320w quality approved high efficiency Polycrystalline solar Panel poly-crystalline for cheap sale
There're 7 major inspection procedures for Each piece solar panels during production :
3 times EL testing to ensure panel without micro-break/invisible break ;
3 times appearance inspection to ensure solar panel without defect ;
1 time solar power testing, solar power inspection tolerance +/3watt, we ensure each solar panel has enough solar power output; besides standard inspection, each production procedure will inspect the upwards procedure;
• So we guarantee each piece of our solar energy photovoltaic panel has perfect appearance, positive solar power performance, and without quality hidden trouble.
1. High conversion efficiency solar cells based on innovative photovoltaic technologies.
2. High stability 100% A grade photovoltaic cells with guaranteed +-3% solar power output tolerance,ensuring investment return.
3.Tempered front glass withstands high wind-pressure and snow load.
4. Easy to install.
• Advanced technology, professional manufacture, and excellent quality solar panels /solar energy /solar power .
