Solar is what we do. We're MCS accredited and a SolarEdge Partner, and we specify panels, inverters and battery storage from names like SOLARWATT, JA Solar and Fox — established manufacturers with real supply chains behind them, so the parts and the warranties are still there in ten years' time. From a single home retrofit to a full self-build specification, you'll deal with people who work nearby, know the local housing stock, and will give you a straight answer.
