A high-quality solar power system can last a long time. The high-efficiency, premium-quality solar panels and inverters used by SUNation for resident solar systems have a 10- to 25-year warranty and can produce plenty of power for that 25 years. After that, there may be a minor decrease in production annually at only less than half a percent per year.
How to Make Your Solar System Last
To make your solar system last longer, it is important to remember to replace the inverters and batteries when needed and account for efficiency loss. If your system output decreases or your energy usage grows, it’s possible to add capacity to your system, as long as the used and new parts are compatible.
