1 The photogenerated current increases linearly with light intensity, but the voltage decreases due to temperature. But in general, there is no problem if the battery panel is directly proportional to the light intensity. between 200W/㎡---1500W/㎡. The light intensity can be seen from the I-V curve below. I don't seem to have heard that there is an upper limit for the light intensity you can accept. understand it as mentioned above. In this range, bigger is better. It is not clear if the light intensity exceeds 1500 W/㎡, but where on earth the light intensity will exceed 1500 W/㎡. However, if the temperature is too high, the battery board will be damaged. ?2 The spectral range accepted by the battery panel is based on the spectral response range of the battery sheet. The spectral response range of the battery sheet is also attached below. It is aboutsensibly of all colored light and part of near-infrared light. 3? A significant increase in light intensity will increase the power output of the panel will not increase efficiency, which is fixed. It seems worth posting a photo, but I won't post the one on the spectral response, which is almost all visible light and some near-infrared light. I would like to add that what we call the light intensity at 30° north. latitude is meaningless. The climate of each place. The conditions are different. The average radiation intensity of each location in the world can be found on NASA.
Solar street light is a kind of lighting equipment that uses solar energy to generate electricity. Its lighting requirements mainly include the following aspects.
First of all, the lighting required for solar street lightsres is sufficient sunshine. Solar street lights convert sunlight into electrical energy using solar panels. Therefore, there must be enough sunlight hitting the panels to ensure that the solar panels can fully produce electricity. Generally speaking, solar street lights need at least 6-8 hours of sunlight during the day to provide enough power for nighttime lighting.
Second, solar street lights have stable lighting requirements. Since solar street lights rely on solar energy to generate electricity, they have higher requirements for light stability. If the lighting is unstable, the power generation efficiency of the solar panel will be affected, thereby affecting the lighting effect of the solar street light. Therefore, when choosing a location for installing lampadaSolar ires, you should consider the stability of light and avoid obstacles such as high-rise buildings or trees to block sunlight.
In addition, the lighting requirements of solar street lights also include light intensity and uniformity. Light intensity directly affects the power generation efficiency of solar panels, so it is necessary to ensure that the light intensity is high enough. At the same time, solar street lights should also ensure light uniformity, that is, the light intensity of the entire street lighting area should be relatively uniform to avoid uneven light and darkness .
Finally, the lighting requirements of solar street lights also include the lighting duration. Solar street lights must provide lighting at night, so the duration of the light must be long enough. FromGenerally speaking, solar street lights should be able to continuously illuminate for at least 8-10 hours at night to meet people's lighting needs.
To summarize, the lighting requirements of solar street lights mainly include sufficient sunshine, stable lighting, light intensity and uniformity, and light duration. Only by meeting these requirements can solar street lights operate properly and provide people with safe and efficient lighting services.
