subject: The Lower Cost Of Solar Panels Helps To Make Solar Power A Reality [print this page] Another consideration that affects the cost of solar panels is their warranty. Most modern solar modules are guaranteed for 10 years or more against defects and failure. Even though this may seem like a good warranty, most panels don't fail completely. Failure in a solar panel typically happens gradually over time and will slowly lower the output power that the panels produce for the home. This slow decay in their output power means that they haven't actually failed, they're just producing less power. Some of the newer solar panels for homes provide a basic warranty that covers any failures to the panel itself as well as an additional warranty to ensure it continues to produce a given amount of power over its useful life. This type of double warranty is important since it will typically ensure the replacement of a panel that falls below a certain percentage of output power over time. Even though solar panels that offer this type of warranty may be more expensive than others without the warranty, this peace of mind can easily justify the solar panels price.
