Component function assurance

The function guarantee of china 405w 410w solar module is generally required to be 25 years, although some manufacturers increase the warranty period to 30 years. When installation companies talk about a 25-year warranty on a solar panel, they generally only consider performance, not other aspects of the system or the panel itself, and more component suppliers are promising 20 years.

Component Product Warranty

Typically, unlike performance assurance, most component products come with a warranty period of 5 to 10 years, depending on the company installing the component and the products it supplies. This is a far cry from, and shorter than, component performance warranties, but many people mistakenly assume that component product warranties are the same as component performance warranties. This may lead them to think that their guaranteed coverage is larger than it actually is, and for a longer period of time.

Inverter Warranty

Inverter warranties are almost always five years, but there are sometimes upgrade options that extend the warranty to 10 years or more. These upgrades are generally not free and may be available at the time of sale or at the time of installation. Other guarantees can offer higher value if they cost less, but it's important to understand how much the cost will go up.
