EXPERIMENTAL MONITORING AND COMPARISON OF ENERGY PRODUCTION ON SOLAR TRACKING SYSTEMS AND FIXED SUPPORT

The major objectives of researchers and industrialists in the solar field are to improve the efficiency and reduce the costs of cells, modules, and photovoltaic systems in order to make them as competitive as possible. There are two ways to maximize the useful energy rate by optimizing the conversion and degree of absorption, and by increasing the incident radiation rate by using mechanical steering systems. These systems, also known as solar trackers, allow the modules to be oriented throughout the day.The solar tracker, also called solar tracker, is a motorized arm that allows photovoltaic panels to follow the sun. Throughout the day, the arm rotates to capture as much sunlight as possible.For this work, we compared the production of panels mounted on fixed supports and trackers.The measurements were obtained on a year to make it possible to estimate the energy gain due to the orientation which is around 25%, thus confirming the economic importance of this systemProduction on tracker supports ramps up in the morning while production on fixed support gradually increases to its maximum at solar noon. The difference measured greatly exceeds at the beginning and end of the day the average is 44.5% for this sunny day. The greater the sunshine in the place considered, the greater the difference in favor of the tracker. On an annual average, the optimum gain of a 1-axis solar tracker varies by approximately 25% and 40% for 2-axis trackers compared to a fixed photovoltaic plant.
