Features and specification:


The collector:

Flat Plate Solar Collector

HOPE flat plate solar thermal collector is suitable for residential or commercial solar water heating projects. The selective coated aluminum absorber sheet absorbs up to 95% of available sunlight converting into usable heat.

1. Glass: Toughened low-iron glass (glazing) protects the absorber from the outside environment while allowing through ≥91% of sunlight.

2. Absorber: A thin sheet of aluminum or copper is coated with a highly selective BLUETEC OR TINOX sputtering coating that is extremely efficient at absorbing sunlight and converting it into usable heat. The aluminum sheet is ultrasonically welded to the copper riser pipes.

3. Insulation: The insulation helps reduce heat loss from the sides and back of the collector. High-density polyurethane and glass wool are chosen by VISION company to greatly reduce weight and heat lost of the collector.

4. Riser & Header Pipe: The header and riser pipes are brazed together to form a harp shaped heat exchanger that the solar system water or fluid circulates through. The absorber sheet is ultrasonically welded to the riser pipes, thus transfers heat to the water or heat transfer fluid.

5. Frame: An aluminum alloy sheet seals the back and frame of the panel and adds to the rigidity of the collector. The rails in the frame are designed for easy mounting attachment.

both ultra sonic and laser welding


The water tank:
 -Pressurized water tank, capacity 100L/150L/200L//250L/300L

1. Inner water tank: Food-grade stainless steel or enamel coated tank keeps the water clean and drinkable, automatic argon-arc welding technics ensures no leakage and long lifespan more than 30 years. VISION hot water tanks have all been immersed in water and tested with 12 bar pressure to ensure no water leakage in high pressure condition.

2. Insulation Layer: High-density polyurethane Integrated-foaming with twice slaking treatment, preserves water temperature constantly.

3. Tank shell: Stainless steel same with inner hot water tank, super in corrosion resistance, much more durable especially to ocean coast weather condition.


System controller(option):
 -Full automatic control system, display the temperature of the water all the time.
 -Automatic start / stop the auxiliary electric heater under the preset timing and temperature
