The focal point of this study is to recreate and plan a hybrid system
consisting of a solar photovoltaic, a battery and a diesel generator and optimize the
configuration into an off-grid hybrid structure to meet the electricity demand of an
institutional area situated in Jaipur, Rajasthan, India. Various configurations have
different specifications obtained to meet the load demand based on input parameters
which are obtained from a pilot survey and the main survey a particular location.
Various costing parameters such as per unit of cost and net present cost are estimated
with the condition of meeting the maximum load demand. The HOMER (Hybrid
Optimization Model for Electric Renewable) software is used for different simulation
processes and finally it is found that solar PV-battery-diesel generator hybrid system is
an economical system to meet the electricity demand in which the cost of energy is
obtained as ₹ 13.83 and Net Present Cost is ₹ 9.78M with initial capital and operating
costs of ₹ 4.20M and ₹ 646,319 per year, respectively. The diesel fuel cost is obtained
as ₹ 5,09,288 per year. Meanwhile, the electricity produced and consumption are also
estimated as 1,09,040 kWh/year and 81,939 kWh/year, respectively, with an unmet
load of 1.77% only.
