Residential Solar Water Heatingby Admin
Apr 2014

Message: I am doing a project for residential solar water heating  I am looking for information about how much BTU/hr or BTU/day we can expect out of a 4 panel system with 30 tubes each. Our location is Juneau, Alaska and the heating system will be for the radiant heating with an outdoor air source heat pump as back up. Could possibly do domestic hot water heating too if we can get enough btu/hr and supply temp from the solar panels. Let me know what kind of information you have that could help me out. Thank you, Ryan Gorle

Hi Ryan, The SunRain TZ58/1800 30R  which is one collector with 30 solar evacuated tubes the Btu rating per hour is max 7500 btu per hour. For 4 collector system maximum btu per day  from our collectors is 7500 x 4 collectors x  6 hours of light energy available = 180,000 Btu per day. Copy of SRCC rating on our collectors for you to review.  I would suggest you connect to your domestic hot water system to receive the 30% direct federal tax credit. Please send me your home dimension and number of people using domestic hot water daily what size is your existing hot water tank how is that heated. Is you heat pump run by electricity?        Specification  Heating Series  Heat Pipe TZ58/1800-20R Heating Series  Heat Pipe TZ58/1800-30R Number of tubes 20 30 Frame& manifold Aluminum Aluminum Heating type Copper Heat Pipe Copper Heat Pipe Length of Tube 1800mm 1800mm OD of tube 58 mm 58mm ID of tube 50 mm 50mm Glass Thickness 2 mm 2mm Water Capacity 1l(1/4 gallons) 1.5l (1/3 gallons) Weight dry 169lbs 211 lbs Weigh Wet 173 lbs 215lbs Max BTU/HR 5000/hr 7500 BTU/hr Pressure 116 psi 116 psi Glass MaVacuumterial Borosilicate glass Borosilicate glass Vacuum P<5x10 -3 PA P<5x10 -3 PA Frame Included Included Warranty  10  years 10  years   If you can provide me with that information I request we will provide you with a solar simulation report.
