After successfully installing a solar system, the next question for everyone is how to secure a solar system warranty. It’s a significant one-time investment, so you’ll want assurance. Most people choose a provider that offers a warranty, indicating responsibility for any future faults.
Warranty terms differ among manufacturers, generally covering a “product warranty” and a “performance warranty”. The product warranty covers manufacturing faults, while the performance warranty relates to energy production within the warranty period. It’s therefore advisable to read the warranty terms and conditions carefully before installation. Choosing a reliable installer matters too, as our look at why solar companies fail explains.
Why do we Need a Warranty?
A warranty assures clients that providers will rectify system faults hassle-free. Choosing a provider with solid warranty terms saves both money and time. For effective solar system maintenance when faults arise, opt for manufacturers offering accessible warranty cover.
What is a Performance Warranty and What Does it Cover?
Standard solar production declines by about 1% annually, but a performance warranty ensures it won’t degrade beyond 20% within 25 active years. In short, if your solar production drops below the guaranteed threshold, this warranty covers replacements or repairs.
What is a Product Warranty and What Does it Cover?
A product warranty differs from a performance warranty. It ensures repair or replacement for defects or a total breakdown, covering manufacturing faults and failures. Solar panels, designed for durability, usually offer a product warranty of 15 to 25 years. It addresses faulty wiring, parts or erosion through repairs or replacements, and manufacturers offer varying warranty periods. The brand you choose makes a difference here — our Longi solar panel reviews show how warranty cover can vary between makers.
Final Thoughts
Every manufacturer provides a different warranty cover and period according to the nature of the product. The standard period for a solar panel warranty is up to 25 years, but this depends heavily on the manufacturing and installing companies.
