A class first Pyranometer was used to measure the direct solar irradiation and the obtained results were analyzed. Separate sensors were used to measure the relative humidity and the atmospheric temperature (RH/AT sensors). The measurements were conducted for the whole year of 2013. The author analyzed the collected solar data during one day, month, and year. The maximum, minimum, average, and accumulative solar irradiation (SR) were calculated and analyzed with connection to relative humidity

The author found that April was characterized by the average maximum solar irradiation (SR= 1112±1W/m 2 ), May had the maximum SR accumulation (13276552± 1W/m 2 ). The maximum average percentage relative humidity found in July (% RH = 97± 3%), while the minimum average % RH is in December (% RH = 25± 3%). In May, the maximum average atmospheric temperature was 36.0 ± 0.6 o C, while the average minimum was in January (AT= 19.1 ± 0.6 o C). The total accumulation of solar flux during the year 2013 is 222 ± 1MW/m 2 .
