Economical Feasibility for Using Solar Cells and Diesel Units To Supply A Rural Isolated Society

This paper introduces an integrated study concerning the technical and economical sides for supplying the electrical loads of a rural isolated society or small isolated village represented in Almazraa village relevant to Nawa Town located at the north western of Daraa Governorate at a distance of about 30[Km]. The followed methodology of this study aims at the comparison between two states required electrical loads according to special scenario of each state, the first scenario represents the feeding of special loads of a daily lifetime activity performed by the inhabitants of this village representing a case of typical rural society, and the second scenario adding the loads of irrigation of surrounding agricultural lands to the first scenario. For supplying the required loads then making a comparison between two choices, the first choice is the usage of solar cells as a renewable energy source, while the second choice is the usage of diesel generation units as a traditional energy source. This paper included the preparation of the mathematical model of previous system then to determine the volume of this system for each of the two cases of loads and the previous two choices of energy sources. The preparation of computer programs of previous study because of the easiness of projecting them two similar cases. The research also included an economical study of the previous cases then coming through them into the computation of fixed cost or construction cost, running cost and the annual cost and then estimating the production cost of Kilo Watt-hour and to identify the more economically feasible of choice. Then to complete this study by focusing on the volume mass of contamination wastes caused by the daily work of diesel units and presentation of the economical importance for the usage of solar cells especially in the isolated areas and in the rural and agricultural societies as economical choice and without an environmental damaging wastes.

Structure a New Thermal Hydraulic Autonomic Solar Tracker

The research includes the main ideas, outline and preliminary structure for designing the proposed thermal hydraulic autonomic solar tracker. Who enjoys the benefits outweigh known trackers, raising yields and minimize energy expended, reduced vibration through hydraulic movement. This makes the suggested tracker outweigh the Clifford-Eastwood-Tracker. Disadvantages of the proposed Tracker also much lower than the disadvantages of known passive trackers for variable intensity of solar radiation including the effect of clouds.
