Solar panels in Cambridge
Panels on the roof, a battery in the garage and a charger on the wall, designed together so the free electricity goes where it’s worth most.
How solar panels work
Sunlight falling on a panel energises its photovoltaic cells, made from layers of silicon, and they produce a direct current. The stronger the light the more electricity, but they don’t need direct sun and work on cloudy days too. An inverter turns that DC into the AC your home runs on.
| Part | What it does |
|---|---|
| Solar panels | Capture daylight and produce electricity |
| Inverter | Converts DC to AC for the house |
| Battery (optional) | Stores surplus power for later |
| Location | House roofs, garage roofs or the ground |

Solar with an EV charger
A solar-aware charger such as the myenergi zappi can run the car on surplus generation alone, and a diverter such as eddi heats your water with what’s left. We design the three together, so you’re not exporting power at a few pence a unit and buying it back at night.
