Solar insolation was assumed to be 2000 kWh m-2 year-1, typical of northwestern desert regions in India. The installation consists of a basic array of fixed flat plate systems with approximately 3500 multi-crystalline silicon (120 Wp m-Si) PV modules (approximate module area of 1m2) with an efficiency of 15% (an output of 400 kWp ha-1) (e.g. Ito et al., 2007) [28]. The annual power generation is calculated via the HOMER model utilizing a solar resource of 5.80 kWh m-2 day-1. HOMER (Hybrid Optimization of Multiple Energy Resources) software models micropower systems with single or multiple power sources. HOMER finds the least cost combination of components that meet electrical and thermal loads by simulating thousands of system configurations, optimizing for lifecycle cost, and generating results of sensitivity analyses on most inputs.
