DESIGN OF ROOFTOP SOLAR PV

In a view of global energy scenario and to meet increased demand for energy, solar energy has been harvesting at faster rate across the world. To achieve the goal of sustainable development the maximum use of renewable resources is essential. In that respect, solar energy harvested in different ways such as solar thermal, solar photovoltaic etc. Similarly a solar photovoltaic systems have different configurations like, grid-connected, stand-alone which are either on ground surface or on rooftop. In this paper the grid-connected solar rooftop PV (RTPV) for Government College of Engineering, Aurangabad has discussed. Under Net-metering policy for the state of Maharashtra for grid-connected RTPV, the CAPEX model and the RESCO model are discussed. Estimation of RTPV capacity for given site is done based on contract demand or sanctioned load, utility distribution capacity and available shadow free area for RTPV installation. With estimated capacity of 119 kWp, the annual saving in electricity bill and payback period calculations are done in section-IV.
