It was big news at last year's Intersolar 2021 when Meyer Burger unveiled its new solar tiles designed by paXos. At Intersolar 2022, paXos will present a range of new innovative applications, including the "Solar Solar Beaver Tail Tiles, which come in black and, most importantly, terracotta.
Building-integrated PV (BIPV) is showing strong performance at Intersolar 2022, a good sign that the still niche application is finally on the cusp of wider adoption. As the long battle between PV engineers and architects confirms, the main opposition to widespread adoption is aesthetic in nature. However, innovations such as the terracotta Beaver Tail from paXos hold great promise, as many European buildings are historic, monumental structures that require a degree of aesthetic appeal.
In many European countries, such as Poland, the use of plain tiles is widespread, and the demand for BIPV appears to be indelibly linked to the technology's ability to remain unobtrusive. Marius Nennewitz, a paXos project manager, told pv magazine that the Beaver Tail tiles were designed in collaboration with Fraunhofer ISE, to reduce their reflectivity, in accordance with local requirements. The result is a duller, rust-colored tile.
Like the Solar Roof Tile Mild-Hybrid product that paXos sold to Meyer Burger, the individual tiles can be removed and replaced as needed. PaXos has ensured that the tiles have a high hail and storm suction resistance, while the roofs can be walked on. However, the heat consumption is lower than with mild hybrid systems, in favor of aesthetic improvements.
