Replace your roof shingles with our system and start saving on electricity bills today!
Founded in 2016, CHE is the exclusive Canadian partner of IRFTS, now part of Edilians Group, and Europe’s leading building integrated solar-PV (BIPV) provider.
Simple Solar is an experienced solar solutions company with an impressive portfolio of successfully completed projects.
Your CHE Solar Roof will generate ~1,200k kilowatts-hour (kWh) of clean electricity per year for every kW of installed capacity (South-facing orientation – Calgary, AB).
Adjustable frames that can accommodate different PV-panel sizes.
In Canada, the CHE BIPV system must be mechanically attached to the roofing deck by six (6) brackets per frame/solar-PV module and must use locking bars parallel to the slope of the roof and snow deflectors installed perpendicular to the slope of the roof.
When fully locked in place with solar-PV modules, the IRFTS Easy Roof Evolution system can withstand a snow load of between 3.0 and 7.5kPa (from most unfavourable to most favourable bracket location).
Example based on NBC 2015 for Vancouver, BC:
For the ultimate snow load of 2.7kPa and using the average system capacity of 5.25kPa yields 5.25kPa>2.7kPa and a resulting in an average safety factor of 1.94.
When fully locked in place with solar-PV modules, the IRFTS Roof Evolution system can withstand a wind load [downward (+) / uplift (-)] of between 3.8 and 9.75kPa (from most unfavourable to most favourable bracket location).
Example based on NBC 2015 for Vancouver, BC:
For the ultimate wind load of 1.0kPa and using the average system capacity of 6.8kPa yields 6.78Pa>1.0kPa and the resulting in an average safety factor of 6.8.
Extensive testing has been undertaken by IRFTS to confirm the strength of the support bracket connection to the underlying roof deck. The table below shows the ultimate downward (snow/wind) and upward (wind) resistance of individual bracket connections to the roof deck.
Roof Deck | Ultimate Downward Force on the Most Susceptible Bracket Before Failure (kPa) | Ultimate Upward Force on the Most Susceptible Bracket Before Failure (kPa) | |
OSB | 9mm | 3.00 | 3.86 |
12mm | 3.17 | 6.29 | |
15mm | 3.32 | 6.80 | |
Plywood | 9mm | 3.74 | 5.89 |
12mm | 5.80 | 7.63 | |
15mm | 7.57 | 9.75 | |
Modern PV modules are made with strong anodized aluminum alloys and impact-resistant 3mm clear glass and are designed for 5.0kPa snow loads and a 2.5kPa wind loads.
PV modules sold in North America are tested against hail in accordance with UL 1703 and UL 61703 standards. Lab technicians drop a two-inch (50mm) solid steel sphere from a height of 51 inches (1295mm) onto the surface of the PV module, the energy equivalent of a hail stone measured at one inch and three-eighths in diameter (35mm) falling at terminal velocity through the sky.
