Solar Pool Heating: A Different (and Cheaper) Kind of Solar

If you're researching "solar for my pool," you may be looking at two entirely different technologies — it's worth knowing which one you actually want before requesting quotes.

Solar pool heating vs. solar electricity

Solar pool heating panels circulate pool water directly through simple, unglazed panels (typically rubber or polymer) that absorb heat from the sun, warming the water as it passes through — no electricity generation involved. This is a completely different, simpler, and much cheaper technology than photovoltaic (PV) panels that generate household electricity.

Cost comparison

Solar pool heating systems typically cost $3,000-$6,000 installed for an average residential pool — a fraction of a full PV electricity system, and often cheaper than a comparable gas or electric heat pump pool heater over its lifetime, since there's no ongoing energy cost once installed.

Can you run a pool heater off your PV solar system instead?

Yes — if you have (or are installing) a PV electricity system, an electric heat pump pool heater can be powered by your solar production, effectively heating your pool with "free" daytime electricity rather than a dedicated solar-thermal pool system. This approach costs more upfront (a heat pump pool heater plus enough PV capacity to cover it) but consolidates everything into one system rather than running two separate types of solar equipment.

Which makes more sense for you

• Pool heating is your only goal: a dedicated solar pool heating system is almost always the cheaper, faster payback option.
• You're already installing or have PV solar and want to also heat the pool: size your PV system to include the additional load and use an electric heat pump pool heater rather than installing two separate solar systems.
