SOLAR INDUSTRIES GUIDE SPECIFICATIONS
Contractor to supply and install collector’s nominal size (4' x 12', 4' x 10', 4' x 8') with overall frontal area of (47.3, 39.3, 31.4) square feet each. Collectors shall be fabricated from a propylene copolymer with stabilizer combination providing long-term resistance to heat and light. The weight of collector when filled with water shall be no more the 1.3 pounds per square foot of frontal area. The collector shall be capable of withstanding an internal static pressure of 85 PSI at operating temperature and shall be resistant to corrosion, freezing, and internal scale accumulation.
Collectors shall be capable of thermal performances of at least 85% efficiency when inlet fluid temperature equals ambient temperature and be capable of collecting solar energy when the inlet fluid temperature exceeds the ambient temperature by 60F with 250 BTU per square foot per hour.
Pressure head shall be capable loss of a single panel must not exceed 0.30 feet water at recommended flow rate. Collector mounting center shall be 51 inches.
Collector mounting center shall consist of 18-8 chromium-nickel stainless steel mounting hardware with two continuous transverse straps having black polypropylene coating. Transverse straps shall be fastened with 18-8 chromium-nickel stainless band.
Water connections shall be made with hose sections extruded from EPDM (ethylene-propylene-diene-terpolymer) 70 durometer minimum hardness. Hose clamps shall be all stainless worm gear type with 18-8 chromium-nickel stainless band.
The collectors shall meet or exceed the minimum standards established by the Florida Solar Energy Center, SRCC, and other applicable nationally recognized standards, and shall be manufactured in the U.S.A.
