Store electricity for use when the Sun goes down
Solar panels typically generate the most electricity when it's needed the least. Battery storage changes that by storing excess solar electricity for later use.
Not all solar systems need battery storage, and most homes don't have them.

Key considerations
- Batteries are designed to typically run on a 24 hours cycle. Meaning they charge in the day and discharge that night. Capacity is not sufficient to store electricity in the summer for use in winter.
- Battery technology is still expensive and primarily a mechanism for maximum solar self-consumption and battery back-up.
- Currently in Jersey and Guernsey there are no Time of Use tariffs to provide financial incentives in exchange for grid services.
- Battery supply and price has varied greatly. At present in Q3 2023 batteries are in good supply with UK suppliers.
- Installation price is largely dependant on the ease of installation and providing all equipment is in a centralised location.
- While other installers may install batteries in attics and habitable spaces. SunWorks only install Batteries should be located in non-habitable space or outside wherever possible in the unlikely event of a thermal issue with the battery.
