Compact flat plate solar water heater system

On-roof solar hot water heating system
Flat plate solar energy Composition of system:
The complete system consists of the flat plate solar collector, tank, demountable stand, and connection element.
General Speciation of Collector
Flat plate solar collector:
1. Bottom plate: Consists of a frame composed of either aluminum thickness or Galvanized steel at 0.4 mm.
2. External Frame: Protects the collector and reforms all collector parts made from hard aluminum with a thickness of 1.2 mm and height of 100 mm; This is very essential to resist surface corrosion.
3. Insulations: Composed of rock wool, insulation prevents heat loss from the collector to exterior with a total thickness of 100mm inside of the frame of depth 50mm.
4. Frame Insulation: Composed of rock wool, frame insulation prevents the loss of heat from the collector frame; Has a thickness of 20 mm.
5. Panel: Internal surface which converts sun light to heat throughout the water pipes. These pipes are coated with black paint and special chemicals for high efficiency heat absorption. The panel is composed of copper or aluminum and coated throughout for efficient absorption.
6. Rubber Sealing Gasket: Cuts the connection between the panel collector pipes and the frame to prevent the loss of heat transferred from the collector pipes to the frame, prevents water leakages into the internal side of the collector, and prevents the heat losses that occur due to the air gap.
7. Glass Rubber Seal: Rubber seal placed all around the glass, enabling it to stay firm between the frame and the glass lath. It prevents heat losses and leakage of water into the collector. They are used as single piece glass rubber seals without any point.
8. Collector Pipes: Made of copper or aluminum, enables the transfer of heat created on the panel. The outlet diameter of the heat transfer depends on required specification.
9. Top Cover: Glass surface to conduct solar light into internal parts of the collector. It serves the function to prevent the possible heat losses and leakages.

The surface is composed of plain, tempered, and prismatic glasses. Glasses maintain a low iron oxide content with high conductivity.
