Usage and Applications of Poly Cells:
Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current;our solar cells have passed IEC Certification. With high quality and stable quality. Our Cells can greatly improve the performance of Solar Modules.
Packaging & Delivery of Poly Cells:
Carton Box Package and Deliver by air. It should be noticed that it should be avoid water, sunshine and moist.
