Cathays is one of Cardiff's most energetic neighbourhoods, home to a mix of student houses, Victorian terraces, Edwardian semis and professional rentals. Many Cathays properties have solar panels, and adding battery storage is an excellent way to maximise their value — whether you are an owner-occupier, landlord or student tenant splitting bills.

Our Cardiff battery team has installed systems across Cathays, from compact 5kWh units in shared student houses to 10kWh systems in family semis. For landlords, battery storage increases rental appeal and can justify higher rents as tenants benefit from lower energy bills. For owner-occupiers, a battery typically adds £300–£500 per year in savings when paired with solar.

Cathays properties often have compact roof spaces but excellent sun exposure, making high-efficiency panels and batteries a great combination. We understand the unique needs of Cathays residents — from budget-conscious students to property investors looking for long-term value.
