Pool dimensions & site
- Understand your number
What does your panel count actually mean?
Your panel count is just the start. How much pool you cover, how the roof faces, and whether your array is split, all of it shapes how the system performs in real life.
50% coverage
Light extension
You'll add a few weeks to either end of the swim season. Good for warm climates where you mostly want to take the chill off in spring and fall.
75% coverage
Most pool owners
The sweet spot. You can swim comfortably from spring through early fall, and your panels easily keep up with overnight heat loss.
100% coverage
Full season
For cooler climates, shaded yards, or anyone who wants to stretch the season as long as possible. Pairs well with a pool cover.
- Roof placement
Where the panels go matters too.
Most homeowners can fit their array on one roof. If you can’t, here are the common alternatives, all of them work.
Best
Single south-facing roof
The ideal, full panel array on one south-facing slope with no shade. You’ll get the full output the calculator estimates.
Common
Split across two roof faces
Plenty of installs run half the panels on east and half on west, or split south + west. Expect roughly 5–15% more panels to hit the same target.
Alternative
Ground-mount or pergola
No good roof? Panels can sit on a ground rack or a pergola near the pool. Plumbing runs are shorter and access for service is easier.
