Solar Answers: How Long Do Solar Panels Last in Colorado?

Updated: Dec 23, 2019

As one of the top rated solar companies in Colorado & Wyoming, not a day goes by without one of our potential customers asking us, "What is the lifespan of your solar panels?"


The answer may come as a surprise to some but the average lifetime of most solar panels is between 25-30 years, but quality equipment can last 40+ years. During this lifespan, solar panels have a degradation rate of <1% each year. This means, that in 25 years after installation, most solar panels will still be operating at over 85% of the efficiency as the day they were installed.



So what do we do with old solar panels? We donate them! With panels still producing electricity into their late thirties, we donate old functional PV panels to organizations that provide electricity to those who cannot afford it. For more information on what can be done with used solar panels, here is a great article from Solar Power World.


There is a common misunderstanding that solar panels are a very expensive technology. With the initial sticker shock of the total cost of an installation sometimes turning people away, we often encourage homeowners to put the price in terms of their electricity costs over the next 20 years. With utility rates rising every year, and increased home value, solar will almost always come out as the cheaper, independent option for residential electricity.


We design your system to make sure they last, and with the industries longest warranties, we deliver on that promise.  We use American made panels and the industry's best equipment to make sure you get the most out of your investment.
