Solar planner
Plan the roof before you buy it
Pick your coach, lay panels around the air conditioners, and walk away with three systems sized down to the fuse. Fleetwood models are first in line.
How the planner works
Loads come from the original Megawatt battery table, plus anything you add. The array is daily watt-hours ÷ (sun hours × 0.75). Weekend uses up to as many 200 W packs as the roof holds, Boondocker uses the minimum array, and Off-grid adds 15 percent.
Each tier runs the original battery calculator for 1, 3, or 7 days. The inverter is your peak plus 25 percent, rounded up to the next 1,000 W. The controller is array watts ÷ bank volts × 1.25, rounded up to a common size. Wire comes from the Megawatt copper table at 3 percent drop.
This is a plan, not a permit. Have a certified electrician or installer review it before you drill the roof or wire a bank. Roof layouts ignore ladders, antennas, and curvature.
