Pros
- Genuinely free to run — the sun does the heating; you only pay for the filter pump that's already circulating the water
- Industrial-grade panels rated for a 15–20 year life, with an over-molded single-piece header that resists the leaks that plague cheaper DIY kits
- Configured to your pool, not one-size-fits-all — choose the panel count, panel size (4×8 up to 4×12 ft) and header diameter (1.5" or 2"), scaling from a couple of panels to ten; a real roof/rack system, not an above-ground coil
- Complete DIY kit (all mounting hardware + plumbing) that ties into your existing pump, with US-based install support
Cons
- Only adds heat while the sun is out — it can't hold a target temperature on cold or cloudy days, and does nothing at night
- Real upfront cost and effort: a panel system runs several hundred dollars and needs south-facing roof or rack space plus a DIY install
- Gradual by nature — sized right it adds roughly 10°F over a sunny stretch, but it won't rescue a cold pool on demand the way gas does
- Buy every panel you think you will need at once: an owner adding to a 2021 order was told by SolarPoolSupply's own support that the panels now come from a different manufacturer and the connectors no longer match
Almost none. One owner says the system needs a lot of heat to do anything and a return was refused; another, replacing a 12-year-old system, had tightened its hose clamps every year and swapped a rubber boot or two.

“They were simple to install. Packaged very nicely. My pool went from 75 degrees to 88. I have set it to 90 and it heats to that no problem. Huge savings vs natural gas. I highly recommend.”— David J., SolarPoolSupply · Verified owner

Yes as far as the document goes: SolarPoolSupply's warranty carries no authorized-dealer, unauthorized-reseller or marketplace condition — we checked the full text on 2026-09-14.

Record
- — Re-read: 4.7 across 69 ratings, up from 4.6 across 61 in June, with only two critical reviews. That rating is shared by every panel count and size on the listing, so it describes the panel system rather than the four-panel kit shown here. One owner reports that the panels now come from a different manufacturer than a 2021 order, with connectors that no longer match.
