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.

For advice on upgrading or improving your existing solar PV system, call us to discuss the available options.

The following adaptations to your system design could increase your solar generation, improve your FiT payments and reduce your exported electricity, improving your self consumption:

  • Water heating diverters – use excess solar generation to heat your hot water immersion
  • solar edge panel optimisers – enhance the solar yield per panel & monitor your solar PV array
  • battery storage solutions – see our page dedicated to solar PV battery storage to find out more

“From the beginning of the order process we had a prompt and professional service in putting our quote together, kept in touch with us throughout our decision making without being pushy and was happy to answer all of our many questions! Not only this, but the price was very reasonable in relation to other quotes we received. Mike Costigan Ltd really appreciate getting your best price on the original quote rather than quoting higher so that it can come down when pushed! Following on from this, the scaffolding sub-contractors were also very good and your Solar PV  installation engineers were fantastic, polite, well presented and hard working. What more can you ask for? Please pass on our thanks to your team”
