HDT double glasses solar module has been striving to achieve the lowest cost per kilowatt hour among the same kind of products. The photovoltaic power station made of HDT double glasses solar module requires less land area, support brackets, cables and labor for each unit capacity. The power generation of HDT double glasses solar module is more than 10% higher than that of traditional crystalline silicon solar modules, therefore the ROI of PV power plant made of HDT solar module is more than 20% higher than traditional technologies.
