39.9kW Commercial Solar System
Smart Power for Expanding Enterprises

A 39.9kW solar system is a robust and efficient energy solution built for larger mid-sized commercial operations. Whether you operate a multi-tenant retail centre, large office, warehouse, or light industrial facility, this system helps significantly reduce electricity costs, boost sustainability, and future-proof your energy infrastructure.

Engineered with premium components, the 39.9kW system delivers high daily energy output, with the added benefit of exporting excess electricity to the grid — earning feed-in tariff credits and enhancing ROI.

What’s Included in a 39.9kW Commercial Solar Package

  • Tier-1 solar panels (typically 90 x 445W = 40.05kW nominal capacity)
  • Commercial-grade inverter (string or hybrid options available)
  • CEC-approved switchgear, isolators & mounting equipment
  • Professional installation by accredited electricians
  • Clean Energy Council (CEC) certified components
  • 25-year panel performance warranty, 10-25 years product warranty
  • Remote monitoring via mobile app or web portal

With an active internet connection, you’ll gain full visibility of your energy generation, consumption, and export — accessible anytime, anywhere.

How Much Power Can It Generate?

On average, a 39.9kW solar system generates approximately 150 to 175 kWh per day, depending on panel orientation, weather, roof tilt, and geographic location. That’s 54,000 to 64,000+ kWh annually.

This generation level can offset a significant portion of your business’s electricity consumption, leading to estimated savings of $1,200 to $2,000+ per month, depending on energy usage and feed-in tariff rates.
