ClearVue tests different glazing options for solar-powered transparent glass

Australian smart building materials company ClearVue Technologies Limited has developed new product designs for its solar-integrated glass. ClearVue’s ability to now offer an energy-producing single-glazed and double-glazed low-emission insulating glass (IGU) laminated glass product in addition to its existing triple-glass design is significant, the company said.

New prototype IGU design with double glazing.

A test drive of the triple glazing solar glass from 2020 showed that the glass could produce 40 W of energy per square meter. The transparent product uses monocrystalline PV cell application methods. The power for the single glass design (30 W / m2) has been tested and determined under Standard Test Conditions (STC). The double-glazed panels are expected to generate slightly more power than the single-glazed design, but full testing is not yet complete.

“The ClearVue team in partnership with D2 Solar has worked hard for the past approximately 18 months to develop the new triple glazed design and expanded that work to produce these new single and double glazed designs,” said Victor Rosenberg, director of ClearVue. Chairman. “The addition of single and double glazed product designs to the ClearVue product suite is a quantum leap for the business with the single and double glazing that is perfectly suited for many retrofit applications, including in our main sales areas of the US and Europe, is well suited for automotive applications and can be used in countries where multiple glazing has no impact yet. “

According to a press release from the company:

The new single and double glazed designs are a major step forward for ClearVue and significantly increase the company’s sales opportunities in markets where triple glazing is currently not applicable or otherwise readily accepted. Equatorial regions, such as in Southeast Asia, where the sun is at a high angle, have traditionally been slow to adopt multi-glazed solutions. China has a wide range of temperatures, including much colder temperatures, where multi-glazed sizes, while logical, struggle with the added costs associated with the multiple layers of glass in multi-glass designs. The company expects that the single-glass and double-glass designs will make the road to the market in regions like this much smoother.

ClearVue also expects the single glass version of the product to be well suited to transportation applications, including the automotive sector, where many new electrical and other vehicle designs incorporate a dynamically tintable panaromic glass roof into their design. The company is convinced that the single-glass design integrates with these types of products, eliminating the need to consume power from an electric car’s batteries.

The double-glazed design is also perfect for the retrofit market, including the very large building upgrades market to meet new and revised building codes needed to meet net zero requirements in places like New York City and Chicago, and also in Europe, where the company has concentrated its marketing efforts over the past 12 months. Many older buildings in such places have heritage requirements and do not allow significant changes to the exterior. The ability to replace and upgrade existing glazing to energy-producing energy-efficient glazing without materially altering the appearance of the building represents a significant opportunity for ClearVue to meet all renovation projects where single, double or triple glazing can be specified.

The solar glass designs are still in the trial and testing phase, but ClearVue stated that a commercially ready-to-use product could be available in 2022. The development and testing of these products is in collaboration with the California solar engineering firm. D2 Solar.
