Measurement of Solar Constant using Simple Route

The radiation emitted by the sun and reaching the earth comprises long electromagnetic waves. The solar constant has been measured using glass beaker equipment for six days in the month of February 2020. According to our results, the solar constant value indicates that the value is not fixed but varies with time and these variations happened due to the solar activities such as weather, climates, etc. In the present article, we discussed the locally fabricated low-cost device of glass beaker which is used to evaluate the solar constant and the calculated average black ink added water value is 1387.19 W/m2 at the ground surface.
