Abstract

It was intended to reveal the time dependent power generation under different loads for two different solar panels under the conditions of Bursa province in between August 19 and 25, 2014. The testing sets include solar panels, inverter, multimeter, accumulator, regulator, pyranometer, pyrheliometer, temperature sensor, and datalogger. The efficiency of monocrystalline and polycrystalline solar panels was calculated depending on the climatic data’s measurements. As the result of the study, the average performances of monocrystalline and polycrystalline panels are 42.06 and 39.80 Wh, respectively. It was seen that 87.14 W instantaneous power could be obtained from monocrystalline solar panel and that 80.17 W instantaneous power could be obtained from polycrystalline solar panel under maximum total radiation (1001.13 W/m2). Within this frame, it was determined that monocrystalline solar panel is able to operate more efficiently under the conditions of Bursa compared to polycrystalline solar panel. When the multivariate correlations coefficients were examined statistically, a significant relationship in positive direction was detected between total and direct radiation and ambient temperature on energy generation from monocrystalline and polycrystalline panel.

Summary

Introduction

One of the most significant requirements of developed and developing countries is energy. Even if there are various methods of energy production and consumption, all the countries require cheap, large, and clean energy sources [1]. The use of energy sources which cannot be renewed at a large extent had significantly increased the environmental problems. Tendency towards renewable energy sources with low environmental effects is advantageous in all aspects [2]. Renewable energy sources are defined as energy flows which are replaced at the same speed as they are used. All renewable energy sources on Earth arise from the effect of solar radiation which can be directly or indirectly converted to energy by using different technologies
