In August 2019, Spirit installed one Tesla Powerwall for Mr S in Poole. It slots neatly inside the garage, especially when the matching Tesla is parked alongside.
The battery will store energy from a 4.2kWp PV system we installed in 2017. We estimate this will take the proportion of solar energy used on site from 34% to 83%, and would mean that 69% of the client’s annual electricity demand is supplied by solar.
Mr S chose to have the emergency backup feature with his Powerwall, which means he can keep the lights on during a power cut.
