How Long Do Solar Panels Last? A Guide to Navigating Solar System Warranties
Once you decide to go solar, the next step is to do some research to see what warranties and other guarantees installers and providers will offer you. Will your installer stand behind their work? What about the individual components? What type of performance should you expect over time, and will your provider compensate for lapsed levels? All of these are serious questions that deserve to be answered in detail.
To make sure you get the most out of your conversion to solar power, we have put together a guide to what to look for when researching warranties and guarantees about solar panel equipment, installation, and power production.
How Long Is Your Warranty For?
Most solar power system manufacturers warrant their equipment for about 10-12 years. These warranties guarantee that your panels will work at a certain power level for a set amount of time. For example, a solar system warranty might only guarantee full power for the first 10 years, and then allow a lapse to around 80% of the original power level after the warranty expires.
For a more sustainable and cost efficient alternative, try to find a manufacturer who will provide you with a longer warranty. For example, Enphase’s warranty is for 25 years instead of 10-12 LA Solar Group covers all systems with an extended 25-year workmanship warranty, regardless of original manufacturer.
LA Solar Group also provides customers with an extremely accurate projection of power output with every solar system proposal. We project power output over a 25-year timeline, so you’ll know what to expect over the lifetime of your system, not just the first 10 years. Our systems are monitored to ensure power production of the promised amount. Any lapse in power is reimbursed for the difference at $0.19 cents per kwh.
What Else Is Your Warranty Covering?
Another thing to consider is how much of your solar system is actually covered under warranty. Some warranties cover only the panels or the power production levels, and do not extend to individual components such as power optimizers or mounting equipment.
A comprehensive solar system provider will offer equipment from high-quality industry vendors and then include all that equipment under the warranty. For example, LA Solar Group works with the following industry leaders to provide and cover the following:
- Hyundai, LG, Panasonic, and SunPower panels;
- Enphase, SMA, SolarEdge, and SunPower string and micro-inverters and power optimizers; and
- Quick Mount PV, ProSolar TileTrac, and Ironridge mounts and rails.
What About Installation and Workmanship Warranties?
Also be sure you ask about installation and workmanship warranties. These cover system design and installation, and will generally run between 1-10 years. A good provider will be willing to back up their work by promising customer satisfaction. Similarly, a trustworthy installer will be upfront with you if they use subcontractors and be willing to cover their work under warranty as well.
LA Solar Group’s workmanship guarantee is good for every part of the system for 25 years. Moreover, we guarantee every project will be installed and activated within 60 days from the time you sign the service agreement. Our team has built strong relationships with city and county offices to help expedite every solar project, with proactive follow-ups and project tracking. Our permit and interconnection team works every hour of the day to navigate the approvals needed to get your solar system up and running as quickly as possible.
Labor is also covered under our extended 25-year warranty. If anything goes wrong with your solar system, we’ll visit, access, inspect, repair, and replace it without any cost to you. Your system is also supported through our always-available customer service solutions team and website.
Are You Covered For Roof Damage?
A properly-mounted solar system will not cause leaks, but what happens if your roof does start leaking after installation? Most installers will guarantee the solar paneled area of your roof against leaks for a period of about 10 years. You should always make sure this guarantee is included in your coverage, and that your installer has some kind of roofing certification.
LA Solar Group is licensed for solar, electrical, and roofing work by the California State Licensing Board, and we have a $1,000,000 general liability and insurance bond. We specifically guarantee every inch of roof that our equipment is installed or mounted on against leakage for 10 years. Additionally, if you’re having roofing work done when you go solar, we’ll include a 25-year material warranty for any work done on our behalf.
What Will A Good Warranty Cost?
Very few installers offer price-matching warranties. LA Solar will match or beat any quote on equivalent solar systems offered in the California area. We’re proud of our work and are happy to stand behind it. Should you have any questions about specific coverage, or about any other aspect of going solar, we want to hear from you.
