What is Solar
Solar energy is the cleanest and most inexhaustible of all known energy sources. Solar radiation is the heat, light and other radiation that is emitted from the sun. Solar radiation contains huge amounts of energy and is responsible for almost all the natural processes on earth. The suns energy, although plentiful, has been hard to directly harness until recently. Solar Energy can be classified... Read More >>
How does using solar help the environment
Currently Sidite solar collectors are reducing CO2 emissions by more than 13,000 tonnes / 28.6million pounds per year, with collectors installed in the UK, USA, New Zealand, Germany, France, Sweden, Italy, Hungary, Portugal, Jordan, Lebanon, Australia, Canada, Mexico and many other locations. (One metric tonne = 2200 pounds) There has been a great deal of information in the media over the past... Read More >>
What is an Evacuated Tube
Evacuated tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Evacuated tubes have already been used for years in Germany, Canada, China and the UK. There are several types of evacuated tubes in use in the solar industry. Sidite collectors use the most common "twin-glass tube". This type of tube is chosen for its reliability... Read More >>
What is a Heat Pipe
Heat pipes might seem like a new concept, but you are probably using them everyday and don't even know it. Laptop computers often using small heat pipes to conduct heat away from the CPU, and air-conditioning system commonly use heat pipes for heat conduction. The principle behind heat pipe's operation is actually very simple. Structure and Principle ... Read More >>

How strong is the solar radiation (insolation) in my area
What is solar insolation? The amount of electromagnetic energy (solar radiation) incident on the surface of the earth. Basically that means how much sunlight is shining down on us. Why is knowing the insolation level useful? By knowing the insolation levels of a particular region we can determine the size of solar collector that is required. An area with poor insolation levels will need a lar... Read More >>
What size collector do I need
When determining what size collector you need, you must consider two key factors: insolation level and energy requirements. Energy requirement will usually take into consideration the volume of water and rise in temperature required. Once you know these factors you can determine the size collector you require. The bigger the collector you have, the more hot water, but you should make an economical... Read More >>

How much energy can a solar collector produce
Using this energy calculator you may determine how much energy an Sidite solar collector will produce each day/month/year. The way you utilize this energy is up to you. You can heat water for showering and washing clothes, or central heat a building. In fact one integrated system can complete both these functions. You can also use these values to help you calculate how much energy you can save... Read More >>
I have more unanswered questions! Please visit the Frequently Asked Questions page
1. Is solar water heating a viable alternative to gas or electricity? Solar should not be seen as a alternative to gas or electricity, but rather a supplement. Solar cannot totally replace the need for gas or electric heating as there are sometimes days when there is little sunlight. When averaged over a year, a correctly sized solar system can provide 60%-70% of a household's hot water needs. Pr... Read More >>
