Clenergy’s PV-ezRack releases ascent ballast series for flat oofs
Clenergy has released two new low ballast solar mounting systems for flat roofs, dubbed the PV-ezRack Ascent and the PV-ezRack Ascent Wings.
The PV-ezRack Ascent is a low ballast, south/north facing solution without rails for PV installation on flat roofs while the PV-ezRack Ascent Wings is a low ballast, east/west facing rail-less system, which gives installers ideal surface utilisation and yield for structurally challenging roofs with limited ballast options.
With multiple angular options available, Ascent Wings allows maximised energy production.
Both Ascent and Ascent Wings are enhancements from the PV-ezRack ComT with ballast, a mounting solution exclusively designed for ballast systems last year. Compared with ComT with Ballast, the newly developed products boast an optimised structure and a more flexible tilt angle, with easier installation and a lower ballast.
“Clenergy has invested heavily in the R&D sector in recent years. Our in-house R&D team has developed seven innovative product lines for flat roofs thus far. It is exciting to have another two new additions,” Clenergy technical manager Lannes Cai says.
“And we will continue to invest more into product development in response to the worldwide diversified technical requirements for solar applications.”
The two have been put through stringent boundary layer wind tunnel tests, conducted by wind tunnel test agency Wacker Ingenieure. The test results are available upon request.
Additionally, the pair boast high efficiency in installation and warehouse management thanks to the click connection between the legs and bases. No additional tools are required for their assembly.
With a special design and a tilt angle of 10° and 15°, both Ascent and Ascent Wings are compatible with PV modules up to 2180mm by 1100mm. They are additionally flexible to PV module frames, with the height ranging from 30mm to 46mm.
They also comply with various internationally recognised standards, including Eurocode 0-9, AS NZS1170.2-2011, JISC8955 and ASCE 7-10.
