Does Uv Affect Solar Panels

Sunlight energy that reaches the ground is around 4 ultraviolet 43 visible light and 53 infrared.

Does uv affect solar panels.

Whilst the effect is minor it can still have an impact on levels of uv reaching the earth s surface. Solar panels mostly convert visible light into electrical energy and they also can make use of almost half the infrared energy. The systems with water cooling do not expose solar panels to such a sudden temperature shock like you hosing them down would. Based on the relationship from the data above a uv index of 1 indicates 85 6w m 2.

As you can see silicon solar panels can manage to use some of the ultraviolet portion of sunlight on the far left. Note that my solar panel is only 4 4 x5 4 or 0 01533m 2. It has been found that uv increases by up to 4 for every 300m increase in altitude. 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.

Sunlight should hit solar panels as directly as possible. Multiplying the solar energy times the area of my solar panel yields only 1 31w of power. Small particles suspended in the air can scatter solar uv. Hence the ideal angle for a solar panel is perpendicular to incoming sunlight.

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

But solar panels only use a small portion of ultraviolet. In these conditions solar panels generate more power than when the sun is incident at indirect angles.
