A New Kind of Solar Installation, Built by Hand

Most solar installations are bolted on. Ours are built in — by the same craftsman who designs your oak frame.

Meet the person who actually builds your carport

William Jefferies is a master carpenter with decades of experience in traditional oak frame construction. He's spent his career learning the material's character — how premium French D30 and English oak respond to load, weather, and time. Every mortise and tenon joint he cuts carries the knowledge of generations, refined through thousands of hours at the workbench.

For years, William watched the solar panel industry grow. He saw the technology improve, the costs fall, and UK homeowners increasingly searching for solar carport and home battery storage solutions. But something troubled him: these systems were always bolted onto generic steel structures. Solar panels were treated as afterthoughts. Homeowners were left juggling multiple contractors for the oak frame, the solar installation, the EV charging, and the battery storage — managing their own builds and paying more than necessary.

William saw what nobody else in the market had connected: traditional oak frame carpentry and modern renewable energy aren't opposites. They're complementary. What if a handcrafted oak structure could be designed from the ground up to integrate solar roof tiles, home battery storage, and EV charging as core elements? What if homeowners could have one builder, one invoice, one guarantee covering everything from planning permission to final commissioning?

That's what Green Oak Solar is. It's a genuinely new product — not a solar company that subcontracts carpentry, and not a carpenter who subcontracts solar. William designs and builds the complete system himself. Because this is new, our founding customers get something rare: direct access to the person who creates their structure, at pricing that reflects the beginning of something, not the middle of a markup chain.

Why this works better than hiring three separate trades

"We've seen too many homeowners try to save money by buying an oak frame kit and managing the solar installation themselves. It rarely saves money, and it never saves stress. When the structure and the energy system are designed together, everything fits. When they're not, you spend months coordinating trades."
