Will solar panels last 25 years | Sunerisepv.com
Can solar panels really last up to 25 years? The answer is yes. Solar panels are not only very reliable, but also their life has increased significantly in the past 20 years. The advantage of solar panels is that they require relatively little maintenance. There is usually no need to clean solar panels regularly, unless your area is particularly prone to dust, dirt, pollen or sand due to drought. Like most technologies, solar panels naturally produce less energy over time. This reduced power output is called degradation rate. The median degradation rate of solar panels is about 0.5%, which only means that the energy output of solar panels will decline at a rate of 0.5% per year. After 20 years, your panel should still work at about 90% of its original production. Although solar panels usually require little maintenance, it is still important to check your solar panels from time to time and monitor their performance. Here are some tips to make sure your solar unit is ...
