Abstract

This research paper investigate the effect of tilt angle on the accumulation of dust PV module on energy production and presents a module for predicting soiling losses for eight different tilt angle (00, 50,11.60,150,21.50,250,300 and 350) including the latitude of Bahir Dar city (11.60) and 21.50tilt angle of 10Kw hybrid solar power plant PV module which is currently installed in Bahir Dar university. The study has shown that during the experimental investigation period there was total loss of insolation due to soiling was 32.32% and 4.8KWh/m2 total energy has been absorbed at 0° tilt angle. Modules at 11.6° and 21.5° tilt angles the total insolation loss were 21.92% and 16.78% respectively since it has been covered with dust. Approximately both modules have 5.3KWh/m2 of energy has been absorbed. However, at 250 tilt angle had a least insolation loss and largest amount of energy absorbed when compared to the remaining seven different tilt angles; it has only 10.77% of insolation loss and 5.7KWh/m2 of energy has been absorbed. The remaining tilt angles of 5°, 15°, 30° and 35° the total insolation loss were 25.45%, 19.08%, 14.20%, and 12.54% respectively, and also the total energy of 5.08KWh/m2, 5.52KWh/m2, 5.2KWh/m2 and 4.59 KWh/m2 were absorbed respectively. Thus, soiling effect has present at any tilt angle, but the magnitude is evident: the flatter the solar module is placed the more energy it will lose.
