Are evacuated tube solar thermal collectors more efficient?

Evacuated tube solar thermal collectors are more efficient than flat panel type collector owing to their construction.

What is a Navitron evacuated tube solar collector?

Navitron 20’s combined to give 14 kWh/day output peak output during the summer months. Freestanding collector designed for use with flat roof applications. Welcome to the Navitron Evacuated Tube Solar Collector!

What are solar irradiation tubes made of?

The tubes are made of borosilicate glass, which is strong and has a high transmittance for solar irradiation. In order to reduce the convection heat lost, the glass tubes are evacuated to vacuum pressure or less than 10-3 Pa. Stable vacuum seals are ensured by using a patented technique employing high heat and pressure.

How much water can a 30 tube collector hold?

The water volume capacity of the header pipe is less than 1.5 litres for the 30 tube collector, thus allowing fast heating during even overcast conditions. This is important for areas with lower solar irradiation or overcast conditions, as the heat from the manifold can be quickly harnessed, then held in the storage tank.

Can Navitron install a solar collector?

As a professional solar installer, Navitron expects that you will know how to correctly install the collector to ensure efficient performance and system reliability. We can provide you some technical advice as required, but we may not be that familiar with the specifics of your region.

How many blocks are in a 30 tube collector?

Each block is 73cm long, so 4 are used for a 20 tube collector, 6 in a 30 tube collector. The mold shape fits tightly around the header pipe and tube port shape to ensure maximum insulation performance. Each collector is supplied with a stainless steel adjustable width frame.
