Array footprint

Will the planned array fit the space?

Start with the wattage range from the system sizer, then use one candidate panel’s datasheet dimensions to expose count and the minimum physical face area before drawing the real layout.

Array footprint planner

Turn array watts into panels and a physical area floor.

Use the exact nameplate power and dimensions from a candidate panel to expose the minimum module count and face area behind the array target.

Geometry boundary

Face area is the first hard floor, not the final layout.

Measure the unobstructed mounting area, then compare panel dimensions and placement in both orientations.

Planning brief

Carry the physical constraint into panel comparison.

Copy the target, panel format, count, area floor, and next placement check together.

What it answers

How many whole panels reach the baseline and pressure targets, and what installed nameplate range follows.

Hard floor

If clear area is smaller than the combined module faces, the candidate cannot fit before spacing and mounting are considered.

Next drawing

Use the manufacturer drawing to test both orientations, gaps, edge clearance, rails, obstructions, and cable routes.
