Solar vacuum tube collector efficiency?
The thermal efficiency of vacuum tube collector is between 85-93.5%;The thermal efficiency of flat plate solar collector is 45-55%; the product structure, quality and environmental conditions are different.Data source network, for reference only;Hope to help you want to know the answer!
2, the inner diameter of 340 buckets per meter 180 pounds (1.7*1.7*3.14*10=90.76 liters) 360 the diameter of about 200 pounds3, solar thermal efficiency may depend on the strength of the sun
General 58 of the pipe diameter of the inner tube of 37; about 6.3 kg of water (about 0.235*0.235*3.14*18=3.12 liters) of about 6 pounds of about 1500 pounds (47) of about 3.5 pounds (about 1800 pounds) of about 4747 pounds (about $1600)
