Solar Photovoltaic Installation Warranties

After Sales Support and Maintenance

Although Solar PV is reasonably ‘fit and forget’ technology, certain parts such as the inverter may need servicing or have to be replaced in the lifetime of the panels.

Cymru Solar provides optional servicing and/or maintenance contracts at additional cost.

Inverters warranty

Inverters are the single most expensive component to replace in your solar panel system. This is a component that should both be rated correctly to handle the calculated capacity and be of a high enough quality to compensate for the initial high cost.

A good quality inverter can last upwards of 15 years whereas a poor quality one will only last 5, with top manufacturers claiming over 20 years usable lifespan!
