Quick Answer
A 280-360 watt solar panel is a suitable size for a compact RV roof, with an average size of 48 inches wide and 65 inches long. This size offers a good balance between power generation and roof space usage. Panels of this size can be easily handled and installed, and they fit within most RV roof profiles.
Choosing the Right Solar Panel Size for Your RV
When selecting a solar panel for your compact RV roof, it’s essential to consider the roof’s dimensions, the available space for the panel, and the power requirements of your RV. A general rule of thumb is to aim for a panel size that fits within the width of the RV, which is usually between 48 and 60 inches.
Sizing Considerations
To ensure a proper fit, measure the length and width of your RV’s roof, taking into account any obstructions such as vents, antennas, or air conditioning units. Consider a panel that is at least 5-7 inches narrower than the RV’s width to accommodate any necessary clearance. This will also help to prevent water from accumulating on the roof and reduce the risk of damage.
Panel Sizing Tips
When choosing a solar panel, look for a model with a high efficiency rating (around 20-22%) to maximize power output from a smaller panel. A 280-360 watt panel with a 48-inch width and 65-inch length is a good starting point. This size can provide enough power to charge a small to medium-sized battery bank, which in turn can power essential appliances and devices within your RV. Keep in mind that a smaller panel may require more installation time and may not be as effective in low-light conditions.
