Solar panel also call solar cell, or photovoltaic cell , is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
Solar Panel can power electricity for home ,office, factory ,hotel as whole set of solar system as bellows pictures:

POLYCRYSTALLINE SOLAR PANEL
The first solar panels based on polycrystalline silicon, which also is known as polysilicon (p-Si) and multi-crystalline silicon (mc-Si), were introduced to the market in 1981. Unlike monocrystalline-based solar panels, polycrystalline solar panels do not require the Czochralski process. Raw silicon is melted and poured into a square mold, which is cooled and cut into perfectly square wafers.
HUAMI solar, we commit ourselves to R&D, manufacture and technical innovation on pv modules and solar power system. To provide high quality products with various specifications to customers is always our pursuit.
/ Product Characteristics
1. Use high quality solar cells to advanced encapsulation.
2.Adopt high transparent low-iron tempered glass, high quality anti-UV EVA and back sheet.
3. With multi-ply performance testing for each module, to ensure the product quality and output performance.
4. Using anodization aluminum frame with anticorrosion, to ensure solar module working under extremely and badly outdoors environment.
/ Product Advantages
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. This technically means that they perform slightly worse than monocrystalline 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.
