Does Uv Affect Solar Panels

But solar panels only use a small portion of ultraviolet.

Does uv affect solar panels.

Sunlight energy that reaches the ground is around 4 ultraviolet 43 visible light and 53 infrared. Solar panels mostly convert visible light into electrical energy and they also can make use of almost half the infrared energy. Note that my solar panel is only 4 4 x5 4 or 0 01533m 2. In these conditions solar panels generate more power than when the sun is incident at indirect angles.

Small particles suspended in the air can scatter solar uv. Multiplying the solar energy times the area of my solar panel yields only 1 31w of power. It has been found that uv increases by up to 4 for every 300m increase in altitude. Whilst the effect is minor it can still have an impact on levels of uv reaching the earth s surface.

Based on the relationship from the data above a uv index of 1 indicates 85 6w m 2. Sunlight is at its greatest intensity when it is incident directly upon a surface. Sunlight should hit solar panels as directly as possible. Answered july 11 2020.

The amount increases as it becomes visible light and panels go on to produce most of their electricity from visible light. Id like to work out the correlation between the above solar rad readings to solar output from panels. Direct and diffuse uv. When i first had this idea in january the uv index would never have exceeded a value of 1 even at noon.

28 1417 0 w m 13 4 uv sometimes solor radiation is higher than uv if plotted on a graph then some times the opposite occurs. With that information i can determine the amount of solar energy available at any time by simply checking the weather.
