Mention solar panels or solar arrays to the average citizen, and thoughts of long, sunny days and moderate to high temperatures might enter their mind. Perhaps some might even envision a semi-tropical locale with gentle breezes wafting by. Most (if not all) solar panel installers wish that type of location was the reality. In truth, however, while sunlight is the prime factor in placing solar panels in order to maximize their usefulness as energy receptors, solar installation sites are not always warm and comfortable.
In many instances, solar installations are positioned in harsh climates and difficult locations. Because of this, all the non-solar-cell components have to be tested and found able to withstand conditions ranging from deep frosts to extreme heat, as well as high winds, ice, snow, sleet, rain, and any other type of potentially damaging moisture—even debris impingement. The various elements that make up the finished module must prove to be consistently able to perform, whether in an industrial array or for consumer use.
