— Solar potential
Morocco gets 3,000+ hours of sun per year.
One of the sunniest countries on Earth — and every region tells a different story. Here's the heat map we calibrate against.

— FAQ
Questions, answered.
Everything you need to know about solar sizing in Morocco.
The right size depends on your monthly kWh, your location's solar irradiation, roof area and orientation. Our sizing tool takes all these into account — enter your bills and location and we'll recommend the optimal system with full component specifications.
Costs vary by size and quality. A typical residential 3–5 kW installation runs 30,000–60,000 MAD. Commercial systems are proportionally larger. Our economic analysis tool returns a full breakdown — ROI, payback (typically 4–7 years), and lifetime savings.
Residential installs take 1–3 days once components arrive. Commercial installations take 1–2 weeks. End-to-end — from sizing to commissioning — usually 2–4 weeks, depending on supply and permits.
Yes — grid-tied, off-grid and hybrid. Off-grid sizing includes battery storage; hybrid combines grid connection with battery backup. The tool adapts and recommends the most cost-effective configuration.
High-resolution irradiation data from PVGIS, NASA POWER and SolarGIS, calibrated for Moroccan conditions — accurate, location-specific, accounting for seasonal variation.
