Photovoltaic modules are tested at a temperature of 25° C - about 77° F, and depending on their installed location, heat can reduce output efficiency by 10-25%. As the solar panel's temperature increases, its output current increases exponentially while the voltage output decreases. . This increase is associated with the absorbed sunlight that is converted into heat, resulting in reduced power output, energy efficiency, performance and life of the panel. The use of cooling techniques can offer a potential solution to avoid excessive heating of P. panels and to reduce cell. . l expansion is one of many important structural design considerations. In fact virtually all materials exhibit some linear dimensional change as a function of temperature change and accordingly, a Coefficient of Thermal Expansion is material property that is typically determined by empirical. . Even in Hawaii, panels and racking can experience temperature swings totaling more than 100°F. Increase in temperature affects the semiconductor material parameters by increasing the energy of bound electrons.
