In previous articles we have discussed solar panel warranties and inverter warranties. In this final article about warranties we will discuss installer warranties and roof warranty, risks associated with them and strategies how to mitigate these risks.
Installer's warranty. There is no industry standards. Installers may offer you warranty for their labour and extended warranty for parts of a PV system. The extended warranty makes sense if you want to lock your expenses and reduce possible downtime of the system.
Installer's warranty: Waiving of warranty due to installer's bankruptcy. There is the possibility that the installer may go out of business and will not honor the warranty. With a huge number of players (80,000 installers in California alone) this is a very likely situation. To mitigate this risk, consider installers who have been in solar or adjacent businesses (e.g. roofers, HVAC) for a long period of time. In this case, they’ve navigated through ups and downs of economic reality and have much better chances of surviving in the long run.
Roof warranty. Any roof penetration (which is almost imminent for rooftop installation) almost certainly waives roof warranty. To mitigate this risk while installing a PV system consider working with a company that does both roofing and solar PV installations.
