Frequently Asked Questions

What is a solar vacuum tube?

A solar vacuum tube is a high-efficiency solar thermal collector made of double-layer borosilicate glass with a vacuum between layers to minimize heat loss. It absorbs solar energy to heat water or fluid for domestic or industrial use.

How do heat pipe solar collectors work?

Heat pipe collectors use sealed copper pipes filled with a small amount of fluid. When heated by the sun, the fluid evaporates and rises to the top, transferring heat to a manifold where it heats water. The cooled fluid returns by gravity, creating a continuous cycle.

Are your solar brackets corrosion-resistant?

Yes, our solar mounting brackets are made from high-grade materials with anti-corrosion treatment, ensuring long-term durability even in harsh weather conditions.

Do you offer OEM services?

Yes, Suneco Solar provides OEM and ODM services for solar vacuum tubes, collectors, and components. We support custom branding and packaging for global partners.
