More Efficient Use Of Photovoltaic Solar Panel Using Multiple Fixed Directed Mirrors Or Aluminum Foils Instead Of Solar Trackers In Rural Perspective Of Bangladesh.

摘要

Abstract: The main objective of this paper is to show the potential use of a solar panel using multiple fixed directed mirrors or aluminum foils as a reflector instead of ordinary solar tracker in rural perspective of Bangladesh. The solar panel only receives direct beam of sunlight and diffused sunlight. Experiment shows that if we use reflector (mirror or aluminium foil) to concentrate sunlight onto PV panels, each individual panel receives a lot of additional power. As a result, the number of solar panels needed to produce a certain amount of power can be reduced, and the money spent on ordinary solar trackers which are more expensive than reflectors is saved. This, therefore, is a cost-effective way - which allows solar energy to be more accessible to the rural people of Bangladesh-to generate more amount of solar power with less number of panels and a lower cost. With the help of multimeter we recorded the received power of a photovoltaic solar panel using reflector (mirror or aluminium foil) and without using reflector and compared this for calculating the performance of a panel. The simulation program is created in Matlab. Different assumptions are taken to make the system realistic and to reduce the complexity.
