The project

What we were asked to do

The homeowners had recently purchased an electric vehicle and were looking to reduce their running costs by generating their own electricity. Their south-facing roof was well-suited to solar, and they wanted the EV charger integrated so it could draw on solar surplus during the day.

We carried out a full site survey, assessed the roof structure and orientation, and recommended a 4kWp system with a Zappi charger — allowing the car to charge directly from excess generation rather than drawing from the grid.

Customer testimonial

What the customer said

We always ask customers to share their experience once they’ve had a chance to see the system in action.

From the first survey to the final handover, BGreen were professional, tidy, and genuinely helpful. They took the time to explain exactly what they were installing and why — no hard sell. The app is brilliant, and we’ve already seen a real difference in our electricity bills. The Zappi charger is a game-changer — the car charges itself on sunny days for free.
