Woodbridge, Ontario -- Environmental equipment suppliers Sanyo Canada Inc. and Avacos Solar Energy say they have unveiled the first Canadian photovoltaic system combining two-sided solar PV modules with a reflective polyurethane roof membrane.
The set-up was installed at Durock Alfacing International Ltd's headquarters in Woodbridge, said a 15 Dec statement from the companies.
Project manager Avacos, a Canadian solar photovoltaic installation company, matched these complementary technologies, and said this gave additional cost-savings and environmental benefits.
According to Avacos, Sanyo's new HIT (hetero-junction with intrinsic thin-layer) PV modules are double sided, and so can generate power from both sides, resulting in up to 30 percent higher energy output than with single-sided PV modules. This makes them ideal for carports, canopies and porch coverings.
Meanwhile the Durock Tio-Coat, a high-strength white urethane elastomer roof coating, provides 89 percent solar radiation reflectivity and weather resistance, reducing the energy usage required for the building compared to traditional roof coverings.
"The installation of Sanyo modules on our existing white reflective roof will ensure a maximum level of performance and cost effectiveness,"commented Gary Campacci, president of Durock, in the statement.
In the 10kW grid-tied array, Sanyo's PV modules will provide renewable energy revenue for Durock, while the Tio-Coat membrane will also reduce the cooling costs of the building, said Avacos. Combining these technologies results in increased PV module output from the cooling effect. It also increases exposure to solar radiation at the back of the modules, due to the high reflectivity of Tio-Coat roof membrane.
Merging these technologies "is a great example of the potential that exists within this (solar) industry," said Sandro Costa, president of Avacos Solar, in the announcement, adding that maximising power generation from the sun is "a win-win situation" for the client and the environment.
