Abstract

Cost effective and hassle-free energy generation without causing environmental degradation is the need of the hour for saving mother earth and mankind from imminent devastation. Solar PV (SPV) energy generating systems are gifted solutions to overcome this acute problem. Energy generation using SPV systems is quite effective and efficient only if the SPV panels are aligned to be normal to the incident solar irradiation at all times during the day. This stringent requirement is fulfilled by mounting SPV panels on sun tracking systems. Single axis and dual axes sun tracking systems are widely used for generating a fairly good amount of energy by aligning the SPV panels to follow the sun throughout the day. This research paper presents experimental results and cost analysis to prove that a tilted single axis sun tracking system is a technically feasible and economically viable solution to this demanding requirement. Experimental investigation carried out over a period of one month during October,2016 has established that the energy gain of a tilted single axis sun tracking system turns out to be 31.91 % and that for a dual axes system is marginally more with just 35.3 %. Cost analysis of these systems has shown that the cost per kWh of generated energy for a tilted single axis sun tracking system is INR. 2.92and that for a dual axis tracking system is INR. 3.42, thus reiterating the fact that a tilted single axis sun tracking system can be used with advantage in low or medium power standalone SPV power generating systems.
