**3. Problem formulation**

Increase in energy expenditure and worldwide dependence on fossil fuels lead to power shortages and global warming. Generally the diesel generator is used in both on-grid and off-grid systems for a reliable power source [11, 21]. This is a costly and also causes environmental toxic waste. In the country there is enormous resource of renewable energy source that is not being effectively utilized. Reliable renewable hybrid systems need to be developed by using the available renewable sources These hybrid systems can be a viable option in universities, companies, hospitals, industry and rural communities to fulfill the energy needs. The construction of such systems needs detailed study of renewable energy supplies by the location, because without this the hybrid device may be massive, which raises the device expenses [12, 22].

In order to investigate the financial and technological viability of the hybrid energy systems, the feasibility of dissimilar systems configurations and energy requirements needs need to be analyzed and analyzed.
