The solar panels are made as like the blades of blinds, and the green energy LEDs designed on panels?? back-lighted side. Such assembled photovoltaic modules can be placed horizontally (treated as a green arbor of electricity-free auto panel cleaning, solar-charging and space-using can hold concurrently and have) or vertically (treated as a photosensitive blind, the indoor temperature can be reduced with the effect of energy conservation and carbon reduction), significantly overthrow traditional construction and is more effective, also overcome the shortcomings of occupying the space & ugliness on nowaday solar system. Especially, the solar panels also are directly treated as sun-tracking sensors by originally applying the program-controlled mechanical theory to reduce the additional components and increase benefits. DIY structure facilitating the constructing of photovoltaic system is a revolution in the popularization of green photonics applications.
