Is it necessary to cover solar panels during storms?

Storm Resistance for Boat and Marine Solar Systems

When it comes to boat and marine solar systems, flexible panels are often a popular choice due to their durability and ability to withstand harsh salt environments. Flexible panels can withstand winds of up to 150 mph and hail impacts up to 1-inch in diameter. However, it’s essential to secure them properly to prevent damage from excessive wind loads.

Protecting Solar Panels from Hail and Debris

While standard rigid panels may benefit from covering during storms, flexible panels are less likely to be damaged by hail or flying debris. Nevertheless, if you’re using a rigid solar panel system, consider investing in a sturdy cover or windscreen to protect them from damage. A good quality cover can be installed for around $100-$300, depending on the size of the solar array.

Charge Controller and System Considerations

When designing a marine solar system, it’s crucial to select a charge controller that can handle the unique demands of the marine environment. Look for a charge controller with a high surge capacity, such as the Victron Orion-Tr 12/12-30A, which can handle up to 30A of current. Additionally, consider using a system with a built-in protection feature, such as a fuse or circuit breaker, to prevent damage to the solar panel array in case of an electrical fault.
