Residential Collectors

  • Evacuated tube collectors- with and without CPC-reflector

    Ritter Group USA distributes mass-produced evacuated tube collectors with and without CPC-reflectors by our internationally well-known production facility Ritter Solar in Dettenhausen (Germany) and Jinan (China). Ritter Solar in Germany is one of the leading global manufacturers of highly efficient evacuated tube collectors with and without CPC-reflectors. Technical know-how, product-development and continued engineering, and self-production facilities are the foundations of international success as an OEM provider (Original Equipment Manufacturer) of solar collectors.

    Application: Residential, service and industrial sector and for public buildings

Production facilities in Germany and China

  • Our evacuated tube collectors are mass-produced products made by our internationally well-known manufacturing facilities Ritter Solar (Dettenhausen, Southern Germany) and Linuo Paradigma (Jinan, China‘s East coast). Fully automated production facilities with state-of-the-art machinery and a production area of approximately 646,000 ft² [60,000 m²] provide us with a sufficient capacity to supply national and international OEM-customers, as well as all Paradigma subsidiaries with a production capacity of about 6,458,000 ft²/ year [600,000 m²/year].

  • our evacuated tube collectors were developed especially for solar water heating and for solar backup heating with German quality standard. Our evacuated tube collectors are mass-produced products made by our internationally well-known manufacturing facilities Ritter Solar in Dettenhausen (Germany) and Linuo Paradigma in Jinan (China). Their outstanding design, professional processing, top quality, high energy yield, and an excellent price/performance ratio make them stand out.

     

Technology

  • High-quality, corrosion-resistant and tested materials ensure smooth operation over a long useful life. The well-known indestructibility of our tubes was confirmed by positive test results in the hailstone test according to DIN EN 12975-2 and the thermal shock test (ITW test report no. 02COL 282). The low pressure loss allows several modules to be connected in series. The aperture area measurements of 1.0, 2.0 and 3.0 m² allow accurate adjustment to water and/or space heating requirements. We also pay careful attention to details which are important for mounting the system: the solar system is delivered with a tentered sun protection sheet to allow commissioning the system even during maximum solar irradiation. Hand straps ensure safe and easy transport and for quick crane mounting.

CPC-reflector


  • To increase the efficiency of evacuated tube collectors, a highly reflective, weather-proof CPC reflector (Compound Parabolic Concentrator) is fitted behind the evacuated tubes. The special, improved geometry of the reflector ensures that direct and diffuse sunlight falls onto the absorber even when the angle of incidence is not ideal. This considerably improves the energy yield.
