SOLINK combines the high efficiency of ground source heat pumps with the advantages of air heat pumps. Silent operation and flexible use on roofs or facades make the collector attractive as an energy source for electricity and heat. SOLINK was specially developed for heat pumps. Coupling with geothermal probes is not necessary due to the high efficiency heat exchange with double use of the roof area. This creates systems with a completely renewable energy supply and low operating costs.

Double use of the roof space and 10 times the heat exchanger surface area.

The area of the roof can usually be used only once for electrcity or heat production. With SOLINK, on the underside of the XL 2 m2 PV module, a special air heat exchanger with a surface area of 20 m2 ensures high power production and simultaneous utilization of the module waste heat. This means that the entire heat requirement is directly covered and the total annual electricity demand is produced. The large surface area heat exchanger makes this possible on a much smaller roof area compared to other PVT collectors.

Silent operation

SOLINK works without the usual fans and an outdoor unit. In comparison to an air source heat pump the outside can be enjoyed in peace.

Highest efficiency without a ground array

So far, a ground array of either bore hole or horizontal pipes had to be laid for low power consumption. SOLINK can do without. In most cases, roof or possibly facade surfaces are sufficient. With similar investment costs, a higher return is given.

7% increase in performance, quality and service life

The large air heat exchanger reduces the module temperature compared to standard PV modules with and without heat pump operation. Approximately 7 - 10% higher output yield and a reduced maximum module temperature lead to a long service life. SOLINK has been tried and tested since the winter of 2016/17 and is based on a precursor development that has been in use since 2014.
