Optimum design of Rooftop PV System for An Education Campus Using HOMER

The energy demand is extremely growing day by day. This calls for alternate sources of energy. Renewable energy is one among the most effective solutions in meeting the increasing energy demand. It helps in reducing global carbon emissions and thereby lowers negative impacts on the environment. It also reduces the stress on the grid and demand for fossil fuels. Solar energy is a developing segment of our energy generation mix, and it will play a very important role in the future of energy production. Producing energy with solar panels has massive advantage over fossil fuels and found costeffective. A Grid interactive PV system feeds power into the grid and also generates power from the PV modules to meet their own needs. Educational institutes face energy crisis because of load shedding in the grid. This paper presents the optimal design and economical aspects of grid interactive PV system configuration for an educational campus also a comparative study is carried out for an on-grid PV system and off-grid PV-DG (Diesel generator) system. For the proposed optimum design of the PV system HOMER (Hybrid Optimization of Multiple Electric Renewable) software tool is used.
