Pool Solar Collectors, also sometimes known as swimming pool solar panels are the most critical aspect of solar pool heat generation and will be the subject of my blog post today.

Sunlight (energy) which is radiated out from the sun in fierce quantities has, fortunately for us, diffused greatly by the time it reaches the earth. Of course, the nearer you are to the equator, the stronger and more intense the rays of the sun will be. In the equatorial regions the cry is for cooling, not warming! Incidentally, solar power can be used for cooling, too, when it is combined with certain refrigeration applications, but that is the subject of another blog post:-)

Time for a swim? Is the water warm enough for you?

Time for a swim? Is the water warm enough for you?

In order to heat something efficiently, and here we are concerned mainly with heating our swimming pools, we need the rays of the sun to concentrate on a solar collector that, as its name suggests, ‘collects’ the heat of the sun. In other words, the solar collector absorbs the sun’s heat and traps it there, so that it can be passed on to what we need heated – in our case, the cold water of our pool.

Here’s an example to illustrate what I mean more clearly by pool solar collector. A car that has been parked in the sun for hours on end becomes unbearably hot because the sun has showered heated on the whole car. Everything inside it, including the air has become very hot, too, as the heat has transferred to them as well. Or to look at it from another perspective, the car has absorbed and held on to the solar heat while simultaneously transferring it to all the things inside it.

This is how the solar collector for your pool works too, but instead of air and seats getting heated there is water. The water is pumped into the pool solar collector by the pool pump where it is warmed up a few degrees and then it passes out the other side making way for more cold water as it flows back into the pool. This process continues all day long with the pool water circulating through the solar collector and back to the pool,  getting warmer and warmer.

In its most basic form, the pool solar collector  can consist of a large box which you need to paint densely black. Inside the box, you need to ’snake’ black PVC pipe back and forth so that they get maximum exposure to the sun. The pool water will pass through these black pipes to be heated. The box must be covered with a glass cover to trap heat inside the box – much like the heated car we talked about earlier.

You simply use your pool pump that already circulates water from the pool through the filter before returning it to the pool.  You need to tie into the pool’s return line after filtration has taken place to divert it through a solar collector and then back to the pool.

If you attach an automatic thermostat to your solar pool heat system, then it will switch the system on when the water cools down below your desired temperature and it switches it off again when it reaches the heat you want. You do not have to do anything, the system can be made to work for you.

Taking advantage of the sun’s energy to heat a swimming pool makes great economic sense and brings joy to the hearts of those of us who love swimming cannot bear swimming in cold water.  It’s an affordable way to solar pool heat using swimming pool solar panels which you can make yourself and slot into your existing pool filtering system.

Swimming pool solar heating uses the sun to heat the pool water. Natural gas and electricity have traditionally been the main sources of power for heating swimming pools. Of course, gas and electricity  are expensive and the price for using them is steep with high monthly utility bills acting as a constant reminder. Not so with solar pool heat. You pay the initial outlay and installation costs to begin with and that’s it – no monthly pool heating costs to have to worry about.

Professionally installed swimming pool solar heating systems range in price from $3000 to $8000 give or take. The cost will depend on the size of the pool you want to heat. Even those pools that only require solar heating in the cooler months – mid-fall through winter to mid-spring ot there abouts – will pay for themselves in a few short years. Naturally, if you heat your pool throughout the year, that break-even time will much shorter.

The Basics of How Swimming Pool Solar Heating Systems Work

A solar pool heat system works on a very simple principle.

  • The pool water is heated in special solar water collectors. These solar water collectors must be strategically positioned in an area that receives a lot of direct sunlight daily.
  • The swimming pool water pump is used to pump the water from the pool into the solar water collector,where it is warmed, and then brings the now warmed water back into the pool again. This cycle continues all day long or until your pool has reached the desired temperature.
  • A solar water collector is a solar panel that gets hot when exposed to the sun. The water running through the collector is warmed by the heat that  the collector has absorbed from the sun.

Of course, anything that is powered by solar energy is dependent on sunlight for it to be able to work.  With swimming pool solar heating systems, it is no different. They need direct sunlight to work effectively. That being said, innovations in solar energy technology have changed this equation slightly because systems are being developed that can concentrate the weakest of sunrays into usable solar power.  Of course, in places that get a lot of  sunny weather throughout the year, solar pool heat will do extremely well in all seasons. In places where rainy or snowy weather predominates in winter, they will benefit mostly from an extended swimming season into spring and fall.

There are several different swimming pool solar accessories on the market these days that can be used in combination with the solar heating systems. Solar pool covers, for example, are useful because they help the pool retain its warmth. Uncovered swimming pools lose heat during the cool nights. A solar pool cover helps to trap the heat in the pool. During the cool hours of the night or on rainy days it will prevent heat dissipation. If you keep the cover on during the day when the pool is not in use, the solar cover also increases the water temperature. Solar pool covers attract the sun, get hot, and transfer the heat to the pool water.
