200 tube solar installation area

Introduction A solar installation of 200 tubes covers an area of ​​1.5 square meters for a 200w solar panel 1. The monocrystalline silicon solar cells used have a high conversion efficiency.

200 tube solar installation area

A 200 W solar panel requires 1.5 square meters once installed. 1. The monocrystalline silicon solar cells used have high conversion efficiency

2. The aluminum alloy frame used has strong resistance to mechanical impact.

3. Power tolerance range (guarantee that the output power is within the positive and negative tolerance range of -3 ~ +3%)

Generally, photovoltaic modules are marked with power, and the output of the energy is 200 W/The meaning of a module; the radiant power of solar radiation per unit area is called solar irradiation. The unit is watt/square meter. The module's power rating is tested under standard conditions, STC (standard). test condition), its standard test conditions. Yes: 1. Irradiance: 1000 W/m2; 2. Temperature: (25±1)℃; 3. Spectral characteristics: AM1.5 standard spectrum. does not take into account the factors ofequipment such as inverters, which are solar irradiation and temperature. The limiting value of solar irradiation is the solar constant, which is 1368 W/m2. After reaching the earth's surface, it is affected by weather conditions and other aspects. , and the maximum value is around 1200 W/m2. The module power temperature system About -0.39%/℃, as the module temperature decreases, the module power will increase Conclusion: A 200W module, without considering the equipment. loss, has a maximum output power of Pmax=1.2*(1 at a temperature of minus 30 degrees. -(25+30)(-0.0039)*200=1.2*1.1755*200= 282.65W The theoretical value should change depending on the weather conditions of the installation location. For example, there may be less electricity production in foggy weather. This depends on the gradual degradation of the component.
