After the system s useful life your panels can go on producing electricity.

Degradation solar panels.

Have you ever looked at a roof that was 20 or 30 years old. Although crystalline solar power panels are often sold with 25 to 30 year lifespan guarantees those 30 year old modules won t be performing as well as they did on day 1. Manufacturers realize this so solar panels come with a power output or performance warranty that usually guarantees 80 production at 25 years. It s a good idea not to get these percentages confused.

Performance declines as solar cells experience degradation due to unavoidable circumstances like uv exposure and weather cycles. Because of solar panel degradation most panels production warranties change as they age. Solar panel degradation is defined as a process which occurs over time and leads to a reduction of performance of solar pv panels. Now imagine leaving your phone outside for even a few days let alone 20 years.

For many panels this is given as 2 to 3 in the first year and then 0 7 a year after that but it can be as low as 0 25 a year for some sunpower panels. Note these figures may have a minus sign in front of them as in 0 7 or 0 25. The degradation of solar pv panels should be considered when calculating the yield of a solar panel system. Solar panels show their age through performance degradation a decline in how much electricity they generate.

After ten years that percentage drops back to 80 for the remaining 15 20 years. Causes of solar panel degradation. Manufacturers typically guarantee 90 of the panels production until the first ten years.
