Design and regression analysis of solar tracker through system sun tracker

Abstract

Designing and regression analysis of test result solar tracker has been done. The instrument use Arduino Uno as mikrokontroller, sensor LDR, motor servo, panel surya and LCD as viewer of result test. From result test about arduino uno that show output 1, 0, 1, 0, 1 since 5 secon. Testing panel surya show average voltage about 5.84 volt since 5 secon. Testing LCD show 0 for bright condition and 1 for dark condition. Testing motor servo show variation value in 5 steps. Regression Analysis from testing instrument are compare value of voltage from the standart measurer with instrument that design. The source energy that use to instrument is light sun. the data show the value of standar deviasi are (δ) 0, 075, so (UA1) = √ δ η = 0, 075√20 = 0, 017. The equation of regression is (Yreg) yaitu Yreg) = α + bx = 0.0096 − 0.0035x. so the value of uncertainty approaching regreesion are UA2 0.013. with value of uncertainty approaching regreesion show the instrument of solar tracker is good work.
