Do Different Solar Battery Types Have Varying Life Expectancies.

(1) Silicon solar cells Silicon solar cells are divided into three types: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells. Monocrystalline silicon solar cells have the highest conversion efficiency and the most mature technology. The highest conversion efficiency in the laboratory is 23%, and the efficiency in scale production is 15%.

(2) Long-life battery with special process design and colloidal electrolyte guarantee.

(3) The battery is suitable for different environmental requirements, such as high altitude, high temperature, low temperature and other conditions.

Observe proper solar battery charging and discharging. It would also be best to connect your batteries to a trickle charger to maintain their charge, even if you do not intend to use them.

It would also help to overcharge your batteries periodically to enhance plate equalization. Plate sulfation can occur with insufficient charging. Because charge controllers suppress overcharging, you might want to turn these devices off as you overcharge your batteries.
