How much money can you save?

That depends on factors like on the amount of water you use apart from factors like your location and angle of the roof. As for me, I have a 4 collector unit and a storage tank of four 50 gallon druns and I probably save around $600-$700 a year. Its not just about the savings for me, its about the satisfaction of building something like this on my own.

The Theory Behind All DIY Solar Water Heater Projects

The suns energy is immense, but as it traverses over 90 million miles all the energy that reaches the earth is in the form of light or rather ultraviolet light, mind you this can still power the whole world if utilized properly.

Greenhouse effect within Solar water heater?

Heat is given out when low frequency infrared rays are generated from high frequency light.Ultraviolet light can pass through glass but they give out infrared rays when they strike a dark surface. The glass in a solar water heater traps these waves and this is what is called greenhouse effect. Once that happens the molecules start to vibrate and the faster the vibration the hotter it gets. This is how light is converted to heat.

Will the light molecules not cause poisoning?

Good question. Its not advisable to consume water thats the excited by UV light, which is why any good diy solar panel project makes use of collector fluid to produce heat instead of the actual drinking water. Only heat due to molecule movement is transferred to the drinking water which is kept separate.
