Non-pressure solar collectors are alternatively referred to as low-pressure solar collectors. They function like other solar collectors in the way they harvest solar energy for conversion into heat, nonetheless, they differ from high pressure collectors in that they function in normal or low pressure conditions.

These solar collectors feature less complex design which makes them low cost and suitable for small-scale and domestic and applications. They are popularly utilized in heating water for home use and pools as well as heating up internal spaces.

There are several benefits accrued from using non-pressure solar collectors some of which are discussed herewith:

i. Comparing these solar collectors to high-pressure collectors, you find them more reasonably priced especially for small-scale applications like domestic use. Their less complex design and low part count means their manufacturing cost is lower.

• Flat Plate Solar Collector
• U Pipe Solar Collector
• 500 LTR Solar Water Heater
• Mini Solar Water Heater
• The non-pressure solar collector absorbs solar radiation via an absorber plate which is designed to take up as much radiation as possible. The design includes construction with highly conductive materials and even selective application of dark coating. Furthermore, a transparent cover enclosing the absorber plate ensures the solar radiation is trapped via a greenhouse effect preventing heat loss.
• The absorbed heat raises the temperature of water or other fluid running through tubes attached to the absorber plate. The water/fluid rises naturally through the collector owing to buoyancy since it becomes less dense as its temperature rises. The hot liquid is then channeled for storage or direct use through a piping system.
• A comprehensive evaluation of the installation site helps in ascertaining its appropriateness for a solar collector. This step considers the orientation of roof, its stability, exposure to sunlight, shading and local regulations.
• Prepare the mounting framework when installing the solar collector on a rooftop or other elevated structure following appropriate procedures. The structure should be solid enough to support the solar collector’s weight.
• Place the solar collector where tilt and orientation will most likely maximize solar exposure throughout the day.
• Using the proper mounting hardware, firmly fasten the solar collector to the mounting framework limiting any movement or instability.
