Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.

Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

When you decide to convert your main power source over to solar power you will need to make some adjustments to the appliances that carry the power source. When you use solar power to heat your water you may find that you will need to purchase a solar powered water heater in order to do that.

You may be able to make adjustments to your existing one but what ever steps you take to turn it into solar power it will be worth it.

There are several different ways to heat your water using solar power. You can even make your own solar power source. The water runs through pipes before it enters your home. Heating water using solar power will occur before the water gets into your home as it passes by the solar source that attracted the light.

You may also have a tank to store the water in that can heat the water up. In order to heat your water successfully you will need to have both a solar collector and a storage tank.
A flat plate collector is the most common collector. It is designed to be a thin, flat rectangular box that has a see through cover and it can carry fluid to be heated. This fluid could be the water or it may be a solution, such as antifreeze that will prevent the water from freezing. Next the water moves through the tubes to an absorber plate. This plate is painted black to attract and absorb the heat from the sun. When the collector gets hot, it will heat the fluid that passes through the tubes.

As the water passes through the tubes it goes into the storage tank. The storage tank holds the heated water. It is usually well insulated so the water will stay warm longer. Then the water flows into the home on demand.
Solar water heating systems are divided into two groups: Active and passive. When the heating systems are active, that means that they rely on the pumps or other mechanical device that can move the water between the flat plate collector and the storage tank.

Both ways are logical and may be more of a choice of preference for you. Another thought that you need to consider is that if your flat plate collector and your storage tank is not angled right it may be hard for the gravity to feed the liquid through.

Heating water using solar power is very affordable and can be installed with minimal effort. Choosing to heat your water using solar power is a wise choice and a first step in making a choice to help preserve our environment.

We know how easy it is to use solar power to do a lot of things, including heating our water.
  1. Active is the most common because it is quicker and more efficient.
  2. The passive system relies on gravity to feed the water from the flat plate collector to the storage tank. This may be slow at times and may not be sufficient enough to keep up with the demand.
