When we travel, we will carry a lot of electronic equipment in the car, resulting in more and more places using electricity. Insufficient power has become a pain point for many RV players. In order to solve this problem, AJPOWER perfectly installed the solar power generation system on the RV, which also attracted the attention of many potential buyers of the RV.

Working principle of solar cell system

            The direct output voltage of solar energy is generally 12V.24V 48V。 If you want to supply power to 220V electrical appliances, you need to convert the DC power generated by the solar power generation system into AC power through the inverter.

How much electricity can the solar panel charge in a day?

         If a solar panel with a rated power of 300W has insufficient standard light intensity and battery power, theoretically, the power storage in an hour is 300W ÷ 18V × 12V × 1h=0.2kW · h, that is, the electricity quantity of 0.2kWh, which is often said to be calculated according to the average sunshine of 6 hours per day. Then 0.2kW · h × 6=1.2kW · h, about 1.2kWh.

        After calculation, theoretically, a group of 300W solar panels can produce 1.2 kilowatt hours of electricity a day. If the intermediate loss of light intensity and electric quantity is included, the charging efficiency is calculated by 80%, and the electric quantity charged for 6 hours in a day is about 1 kilowatt hour.

         So what kind of electrical appliances can be used to make a self-propelled C-type RV run normally within 6 meters? The total lighting equipment of the RV is temporarily calculated as 100W. The total power of 80W refrigerator, 80W LCD TV, 30W laptop and mobile phone is about 300W, which means that these electrical appliances can work together for 1.2 ÷ 0.3=4 hours.

        Although these are only part of the electric appliances of RV, there are many places where RV needs electricity, so a good way to solve the problem of RV electricity is very important. Solar energy may not completely solve the problem of electricity, but it is indeed the most ideal auxiliary equipment for RV electricity at present.

           Installing solar modules is not easy. You need to calculate how many watts of solar cell modules you need according to the power consumption of your RV electrical appliances, and then calculate how many batteries you need according to how many days of power reserves you need. Then you need to see whether the calculated components can meet the requirements of the roof area and whether the design is reasonable.

          Attention shall be paid to the installation of solar modules: first, do not step on them; Second, you can't cover it.

          From a practical point of view, it is a good choice to install a set of solar photovoltaic panels on the RV and use solar power to power the RV. If you use your RV for a long time and often travel outdoors, solar energy becomes more important. AJPOWER can provide more appropriate RV energy solutions according to your actual situation.
