These expressions include the original Angstrom-Prescott regression function (linear), quadratic function, third-order function, single-term exponential function, power function SOLAR RADIATION CHAMBERS. The exposure to sunlight can damage your product, decrease its performance and shorten its life; so it is crucial to understand in advance which would be the reaction to solar, humidity and temperature variation.

Megajoules is energy and Watts is power so there is no direct conversion between them. noticed that the average radiation is not very high this is only due to zero radiation values during night time which affects the average values, but the maximum values below shows that the radiation levels can reach high values throughout the year. The maximum recorded radiation value during the three years was 1289 W/m2 in May 2013.
