Silicon Solar designs and installs commercial solar systems from 25kW to 100kW for businesses across Melbourne and Victoria, helping offices, warehouses, factories, retailers and community facilities cut daytime energy costs.
Because businesses use most of their electricity during daylight hours, commercial solar often pays for itself faster than residential systems. We model your load profile, design the system, manage network approval and install around your operations.
Commercial Solar System Sizes
| System | Average daily output | Estimated yearly output | Typical sites |
|---|---|---|---|
| 25kW | About 90 kWh | About 33,000 kWh | Offices, retail, hospitality, clinics, workshops |
| 50kW | About 180 kWh | About 66,000 kWh | Warehouses, factories, schools, supermarkets |
| 100kW | About 360 kWh | About 130,000 kWh | Large warehouses, manufacturing, cold storage |
Estimates use Melbourne’s average of roughly 3.6 kWh per kW of panels per day. We model your actual roof and usage in your proposal.
Need something in between, or a 10kW system for a small shop or home business? We design to your site, not to a fixed package. See our 10kW solar system for smaller premises.
