Talk Title
SPV plant Efficiency and Sizing: A Case Study

Talk Abstract

The talk deals with the university solar Initiative such as: It is first Indian Univ. which is completely solar powered of capacity ~1MW SPV plant. It has Smart LT AC micro grid which is connected with city grid through 11/33 kV sub-station (run by university). The 7.5 kW sun tracking Solar tree designed and developed by Dept. of Electrical Engineering and agricultural work done below that. All hostel equipped with solar thermal systems for their kitchen needs. Campus has solar vane, e-vehicles etc. This presentation deals with a review of the energy efficiency in SPV systems with special reference to quantification and improvement of non-module system efficiency. The system efficiency (also called as performance ratio) is composed of photopic efficiency (losses in light energy before actually interacting with the SPV cell surface) and electrical efficiency (losses in electrical energy output generated by the module and before it is used by the load). System efficiency considerations are important in design of power plants for given end user loads. If the calculations are on the basis of kWpeak, a typical 100 kWpeak system gives a peak output of 50-65 kW at the load point due to system efficiency and also lowering of module efficiency due to non-standard operating conditions. System efficiency excludes auxiliary power, losses in battery and stochastic incident radiation loss. System efficiency presents possibilities of improvement to 75-80 % level through improved system design and improved operation and maintenance practices.
