BC Housing Complex Upgrades with Solar Power: Solar Grid Tie Project to be Western Canada's Largest

A social housing development in Surrey, British Columbia is getting a green energy upgrade with the addition of a grid-tie solar power system from Carmanah Technologies Corporation (CMH:TSX).

As part of BC Housing's commitment to developing sustainable social housing, Greenbrook will be equipped with a grid-tie solar power system designed to provide 10 percent of the development's annual electricity requirements to assist with common area loads such as area lighting and air source heat pumps.


Valued at approximately $1.34 million in total, the photovoltaic system will be installed in stages by Carmanah Technologies under contract with Yellowridge Construction Ltd., with completion scheduled for mid 2010. With a combined capacity of approximately 139 kW, the site-wide renovation project represents Carmanah's largest grid-tie project to date, and Western Canada's largest solar grid-tie project.

Located in Surrey's Newton Town Centre, the Greenbrook complex includes 29 buildings with 127 town houses. The grid-tie system will connect to the electric utility through multiple net metering connection points within Greenbrook's common distribution electrical system.

In designing the photovoltaic system, Carmanah representatives combined a comprehensive site evaluation with best industry practices and practical implementation strategies to design a system that would meet the challenges of local shading issues, fixed orientation of structures and an annual energy target of 130 MWh. This solar power upgrade is one aspect of a site-wide building envelope replacement that addresses a range of other improvements such as drainage, electrical, landscaping and mechanical upgrades.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
