Quick Answer
Incorrect installation of flexible solar panels can lead to reduced efficiency, premature aging, and even complete failure. Water ingress, excessive heat buildup, and mechanical stress can all compromise the integrity of the panel. In severe cases, this can result in a complete loss of the investment.
Installation Risks
Flexible solar panels are highly susceptible to installation errors, particularly when it comes to ensuring a watertight seal. If the adhesive or backing is compromised, water can seep into the panel, causing corrosion of the electrical components and reducing the overall efficiency. A minimum of 1/8 inch (3 mm) of clearance should be maintained around the entire panel perimeter to prevent water accumulation.
Thermal Performance
Flexible solar panels are designed to operate within a specific temperature range, typically between -40°C and 80°C (-40°F and 176°F). If the panel is installed in a location where it can become excessively hot, such as in direct sunlight with inadequate shading, the efficiency can drop by up to 20%. This can lead to reduced energy production and a shorter lifespan.
Mechanical Stress
Flexible solar panels are vulnerable to mechanical stress caused by wind, snow, or other external forces. It’s essential to ensure that the panel is properly anchored to the roof or structure, using a minimum of 2 screws per panel for a secure hold. Additionally, a 1/4 inch (6 mm) gap should be maintained between the panel and any adjacent components, such as skylights or vents, to prevent damage from expansion and contraction.
