Low cost solar collector

Low cost solar collector

FKE is the new low cost solar panel: it's compact and economic , Made of high quality materials and cutting edge technology.

The FKE solar panel has a harp absorber with 4 connections. The hydraulic system makes it possible to connect five collectors in one row.

The accurate design and the technology of the materials used allow the FKE manifold to achieve high yields even in case of poor lighting.
FKE is certified Solar Keymark and this is a guarantee of quality for our customers.

FKE solar panels

FKE solar panel that absorbs much 

The heart of the compact solar panel is the absorber harp that achieves high yields even in poor lighting, as in the case of the winter months.

The absorbers are manufactured with a special welding machine which ensures a resistant splice and of large surface area between the tube and foil allowing a good transfer of heat.

The use of a single material in the absorber prevents corrosion and thermal deformation.


Connections flexible couplings

The solar panel is easy to install

Il Solar collector economic FKE thanks to its flexible couplings can be installed with ease.

The connections between the collectors with flexible hydraulic compensators are very simple and economical since they require little manpower and less piping for the connections.

They can withstand strong stresses due, eg., To the foundations or movements of temperature and pressure fluctuations.

E 'can connect the manifolds and on the right side than on the left side,
and series you can install up to 5 collectors.

The solar panel FKE can be installed on a flat roof or tile with ease.



FKE laser welding

A powerful and durable structure

The innovative laser welding technology fuses the aluminum absorber plate to the copper hydraulic module. In this way the collector has a perfect and effective weld. 
A good weld means better heat transfer.

The aluminum frame and the high strength of the glass seal EPDM rubber give the panel a high reliability in time against hail, snow and rain infiltration.

FKE is a technologically advanced panel and studied in every little detail.

1- copper pipe with harp geometry
2- perimeter gasket high strength
3- Heat insulation (20mm sides 30mm back)
4- highly selective absorber
5- High strength aluminum frame
6- solar glass of 3,2mm
7- stress resistant connections


solar panel FKE with pellets

The perfect combination: solar thermal and pellet

The FKE solar panel can be combined with any generator and integrates perfectly with pellet stoves and boilers. These two technologies combined allow less expense and greater energy independence.

In winter: the solar system makes a thermal contribution to the boiler reducing its operation. In summer: the solar system produces domestic hot water avoiding the ignition of the boiler. Result:

  • Lower consumption
  • Better use of the boiler
  • Greater freedom for the customer

Solar thermal pellet schemeExample of solar panel installation

FKE is simple to install and can be integrated with traditional systems and with those of the latest generation Rossato Group.

In this example, the solar thermal system is dedicated to production of domestic hot water. Solar panels give off heat to double coil storage tank.

The pellet boiler feeds the heating system with radiators and if necessary integrates the storage of domestic hot water. This plant solution offers the integration of several renewable sources in heating and in the production of domestic hot water, with significant energy savings.
