TEST documentation

Delta Centre of Test Excellence 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. And the results also show that SolarVenti deliver what they promise!

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:
November 12, 2013

Tested models:
• SolarVenti SV14

Test Results:
The report shows that the SolarVenti models reduce the water content of the indoor air and the building construction by a combination of ventilation and heating.

The result is a reduction of the relative (% RH) and absolute humidity. The SolarVenti thus improves the indoor climate and helps to maintain the building and the inventory. A SolarVenti will have the biggest impact from October to June.

DanETV (The Danish Centre for Verification of Climate and Environmental Technologies) has tested and verified the ability of a SolarVenti to dehumidify a summer house, clubhouse etc.

Date of test report:
August 21, 2013

Tested models:
• SolarVenti SV7
• Sol Fresh 30    (= GS20 og Air Max 50)
• SPAH 3            (= GS30 og Air Max 75)

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:
August 31, 2012

Tested models:
• Scanheat Model 400
• SolarVenti SV3

Test Results:

The small SolarVenti® SV3 surprises in the test. The solar warm air collector SV3 uses solar radiation very effectively despite its small format.
Compared SV3 provides twice the air than the larger model Scanheat 400.

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 the ability of a SolarVenti to dehumidify homes, clubhouses, etc. and thereby create a better indoor climate.

Testbed for air collector.

In the period 2010-2011 the research project "Thermal solar" at DTU Byg. The project aims to set up a test stand for testing the air collectors as well as test solar air collectors.

Solar Heating Products are tested according to the standard of the product. Solar air collectors are tested in accordance with the European solar standard EN 12975 Parts 1 and 2 from 2006 and the draft standard for air solar collectors which rely on solar norm [1,2].

DTU Byg are also involved in the preparation of standards for the testing of air collectors as part of the project.


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.
