Flat plate solar collectors are the most common solar collector for solar water-heating systems in homes and solar space heating. Our flat plate solar collectors are an insulated metal box with a glass or plastic cover (called the glazing) and a dark-colored absorber plate. These collectors can heat liquid or air. It takes total area of 1.5 square meters or 2 square meters for installation.

Evacuated solar tube collectors can achieve extremely high temperatures, making them more appropriate for cooling applications and commercial and industrial application.

Features:

• High heat effectiveness: higher than all - glass evacuated solar collector tube by 15%
• Heat pipe conduction: Successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand
• Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season
• Low thermal capacity makes the tube start up quickly
• Energy output within only 2 minutes of sunshine
• Insulation temperature can reach 250o C, average heat efficiency can still be more than 50%; even under -50oC
• High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube has higher heat output in cloudy weather and in moist areas, especially in winter
• Solar collecting plate is sealed inside a high quality borosilicate glass tube with 5 x 10 - 3 pa of vacuum, to stop corrosion; even in moist conditions.
