Solar heating solutions for the future

The sun is a climate-friendly energy source that can be harvested for free and used locally. Heating accounts for a large part of the energy consumption in buildings in Northern Europe. Solar collectors transform the energy of the solar rays directly into heat, which is four times more efficient than using solar photovoltaic for heating purposes. Solar collectors can be connected to existing water-borne heating systems.

As of January 1st 2020, it is no longer allowed to use fossil fuels to heat buildings in Norway. The ban will help reduce greenhouse gas emissions and promote the transition to a society where heating solutions are renewable. 


Our products and services

Catch Solar offers solar heating systems that can be adapted to the customer's needs and integrated into the building's architectural design. Our customers are homeowners, owners of commercial real estate, agricultural property or managers of public buildings. We take responsibility for total design or collaborate with renowned subcontractors.
Panels in flexible sizes

Catch Solar has solar collectors that can be adapted to the building's architectural design and integrated into roofs or wall facades.


Catch Solar offers consulting services within hybrid solutions and ensures that you get the most efficient energy solution for your need.


Service and maintenance agreements

Catch Solar monitors our customers system during the operating phase through remote monitoring and can make adjustments for more efficient operations.

Combined solution with electric heating

Solar heating reduces electricity consumption in installations with water-borne heating and electric boilers.

Combined solution with heat pump

For waterborne systems, a combination of solar collectors and heat pumps will increase the effect of the heat pumps and the efficiency of the building's heating system.

Combined solution with district heating

Solar collectors are a good supplement to district heating plants that must be additionally powered by electricity or oil in low load periods in order to be able to supply enough heat to their customers.

Combined solution with biofuel

Solar heating in combination with bioenergy will reduce fuel consumption during the periods solar collectors supply heat.

Charging of energy wells

Solar heating can be used in combination with geothermal heat to charge under-dimensioned energy wells.

Solar powered cooling

Solar heat can be used for both sorptive cooling in ventilation units and as "thermal compressor" in absorption coolers.



Heating demands a large proportion of private energy consumption goes. Solar heating can cover a significant part of the heating requirement in single-family homes, duplex houses or apartment buildings.



For commercial buildings with a large heating or cooling requirement, solar energy will provide a considerable financial gain, in addition to a desired environmental profile.



Solar heating and bioenergy are a good combination to meet the heating needs for grain drying, dairy farming, as well as housing and operating buildings.


Hospitals and care units

Institutions with a significant hot water needs will get good economic and environmental benefit from a solar heating system combined with district heating or other heat sources.

    Solar energy in combination with other heat sources


    There are many advantages to utilizing solar energy for tap water and waterborne heating. The heat can be stored in a hot water tank or in heating wells when the heating requirement is lower than the production. To ensure sufficient energy for heating, it is appropriate to combine solar heat with biofuel, geothermal heat, district heating or electricity from solar cells.
    In the autumn of 2017, the Norwegian Solar Energy Association issued a separate  manual on solar heat,
    which provides a thorough and good introduction to how different heat sources can be combined.


    Catch Solar has a close dialogue with other players in the industry as a member of the Norwegian Solar Energy Association and through the Arena Solklyngen.


    Key terminology in solar energy

    When considering how the heat demand can be covered by solar energy, there are some concepts/terminology that are important to know.


    Investment and payback period

    A rooftop of 100 m² receives solar radiation corresponding to five times as much energy as the house consumes over a year. Solar collectors transform solar rays into heat and provide efficient energy utilization with a high efficiency of 60-80%. A solar heating system has low life cycle costs and a typical payback period of 5-15 years
