What are Poly Solar Panels?
The first solar panels based on polycrystalline silicon, which also is known as poly silicon (p-Si) and multi-crystalline silicon (mc-Si), were introduced to the market in 1981. Unlike mono crystalline-based solar panels, polycrystalline solar panels do not require the Czochralski process. The amount of waste silicon is less compared to mono crystalline. Poly crystalline solar panels tend to have slightly lower heat tolerance than mono crystalline solar panels. This technically means that they perform slightly worse than mono crystalline solar panels in high temperatures. Heat can affect the performance of solar panels and shorten their lifespans. However, this effect is minor, and most homeowners do not need to take it into account. The efficiency of polycrystalline-based solar panels is typically 13-16%
