The power generation capacity of the RV solar panel mainly depends on the size of the area.
1,the installation of solar modules,not simply installed casually can be,need to be based on your caravan electrical power to figure out how many watts of solar modules you need,and then based on how many days you probably need the power reserve to figure out how much battery you need,and then also to see how many calculated components can meet the needs of the roof area,whether the design is reasonable,and then improve.
2,take Iveco and the new generation for example,these two cars roof length and width are about 3.5*1.8m,basically can be installed between 500-2500 watts of solar modules,it is worth noting that more than 750 watts of solar panels can not be laid flat,because the roof is not so large area,but also need to be folded design.
3,for the installation of solar modules,it should be noted that:first of all,can not be stepped on;second,can not have a shadow cover;
4,if conditions allow,the side glass of the caravan can be specially customized all-glass components,so that not only does not affect the caravan lighting and can generate electricity,killing two birds with one stone,but the cost will be higher.
The following is a case study of installing solar power generation system for RVs.
Electricity load in the car.
1、A small refrigerator with 0.4 degrees of electricity per day;
2,600w rice cooker used twice a day,1 hour each time;
3,24-inch LED screen TV for two hours a day.1 LED small lights.Occasionally also use the computer,with the computer when you have to turn off the TV.
Based on these loads,the customer with a 750W solar power system:140W solar photovoltaic panels-2(taking into account the length and width of the roof and set);battery:2 12V100AH;inverter:750W frequency off-grid inverter;controller:30A12V.
Car enthusiasts who want to install can refer to the reference,according to their needs to calculate.
