Factors affecting the price of home solar panels:
1. The Impact of Weight on Price
When the camper leaves the factory, the camper manufacturer will limit the weight of the camper to comply with state policy. The weight of the camper, various appliances and daily necessities take up a lot of weight. Lighter is better while still maintaining the efficiency of the solar panel, and the lighter the solar panel, the higher the price.
2. The impact of temperature on price
When the temperature of the solar panel is 25°C and the light is 90°, it generates electricity. When it is most efficient. When the temperaturetemperature exceeds 25°C, the electricity production of solar panels will be reduced by 0.3% for each 1°C increase in temperature. When glass is used as a packaging surface, the temperature of the battery will increase significantly due to the light transmission and thermal conductivity properties of glass, which will affect electricity generation.

Tips for purchasing home solar panels: < p>1. Solar cell packaging form selection
For low-power solar lawn lights less than 1W, if there are no excessive life requirements, the solar cell packaging form Glue packaging can be used. There are regulations on shelf life. . For solar lamps, it is recommended to use plastic packaging.
2. Selection of solar cell power
The output powerie Wp solar cells are in standard sunlight conditions, that is to say: standard 101 defined by the European Commission, radiation intensity 1000 W/m2, air. AM1.5 grade, the output power of solar cell when the battery temperature is 25℃.
