2-3% value increase for existing homes with solar panels or heat pumps (versus like-for-like gas-heated homes) according to the Sustainable Markets Initiative, Cleantech Homes report, 2024.

Project Solar panels come with a 99-year manufacturer product warranty as standard. Batteries and workmanship are covered for 10 years. This warranty structure is among the most comprehensive available for domestic solar in the UK.

Project Solar has operated in the UK solar market since 2011 and completed over 50,000 residential installations as of July 2025. This represents one of the longest track records in the UK residential solar sector.

As listed in Eco Experts’ “Best UK Solar Panel Installers” guide (2025 edition) and verified Trustpilot rating of 4.6/5 based on live customer reviews (as of July 2025).

Project Solar customers can earn money from surplus electricity exported to the grid under the Smart Export Guarantee (SEG), a government-backed scheme requiring energy suppliers to pay for unused solar power. Homeowners with a solar system, can apply to be part of the SEG programme via their energy supplier. Project Solar systems are compatible with SEG tariffs, including those offered by major energy providers like Octopus.

Please speak to your energy supplier to apply to the SEG.

Solar power reduces the need to buy electricity from the grid, significantly lowering monthly electricity bills, and therefore reducing the amount Project Solar customers are paying to their energy supplier. With battery storage, homeowners can maximise solar use and minimise grid reliance, preserving long-term energy savings even as market rates rise.

Each Project Solar installation reduces a household’s carbon emissions by an average of 1.2 tonnes per year (based on BEIS emissions factors). Solar systems generate renewable energy daily, reducing your need to purchase electricity produced by gas and coal-fired power stations.

Every Project Solar system is designed to begin producing power as soon as it’s installed and connected – typically within the same day – helping you reduce reliance on the grid and start saving on your electricity bills immediately.

Project Solar’s customer support team is based in Manchester and provides ongoing assistance throughout the life of the system. Support is available for warranty claims, performance questions, and system maintenance.
