A Canadian factory goes solar in a big way

All Weather at Home just flipped the switch on Canada’s biggest rooftop solar setup sitting on top of a busy window-and-door plant near Edmonton. The 1, 183-kW solar field stretches over 110, 000 square feet—about the size of two hockey rinks—and packs 2, 040 panels that each crank out 580 W. Together they make roughly 1. 3 gigawatt-hours every year, enough juice to keep the lights on in 1, 548 average Alberta homes and cut the factory’s power bill by 35 %. On weekends, any extra electricity slides straight into the provincial grid, saving about 632 tonnes of planet-warming CO₂ annually.What makes the project stand out isn’t just the size; it’s the company’s mindset. Instead of slapping panels up to look green for investors, All Weather has baked efficiency into its DNA for nearly fifty years. They already recycle more than 2, 000 pounds of uPVC daily, plus glass, cardboard, plastics and aluminum. Now they’ve turned their roof into a mini power station that should pay for itself in about seven and a half years. The real question is whether other manufacturers will copy the playbook or keep waiting for cheaper solar prices. Pulling it off took more than money—it took patience. The crew had to reinforce the roof, run permits through the city, and keep the factory humming while the solar gear went in. InfernoEnergy, the installer, said the client’s long-term vision made the hassle worthwhile.
