Solar panelsThe current price is 255-270 yuan each.
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 household 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°, the power generation efficiency is the highest. When the temperature exceeds 25°C, the electricity production of the solar panels will be reduced by 0.3% for every 1°C increase in temperature. When the glassIf used as a packaging surface, the temperature of the battery will increase significantly due to the light transmission and thermal conductivity properties of the glass, which will affect the power 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 power of Wp solar cells is under standard sunlight conditions, that is: standard 101 defined by the European Commission, ray intensity1000 W/m2, air. AM1.5 grade, the output power of solar cell when the battery temperature is 25℃.
