Solar System
High-Performance Energy for Large Businesses
A 66.5kW solar system is a large-scale commercial energy solution designed to power high-demand facilities such as manufacturing units, large warehouses, retail complexes, or multi-storey offices.
This powerful system dramatically reduces daytime electricity expenses, supports long-term sustainability targets, and provides an impressive return on investment through energy bill savings and feed-in tariff earnings.
Built with top-tier components and customised installation, the 66.5kW system is ideal for businesses that want to take full control of their energy future.
What’s Included in a 66.5kW Commercial Solar Package
- Tier-1 solar panels (typically 120 x 555W = 66.6kW nominal capacity)
- Commercial-grade inverter (string or hybrid configuration)
- CEC-approved isolators, cabling, switchgear & racking system
- Installation by accredited commercial solar professionals
- Up to 25-year performance and product warranties
- System monitoring app or web portal with live data access
With remote monitoring, you’ll track performance, generation, usage, and grid export — ensuring maximum transparency and control over your energy investment.
How Much Power Can It Generate?
A 66.5kW solar system typically generates around 250 to 290 kWh per day, depending on sun exposure, roof orientation, and local conditions — adding up to over 91,000 to 105,000 kWh annually.
This level of production can cut a significant portion of your business’s daytime grid consumption, with potential monthly savings of $2,000 to $3,500+, depending on load profile and tariff rates.
