Solar panels, these photovoltaic panels are actually like batteries one by one, but they are charged by the sun, so as long as there is sunlight, it will generate electricity at any time.
The frame of the photovoltaic panel uses an aluminum alloy frame, which not only ensures its hardness, but also ensures that it will not rust and rot, and is relatively lighter in weight, ensuring its longer service life. On the surface of the photovoltaic panel is a tempered glass with extremely high light transmittance. The more transparent the glass, the higher the power generation efficiency, so the photovoltaic panel has high requirements for the light transmittance of the tempered glass. The main cell for power generation is closely adhered to the tempered glass. Now the mainstream photovoltaic cells include monocrystalline silicon, polycrystalline silicon, and thin film. I don’t know about the thin film. The efficiency is good, but the high cost has caused him not to be widely promoted. The power generation efficiency of polycrystalline silicon is not as good as that of monocrystalline silicon, but the material cost is relatively low, which is worse than monocrystalline silicon in terms of cost performance, so it has been vigorously developed. Photovoltaic panels.
The back of the battery is the back plate, which plays the role of sealing and protecting the battery. The use of waterproof silicone to seal the component with the aluminum alloy frame can effectively play the role of waterproof and air isolation, so that the battery is durable and will not age. There is a junction box in the middle and upper part of the backplane. It is the two wires separated from the junction box that continuously transport the power from the battery.
