Sunnypex SOLAR PANEL (All Weather ) Poly 100Watts -18Volt +Free Solar Contoller ,3 Pieces 12v LED Bulbs

Advanced encapsulation material with multi-layered sheet lamination to enhance cell performance and provide a long service life.

EL tested solar modules; no hot-spot heating guaranteed.

Bypass diodes minimize power drop caused by shade and ensure excellent performance in low-light environments.

TPT back sheet ensures smooth performance over a long period of time.

The process used to make polycrystalline silicon is simpler and cost less. The amount of waste silicon is less compared to monocrystalline.

Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. Polycrystalline solar panels will tend to have a higher temperature co-efficient than solar modules made with mono cells. This means that as heat increased output for this type of cell will fall less. However, in practice these differences are very minor.
