Vertical all-glass vacuum-tube solar collector for non-pressurized systems.

Product Advantages:

1. High-efficiency solar absorption: The arc-shaped glass vacuum tubes have a selective absorbing coating that captures the full solar spectrum and converts it to heat with high efficiency. The vacuum between the glass tubes greatly reduces heat loss.

2. Excellent weather resistance: Withstands wind, hail, dust and temperature extremes.

3. Long service life: Vacuum tubes can be replaced individually, reducing maintenance cost.

4. Wide application: Widely used in residential and commercial solar water heating systems.

5. Cost-effective: High performance at an affordable price.
