What do Downley homeowners ask about battery storage?

Home battery storage starts from around £3,495 installed in the Chilterns. The price varies based on battery capacity, brand, and the complexity of the installation. Common home battery sizes are 5kWh to 15kWh. We give a fixed price at the site survey.
Battery storage without solar can be used with time-of-use electricity tariffs: charging from the grid at night when rates are low and discharging in the evening when rates are high. This can save money on some tariffs, but the returns are lower than with solar. We advise at the site survey based on your actual tariff and usage.
Yes. We retrofit battery storage to most existing solar PV systems. We check your inverter compatibility at the survey. Most inverters installed in the last 10 years are compatible, but some older systems may need an upgrade.
Most home batteries come with 10-year warranties and are designed to retain at least 70% of their original capacity after 10 years. Quality brands like GivEnergy, Growatt, and SolarEdge have strong track records for longevity.
The right battery size depends on your daily electricity usage, your solar system size, and when you use most electricity. For a typical 3-bed home with a 4kWp solar system, a 5 to 10kWh battery is usually the most cost-effective. We calculate this specifically for your home at the survey.
