Vacuum solar panels

Design and construction features unique

Solar panels T12-CPC have been designed with the utmost attention to every small detail and made with quality materials that ensure a long service life of the solar system.

Against bad weather and hailhave been optimized in the outer stainless steel and glass with increased thickness of the 13% compared to standard models.

Evacuated tubes are made of a special alloy copper - nickel which gives the collector an excellent rexistence even at long Exposurethe addition of the 250 ° without risk of corrosion and deterioration.

Before being put on the market, each collector is subjected to strict quality controls and physical endurance.


Vacuum solar panelsHow are the solar collectors?

The solar thermal vacuum T12-CPC consist of a double-glazed and work on the principle of the thermos, the gap between the two glass retains heat even when outside temperatures are very low.

The cylindrical tubes, together with the CPC reflector capture the sun's rays from different angles (even those that are usually lost with flat plate collectors) and enable high yield, even in the afternoon and facing unfavorable.

Reflector sunlight

They capture the sun's rays slanting

Under the vacuum tube is placed in a special mirror parabolic reflectors (CPC) that embraces the manifold.

This sensor light can also capture the sun's rays reflected on the oblique vacuum tube, while maintaining the original heat and minimizing heat losses.

The riflettitore is made with special materials capable of providing excellent yields of the diffused light.

By the construction of the reflector related to those of the vacuum tube, the solar thermal system increases exponentially performance even when the sky is overcast and low light.

Fittings and connections located at the bottom

The collector positioned at the bottom makes the difference

The solar panel vacuum tube T12-CPC differs from similar models mainly for the positioning of the manifold and the connections in the lower part of the panel, rather than at the top.

This technical device ensures a higher yield and a higher resistance and stability over time of the entire system.

Read below all the advantages that lead the manifolds in low places


No leakage of glycolAnti corrosion

The special configuration of the CPC-T12 protects the collector, especially in the summer stagnation in the early stages of the plant.

In traditional systems: The antifreeze evaporates slowly through the connections in high places: the antifreeze decomposition, attacks and damages the tube collector.
T12-CPCThe connections are at the bottom in the collector-T12 CPC favor the rapid expulsion of the glycol, increasing durability and preserving the collector and its components from the risk of corrosion.


Anti-condensation system

No condensation

The presence of condensation in the solar panels is a normal phenomenon quite frequently, mainly due to continuous temperature ranges.

In traditional systems: The condensate accumulates in the bottom and can be frozen by blowing the glass tube.

T12-CPC: The water can not accumulate, but immediately comes out of the tube to avoid any damage.


Antidispersioni thermal

Dispersions minimized

In a solar thermal plant is very important that the heat is not lost.

In traditional systems: The tubes open upwards allow hot air to escape in the pipes, thus causing heat losses.

T12-CPC: The tubes of the T12 CPC, on the contrary, are closed at the top and retain the stored heat, avoiding dispersions and thus improving the yield of the system.


Savings with solar thermal vacuum

Saving with solar thermal vacuum

By integrating the solar panels T12-CPC to a system for heating can save you on average every year until 30 - 50% energy than systems with flat plate collector of the same size.

The yield of the system is particularly evident in the winter months
and in the presence of low temperatures.
