Solar PV Maintenance


Whilst your solar PV requires minimal maintenance, to ensure your solar PV array provides you with the most efficient energy generation we recommend that the system is serviced regularly. Several FIT licencees are also now requesting proof of maintenance during their 2-3 yearly meter reading checks.

Our maintenance service offers a thorough electrical & component check-up by a qualified electrician to ensure you continue to receive the best return on your investment.
