Product Description:

Poly Solar panel, solar module, 250W, 255W

Grid-connected photovoltaic power generation system is to photovoltaic systemsconnected to the public grid, achieve grid. Grid-connected PV systems can be divided into large and centralized and decentralized power generation systems and power generation systems small, two systems not require energy storage devices. Currently PV grid integration in the form of the building is a typical case of power generation.

There're 7 major inspection procedures for Each piece solar panel during production : 

3 times EL testing to ensure panel without micro-break/invisible break(normal manufacturer only test 1 or 2 times); 

3 times appearance inspection to ensure panel without defect (normal manufacturer only inspect 1 or 2 times); 

1 time power testing, power inspection tolerance +/-0.1watt(normal manufacturer's power inspection tolerance is +/- 1-2watt), we ensure each panel has enough power output; 

besides the standard inspection, each production procedure will inspect the upwards procedure;

So we guarantee each piece of our panel has perfect appearance, positive power performance, and without quality hidden trouble.
