The Falbel DeltaTM Model 13 AC solar collector is a 16″ x 121″ solar panel. It has been fully accepted by U.S. Housing and Urban Development Agency and U.S. Department of Energy for solar grants and tax credits, and has successfully passed the National Bureau of Standards 9377 Solar Collector Qualification test, which includes a 30 day, high temperature stagnation period.
This collector is unique in that it optically focuses the sun’s energy on both the front and the rear surfaces of the absorber plate, thereby reducing the area and, more importantly, the cost of this key solar collector component. The absorber plate is coated on both front and rear surfaces with a black selective absorber. Due to its patented, concentrating reflector curve, the Model 13 AC collector can absorb direct and diffuse sunlight over its full aperture through an elevation angle greater than 90° and an azimuth angle of 180° while not requiring sun tracking or movement of any kind throughout the year. It can, therefore, functionally replace any flat plate collector.
TESTIMONIAL: “We are very satisfied with the performance of our solar hot water heater
which has been operating successfully for several years. We never have to purchase heating oil from May to October:

There are no joints in the copper fluid passage internal to the Model 13AC collector housing. This has an important bearing on solar heating system longevity. Most flat plate collectors use copper tube “grid” patterns which have upwards of 18 soldered or brazed joints in the grid, and any leaks that occur will probably at one of these joints. In view of this feature, Optical Energy Technologies Inc. can confidently warrant the fluid passage in its Model 13AC solar collectors for 20 years.
