In academic as well as extracurricular activity, there is a need of undisturbed electric supply in hostels. But, due to certain constraint, the civilian electricity supply doesn't meet the demand. In such case, alternative source, such as rooftop solar power supply plays a vital role. A case study has been done at University Boys’ Hostel of Dr. RPCAU, Pusa. In this paper, assessment of rooftop solar power availability has been done to achieve the power requirement of university boy’s hostel. Further, a layout of solar power plant has also been proposed. In this study, after designing the layout plan, a financial assessment of the project has also been done, considering recent market price. The entire planning has been carried by considering the actual space available at the roof top for installation of the solar panels. The results from this study suggest that total total power requirement in university boy’s hostel to meet the load was about 43 kWp /day. And also total cost of installation was about Rs 52 lakhs. Keywords: Solar power, rooftop solar panels, off grid solar PV, financial assessment, photovoltaic Introduction The use of renewable technology for generating power is growing at a faster rate in the current era. Considering the low availability of conventional fuels and the constant price increase, the use of solar power must be used to its fullest in areas where solar radiation is available throughout the year. The sun is radiating an enormous amounts of energy, called solar energy and it radiates more energy in one day than the world uses within one year. Every hour enough solar power reaches on the Earth to supply a year's energy requirement for our country. Like most stars, the sun is a large gas ball mainly made up of Hydrogen and Helium gas. In a process called nuclear fusion the sun makes energy in its inner core. India lies between latitude 7 o North and latitude 37 o North. The average incident of solar energy over India ranges from 4-7 KWh / m 2 , with around 1500-2000 hours of sunshine a year. Solar cell is a device that directly converts the energy of light into electrical energy through the photo-voltaic effect and its does not emit any harm full gases. This paper presents a complete assessment of a PV plant for RPCAU Boys Hostel at Pusa which consisting of five blocks. The concept of developing environmentally friendly photovoltaic plants has been discussed, (Chen et al., 2012) [8] and suggests that enormous green energy source produced from the sun would gain the best opportunity to grow up. We will seize the ability to build the most suitable environmentally friendly PV power plant. Considering this as an opportunity to suggest a clean source of energy for complete energy demand of the RPCAU boy’s hostel, a solar PV plant design and its assessment has been carried out. A case study in Jaipur (Khatri R., 2016) [1] designing and assessment of solar photovoltaic plant to meet girls hostel energy demand at MNIT University Jaipur. A solar PV plant was designed with its financial and environmental assessment considering recent market prices. All the aspects related to a solar PV plant were considered for financial feasibility of PV plant near this location. A study was carried out on solar cell (Ilyas et al. 2013) [2] , Solar Photovoltaic Technology, Planning and Designing a Stand Alone Solar Power System for Multi Building in
