Components of swimming pool solar water heater
A homemade solar pool heater generally includes the following equipment:
Most commercial systems include automatic sensors or possiblly a manual valve which diverts water through the collector when the collector temperature is significantly higher in the collector than the pool temperature. Filtered water bypasses the collector if the collector temperature is similar to the pool temperature.
If you are not very used to building your own solar items, I would skip the autmatic control valve. Start will a small project to get anything done at all!
How to get the most from your pool heater?
The most important part of a homemade solar pool heater is its collector. So a perfect positioning of the collector will make a difference. You have to place it either near the pool over the ground or over the roof so that maximum amount of sunlight gets trapped in it. So be careful when installing the collector.
How many collectors do I need for a swimming pool?
If you are doing your own calculations the surface area of your solar collector should equal a minimum of 50%-100% of the surface area of your pool. If you live in a cooler climate or you are in an area with a lot of cloud cover, you may need to increase the ratio between the collector area and the pool surface area. If you add additional collector square footage it will enable you to lengthen your swimming season. You can usually decrease the required collector area by using a pool cover at night to retain heat.
Installation of solar swimming pool heaters
The very first thing you have to do is to arrange the collector. After that, connect your collector to a PV-driven submersible pump. After that connect the solar PV panel to the pumps. The valve should be connected to the pump properly. You need both a filter pump and a heating system pump or one that does both. The filter pump can run for two hours a day in the night time, but the solar collector should run in the daytime.

Add a Solar Pool CoverAdding a solar pool cover decreases the need for heating and lowers the initial cost of a solar heating system. Evaporation of swimming pool water accounts for a whopping 70 percent of a pool's total heat loss. This goes for both indoor and outdoor pools. The best solution to curb this energy and money drain is to invest in a solar pool cover.
There are many type of solar pool covers. A simple "bubble" cover, like this one - similar to bubble packing material - usually can be purchased for less than US$100.
Vinyl covers are more durable and long-lived, but also are more expensive. They are available insulated or uninsulated, and can be integrated with an automated roll-up system to make coverplacement and removal hassle free. Prices range from a few hundred dollars for a basic cover to more than US$1,000 for covers that come with a motorized reel.
