Solar Battery Installation in Welwyn Garden City, Hertfordshire
If you have solar in Welwyn Garden City but still buy most of your evening electricity from the grid, a battery could make a real difference. One enquiry can reach up to four storage specialists covering Welwyn Garden City and nearby parts of Hertfordshire, who can look at your system and quote for a suitable battery.
How a Solar Battery Works
When your panels produce more than the home needs, the extra goes into the battery rather than being exported. In the evening, the battery discharges to cover lighting, cooking and TV. With an off-peak tariff, the battery can charge cheaply overnight too, which keeps it useful through the darker months.
Adding Storage to Existing Panels
Many enquiries in Welwyn Garden City come from owners of systems fitted years ago. The simplest route is usually an AC-coupled battery alongside the current inverter, while a hybrid inverter replacement suits systems whose inverter is nearing the end of its life.
What Battery Installers Will Need to Know
- The make and model of your current inverter
- How many panels you have
- Your electricity tariff and annual usage
- The preferred location, such as garage or utility room
- Whether you want backup power during outages
- Upcoming changes to your electricity use
