Quick Answer
Solar panels are designed to withstand various weather conditions, but extreme weather can cause damage or compromise their performance. Leaving them mounted during severe weather is generally safe, but proper installation and maintenance are crucial to prevent damage. Check your panels' specifications and certification for wind and snow loads.
Understanding Solar Panel Mounting
Solar panels can be mounted using various methods, including roof mounts, ground mounts, and trackers. For van life setups, roof mounts are a popular choice due to space constraints. Ensure your roof mount is designed to withstand the wind loads in your area. In the US, for example, the American Society of Civil Engineers (ASCE) recommends wind loads of up to 40 pounds per square foot (psf) for residential buildings.
Safety Considerations for Severe Weather
When facing severe weather, secure any loose outdoor components, such as panels, wires, and conduit, to prevent damage or flying debris. Consider using cable ties or zip ties to secure loose wires and cables. For lithium batteries, ensure the charge controller is set to “equalize” mode when the system is not in use to prevent damage from over-discharge.
Maintenance and Inspection
Regular inspections and maintenance are crucial to ensure your solar panel system operates safely and efficiently. Check for damage to panels, wires, and mounting hardware after severe weather. Clean debris from panels and ensure proper ventilation around the system to prevent overheating. Consult your manufacturer’s guidelines for specific maintenance recommendations and follow local building codes and regulations.
