A solar water heater panel is usually contemplated by those thinking of reducing their energy bills.
The operation of a solar water heater system is simple. During the day the solar panel collects and stores energy from the sun. In tropical environments, the average number of suitable daylight hours could be 6-8 hours.
In colder environments, it could be a lot less. Regardless, any energy collected is used to heat the water in the tank. Most singularly designed solar heater panels don’t bother to store the excess energy. As a result, any extra energy produced is loss throughout the day.
Dedicated Solar Water Heating Systems Versus Photovoltaics
Although a many home owners have gravitated towards installing a solar water heater panel in their home, some have decided to install a solar photovoltaics (i.e., PV) system instead. The reason is that although it will save the homeowner a great deal of money, a solar water heater panel will heat water and nothing else.
On the other hand, a solar PV system will heat water as well as provide electrical energy to fill your other electrical needs as well. In fact, depending on the city in which you live, you may be able to sell the excess energy generated by your PV system to your local utility. So, instead of merely saving money, you actually are making money with your system.
Here’s how you can build your own solar water heater panel – (for advanced handymen).
