polysilicon solar cell
Product Details

Product features:

1. This polysilicon solar cell made of multiple crystals provides a noticeable sheet appearance and is usually blue. This type of silicon can be made with square ingots and is less resource intensive to produce. This product generates electricity when exposed to light. Sunny weather and a cool breeze will produce the most energy.

2. Compared with single crystal, our polysilicon solar cell has less amount of waste silicon. Polycrystalline solar panels tend to be slightly less heat resistant than monocrystalline solar panels. This technically means that their performance at high temperatures is slightly inferior to that of monocrystalline solar panels. Heat can affect the performance of solar panels and shorten their life. However, this impact is small and most homeowners do not need to consider it.
