Thermal performance is obtained by multiplying the collector output for the appropriate application and insolation level by the total gross collector area.

*Collector ratings are derived from the Solar Rating & Certification Corp (SRCC) Document RM-1 and Standard OG-100.

ENGINEERING SPECIFICATIONS

The following shall be the specifications for the solar collectors. Collectors shall be SunEarth SunWise model ________, and shall be of the glazed liquid flat plate type. Collectors shall be tested in conformance with ASHRAE 93-1986, and SRCC 100-81. The collectors also shall be certified by the SRCC and the Florida Solar Energy Center (FSEC).

GENERAL

The dimensions of the collector shall be _________ inches in length, _________ inches in width and 3 ¼ inches in depth. The collector casing shall be an aluminum extrusion (alloy 6063 T5), minimum thickness .060 inch. The casing shall have notched framewalls for ease of plate removal and reinstallation. Sheet metal screwed fasteners shall be stainless steel (18-8 #10). The backsheet shall be aluminum not less than .014 inch thickness. A 1 inch vent plug shall be installed in each of the four corners of the back-sheet to minimize condensation.

GLAZING

The collector glazing shall be one sheet of low iron tempered glass, with a minimum of 1/8 inch thickness (5/32 inch on SC/SP 40), and a minimum transmissivity of 91 percent (89 on SC/SP 40). The glazing shall be thermally isolated from the casing by a continuous EPDM gasket. There shall be a continuous secondary silicone seal between the glass and casing capstrip to minimize moisture from entering the casing.

INSULATION

The insulation shall be foil-faced polyisocyanurate foam sheathing board of a minimum 1 ¼ inch thickness, siliconed in place to the aluminum backsheet. Total thermal resistance shall be a minimum of R-12. The sides and ends of the collector shall be insulated with a minimum of 1 inch foil-faced polyisocyanurate foam sheathing board.

ABSORBER PLATE AND PIPING

The absorber shall consist of a roll-formed copper plate of no less than .008 inch thickness. Risers shall be a minimum of ½ inch O.D. Type M copper tubing on no more than 4 ½ inch centers continuously soldered to the plate utilizing a non-corrosive solder paste with a melting point of 460°F. The risers shall be brazed to 7/8 inch O. D. Type M copper manifolds utilizing a copper phosphorous brazing alloy with no less than 15 percent silver content, and conforming to the American Welding Society’s BCuP-5 classification. EPDM grommets shall isolate the manifold from the aluminum casing. The absorber plate shall be designed for 160 psig maximum operating pressure.

ABSORBER COATING AND PERFORMANCE CURVE

A) Black Chrome (SC Series): The absorber coating shall be black chrome on nickel with a minimum absorptivity of 95 percent and a maximum emissivity of 12 percent. The instantaneous efficiency of the collector shall be a minimum Y-intercept of 0.714 and a slope of no less than -0.7271

B) Moderately Selective Black Paint (SP Series): The absorber coating shall be a moderately-selective black paint with a minimum absorptivity of 94 percent and a maximum emissivity of 56 percent. The instantaneous efficiency of the collector shall have a minimum Y-intercept of 0.682 and a slope of no less than -0.7995 (BTU/ft2hr)/F.
