The advantages of solar cold room and the introduction of solar panels

Solar photovoltaic power generation is currently the most promising new energy utilization technology. Solar cold room uses this technology and renewable solar energy resources to provide a sustainable and reliable solution for storage and preservation needs. In recent years, more and more solar cold rooms have been applied on a large scale. In this article, we will take a look at the advantages of solar cold storage, focus on the relevant information of solar panels, and the reasons for choosing solar cold room.

Advantages of solar cold room

1. Environmentally friendly. As a renewable energy source, using solar energy for power supply can reduce dependence on traditional energy sources, reduce consumption of fossil fuels, and reduce greenhouse gas emissions.

2. Cost savings in the long run. Solar energy is a free resource, and once a solar cold storage system is established, the operating costs are relatively low. Although the initial investment for installing a solar system is high, in the long run, solar cold storage can significantly reduce energy consumption and operating costs, bringing considerable energy-saving benefits and cost savings.

3. It can be used flexibly and is not limited by the geographical distribution of resources. The solar system is independently powered and does not need to rely on the grid, so it can be used in remote areas, where the grid supply is unstable or where there is no grid supply, so as to ensure a stable cooling effect, effectively reduce the loss rate of agricultural products, and improve commercial profitability. .

4. Intelligent management. The solar cold storage can monitor and adjust the temperature, humidity and other environmental parameters of the cold storage through the remote monitoring and control system to ensure the safety and quality of the stored items.

5. High space utilization efficiency. The cold storage has a large area of idle roof, and installing solar panels on it improves the space utilization rate, and can reuse the vast cold room space.

Introduction of solar panels

A solar panel is an assembly composed of multiple solar cells, and is the core part of a solar power generation system, which directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect.

The solar cell is installed on the front of the panel, and the type of the cell can be judged according to different colors and appearances, including polycrystalline silicon, monocrystalline silicon, amorphous silicon, etc. Monocrystalline silicon solar panels are the earliest solar panels, so they have the most developed and mature technology. t is made of about 40 single crystals of silicon. Currently, there are 420W and 560W types of monocrystalline silicon solar panels available for solar cold room. At least eight monocrystalline silicon solar panels can form a matrix for use. Polycrystalline solar panels, which have only been developed in recent years, are made from fragments of silicon crystals that have been melted together.

Because the purity of silicon in monocrystalline silicon is higher, the average conversion efficiency of monocrystalline silicon solar panels can reach 22%, which is higher than the conversion efficiency of polycrystalline silicon at 18%, and the price will be relatively expensive. Amorphous silicon solar cells are rarely used due to their low photoelectric conversion efficiency and instability. From the appearance, the color of monocrystalline silicon solar cells is dark blue close to black, while the color of polycrystalline silicon solar cells is blue.

Reasons for choosing solar cold room

The emergence and development of solar cold room not only greatly reduces energy consumption, but also improves the flexibility and independence of cold room. It improves economic and environmental benefits. In addition, solar panels can also block direct sunlight, rain and snow, prolong the service life of the cold room roof, and reduce equipment loss. In a cool environment under the photovoltaic panels, the cold storage is more energy-efficient.

Cold room is one of the equipment with high power consumption rate in the field of commercial buildings, so more energy-saving and cost-effective cold room solutions are extremely important. I hope you can improve your understanding of solar cold room through this article, and choose a more suitable cold room solution!
