Control Motion of Solar Panels

Abstract

– In present work, we simulate designing a tracking system to keep the solar panel aligned with the sun. We demonstrate this system as motion according to sun position in the sky all day. This motion was presented by some ordinary differential equation that represent the trajectory of variables (theta, d_theta and etc.), by implementing an electric motor to drive the solar panel. A PI controller was applied to track the actual path of the sun, it gave us a good response in real time from sun rising (22 deg.) to sunset (322 deg.) for Azimuth at USA and from (0 deg.) sunshine, (60 deg.) mid-day to sunset (0 deg.).
