Question
I MEASURE THE SUNSHINE DURATION AND I MEASURE 12 HOURS AND 58 MINS DURATION OF SUNSHINE. (you can use the formulas above to answer the following questions thank you.)
w – sunset hour angle (radians) p – latitude (radians) 8 – solar declination (radians) The parameter d is given by, = 1 + 0.033 cos cos 365 Guide Questions: I MEASURE THE SUNSHINE DURATION AND I MEASURE 12 HOURS AND 58 MINS DURATION OF SUNSHINE. (you can use the formulas above to answer the following questions thank you.) Based on your 1 day solar radiation measurement, how much energy would you save for that day if you were able to harness 80% of the solar radiation? • Project the energy savings in your household for a year if you use solar power as the source of electricity.

To conduct the experiment, follow the following procedures: 3. Measure the sunshine duration for a particular day, expressed it in hours. 4. Estimate the incident solar radiation using the following equations: )R. R = 25 + 0.5- Where, R solar or shortwave radiation (MJ/m²-day) n – sunshine duration (hour) N- maximum possible daylight (hour) R - extraterrestrial radiation (MJ/m²-day) a The value of N is estimated using, N = (») %3D Where w is the sunset hour angle (radians) and estimated using, W = (- tan tan p tan tan 8 ) Where, p is the latitude of the measurement location (radians) and the value of solar declination (radians), 8, is given by, 8 = 0. 409 sin sin 365/ - 1. 39) The J is the date ranges from 1 to 365 or 366 (for leap year). For a measurement taken in January 1, J = 1 and if measurement is taken in December 31, J= 365 (J = 366 for leap year). Extraterrestrial solar radiation is estimated by, 1440 -G_d(w_sin sin p sin sin 8 r s R = cos cos p cOs cos 8 sin sin w a sc Where, R – extraterrestrial solar radiation (MJ/m²-day) G - solar constant (0.0820 MJ/m²-min) d - inverse relative distance Earth-Sun
