For some early adopters of solar, the feel-good aspect may have unfortunately been dampened by the fact that most conventional photovoltaic (PV) and solar hot water systems have required penetrations in the roof.
These penetrations are best avoided; they can result in leaks in the short term and costly corrosion over time.
New accessory a penetration-free solar solution
Gerard now offers patented Solar Bracket accessories, allowing roof-mounted solar systems to be installed without creating entry points for moisture, meaning architects can specify a solar-ready roof without compromising performance and durability.
- 3mm thick aluminium-zinc magnesium (ZAM) coated steel.
- Secured directly into batten and rafter junctions where Gerard roof panels overlap.
- Suit any type of conventional PV or solar hot water system.
- Compatible with all Gerard pressed steel roof profiles, colours and textures available in the New Zealand market.
- Supplied with dense foam strips installed either side of the bracket for added weather security.
Installing on a new roof is ideal for ensuring the Solar Brackets are in the best possible location, however, they can be retrofitted to an existing Gerard roof, and a Gerard Certified Roofer can advise best practice for each scenario.
Gerard Product Innovation Manager Peter Richards explains it's a solution that architects and specifiers can be confident in: “Compatibility and weather security are paramount when installing any structure over a roof. Extensive weather security testing was carried out before the brackets were launched. We had the advantage of having the brackets used and exposed in our Japanese market for a couple of years before bringing them to New Zealand. There are a few differences in roofing structures between Japan and here, so a series of load testing was carried out to prove that the brackets exceeded the strength requirement of wind loads as we use them.”
Proven in Japan
Peter explains how Gerard Solar Brackets have come to feature on 4000 Japanese homes: “The Japanese government offered incentives to install solar over roofs, and one of our major customers indicated to us that they wanted a system which wouldn’t harm the roofing below. At this point, Japan and New Zealand worked together on the design and testing, with the final manufacture taking place in Japan. A second bracket was added to the original which allows installation under all of the profiles offered by Gerard Roofs.”
