A free planning worksheet that turns your solar calculator result into a practical first parts list before you start buying panels, controllers, fuses, and wire.
The file stays lightweight on purpose: enough structure to capture the parts, assumptions, and checks that matter without forcing every rig into the same plan.
Three build lanes
Starter, balanced, and buffer-heavy lanes help you avoid buying either too little solar or a system that does not fit the roof.
Installed solar target and battery reserve notes
Charge controller sizing checks
Portable-panel decision points
Pre-buy compatibility checks
Use the checklist before checkout so the smaller support parts do not become the bottleneck.
Roof fit and shade checks
Fuse, breaker, disconnect, and wire questions
Low-temp and battery charging compatibility
Calculator-to-parts handoff
A short worksheet captures the assumptions that matter when the calculator answer becomes a real parts plan.
Daily watt-hours
Sun-hour assumption
Recovery target and reserve days
How to use it
Use the file after the math, not before it.
The worksheet works best after you have a real calculator result. It slows the decision down just enough to catch fit, safety, recovery, and daily-use assumptions before you buy or build.
1
Run the calculator first
Use your real appliance loads and sun conditions so the parts list starts from a math target, not a forum guess.
2
Pick the lane that fits the rig
Choose starter, balanced, or buffer-heavy based on roof space, travel style, and tolerance for cloudy-day generator time.
3
Verify the small parts
Check controller limits, wire distance, protection devices, mounting clearance, and battery charging rules before buying.
Use this when
You have a daily watt-hour estimate and need to translate it into a buy list.
You are comparing roof solar, portable solar, or a hybrid setup.
You want to check controller, fuse, wire, and battery questions before ordering parts.
LimitsWhat this resource does not replaceThe resource helps you plan. It does not replace current specs, manuals, code requirements, or installer judgment.

Optional follow-up
What the follow-up emails keep from slipping.
The download is useful by itself. The matching follow-up path keeps the next few decisions tied to the same planning problem instead of scattering them across tabs, notes, and shopping carts.
