If you generate more power than you use, the surplus can either be stored in your battery (if installed) or exported back to the grid. Some households may receive export payments depending on their tariff.

Battery storage is most effective when paired with Solar PV. In some cases, batteries can also be charged using off-peak electricity tariffs to lower running costs, depending on your energy supplier and tariff.

Solar PV can still be worth it without a battery, especially for households with high daytime electricity use. However, a battery usually improves overall value by storing excess power and reducing evening grid usage.

Savings depend on your system size, roof orientation, shading, and how much energy you use during the day. Adding battery storage typically increases savings because more of the energy generated is used within the home rather than exported.

Yes. Solar PV works in daylight and still generates electricity on cloudy days, though output is lower. In winter months, generation is reduced due to shorter days, but the system still contributes to household electricity usage.

Solar PV with battery storage is considered a premium upgrade because it reduces household energy costs, improves energy independence, adds long-term value, and supports lower carbon living. Batteries also improve performance by making solar energy usable when panels are not generating.

A solar battery stores surplus electricity generated by your solar panels during the day so it can be used later, such as in the evening or overnight. This increases self-consumption and reduces the amount of electricity you need to buy from the grid.

Solar PV (photovoltaic) is a system of solar panels that converts daylight into electricity for your home. Panels can be installed as roof-mounted systems (fixed above existing tiles) or as in-roof systems (integrated into the roof structure for a lower-profile finish). Solar PV helps reduce reliance on the grid and can lower electricity bills.
