A lot of our customers who connect with us for solar panel installations ask about the shelf life of solar panels. Well, the answer to this question is 25-30 years. This is how long a good quality solar panel purchased from New York will last. You can gauge the life of a solar panel by the warranty the manufacturer offers.

But, the duration varies by different factors. Let’s discuss these factors in detail.

 Inverter replacement

Though you need not replace the entire solar system, it is crucial to get a new inverter after around ten years. This is when you are using an off-grid system.

The suppliers usually offer a warranty of ten years on inverters. Some of them let you extend the warranty by paying a little extra. This is a wise investment related to the solar system.

Battery maintenance and replacement

This is another important, and often ignored, aspect of the solar system. A good quality off-grid battery lasts for 5-15 years. To extend life, you need to focus on their maintenance. If you are using the lead-acid battery, recharge it fully after using it. The batteries get damaged if they remain uncharged for a long duration.

Quality of the panel

It also matters which brand you have selected when it comes to the life of solar installation in New York. The system should be engineered using best energy standards, some of which include surge suppression, DC power optimization, etc. You need to make sure that the solar panel degradation rate is low. So, what is a solar panel degradation rate? Let’s read below.

The degradation rate of solar panels

A lot of individuals ask us about the degradation rate of solar panels. The output of solar panels falls by about 0.8 percent per year.  This was reported in a study conducted by the National Renewable Energy Laboratory (NREL) in 2012. There’s even a term for this declination rate: solar panel degradation rate.

Other maintenance tips

Proper maintenance of the solar panel is as important as an installation with the help of a renowned vendor. Remove debris from the panels as soon as you notice them. Similarly, make sure snow is removed immediately. These things might sound trivial but they can create a substantial difference. It is also wise to ask a professional to check the health of your solar panels after every few years. Doing so ensures that the problems are rectified immediately.

The knowledge of all these factors ensures that your product lasts longer than you have expected. You can trust Promsun if you are searching for suppliers that provide finest quality solar panels with 25 years of warranty. Call us today for solar panel installation in New York.
