How to distinguish solar panels

Classification of solar panelsAccording to different materials, solar panels can be divided into polycrystalline silicon solar panels, monocrystalline silicon solar panels, amorphous silicon solar panels, flexible solar panels, etc.

1. Polycrystalline silicon solar panels

Polycrystalline silicon solar panels are currently the most widely used model and are relatively cheap. Polycrystalline silicon solar panels are made up of multiple fragmented silicon crystals. They are blue or dark blue in color and have low power but high photoelectric conversion efficiency.

2. Monocrystalline silicon solar panels

Monocrystalline silicon solar panels are made of monocrystalline silicon crystals and are black in color and beautiful in appearance. The production cost is high and the price is relatively high, but the photoelectric conversion efficiency is high and the power is high.

3. Amorphous silicon solar panels

Amorphous silicon solar panels are made of amorphous silicon thin films, which are softer and lighter, but their actual service life is not as good as crystalline silicon panels. Amorphous silicon solar panels are brown in color, have lower power but are relatively cheap.

4. Flexible solar panels

Flexible solar panels are mainly made of polymer films and are black in color. They can be bent, folded, lightweight and easy to carry. They are suitable for special occasions such as outdoor travel, camping, and boats.

2. How to distinguish solar panels

When purchasing solar panels, you need to choose different types of solar panels based on your needs.

1. Performance indicators

The main performance indicators of solar panels include photoelectric conversion efficiency, power, voltage, current, etc. Monocrystalline silicon solar panels have the highest photoelectric conversion efficiency and power under the same area.

2. Appearance characteristics

The surface of the solar panel is covered with a layer of polymer to prevent water vapor from penetrating and affecting the cells. Pay attention to check whether there are obvious potholes or uneven places, which may affect the performance of the solar panel.

3. PriceThe price of solar panels is also an important factor to pay attention to when purchasing. The price of polycrystalline silicon solar panels is relatively low, but the photoelectric conversion efficiency is relatively low; the price of monocrystalline silicon solar panels is relatively high, but the photoelectric conversion efficiency and power are high.

3. Purchase suggestions

1. Choose different types of solar panels according to your own needs. You can consult professionals or online certified solar panel specialty stores before purchasing.

2. When purchasing, you need to pay attention to factors such as the performance indicators, appearance characteristics, and price of solar panels, compare solar panels of different brands and models, and choose products with higher cost performance.

3. If you need to use solar panels for a long time, it is recommended to choose products of good quality to avoid frequent replacement and repair, which may cause unnecessary losses.

In short, when purchasing solar panels, you need to choose the appropriate brand and model, and choose different solar panels according to your own needs, so that you can better utilize solar energy and contribute to environmental protection and energy conservation.
