Temperature Balanca System for Big and Small-Scale Solar Energy Power Plants

Abstract

In recent years, the global energy landscape has been part of a remarkable transformation with the widespread inclusion of renewable energy sources, like solar photovoltaic (PV) systems. These systems, ranging from individual rooftop installations to expansive utility-scale solar parks, have emerged as pivotal players in the search for sustainable and clean energy generation. However, despite their promise, the performance of photovoltaic panels, especially in regions characterized by high irradiance levels, is not without its challenges. One of the biggest obstacles confronting the efficient operation of solar PV systems is the adverse impact of elevated temperatures resulting from intense solar irradiation. While sunlight is the primary source of energy for PV panels, excessive high temperatures can lead to a decline in their performance and efficiency, therefore diminishing the overall energy output. This phenomenon creates a significant concern for solar power generation, particularly in regions where irradiance levels have considerable heights.This study aims to analyze the weather data such as temperature levels, wind speed and irradiance, as well as the overall performance of photovoltaic panels, with a specific focus on solar energy power plants. By understanding the underlying reasons of the degradation of solar panels under high temperature conditions, this research aims to provide valuable insights into solutions that might improve the efficiency of solar energy systems. In this context, the studied data was sourced from fully operational solar parks located in the north of Chile, which user of lower efficiency in generation when temperature is on its highest levels, according to both the owner and the operator of the solar park. Through this study the objective is to suggest a solution which would solve this rise of high temperature in solar panels, to do this, different tests were carried on the powerplant, using the advantage of high wind speed and its cooling capacity, along side with the tracking system of the facility. After these experiments and results, this paper’s exposes the feasibility of a solution with the before mentioned characteristics, and supports further studies and recommendations for the proposed problem.
