Is it possible to store the electricity to use at night?
Yes you can, provided you install a battery storage system.
Battery storage systems store excess power locally for consumption later in the day or at night. We advise all our customers installing more than 6/7 solar panels to install a battery storage system. The SEAI also stipulate if you are installing more than 2KW of solar power you will need to install a battery in order to avail of the grant.
