How much power does monocrystalline silicon solar cell with square meter?

Before understanding this question, let's first learn the composition of monocrystalline silicon solar battery:

1. The toughened glass is used to protect the main body of the power generation (such as the battery), and the selection of light transmittance is required. First, the light transmittance must be high (generally over 91%); second, ultra white steel treatment.


2. EVA It is used to bond and fix toughened glass and main body of power generation (such as battery piece). The quality of transparent EVA material directly affects the service life of components. EVA exposed in the air is easy to age and turn yellow, which affects the light transmittance of components, thus affecting the power generation quality of components. In addition to the quality of EVA itself, the lamination process of component manufacturers also has a great impact, such as the adhesion of EVA is not up to standard, EVA and If the bonding strength of toughened glass and back plate is not enough, it will lead to early aging of EVA and affect the service life of components.

3. The main function of the battery is to generate electricity. The mainstream of the power generation market is crystalline silicon solar cells and thin-film solar cells, both of which have advantages and disadvantages. Crystalline silicon solar cells have relatively low equipment cost, high consumption and battery cost, and high photoelectric conversion efficiency. It is suitable to generate thin-film solar cells in outdoor sunlight, with relatively high equipment cost, low consumption and battery cost. The photoelectric conversion efficiency is more than half of that of crystalline silicon cells, but the weak light effect is very good, which can also generate electricity in ordinary light, Such as solar cells on calculators.

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


5. The function of the back plate is to seal, insulate and waterproof (generally TPT, TPE and other materials must be resistant to aging, and the component manufacturers guarantee 25 years, tempered glass and aluminum alloy are generally OK, the key is whether the back plate and silica gel can meet the requirements.

We know that the power generation efficiency of single-chip battery is very low. For example, the power of a 156 battery chip is only more than 3W, which is far from meeting our needs. Therefore, we connect multiple battery chips in series, which has reached the power, current and voltage required by us. The battery chips connected in series are called battery strings.

6. The aluminum alloy protects the laminated parts and plays a certain role of sealing and supporting.


7. The junction box protects the whole power generation system and acts as a current transfer station. If the short-circuit junction box of components automatically disconnects the short-circuit battery string, the most important thing to prevent the whole system from burning out is the selection of diodes. According to the types of battery chips in the components, the corresponding diodes are different.


8. Silica gel sealing function is used to seal the junction between components and aluminum alloy frame, components and junction box. Some companies use double-sided adhesive tape and foam to replace silica gel. Silica gel is widely used in China, with simple technology, convenience, easy operation and low cost.

If above information are well done, then there will be an answer:

How much power does a square meter monocrystalline silicon solar cell have?

A: about 160W
