                              Five skills choose the best module supplier for your system

1.Mainstream Brands

If suppliers of the module mainstream of the industry brand, the quality assurance and after-sales service of the big brand are guaranteed

2. The Welding Process.

For good quality panel,there is no leakage welding area between the cells in series.

3.Check The Back Surface Process Of Module.

There is no unevenness , or bubbles, folds, etc. It is not difficult to find bubbles and folds, and it can be seen easily

4. The Border Frame.

The frame is strictly rectangle, and the error can hardly be seen

5. Module Conversion Efficiencies

High conversion rate is the guarantee of the plant income. The conversion efficiency surface needs to be compared to the parameters. With 60 pcs of polycrystalline silicon PV modules which were commonly used: 
250W conversion efficiency of PV modules is 15.4%; 

255W conversion efficiency of PV modules is 15.7%; 

260W conversion efficiency of PV modules is 16%; 

265W conversion efficiency of PV modules is 16.3%; 

270W conversion efficiency of PV modules is 16.6%;

If a company advertise a photovoltaic panel brand polysilicon 60 cells, conversion rate reached more than 20%, Ha Ha ! It must be a fake!
