Flate Plate collectors(FPC)

Characteristics

• Flat Absorber Plate:

  A flat, dark-colored plate absorbs solar radiation.

• Insulation:

  The plate is enclosed in an insulated box to minimize heat loss.

• Transparent Cover:

  A transparent cover (glass or plastic) allows solar radiation to enter.

• Fluid Passage:

  Fluid (water or glycol mixture) flows through tubes attached to the absorber plate.

Advantages

• Efficient:

  Converts 40-60% of solar radiation into heat

• Cost-effective:

  Lower cost compared to other solar collectors

• Durability:

  Long lifespan (15-20 years).

• Easy Installation:

  Simple and quick installation

• Low Maintenance:

  Minimal maintenance required

Applications

• Water Heating:

  Domestic hot water, industrial processes and swimming pools

• Space Heating:

  Buildings, greenhouses and agricultural drying

• Cooling:

  Solar-powered absorption chillers

• Industrial Processes:

  Food processing, textile and chemical industries.

Evacuated Tubes Collectors (ETC)

Evacuated Tube Collectors (ETCs) are a type of solar thermal collector that uses evacuated glass tubes to absorb solar radiation and heat a fluid.

Characteristics

• Evacuated Glass Tubes:

  Vacuum-insulated tubes minimize heat loss

• Absorber Coating:

  Selective coating on the inner tube absorbs solar radiation

• Heat Pipe:

  A sealed pipe transfers heat to the fluid

• Fluid Passage:

  Fluid flows through a manifold, collecting heat

Advantages

• Higher Efficiency:

  50-70% efficient, surpassing flat plate collectors

• Temperature Range:

  Can achieve temperatures up to 200°C

• Durability:

  Long lifespan (20-30 years).

• Flexibility:

  Suitable for various applications

Applications

• Water Heating:

  Domestic, industrial and commercial

• Space Heating:

  Buildings, greenhouses and agricultural drying

• Cooling:

  Solar-powered absorption chillers

• Industrial Processes:

  Food processing, textile and chemical industries.
