Solar panel (Solar panel) is a device that converts solar radiation directly or indirectly through optoelectronic effect or photochemical effect through absorption of sunlight. The main material of most solar panels is silicon, but it is so costly that it has some limitations in general use.
Compared to ordinary batteries and rechargeable batteries, solar cells are more energy-efficient and environmentally-friendly green products.
The life span of the solar panel is determined by the material of the battery, the tempered glass, the EVA, the TPT and so on. In general, the service life of the battery board made by a little bit of material can reach 25 years, but with the influence of the environment, the material of the solar panel will be aging with the change of time. In general, the power consumption will decrease by 30% in 20 years, and 70% in 25 years.
