We all know about solar energy and of course how important it is to us. Moreover, the application of solar energy is becoming more and more widespread at present. Solar DC Freezer is one of them. Nevertheless, solar energy still has certain inconveniences for us.
The dispersion of solar energy. Although the total amount of solar radiation reaching the surface of the earth is large, the energy flow density is very low. On average, near the Tropic of Cancer, when the weather is clear in summer, the irradiance of solar radiation is the largest at noon, and the solar energy received on an area of 1 square meter perpendicular to the direction of sunlight is about 1,000W on average; The average day and night throughout the year is only about 200W. In winter, it is only half, and cloudy days are generally only about 1/5. This kind of energy flow density is very low. Therefore, when using solar energy, to obtain a certain conversion power, a set of collection and conversion equipment with a relatively large area is often required, and the cost is relatively high.
Therefore, China freezer still needs some time to make corresponding improvements.
