Certificates

As a leading manufacturer, Joule strives to constantly improve its manufacturing processes and finished production specification. The Joule product range is manufactured to the highest quality standards and is supplied to you the customer with full track and trace functionality. To further display our commitment to quality, Joule have tested there products higher standards than required and of those of our competitors.

Joule Acapella Evacuated Tube Collector

NSAI Certificate

A world leader in renewable technology, Joule, achieved the highly-sought after NSAI Agrément Certification. Awarded by the Irish Agrément Board (IAB), this certification is a true statement of quality and another feather in the cap for Joule.

Since the introduction of the Part L legislations in 2009, and the widened use of solar thermal technology in new build projects, it is now mandatory that solar thermal collectors are proven to comply with all aspects of the Irish Building Regulations. The Agrément certification is the only current method of proving this compliance.

Joule is the only solar company to be awarded this certificate on all three types of its collector range, including its in-roof and on-roof flat panel and it means that our products can be accepted by the Department of Environment on new build housing, plus all end users can be confident in Joule’s quality, reliability and durability. It also cements our reputation as the leaders in renewable technology in Ireland.

The NSAI Agrément certification is designed specifically for new building materials, products and processes that do not yet have a long history of use and for which published national standards do not yet exist. The Irish Agrément Board assesses, specifies testing, and where appropriate, issues Agrément certificates for such products.

Hail Test Certificate (Ice Ball Method)

TUV Rheinland is one of Europe’s most respected test facilities. Joule commissioned TUV to carry out “impact resistance tests” on the Joule Acapella Evacuated Tube. This test consists of an ice ball travelling at a given velocity perpendicular to the glass tubes. This test measures the force which the Acapella tube can withstand. The test was carried out in accordance with DIN EN 12975-2(2006). The collectors passed this test. The collectors passed this test as the glass used in the Acapella tube is made from borosilicate glass, also as our tubes do not rely on a seal of glass to metal the rigidity of the tube is enhanced.

Joule Navitas On-Roof Flat Panel Collector

Wind Loading Test Certificate

This test report describes mechanical load testing carried out to EN12975 to assess the wind loading and impact resistance of the Joule Navitas above roof solar thermal collector. Positive loading was applied to a single Navitas On-Roof thermal collector using pneumatic rams with suction cups. Unlike other collectors the test was carried out until failure of the collector occurred. Joule found that the maximum standard test settings did not cover all possible wind loads found and that additional testing should be carried out to find the collectors point of failure. An additional test was then carried out applying a negative load on the collector. Like the positive test this test was carried out to the point of failure. The results of this test show that the Joule Navitas collectors are able to withstand any recorded normal wind loading including a safety factor of two.

Impact Resistance

Impact resistance tests were carried out using method one of the details set out in EN12975, steel ball method. The steel balls weighing 150g were dropped from a height up to ma maximum of 2m above the collector. This ensures that the collector can withstand and normal expected impact during the collectors life span.

NSAI Certificate

Joule VisSolis In-Roof Flat Panel Collector

Fire Testing

This is an external fire exposure test for in-roof solar collectors which simulate the effect of burning material falling on to a roof from an adjacent building. The test specimens consist of a representative section of in-roof solar collector. Testers record the length of time which the sample continues to burn, the spread of flame and the degree of penetration. They then grade the materials for surface spread of flame (from A to D) and the roof system for resistance to penetration by fire (from A to D).

Under current requirements of the building regulations it is mandatory that all in-roof solar collectors must have a fire test completed and must achieve an A rating for fire penetration. Joule VisSolis in-roof solar collectors have achieved an A rating for both their tile and slate in-roof solar collectors.
