The world’s most
efficient solar collector
Jorgensen has partnered with Savosolar to offer the best solar thermal plants in the world. Savosolar builds the world’s most efficient flat-plate solar collector. The benefits for the client are lower energy costs and energy-denser solar fields. It’s that simple. Here is the proof:
In Denmark, which is the biggest market for large-scale solar heating in the world, Savosolar holds the record of energy produced per square meter of solar collector. This record was set at the solar plant in Jelling. The plant managed to produce 4.97 kWh/m2, which is 6% more than the previous record in Denmark.
The record-breaking solar field in Jelling, Denmark.
In Switzerland, all the solar collectors that are eligible for subsidies in Switzerland have been registered. All collectors have almost the same ratio between energy production and area. All except one: The Savosolar collector.
The reason behind these achievements is mainly due to their innovative absorber design, which was recognized at the 2011 Intersolar Industrial Fair. Savosolar won the Innovation Award for its innovative absorber design. Intersolar is the world’s leading solar energy event.
The Savosolar collector is especially designed for large-scale industrial solar installations. For large scale solar thermal plants, solar collectors made especially for large scale applications must be installed.
The Savosolar collectors are 10–20% more efficient than most high-quality collectors on the market. This efficiency will either supply more energy from an equal number of installed collectors or allow the required amount of energy to be harvested by using fewer collectors, thus requiring less land or roof space. Savosolar’s record-breaking efficiency has been independently tested and verified by several international institutions.
The innovative Savosolar absorber design
Savosolar’s collectors perform better than any other known flat-plate collector for off-center incident irradiation. When the sun shines at deviations of +/- 50 degrees from perpendicular to the collector surface, the 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.
Savosolar’s collectors have internal connection hoses that minimize thermal losses in the connections. Since the connection hoses are an integral part of the collectors, the collectors have been performance tested with the connection hoses attached. This means that our efficiency results include heat lost from the connections.
The flow is always laminar in the award-winning absorbers. Therefore, the collectors maintain their measured efficiency levels even at low flow rates in short collector rows or on cloudy days – thereby ensuring the performance remains high on the days it matters the most.
The collectors are available with both single 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-supporting frames tested to withstand higher loads than any other known collector, thus enabling them to withstand fierce wind loads that may occur in coastal areas or on high roofs.
The collectors are all equipped with a low iron safety glass, which has been given an antireflective treatment by etching. The etching changes the surface structure of the glass and thereby guarantees that the antireflective performance does not degrade from weathering over the years.
Savosolar 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 on pressure equipment regulation.
