q-solar: new era in solar energy use: solar air heaters

Coal drying - The large water content of coal (especially brown coal or lignite) is responsible for the low efficiency and high pollution produced by the coal-fired power plants.

Solar Air Preheaters - Until now, heat was generated by burning fossil fuels in cold, ambient air; this process generates large amounts of greenhouse gases. Alternatively, our efficient and inexpensive solar collectors can be used to heat the incoming air before it is used in the burning process.

Economical Calculation - is an essential pre-requisite for any renewable energy project

Our Breakthrough in Solar Energy Technology - we have succeeded in making solar heat cheaper than heat derived from any conventional source and that is used for any size application.

Basic Facts about Solar Radiation - essential information about solar activity, the effects of solar radiation, indirect and direct uses of solar energy and the advantages and disadvantages of solar energy

Solar Water Heaters - hot water of up to 100 degrees Celsius is needed for many of our domestic, industrial and commercial activities. Such temperatures are attainable with flat solar collectors (without concentration of radiation), which are relatively simple to build and are very reliable.

Solar Air Heaters - almost all of the energy we use in industry, agriculture and at home is heat or was generated from heat. Mechanical energy and electricity are also produced through the transition of much larger quantities of heat from a heat source to a heat sink.

Solar Mechanical Energy - Mechanical energy can be obtained from solar energy in a few different ways. We detail here the "solar tower" system for which we have an improved version of solar collector.

Installation of Solar Air Heaters - for places at latitudes greater than about 35 degrees, where the sun is low on the winter sky, you should install the solar air heater vertically, on a wall which is oriented towards the Equator (towards the South in the Northern Hemisphere and towards the North in the Southern Hemisphere).

Economical Aspects - solar energy devices are designed to save money for their owners by reducing fossil fuel energy bills. As very few solar energy products on today's market actually do that, we urge prospective buyers to choose carefully, so that they do not end up losing money. Appropriate decisions can be made only after doing an economical calculation.

Environmentally Friendly - our products are environmentally friendly for many reasons, find out why...

Un-economical Technology Aquisition - This can help interested manufacturers avoid costly mistakes

Glossary - the A-Z of solar energy, units and prefixes

Environmental Impact - there are three main aspects relating to the environmental impact of our society: additional heat, greenhouse gases and heavy metals.
