Project at a Glance

A Growing Tech Company With Predictable Daytime Load

Atlantic Tech operates out of a two-story office building on the edge of downtown Halifax, with a flat commercial roof and a workforce that runs standard business hours. That combination made the building a strong candidate for solar: nearly all of the company's electricity use happens during daylight hours, which is exactly when a rooftop array produces the most.

The company's leadership had made public sustainability commitments to clients and investors, and wanted a measurable way to back those commitments up. Their annual electricity usage ran 58,000 kWh, with a monthly NS Power commercial bill averaging $1,240. Beyond the environmental angle, the finance team wanted a project that also made sense on a straightforward payback basis.

Footnotes: Commercial rate model uses current NS Power commercial pricing with projected annual escalation consistent with approved residential increases. ITC eligibility and rate depend on business structure and should be confirmed with a tax professional. These are non-binding estimates. Actual results depend on weather, equipment performance, and program continuity.

Key Takeaways

What This Project Teaches

  1. Daytime-heavy loads make the strongest commercial case. A standard office schedule lines up almost perfectly with solar production hours, which is why this project's offset percentage ran higher than most residential installs.
  2. The federal ITC changes the payback math substantially. Without the Clean Technology Investment Tax Credit, this project's simple payback would run closer to eleven years instead of under eight.
  3. Flat commercial roofs need engineered ballasted racking. No penetrations were made into the roof membrane, which matters for a building still under its original roof warranty.
  4. Sustainability reporting was a real business driver, not an afterthought. The monitoring dashboard now feeds directly into the company's investor and client sustainability reporting.
