Another design that affects the performance of the system is the ground slope. The ground of the pilot plant is horizontal and without slope. Researchers emphasize that soil design is an important parameter in improving the performance of the system [15– 17]. Ground is more important for SCPP than for other solar energy systems.
A solar power system should be checked by a qualified Clean Energy Council (CEC) electrician at least once a year, with the inspection covering the installation, DC isolators, panels, solar inverter, wiring, mounting array frame and system performance.
Visual Inspection of Panels. A thorough visual inspection is crucial for detecting possible issues in your solar panels. Start by examining the surface of the panels, looking for any cracks, dirt, or debris that might obstruct sunlight and hinder optimal performance.Shading maintenance is essential as it could affect the system''s efficiency.
