Before eliminating your electricity bill, you should think first of saving your power. We would love to tell you that solar energy was firstly used in cooking by concentrating the sunlight on the surface of a pan absorbing all the heat. This old technique can also be used to heat your water in the 20th century for domestic use or pre-heating treatments in your factory.
A solar collector is a device that collects and/or concentrates heat from the Sun. These devices are primarily used for active solar heating and allow the heating of water for personal use. These collectors are generally mounted on the roof and must be very sturdy as they are exposed to a variety of different weather conditions. The use of these solar collectors provide an alternative for traditional domestic water heating using a water heater, potentially reducing energy costs over time. As well as in domestic settings, a large number of these collectors can be combined in an array and used to generate electricity in solar thermal power plants.
These devices are primarily used for active solar heating and allow the heating of water for use. Also, the solar collector eliminates a big part from your electricity bill with a long lifetime.
