The solar photovoltaic roof system is an important part of the roof and is expected to work for 20 years.Because it is expensive, the warranty must be a key aspect of the purchase decision.In this article, we will discuss the warranty, the risks associated with the warranty and the strategies for how to offset them.
Solar panel: manufacturer warranty.Almost all solar panel manufacturers offer the same warranty.For solar panels, the industry standard is 5 years for parts and labor, with 20% of production falling by 25 years.However, it is well known that the typical life of solar panels is far more than 20-25 years.For example, solar farms built in their mid-70 s are still generating electricity.However, if you prefer additional guarantees, you can consider buying extended or covered panels that exceed industry standards (which will obviously cost more ).
Solar panels: waived warranty due to manufacturer bankruptcy.Panel manufacturers are likely to be out of business and will not comply with the warranty.In this case, considering the typical life ratio of photovoltaic panels is 20-For 25 years, warranty may not be required at all.In addition, all solar panels sold in North America and used for grid-connected installation must be strictly certified (UL, TUV, etc ).As a result, panel failures during the warranty period are a very rare event, and the possibility of manufacturers shutting down and not complying with the warranty is also very remote.
Inverter: manufacturer warranty.Similar warranty is provided by almost all inverter manufacturers.For inverters, the industry standard for parts and labor is 5 years.As we all know, the typical life of the inverter is about 15-20 years;Therefore, you may have to replace the inverter within 20 years (E.G.g.The FIT contract span in Ontario is not impossible.Therefore, you may consider purchasing extended warranty or inverter with warranty exceeding industry standards (these costs will obviously be higher ).
Inverter: waived warranty due to manufacturer bankruptcy.It is very likely that the manufacturer of the inverter will be out of business and will not comply with the warranty.In contrast to the solar panel industry with hundreds, if not thousands, of suppliers, the inverter industry has no more than 10 major players with mature market share.Therefore, the possibility that the manufacturer will suspend business and not comply with the warranty during the warranty period is very small.
Warranty for the installer.No industry standards.Installers can provide you with a manual warranty and extended warranty for photovoltaic system components.If you want to lock in your expenses and reduce the possible downtime of the system, it is feasible to extend the warranty.
Installer warranty: waived warranty due to installer bankruptcy.The installer may close the store and will not comply with the warranty.With a large number of players (80,000 installers in California alone), this is a very likely scenario.To offset this risk, please consider installers who work in solar or adjacent Enterprises (E.G.g.Roof workers, HVAC) for a long time.In this case, they have experienced the ups and downs of the economic reality, and in the long run they have a better chance of getting through the difficulties.
Roof warranty.It is almost certain that any roof penetration (which is almost certain for roof installation) will give up the roof warranty.In order to offset this risk while installing photovoltaic systems, consider dealing with a business that installs both roof and solar PV.
