a) Describe the following (i) Extra-terrestrial radiation (ii) Irradiation (iii) Diffuse radiation (iv) Solar declination angle (v) Solar hour angle b) At 400 N latitude (φ) Determine (i) The direct normal extra-terrestrial irradiance (I0) at equinox (ii) Solar declination angle (δ) at equinox (iii) the sunrise time, sun set time and day length (a) at Equinox (b) at Summer Solstice (c) at Winter Solstice Following equations are given with their usual notations. I0=ISC[1+0.034cos(360 N/365)] where ISC=1353w/m2, δ=23.45sin[360(284+N)/365] where N is the day number from January 01 wSS=cos−1[−tanφtanδ] Sun rise time (Tsr)=12−Wss×1/15)hrs Sun set time (Tss)=12+Wssx1/15)hrs Day length (Td)=wss×2/15hrs
