This is a top-of-the-line solar water heater for all of your hot water needs.

When you decide to convert your main power source over to solar energy you will need to make some adjustments to the appliances that carry the power source.  When you use solar energy 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 energy  power it will be worth it.

There are several different ways to heat your water using solar energy.  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 devices that can move the water between the flat plate collector and the storage tank.  Active solar energy systems are the most common because they are quicker and more efficient.  The passive system relies on gravity to feed the water from the flat plate collector to the storage tank.  This kind of passive system has the advantage that electricity outage and electric pump breakdowns are not issues. This makes passive systems generally more reliable, easier to maintain, and possibly longer lasting than active systems. Passive solar energy water heating  systems are often less expensive than active systems, but are also generally less efficient due to slower water flow rates through the system.This may be slow at times and may not be sufficient enough to keep up with the demand.  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.

Evacuated tube solar collectors can provide useful hot water during all 12 months of the year! As long as the sun is shining, the AMBIENT TEMPERATURE AND CLOUDS ARE IRRELEVANT! These units work with the infrared spectrum and will work great on overcast days or even rainy days.

Heating water by using the energy of 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 the power of  solar energy to do a lot of things, and that includes the  heating of your water.

  1. Solar Energy is one of the best ways to get clean energy . Today the efficieny of solar power is a bit low but with advances in technology, solar cells will become more and more efficient in harnessing the energy of the sun.

  5. to date, solar panels which generate more than 100Watts are still expensive but hopefully they are getting cheaper each day “

  6. i could only wish that solar panels cost only several hundred dollars, i would love to fill my roof with solar panels *.-
