DuROCK Alfacing Ltd., SANYO Canada Inc., and AVACOS Solar Energy announced the first Canadian photovoltaic-system installation that combines SANYO’s double-bifacial solar PV modules and a DuROCK reflective roof membrane employing a white elastomeric roof coating.
The system has been installed at DuROCK Alfacing’s headquarters in Woodbridge, Ontario. DuRock’s TIOCOAT™ high-strength, white elastomeric urethane roof coating is reported to offer 89% solar reflectivity combined with a high degree of weathering resistance.

SANYO’s HIT® (Heterojuncotin with Intrinsic Thin-Layer) Double PV modules generate power from both sides, which are reported to result in up to 30% higher energy output than standard single-sided PV modules. The design makes the modules well suited for us on carports, canopies and porch coverings, the company says.
AVACOS Solar Energy is a Canada-based solar photovoltaic installation and project-integration company.
“DuROCK is proud to work with such industry leaders as SANYO and AVACOS on a project combining our technologies and expertise for the benefit of the environment,” said Gary Campacci, DuROCK president. “The installation of SANYO modules on our existing white reflective roof will ensure a maximum level of performance and cost effectiveness.”
In the 10-kilowatt grid-tied array, the bifacial PV modules will provide renewable energy revenue for DuROCK, while the TIOCOAT™ membrane will reduce the cooling costs of the building. The combination of the technologies results in increased PV module output from the cooling effect and increased exposure to solar radiation at the back of the modules due to the high reflectivity of the reflective roof membrane, DuROCK said.
“The merging of these two technologies is a great example of the potential that exists within this (solar) industry,” said Sandro Costa, AVACOS Solar president. “Maximizing the power generation possible from the sun is not only a win-win situation for the client, but for the environment and society as a whole.”
