1. TEMPERATURE RESISTANCE OF SOLAR PANELS

Solar panels consist primarily of photovoltaic (PV) cells, which are created from semiconductor materials like silicon. These materials are engineered to convert sunlight into electricity efficiently. The capacity of solar panels to endure high temperatures is critical, especially in areas exposed to intense sunlight. While individual panels can vary, most commercial solar panel systems are designed to function optimally within a certain thermal range. Typically, solar panels can function at temperatures exceeding 85 degrees Celsius. However, functionality does not mean these temperatures are ideal for performance.

High-temperature influence manifests through decreased efficiency in energy conversion. When the temperature exceeds optimal levels, the electrons in the silicon cells become more energized, leading to increased resistance. This resistance contributes to reduced output, as energy conversion is less efficient. Moreover, elevated temperatures can accelerate the degradation of materials, particularly those in the back sheets and encapsulants, potentially impacting the longevity of panels. For this reason, the careful selection of materials and technology is essential in assuring that solar panels maintain their integrity and performance over time.

2. EFFECTS OF EXTREME HEAT ON SOLAR PANEL PERFORMANCE

The performance of solar panels under high-temperature conditions must be scrutinized closely.
