Caerphilly is a historic county borough in South Wales with a diverse mix of terraced mining villages, post-war semis, modern estates and rural properties. Many Caerphilly homes have solar panels fitted, and adding battery storage is the smartest way to maximise that investment. A home battery stores your surplus daytime solar energy and releases it in the evening when grid electricity is most expensive.

Our Cardiff battery team covers all of Caerphilly and the surrounding valleys. We have installed systems across the county, from compact 5kWh units in terraced homes to 10kWh and 13.5kWh systems in larger family properties. Caerphilly's elevated valleys often get excellent solar exposure, meaning plenty of surplus energy to store. A 10kWh battery can increase solar self-consumption from 30% to 70–80%, saving £350–£500 per year.
