Its life-time may be15 years and has noticeable benefit to economy, environment, society. Now, it has been used in many companies in some cities.

Note: Absorb area is the part of the collector that actively absorbs the light rays. For solar tubes this is defined
as the cross-sectional area of the inner tube(selective coated)measured using the outside diameter.(e.g.0.047m
x1.72m=0.08m2 ) |
