Delta Centre of Excellence Test
Carried out independent tests of the top selling solar air collectors on the market and compared them with the SolarVenti products. Test results show that there is a huge difference between the performance capacities of the solar air collectors.
Date of test report:
September 5, 2013
Tested models:
• SolarVenti SV14
• Scansun Model XL27
• Grammer Twinsolar 1,3
Test Results:
The maximum temperature rise of the air for all models is between 15.3° to 25.8° C. Grammer has the highest and Scansun the lowest temperature rise.
The SolarVenti model is in the middle. In contrast, the SolarVenti is the outright test winner if you look at the air change. The SolarVenti model has a 60-80% higher air change compared with both competitors.
Date of test report:
September 2, 2013
Tested models:
• SolarVenti SV7
• Suncore 1m2
• Maxivent 1000
Test Results:
First place for the overall performance capacity in Watts / m2 goes to the SolarVenti. The Swedish competitor Maxivent achieve a good 2nd place. If you measure the air change, the SolarVenti is the clear test winner again.
Date of test report:
August 21, 2013
Tested models:
• SolarVenti SV7
• Sol Fresh 30
• SPAH 3
Test Results:
The competing products, which are mainly sold in Spain and the Czech Republic, actually provide some heat, but they produce much less air circulation and have a reduced output compared with the SolarVenti SV7 model.
Measured on the maximum air change the SPAH 3 only supplies 50% and the Sol Fresh 30 only 25% of the air volume which the SolarVenti is able to blow in.
Date of test report:
November 24, 2011
Tested models:
• SolarVenti SV7
• Dansolar DS1
• Scanheat: Scansun XL20/ Selsius SE07
Test Results:
The measurement showed that the SolarVenti SV7 model supplied an approx. 100% more effective airflow than the other two models, and a 41% and 24% higher efficiency, respectively, measured in watts per m² (coefficient of heat utilization relative to panel size).
DANETV
(Danish Centre for Verification of Climate and Environmental Technologies) has tested and approved a SolarVenti’s ability to dehumidify homes, vacation houses, clubhouses, etc.. and thereby create a better indoor climate.
Date of test report:
November 12, 2013
Tested models:
SolarVenti SV14
Test results:
The report shows that a SolarVenti actually keeps its promise: to get the moisture in the house down to a level so it doesn’t do any damage. Both the air flow and heat gain during the winter has been measured. The impact of the solar heater on a typical cottage of 70 m² without any other source of heat or ventilation than SV14 was calculated during a full year.
And it does the job!
Conversely, one must conclude that a solar air collector that provides significantly less than an SV14 is not able to do the job and you risk damage to the house. Therefore, ensure proper documentation like this DANETV report or similar when purchaseing an air collector. Many discount system do not live up to the advertising texts…

Fraunhofer-Institute: EN 12975 – Certification
“Fraunhofer-Institut für Solare Energisysteme ISE” has tested SolarVenti according to the European standard EN 12975-1, which includes quality and safety requirements for solar installations. SolarVenti is currently the only Scandinavian solar air collector that has been tested according to this EN standard.
Date of test report:
May 16, 2013
Test Results:
• SolarVenti complies with the EN requirements for solar installations.
• SolarVenti is thus EN 12975-1 certified.
Comment:
SolarVenti A/S participated in the development of the new EN standards * for solar collectors, so that solar air collectors were also included. The company conducts an ongoing dialogue with the institute to have the requirements for solar air collectors specified.
