Solar panel for home is the core part of the solar power generation system. The function of the solar panel is to convert the light energy of the sun into electrical energy, and then output the direct current and store it in the battery. Solar panels are one of the most important components in household solar power generation, and their conversion rate and service life are important factors that determine whether solar cells have use value.

Raw material characteristics

Cell

Adopt high-efficiency (above 16.5%) monocrystalline silicon solar sheet packaging to ensure sufficient solar panel power generation.

grass

Using low-iron tempered suede glass (also known as white glass), the thickness is 3.2mm, and the light transmittance in the wavelength range of solar cell spectral response (320-1100nm) is more than 91%. High reflectivity. At the same time, the glass can withstand the radiation of solar ultraviolet rays, and the light transmittance does not decrease.

EVA

The high-quality EVA film layer with a thickness of 0.78mm added with anti-ultraviolet agent, antioxidant and curing agent is used as the sealing agent of solar cells and the connecting agent between glass and TPT. Has high transmittance and anti-aging ability.

TPT

The back cover of the solar cell—the fluoroplastic film is white and reflects sunlight, so the efficiency of the module is slightly improved, and because of its high infrared emissivity, it can also reduce the operating temperature of the module, which is also beneficial to the Improve the efficiency of components. Of course, the fluoroplastic film first has the basic requirements of aging resistance, corrosion resistance, and airtightness required by solar cell packaging materials.

frame

The aluminum alloy frame used has high strength and strong resistance to mechanical impact. It is also the most valuable part of home solar power generation. Its function is to convert the radiation capacity of the sun into electrical energy, or send it to the battery for storage, or push the load to work.

Application classification

Off-grid power generation system

It is mainly composed of solar cell components, controllers, and batteries. To supply power to the AC load, an AC inverter needs to be configured.

Grid-connected power generation system

That is, the direct current generated by the solar module is converted into alternating current that meets the requirements of the mains grid through the grid-connected inverter, and then directly connected to the public grid. The grid-connected power generation system has centralized large-scale grid-connected power stations, which are generally national-level power stations.

Design Principles

The design of the solar power supply system requires the cooperation between the user and a professional solar technology company. First, the user needs to provide the exact usage requirements, including:

1. The electricity voltage and power to be solved;

2. Daily working hours, continuous rainy days guarantee time;

3. Whether there is a backup mains power supply;

4. The system uses regional and climate data;

5. If it is to supply power to the equipment, it is best to provide the name, manual or technical parameters of the equipment.

Due to the high one-time input cost of solar power supply, the design should be based on the principle of economy and practicality, and the investment should be reduced as much as possible. failure rate.
