The lifespan of the solar cell module is determined by its power generation efficiency, and the degree of combination of the PN junction and the purity of the silicon wafer determine the intensity of the generated electrical energy by the solar cell under the same light. Over time, the PN junction will continue to break down, so efficiency will continue to decrease. After 15 years, the conversion efficiency will be over 90%, and after 25 years, it will drop to around 80%. Therefore, the lifespan of the solar cell module is basically more than 20 years.
How long does a solar generator last?
It depends on the location and maintenance, whether it is outdoors or indoors, such as a power generation system or a solar power plant. If it's outside, it usually takes about ten years. , it's good if it can be managed for five years. If the interior maintenance is good, it will last fiveze years, generally ten years maximum. . . . In addition, the lifespan of the plateau and the continent is different. It's hard to say that things break down after one or two years.
How many years is the lifespan of solar panels?
The lifespan of modules conventional solar panels are now guaranteed for around 25 years. The solar intensity requirement is related to the component material. Generally, the standard light intensity of silicon solar modules is 1000W/mm2 and can be used in visible light. Wavelength range. Thin-film solar cells have better low-light effects and can also be used under ordinary lights.
The lifespan of ordinary monocrystalline and polycrystalline solar panels is about 5-8 years.
It is possible that some of the best maintained panels can be used for more than 10 years, butis over time, the power generation efficiency of these power generation panels will weaken and the effect will get worse.
So after the solar power generation panel has been used for a while, it needs to be replaced. However, with the continued development of technology, I believe that more advanced power generation panel products will become available. available in the future, and the price may also increase. It will be cheaper and new energies will then become the main trend.
