Solar Pool Heater
Our very simple, DIY solar pool heater uses a photovoltaic (PV) module to provide free power when the sun shines, which is when you want the pump to run. It also uses a small, DC submersible pump and some black landscaping tubing.
You can also use the existing pump to run your DIY system, but be aware of the extra cost for electricity to run the pump. If you place your tubing on a roof, you can add a lot of strain to the existing pump. This could shorten the life of the pump and could also make a rather large increase in the amount of electricity used by the pump. As well, you want the solar pool heater to run during the daylight hours. This is often when electricity cost the most and may not coincide with your optimal pump running hours. A PV panel and small submersible pump could pay for itself in just one season.
