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.

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.
