Pengaruh Bentuk Rangkaian Panel Surya Terhadap Kuat Arus, Tegangan dan Daya

Abstract

The purpose of this study was to determine the effect of solar panel circuits on current, voltage and power. This research is a true experiment. Dependent variables were current, voltage, and power. Independent variables were a series circuit of solar panels and a parallel circuit of solar panels. The sample numbers of studies were 12 for each group of independent variables. The data were analyzed using the t-test at the 5% signification level. The results showed that the electrical power produced by a series circuit of solar panels was, P = 4.81 watt, Sd = 0.24. The electrical power produced by a parallel circuit of solar panels was P = 4.69 watts, Sd = 0.13. The t-test showed that there was no difference in electrical power produced by the series circuit of solar panels and parallel circuit of solar panels, with t_o = 1.525 < t_{α/2, v} =2,074. The form of a circuit (series or parallel) has no significant effect on power but differs only in current and voltage. In series circuit, I₁ = I₂ = I_Σ and V₁ +V₂ = V_Σ. In parallel circuits V₁ = V₂ = V_Σ and I₁ + I₂ = I_Σ. This can be adjusted to our purpose of using solar panels circuit. If it requires a large current, the solar panels must assemble in a parallel circuit. But if it requires a large voltage, the solar panels must assemble in a series circuit.
