Today, RV Explosion will talk to you about RV solar energy. As technology continues to develop and electrical equipment continues to increase, the electricity on RVs becomes increasingly insufficient. Our electronic equipment (especially car air conditioners) consumes a lot of power, and the battery power cannot meet the power consumption of RV players. Therefore, in order to meet the electricity needs of RV owners, RV manufacturers have installed solar panels on RVs as standard equipment (basically standard 200W). 1. So how much power do solar panels need to meet the electricity needs of car owners? Now I will provide you with a formula that you can calculate based on your actual requirements: If the rated power of the solar panel is 200W, under standard light intensity, the theoretical energy storage capacity of the panel per hour is 200W÷18V×12V ×1h=0.133kW·h, which is also known as 0.133 degrees, calculated if there is enough sunlight for 8 hours a day (summer). 0.133kW·h×8=1.064kW·h, which is approximately 1.1 degrees. After calculation, we can see that theoretically, a set of 200W solar panels can generate 1.1 kWh of electricity per day. If the light intensity and intermediate power loss are included, the charging efficiency is calculated as 77%, and the actual charging amount per day is It is 1.1×.0.75=0.825 kilowatt-hours of electricity. Generally speaking, the power of a 200AH battery is about 1.8 kWh. If you use a lot of electrical appliances, you can calculate how many watts of solar energy you need to install based on the actual energy consumption of the electrical appliances. 2. From the basic structure, solar panels are divided into three types: monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar panels. Each has its own characteristics: the conversion rate of monocrystalline silicon is 21%, and the conversion rate of polycrystalline silicon is 18%. , the conversion rate of amorphous silicon solar energy is 8-10%.

Each has its own characteristics: the conversion rate of monocrystalline silicon is 21%, and the conversion rate of polycrystalline silicon is 18%. , the conversion rate of amorphous silicon solar energy is 8-10%. Therefore, most car enthusiasts will choose monocrystalline silicon solar panel batteries. 3. What is the relationship between the temperature of solar panels and the efficiency of solar panels? (When the temperature exceeds 25°C, for every 1°C increase in temperature, the power generation of the solar panel decreases by 0.3%.) Therefore, the conversion rate of the hard board (supported by the bracket) is definitely higher than that of the soft board (directly attached to the car) under high temperature conditions. top) has a high conversion rate. 4. The better the packaging material of the solar panel (surface material, aluminum frame, back sheet, etc.), the better the heat dissipation, stress resistance, and corrosion resistance of the solar panel, and of course the higher the price. 5. The quality of solar panels is mainly judged from the following aspects: 1. Look at the surface and carefully check the surface of the tempered glass. Generally, in order to increase the production speed, small manufacturers often inadvertently drip silica gel onto the tempered glass. It may not be obvious. But if it is not clear, it will affect the normal operating efficiency of the battery panel. 2. Look at the battery pieces when they are spliced, and use broken splices. This method will cause the dragon chair to disconnect during use, affecting the overall efficiency. 3. Look at the back to see if there are bubbles or other phenomena on the back. 4. Check whether the silicone on the four sides of the silicone is even and whether it penetrates. 5. Look at the frame to see if the strength of the frame is even and whether the tightness is uneven. 6. Check the welding to see if there is any leakage. Check whether the battery sheets are regular. 7. Check whether the junction box is tight and can be freely rotated. 6. Solar panels also require maintenance if they are used for a long time. Clean the surface of the solar panel frequently and check whether there is any cover on the surface of the solar panel to prevent dust accumulation for a long time, which will affect the power generation efficiency. The service life of the solar panel itself is generally more than 15 years. The longer the time, the more obvious the power generation efficiency decreases. After reading today’s article, you should have a clear understanding of the choice of RV solar panels. You can choose the appropriate RV solar panel capacity according to your own electricity needs. I hope you like the RV solar panels. Explosive article.
