Leading efficiency - tested and verified

We produce the world’s most efficient flat plate collectors for large scale solar thermal applications such as district heating or industrial process heating. Our collectors are 10–20% more efficient than most high quality collectors in the market. This efficiency will either supply more energy from an equal amount of installed collectors – or allow the required amount of energy to be harvested by using fewer collectors and requiring less land or roof space. Our leading efficiency has been independently tested and verified by several international institutions.

10–20% more efficient than most high quality collectors in the market.

Savosolar’s collectors perform better than any other known flat plate collector for off-centre incident irradiation. When the sun shines with +/- 50 degrees deviation from perpendicular to the collector surface, our collectors still maintain up to 98% of their energy production efficiency. This allows our customers to benefit from solar heat from the early morning until late evening, even during early spring and late autumn days.

Savosolar’s collectors have internal connection hoses which minimise thermal losses in the connections. Due to the connection hoses being an integrated part of the collectors, the collectors have been performance tested with the connection hoses attached. This means that our efficiency results include thermal losses from connections.

In our award winning absorbers, the flow is always laminar. Therefore, the collectors maintain their measured efficiency levels also at low flow rates in short collector rows or during cloudy days – thereby ensuring the performance remains high on the days it matters the most.

High performance also on days with less sunshine

Our collectors are available with single glazing, or double glazing. The double glazing significantly increases the insulation of the glass side of the panels, where most heat is lost. This solution increases the amount of production hours during the darker days of the year and guarantees the stability of the performance during the entire lifetime of the collector.

Savosolar’s collectors have self-supportive frames which have been tested to withstand higher loads than any other known collector – enabling it to manage fierce wind loads which may occur in coastal areas or on high roofs.

The collectors are all equipped with a low iron safety glass, which has received an antireflective treatment by etching. The etching changes the surface structure of the glass and thereby guarantees that the antireflective performance doesn’t degrade from weathering over the years.

Our collectors have been Solar Keymark certified after testing at SPF in Switzerland and is the only collector known to have received PED module A2 certification according to the EU’s regulation on pressure equipment.
