1. Toughened glass is used to protect the main body of power generation (such as the battery plate). The choice of light transmission is required. Second, ultra - white steel treatment.

2. EVA fixed toughened glass used for bonding and power main body (e.g., battery), the merits of the transparent EVA material directly affect the life of the components, exposed to the air in the EVA aging yellow, thus affect the light transmittance of the component, thus affect the quality of the component's power in addition to the quality of EVA itself, the component manufacturer of laminating process influence is very big, such as EVA adhesive degree is not up to standard, EVA and toughened glass, the back adhesive strength is not enough, will cause EVA early ageing, affecting the service life of components.

3. The main function of the battery is to generate electricity. The mainstream in the main market of power generation is crystalline silicon solar cells and thin film solar cells, both of which have advantages and disadvantages. The equipment cost of crystalline silicon solar cells is relatively low, the consumption and cost of the cells are very high, and the photoelectric conversion efficiency is also high. Solar cells are suitable for generating electricity in the outdoor sunlight. The equipment cost is relatively high, and the consumption and battery cost are very low. The photoelectric conversion efficiency is more than half of crystal silicon cells, but the weak light effect is very good.

4. The EVA functions as above, mainly binding the main body of power generation and the back plate.

5. The function of backplate is sealing, insulation and waterproof (TPT, TPE and other materials are generally used for anti-aging, and the component manufacturers have a warranty of 25 years.

We know that the efficiency of the single cell is very low, such as a piece of more than 156 cell power only 3 w, far can not meet our requirements, so we many piece battery piece together, already achieved we are looking for power, current, voltage, and be together piece of what we call the battery string.

6. The aluminum alloy protective layer pressing part plays a certain sealing and supporting role.

7. The junction box protects the whole power generation system and plays the role of current relay station. If the short circuit junction box of the component automatically disconnects the short circuit battery string, the most critical part of the whole system connection box is the choice of diode.

8. Silica gel sealing function is used to seal the junction of components and aluminum alloy frames, components and junction boxes. Some companies use double-sided rubber strips and foam to replace silica gel.
