With the rapid development of social economy, environmental problems have become more and more prominent, global climate warming has intensified, and extremely hot weather occurs frequently. Unfortunately, some areas are experiencing scorching heat due to high electricity costs or even lack of electricity that prevents them from using refrigeration equipment. With the development of science and technology, more low-cost new energy sources have been developed, such as solar energy. At present, solar energy development and application technology is becoming mature, and more and more households and businesses are using solar energy systems. Before purchasing a solar system, many users will wonder how large a solar panel they should choose. This article will briefly popularize relevant knowledge. What factors should we consider when choosing the size of solar panels?

First, we need to determine our electricity needs. How much electricity you need to use each day will determine how much solar panels you need to generate electricity. Different users have different electricity needs, which will affect the scale of solar panels we purchase. Generally speaking, customers with large electricity demand order more solar panels. For example, the order scale of solar system for commercial use is much larger than that of solar system for residential use.

Secondly, we need to determine the efficiency of the solar panels. Because the efficiency of a solar panel affects its output power. The formula for calculating solar panel efficiency = solar panel area * 0.1 * conversion rate. Generally speaking, the efficiency of solar panels is between 15% and 20%. That is to say, each square meter of solar panels can generate 150-200 watts of electricity.However, the solar panels developed by Anern have an efficiency of 22%-24%, which is higher than the general solar panels on the market.

Furthermore, we need to consider the installation location of the solar panels. The installation position and angle of solar panels will affect their output power. For example, if the same solar panel is installed near the equator and near the regression line, its output efficiency is completely different. Because the direct sunlight lasts longer near the equator, its output efficiency will be higher. In addition, we also need to consider the location of the direct sun point. Wherever the direct sun shines on us, the installed solar panels should face in that direction. For example, when we are north of the Tropic of Cancer, the direct sun point is to our south all year round, so when we install solar panels, they must face south. This can make full use of solar radiation and improve the output efficiency of solar panels.

Finally, we have to consider the cost of using solar panels. Solar panels require regular maintenance during use, such as cleaning and inspection, so as to maintain a high conversion efficiency. The larger the scale of the solar panel, the greater the subsequent maintenance costs. Therefore, when choosing the size of solar panels, it is necessary to consider both demand and cost.
