Product Description

Product Description

 

       If you are considering installing bifacial solar panels for your home, please consider all these issues before buying. If you only check one of them, the bifacial solar panel installation will work for you. If you choose multiple options, then bifacial is your best choice!

A. Are you thinking of installing a solar system on the roof?

B. Do you want to build a sun room to enjoy the warm sun in winter?
C. Do you want to build an awning in the yard?

D. My roof happens to be white or light-colored, I would also like to paint these new colors?

 

        Since the double glass bifacial solar panel occupies less space than the conventional single-sided, it does not need to pass more
land to obtain greater power generation, but it does require a light-colored surface to obtain the best performance.
