Quick Answer
To measure your RV roof for solar panels, you'll need a tape measure or a laser measure, a calculator, and a diagram or sketch of your RV's roof layout. You should also consider the size and spacing of the solar panels, as well as the roof's surface and structural integrity.
Measuring Your RV Roof
To accurately measure your RV roof, start by gathering a tape measure or a laser measure. These tools will allow you to measure the length, width, and any obstacles on your roof, such as vents, skylights, or antennas. Take note of any obstructions that may affect the placement of your solar panels.
Calculating Solar Panel Space
Next, calculate the total available space on your RV roof by measuring the length and width of the roof. Consider a minimum of 1 inch of clearance between the solar panels and any obstructions, such as vents or skylights. For example, if your RV roof measures 10 feet by 20 feet, you’ll have 200 square feet of space available for solar panels.
Roof Layout and Panel Sizing
When determining the size and spacing of your solar panels, consider the total wattage you need to generate, as well as the roof’s surface and structural integrity. A general rule of thumb is to space solar panels 3-6 inches apart, depending on the size of the panels. For example, if you’re using 60-cell solar panels that are 39.6 inches by 65.6 inches, you’ll want to space them 4-5 inches apart to allow for good airflow and ease of installation.
