Swimming pools require heating to bring them to a desired temperature during the swimming season, or to extend the swimming season in any climate, for swimmers to enjoy their pool virtually all year-round.
Solar swimming pool heating technologies first appeared in the 1970s and todays' solar pool heating systems are super-effective and very reliable. Solar pool heating systems have a lifespan of up to 20 to 30 years.
There are many options available in the market to do so, but using the suns' power is much more economical and beneficial. There are numerous advantages of using Solar Power. The potential of solar energy is almost infinite, with declining costs and no fuel and maintenance charges.
It is environmentally friendly, does not lead to significant GHG emissions, and does not lead to health hazards like thermal power.
There is no danger of pollution or other health risks. Solar Energy can be installed very quickly.
Small residential installations can be done in as little as a day. This is much faster compared to the installation of other energy sources.
Heating your swimming pool through solar panels is by far the most cost-effective option. Gas fired units, heat pumps and oil heaters have huge initial installation costs and are expensive to operate and maintain.
Gas and electric pool heaters, have to be replaced every seven to ten years. Electric Immersion heaters do not perform well outdoors, are expensive to install and operate.
All of these heaters require annual maintenance, and possibly repair. Solar pool heating on the other hand is free and recommended by the majority of swimming pool builders.
How do pool solar panels work?
Solar panels can be fitted to the roof of a building, laid on the ground or mounted on plywood or other suitable, purpose built structures.
On the top and bottom of these panels are collector tubes (generally, PVC pipes), which distribute the water, and carry the solar heated water back to the pool.
Water from the pool is channelled through the panels and is heated by the suns' rays.
The water is then returned to the pool by the existing pool pump. Depending on the amount of solar panels to total water volume ratio, temperatures of 22º C to 41º C can be achieved with zero additional power consumption.
It is a very simple yet effective system which has greatly reduced the cost of utilizing solar heat for swimming pools.
Standard pool solar collectors require a bank of panels equivalent to approximately 76% of the surface area of the pool depending on the geographical location.
