Our Story

Most homeowners and businesses are stuck overpaying for energy because they receive cookie-cutter quotes — generic numbers that ignore their real consumption, roof, or seasonal patterns.

Hajar Affane is a renewable energy engineer, not a salesperson. Trained at the International University of Rabat (UIR), she serves families and businesses across Morocco, Canada and the United States. She doesn't recommend what's in stock — she analyzes your actual consumption and designs exactly what you need to cut your bill as fast as possible.

Every roadmap is built from first principles: real consumption data, shading analysis, structural pre-check, ROI modeling, and 90 days of support that lasts long after installation day.

What guides every project

Certified Engineering

Every roadmap is signed by a UIR-certified renewable energy engineer — not a sales rep.

Real numbers, not estimates

Real consumption data, real shading analysis, real ROI numbers — no marketing fluff.

Three countries, one expert

Local code knowledge in Morocco, Canada and the USA — global engineering standards.

Transparent pricing

One-time fee, all-inclusive. No hidden commissions, no vendor kickbacks.

The team behind the engineer

An engineer who designs it. A certified crew who installs it. One team accountable to you.

Hajar's roadmap is only as good as the hands that execute it. That's why SOLAR BY JO runs its own in-house installation crew — same uniform, same standards, same phone number on day 1 and day 1,000. No subcontractor roulette, no finger-pointing if something goes wrong.
