Is a Black Solar Radiation Shield Better Than White?
The color of your radiation shield will not change the results, so you don’t have to worry about dust, sand, or dirt building up on it.
What effect does dirt buildup have on the sun-induced temperature error (solar heating) of your radiation shield? What is the resulting temperature error? When you have a solar radiation sensor, you might be wondering how to account for the potential errors.
You might be surprised to learn that if the wind speed reaches more than 2.3 miles per hour, there will not be much in the way of errors. When a test got done, the mean measurement error was only about 0.3 degrees Celsius for a black solar radiation shield. The maximum deviation was only around 0.43 degrees Celsius.
So even if your application has a lot of dust, dirt, or sand, you can rest assured that this is not even close to having heavy black paint. This means you can safely assume that even if your solar radiation device is extremely dirty, you do not need to worry about it giving you an inaccurate answer.
