DISTRIBUTED GENERATION BY GREEN AND SUSTAINABLE TECHNOLOGY USING SOLAR PV ROOF-TOP INSTALLATION

In the proposed work, solar rooftop PV generation analysis of existing distribution network in Pune (18.5204303°N,73.8567°S) consists of 3 residential buildings supplied by 100 kVA distribution transformer (DT) has been performed. Distribution side generation provides opportunity to increase system reliability and make the system sustainable. The Google earth, PVsyst and AutoCAD softwares are used to study the feasibility of solar rooftop installation on buildings. A methodology for estimating rooftop solar PV potential for buildings has performed. Global solar radiation on horizontal surface is converted into tilted surface radiation using mathematical formula derived from Liu Jorden model considering fixed tilt i.e., latitude. The energy output for hourly, daily and monthly is estimated for solar rooftop with elevated structure installation capacity of 31.78kW and 25.67 kW with nonelevated installation for both on-grid and off-grid system. In this proposed work PV generation is estimated using multi-crystalline and mono-crystalline PV module. The numbers of electrical vehicle batteries charged are 6000 if 4-wheeler and 30000 if 2- wheeler. Payback period is 14.8 years for non-elevated and 16.9 years for elevated installation.
