Some solar cells

It's been a long time to update blog. 

Not for busy work, but for I was not able to compose words. Like before, some pictures for introducing our products.

156*153 mm,polycrystalline, 3 bus-bars

Duel continuous 3-bus-bar is optional for you, big or small panels. The power is over 4.2 Watt(efficiency 17.6%+), very near a standard cell's. Also, you can cut it to small pieces for a very small epoxy resin solar panel.

156*156 mm, polycrystalline, 4 BBs

More BBs, more efficiency. This opinion is popular in our circle. Over 18% efficiency is very high in polycrystalline, approximates to monocrystalline's. But the price is lower much than monocrystalline.

Some Parameters of Solar Cells

Different plants supply different solar cells. The differences are size, surface, efficiency and other parameters. 
Here are some tables show different products.

About Efficiency in Photovoltaics Nov. 22, 2015

Efficiency is a figure without unit, usually the figure shows in percentage(%).  Sunlight supplies us radiation intensity of 1000W/㎡， but the solar cell can not change it into electricity 100%. That's an important figure in photovoltaics industry--efficiency of conversion.

We test it in STC: 25℃, radiation intensity 1000W/㎡, and AM1.5.  The equation is:

Efficiency(%)=output power/input power

In other words, if the efficiency of solar cell is 18%, in STC, the solar module can convert 180W power per square meter.
