What are Solar Pool Heaters?

Solar pool heaters are a lot different from the solar panels you’re probably accustomed to hearing about/using. Instead of producing electricity, solar pool heaters take in thermal energy produced by the sun to gradually heat passing pool water. If you’ve used a garden hose that has been laying in the sun all day, the heated water in the hose is what you would get, though at a grander scale.

Important Considerations before Choosing a Solar Pool Heater

1. Compatibility

First and foremost, you need to understand that solar pool panels are not the best type of pool heater for everyone. A number of different factors can affect its overall performance, including climate, amount of direct sunlight, wind, and shading. For instance, if your pool, yard, and home are completely shaded by large oak trees, you might want to consider looking at other pool-heating options (gas or electric).

2. Pool size

You need to know how large, wide, and deep your swimming pool is. The more water it can hold, the longer it will take to raise the temperature of your pool. In general, each square foot of pool surface will require at least one square foot of panel to heat up efficiently, although you can go slightly lower if your budget or space can’t allow a 1:1 ratio.

3. Mounting Spot

Speaking of space, you should determine which spots around your pool get the most sunlight. The more sunlight there is, the quicker the panel will raise the temperature of passing pool water. Rooftops, fences, DIY racks, and even the ground around your pool are fine spots to mount your solar pool heater panel, though you should determine how much space you can actually allocate to the panels.

4. Pump Size

How large is your pool pump measured in horsepower? Your pump should be able take water from your pool and push it through the panel. If you’ve mounted your solar pool heater on the roof, a 1.5-HP pump should be sufficient in fighting against gravity. If the panels are sitting at the same height as your pool, then your current pool pump should do the trick.


How many solar panels are needed to heat a pool?

Ideally, you’ll want to get one square foot of a solar panel for each square foot of pool surface. However, shading, winds, and the amount of direct sunlight are just a few of the factors that can affect the effectiveness of the panel. You should consider hiring a qualified solar contractor to help you determine how many panels you need.

When should I turn on solar pool heater?

The way a solar pool heater works is by turning on a pump that takes water from your swimming pool and passes it through the solar panel. You’ll get the best results when running the pump during the sunniest times of the day or when the panels get direct sunlight.

Is a solar pool heater worth it?

They can be, depending on where you live and how hot it gets for how long. As their name suggests, solar pool heaters rely on the natural heating power of sunlight to bring passing water up to a comfortable temperature. On average, a solar pool heater kit pays for itself in just two years by reducing the cost of running a gas/electric pool heater.

How long does pool solar heating last?

The longevity of each pool solar heater unit varies from model to model, although the general lifespan of each panel is anywhere between 5 and 15 years. As long as you take the necessary precautions when rolling and unrolling the panel(s) as well as mounting it correctly, you should enjoy at least a decade of properly heated pool water without any added costs.
