Product - RITTER Evacuated Solar Panel

Performance
A high performing solar Heating panel not only produces more energy throughout the year but also takes up less roof space!

• Vacuum insulation
  The high level of vacuum makes the solar panels light reactive rather than heat reactive. This allows the solar heating panel to work even on cold and windy days giving exceptional 'year round' and 'all weather' performance.
  
• Reflector
  The RITTER Evacuated Solar Panel is unique in having an internal silver mirror reflector within the glass tubes concentrating the captured radiation into the absorber. This effectively means that theRITTER ETC 16 panel can absorb the same amount of solar irradiation as a larger solar heating panel with a traditional design.
  
• Absorber
  A 360° glass absorber allows the effective capture of a wide range of wavelengths of radiation and makes the panel virtually independent of the angle of the sun. The highly Aluxide® selective coating has an absorption of =95%±1% and an emittance of <=5%.

Manufacturer - RITTER

RITTER is a multinational company based in Germany with a turnover of nearly €2 billion and 16,800 employees based around the globe. The Company was founded over 120 years ago by Otto RITTER and Carl Zeiss and has built a reputation of innovation and manufacturing excellence.

RITTER offers a 10 year guarantee on the vacuum quality of their solar tubes and a 5 year guarantee on the solar heating panel as a whole.

Reliability and longevity
Purchasing a solar heating system is a long term investment so it is essential that the solar panels have a long lifespan with a high level of reliability. The RITTER ETC-16 solar panel is designed and manufactured in Germany and provide exceptional reliability and durability providing peace of mind for the user.

• Borosilicate Glass
  The RITTER ETC-16 solar collector tubes are made from borosilicate glass rather than soda glass. This provides them with a much greater level of mechanical strength.
  
• Glass tube design
  The RITTER vacuum tubes have been designed to be made completely of glass. This 100% glass design gives a high stability which is difficult to obtain when multiple materials are sealed together. When different materials are used for sealing, vacuum loss would be at risk, as different materials expand at different rates.
  
• Stagnation temperature
  The overall design, quality of materials used and quality of manufacturing means that the RITTER ETC-16 solar panels can withstand a stagnation temperature of up to 280°C. This makes it one of the hardiest solar panels in the market ensuring long life with a high level of reliability.
