Influence of the Intensity of the Solar Radiation and the Surface Area of Photovoltaic Module Towards the Electricity Generated by Photovoltaic Module

Abstract

The intensity of the solar radiation and the surface area of the photovoltaic module directly influence the amounts of electricity produced by the photovoltaic module. This needs to be known to determine the design of an effective solar power system for the use of electricity from solar energy sources. This research aims to determine the influence of the intensity of solar radiation and the area of the photovoltaic module on the performance of the photovoltaic module in producing current and voltage to be distributed to charge the battery. The method used in this research is an experimental method that measures the current and voltage of the photovoltaic module, the intensity of the solar radiation, the temperature, and the surface area of the photovoltaic module the equipment used is 600 Wp photovoltaic module, ammeter, voltmeter, luxmeter, solar charge controller, batteries and temperature gauges. Results of the research show the intensity of the solar radiation is directly proportional to the battery charging current. The intensity of the solar radiation up to 10000 lux produces a charging current on a 100 Ah 12 volt battery that is 0 to 1.55 Amperes, for 10000 lux to 60000 lux produces 1.6 to 8.35 A, for 60000 lux to 90000 lux produces 9 to 14 A and for above 90000 lux produces 14 to 19 A. The ratio of the surface area of the photovoltaic module is proportional to the ratio of the battery charging current and the increase in battery voltage. Photovoltaic modules with a surface area ratio of 1:2:3, produce a battery charging current and voltage that is 1:2:2.7 and 1:2.1:3.1. Comparison of the amount of electricity produced by a photovoltaic module is proportional to the ratio of the surface area of a photovoltaic module if the measurements are made at the same place and time, at the same scc (solar charge controller) and at the same initial voltage of the battery.
