“We own a 5 bedroom 3 storey house with detached garage offset away from the house. We wanted off-grid capability and Matt recommended a Tesla Powerwall 3 coupled with a 13.3 Kwp solar system comprising of 28 European 475w glass-covered Bi-Facial panels. The Powerwall is positioned on the garage wall with the cabling routed back to the house via a trench around the edge of the garden. Alongside this we also required some roof repairs. Matt offered a seamless service, project managing the scaffolding and roofing repairs using small highly skilled sub-contractors. We have a system we are proud of”

Highlights
“Matt from Windsor Solar designed and installed our new solar system in May 2023 and on the anniversary I wanted to record how happy we are with the system and setup. For roughly 6+ months a year we are basically off-grid, using generated and stored solar, even heating all our hot water with excess solar. Our energy bills are a fraction of what they were and I think the payback is shorter than we ever expected for such a top end system. Great communication throughout the project, thanks again Matt.”

Electrical work in homes in England & Wales should be done by a registered competent person who can self-certify it meets the Part P safety rules. Check they're on the official register.
Check the electrical registerIn England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations. Confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done. It is your proof the work is safe and compliant, and you will need it if you ever sell.
