Fresh air into your home with solar energy

Healthy indoor climate

Continuous fresh air exchange supports well-being, helps improve sleep quality, and reduces the risk of moisture build-up and mould growth.

Low energy costs

Sol Fresh uses solar energy for ventilation and additional heating, helping reduce reliance on conventional heating and keeping running costs low.

Longer building lifespan

Protects structures from moisture damage, prevents mold, and reduces the need for costly repairs.

Sol Navitas creates solar-powered ventilation solutions that bring fresh air into buildings, help remove excess moisture, and use solar energy to preheat incoming air and support ventilation.

Poor air exchange damages both the indoor climate and the building

When air does not move enough, moisture, odours and used air can build up indoors. Over time, this can lead to condensation, musty smells, conditions that favour mould growth, and moisture damage.

The problem is especially common in summer houses, rarely used buildings and rooms where ventilation does not work well enough.

Moisture often builds up during the summer

In autumn, solar-supported ventilation helps remove this moisture from the building by bringing in fresh air and additional warmth from the sun.

This problem is especially common in summer houses, rarely used buildings and spaces with insufficient ventilation.

Solar energy supports ventilation

Sol Navitas systems use solar energy to bring fresh air indoors, support ventilation and reduce the problem of cold incoming air.

Solar air heating preheats the incoming air and, during cooler periods, can provide a significant amount of additional warmth to the building.

If excess moisture has built up in the building, continuous air exchange helps gradually remove it and keep the indoor climate more stable.

Ventilation does not have to be just an energy cost

Standard ventilation tries to reduce heat loss. Solar-powered ventilation does something more — it uses the sun to bring fresh air into the building together with additional warmth.

In sunny conditions, the question is not only how little energy ventilation uses, but also how much solar heat can be brought into the building through the ventilation system.

Healthy indoor relative humidity is often between 40–60%


When humidity stays too high, the risk of condensation, mould and moisture damage increases.

Ventilation can account for a significant share of a building’s heat loss


Incoming air preheated by the sun helps reduce the energy cost related to ventilation.

With our ventilation equipment, you can create a better indoor climate and achieve lower energy consumption. We offer a wide range of products for this very purpose. In order to create a comprehensive energy solution and maximise the use of solar energy, we will work with you to design a plan that will work as efficiently as possible in that particular building. It is possible to create a comprehensive energy solution for your building, both at the design stage and later, by making existing systems more energy efficient.
