Solar energy offers a passive way to heat water using panels, but it may take a little time to heat the pool, and it’s only effective when the sun is shining. While solar panels can help reduce the costs of heating your pool, they lose about 70% of their heat during the night, which means you will definitely need another heating system as well unless you live in a place with warm or hot heat year-round.

A solar heating system produces more energy to heat pool with more panels, which may cause a significant increase in the start-up cost of solar pool heating systems. You may want to consider more panels and take into account how much roof space you have for the solar panels. Solar heating does come with the benefit of low costs and a limited effect on the environment.

The technology is still relatively new and is only just becoming effective but with a lot of room for improvement. Yet, solar panels cost nothing after the initial cost, which is competitive with both gas and heat pump options.

What To Consider Before Purchasing A Solar Pool Heating System

Overall, solar panels, as they are now, tend to work better for above-ground pools, but as technology improves, so will our ability to harness the solar power of the sun. Until then, you will need to keep a few things in mind before deciding to purchase a solar pool heating system for your backyard pool.

Pool Style

In-ground pools are hard to heat with solar power than above-ground because the solar panels then need to constantly work against the temperature of the ground as well as the water in the pool.


If you live in a warmer climate, you may only need a little extra heat, which solar power can easily provide. For those in colder climates or more shaded climates, you may not get enough solar power to reach your desired heat from unpredictable sunlight. A leisure swimming pool should maintain a temperature of 88-90 degrees, those using the pool for exercises will only need to maintain a temperature of about 78 to 85 degrees, which is much easier to do with a solar-powered heater.

Installation & Warranty

The cost of hiring a professional significantly increases the price of the solar panels, and it would take longer for them to make up the money you spent for the set. You will also want to consider the warranty because it’s often how long an item will last. If something breaks after only a couple of years and there is no warranty, your investment might be completely useless unless you manage to fix it yourself.

Distance to Your Home

If your pool isn’t close enough to your house, you may need to put the solar panels on the ground, which creates more risk of them getting ruined. Too much distance can reduce the effectiveness of the exchange though you could make a dedicated wooden rack closer to your pool for the panels.

FAQ about the Best Solar Powered Pool Heaters

Here are answers to some common questions asked about solar powered pool heaters:

How do solar pool heating systems work?

Solar pool heating systems work by harnessing energy from the sun into a panel to prompt heat into the water with focused light before circulating the water back into the pool. Another option is a solar cover for a pool that would transfer energy into the top couple of layers of water. Use this in combination with your water pump to filter water, as well.

Hotter climates can use solar collectors to either heat or cool down a pool. Some systems use sensors and valves (either automatic or manual) to diver water through a collector until the temperature is greater than the pool temperature. When the temperature is the same as the collector’s wit will bypass the panels and return to the pool.

Mind you, solar energy is not quite as exact as electric or gas heat because the sun produces the heat. The sun constantly puts out heat, but the atmospheric conditions create variables that make it not as consistent as the other two options.
