    How do solar panels collect sunlight?

Each solar panel contains so-called cells, also known as photovoltaic cells. These cells collect light and convert it into solar energy. When the sun shines on the solar panel, the photovoltaic cell will generate (DC) direct current. This is where the inverter works. Inverters convert solar energy into usable electrical energy.

DC power cannot supply power for your equipment alone, so you need solar inverters. The solar inverter converts the direct current generated by the solar panel into alternating current. Stored in the battery or incorporated into the mains. Electricity from solar panels. Power supplies your home and your appliances. Its working principle is the same as that of traditional electricity.

Sometimes you may notice that your solar panel does not generate enough energy to meet all your power needs. Of course, you need not worry when you are still connected to the traditional power company through the grid. Therefore, what you need to do is to draw more energy from the solar energy when you need it.

Advantages of mono half cell panels

1. Reduce heating and temperature loss. As the internal current and internal loss are reduced, the working temperature of the module and junction box decreases, and the probability of hot spot and the risk of damage to the entire module are greatly reduced. Under the outdoor working condition of the module, the temperature of the half module is about 1.6 ℃ lower than that of the conventional whole module.

2. Reduce shielding loss. With its special parallel string structure, the half piece module can improve the utilization rate of supports and land while reducing the power generation loss caused by shadow shielding.

3. Improve packaging efficiency. The packaging loss of conventional components is generally greater than 1%, while that of half chip components is generally about 0.2%. Therefore, the half chip module makes use of the low current characteristics to effectively improve the packaging efficiency of the module.

Development trend

With the increasing pressure on power station investors to access the Internet at parity, the demand for electricity cost per kilowatt hour is getting higher and higher. Compared with conventional components, the cost of half chip components mainly increases in the manufacturing process, including battery slicing, auxiliary materials and labor costs, equipment depreciation costs, etc. However, the power of the half chip module can be improved by 5W-10W or even higher than that of the same version of the module. As the component price continues to decline, the overall system cost of the half chip component is reduced.
