Evaluating and comparing the warranty coverage of each manufacturer can help assure you that your service and support needs will be covered in the unlikely event that a solar panel problem occurs post-installation. Manufacturers’ warranties are therefore an important complement to performance, quality, and durability metrics in assessing not only a panel manufacturer’s technical specifications, but also its business practices.
