How
it works
- Water, or another heat transfer fluid is slowly pumped through the solar
collector and is heated by the sun.
- Hot water is typically used to heat a building, provide domestic
hot water, or provide industrial process heat.
- An insulated water storage tank is typically
used to store energy for night use or cloudy days.
About
the technology
- Collector is made of a glass vacuum tube with
an aluminum cylinder inside.
- Light passes through the first layer of glass,
through the vacuum, and is then absorbed upon a specialized coating on
the second layer of glass, converting the solar energy into heat
energy.
- Heat is then conducted from the second layer of glass, to the aluminum cylinder.
- Inside the aluminum cylinder is a copper pipe.
Water flows through the copper pipe absorbing thermal energy.
- Behind
the glass tube is a compound parabolic concentrating (CPC) reflector, an
advanced mirror that concentrates light onto the absorber surface.
- This
configuration offers extremely high gross collector efficiency
in a compact,
non-tracking solar thermal collector.
- Highly sustainable: Copper, aluminum, and glass
are the primary raw materials used in construction.
All recyclable and abundant natural resources.
