Techno- Economic Evaluation and Improvement Possibilities of Local Grid Connected House – PV Power System

The daily average of solar radiation intensity on horizontal surface in Palestine is 5.4 kWh/m²-day while the total annual sunshine hour amounts to about 3000. The implemented renewable energy projects in Palestine are focused on PV applications, as a part of its concentration on solar renewable energy PENRA setup the Palestinian Solar Initiative(PSI). The initiative target is to achieve 20 MW by 2020 through installing PV panels on the rooftops of households with 5 kWp for each house. This thesis discusses the rooftops PV systems, the techno-economic issues, improvement possibilities, and environmental analysis of such systems. Three houses in Tubas area are studied, the energy produced by house no.(1) is 8496.6 kWh/ year then the total average revenue is 8759.33 NIS/year, and the annual saving after paying the electrical bills to the company is 5,690.34 NIS/year. House no.(2) produces 9617.66 kWh/year, the total revenue is 9,914.44 NIS/year, and the annual saving after paying the bills is 6,978.64 NIS/year. House no.(3) produces 9304 kWh/year, the total revenue is 7443.200 NIS/year, and the annual saving 5596.59 NIS/year. Economic analysis shows that the cost of 1kWh produced by these systems is 0.40 NIS. Environmental analysis shows that these systems preserve the environment of production CO2, house no.(1) reduces CO2 by 7,919.08 kg/year, house no.(2) reduces CO2 by 9,006.62 kg year, and house no.(3) reduces CO2 by 8,702.26 kg/year.
