We install battery systems that store electricity generated by solar panels during the day so it can be used at night. The systems can also be charged using cheap off-peak elecricity to further reduce costs and help balance the grid. We install systems that provide grid back-up such as the Tesla Powerwall 2.
We are Tesla, Maslow, Powerflow and Victron approved installers and have fitted over 60 systems including 35 systems for a trial of solar battery systems which was short listed for an award and 14 Tesla batteries for a Nottingham University trial.
