new 310W solar panel price solar products 2012

1.0~+3% power tolerance. 2.TUV,UL,MCS,CE,ROHS,Golden Sun certified 3.Underwriting of 25years output power warranty by The Peo We adopt high transparent low iron, tempered glass and self-supporting solar cells in order to improve conversion efficiency on our solar modules and maximize the power generation in an unit area, so that reduced the cost.There will be precise electrical performance test on each panel, output power tolerance will be within 0~+3%With anodic oxidation aluminum frame encapsulated,our modules have already been approved by UL certification authority on the test of 5400Pa mechanical loads.We have got TUV,UL,MCS,CE,ROHS and Golden Sun certificate for our products, ISO9001 certificate for quality management system as well.
