Evacuated solar collector tubes perform very well in overcast weather conditions and low temperatures as well
Features:1) High heat effectiveness: higher than all glass evacuated solar collector tubeby 15%2) heat pipes conduction: successfully prevents the defects of tube breakage and lowpower output caused by water fouling and deposits or dust and sand3) Prevents the tube from being easily broken caused by volume expansion whenwater freezes in the frigid season4) Low thermal capacity makes the tube start up quickly5) Energy output within only 2 minutes of sunshine6) Insulation temperature can reach 250deg;C, average heat efficiency can still bemore than 50%; even under -50deg;C7) High efficient selective absorptive coatings and vacuum heat insulation technologyensure the tube has higher heat output in cloudy weather and in moist areas,especially in winter8) Solar collecting plate is sealed inside a high quality borosilicate glass tubewith 5 x 10 - 3Pa of vacuum, to stop corrosion; even in moist conditionsMetal-glass evacuated solar collector tube consists of a single glass tube and aflat or curved aluminum plate inside attached to a copper heat pipe.
