Quick Answer
Monocrystalline panels can be installed in high-wind areas, but it's essential to consider the structural integrity and stability of the mounting system to ensure the panels can withstand strong gusts without damage.
Assessing Wind Loads
When installing monocrystalline panels in a high-wind area, it’s crucial to assess the wind loads and ensure the mounting system is designed to withstand them. This involves calculating the wind pressure and selecting a mounting system with a high load capacity. For example, a wind speed of 120 mph (193 km/h) can generate a wind pressure of up to 100 pounds per square foot (psf). In this scenario, a mounting system with a minimum load capacity of 200-250 psf would be required to secure the panels.
Choosing a Suitable Mounting System
A suitable mounting system for high-wind areas should have the following features: a sturdy frame, reinforced brackets, and a secure connection to the roof or ground. Some popular options include ballasted racking systems, which use heavy weights to secure the panels, and bolted racking systems, which use reinforced brackets to attach the panels to the roof. For example, the IronRidge XR100 roof mount system can withstand wind loads of up to 350 psf.
Additional Considerations
In addition to selecting a suitable mounting system, it’s essential to ensure the monocrystalline panels themselves are designed to withstand high winds. Look for panels with a high wind rating, such as the LONGi Solar LR6-60HPB5 module, which has a wind resistance rating of up to 240 mph (386 km/h). It’s also essential to secure the panels’ electrical connections and wiring to prevent damage from debris or moisture.
