What the installation is
Solar panels generate while light is on the roof. A battery stores some of that electricity for later in the day. It can be fitted with a new array or added where an existing array and inverter can accept it. The quote names the battery scope, any inverter changes, the materials, and the labour.
Capacity follows the survey of that house and is written in the quote. Where the panels are already on the roof, see adding a battery to existing solar. The longer note is home batteries with solar PV. The workshop is Unit 2b Eastfield Industrial Estate, Penicuik, EH26 8HA.
