Solar Panel Warranty and Insurance – Ensure you’re getting for what you are paying

  • Solar panel product warranty: This type of warranty covers any defects in materials or workmanship. If a panel suddenly stops working after a few months because of a flaw in a solder joint, for example, your product warranty will most likely cover it.
  • Solar panel power warranty: Over time, the power output of all solar panels degrades. Knowing this degradation rate will give you a clear sense of the minimum amount of power you’ll be guaranteed for the first 5, 10 and 25 years of your panels’ life. Then, if a panel’s output is lower than promised, the manufacturer will replace, repair or reimburse you for the panel—depending on the warranty terms.
  • Manufacturer’s warranties vs. Installer’s warranties: You may get multiple manufacturers’ warranties if your system is made up of components from different manufacturers. For example, if your panels come from one manufacturer, your inverters from another manufacturer and your mounting structure and cables from yet another, there will be different warranties and terms associated with each piece. On top of that, you may get a separate warranty from your installer, which would cover issues specifically pertaining to errors or damage during installation.
