Commercial Solar Panels for Performance-Driven Projects
Our commercial solar panels are engineered for businesses, developers, and installers who require reliable output, high efficiency, and long-term performance. Featuring premium 395W modules with 22.3% efficiency, these panels are suited to commercial solar installations across offices, warehouses, retail centres, industrial sites, and large-scale grid-connected systems.
When designing solar power for commercial buildings, efficiency per square metre directly impacts total system capacity. Higher-efficiency panels allow more kW to be installed on limited roof space, improving energy offset potential and return on investment.
SunPower Maxeon 3 395W – Designed for Commercial Solar
The SunPower Maxeon 3 395W Solar Panel (SPR-MAX3-395) is a premium monocrystalline module built around 104 Maxeon Gen3 cells. With a module efficiency of 22.3% and positive power tolerance (+5/0%), it delivers dependable commercial-grade performance.
Key Electrical Specifications (STC)
- Nominal Power (Pnom): 395W
- Efficiency: 22.3%
- Vmpp: 65.4V
- Impp: 6.04A
- Voc: 75.6V
- Isc: 6.57A
- Max System Voltage: 1000V (IEC)
- Maximum Series Fuse Rating: 20A
- Bypass Diodes: 3
These characteristics make it suitable for commercial string design across rooftop and ground-mounted systems. The 1000V rating supports common commercial inverter configurations, subject to Australian standards and system design requirements.
Thermal & Real-World Performance
Commercial rooftops in Australia can reach high operating temperatures, reducing panel output. The Maxeon 3 features a low temperature coefficient of -0.27%/°C, helping retain performance during hot summer conditions.
Lower annual degradation also supports long-term yield projections, with:
- Year 1 minimum warranted output: 98.0%
- Maximum annual degradation: 0.25%
Durability for Demanding Commercial Environments
Commercial solar panels must withstand environmental stress across decades of operation. This module includes:
- Wind load rating: 2400Pa (front & back)
- Snow load rating: 5400Pa (front)
- Hail impact tested: 25mm at 23m/s
- Operating temperature range: -40°C to +85°C
- IP-68 junction box
- Stäubli (MC4) connectors
It is certified to IEC 61215 and IEC 61730 standards, with additional testing for salt spray (IEC 61701), ammonia resistance (IEC 62716), PID resistance (IEC 62804), and desert exposure (MIL-STD-810G).
Applications for Commercial Solar
- Commercial building rooftops
- Warehouses & distribution centres
- Retail & office complexes
- Light industrial facilities
- Ground-mounted solar arrays
- Large-scale grid-connected projects
Bulk Commercial Solar Orders & Freight
We supply commercial solar panels in bulk for installers, developers, and large-scale projects. Trade pricing and palletised supply are available.
We can organise freight Australia-wide for pallet quantities. Alternatively, customers may arrange their own courier.
Please note: if freight is arranged independently, we cannot accept liability for damage in transit once goods leave our facility due to the fragile nature of solar modules.

Commercial Solar Panels FAQ
How much does a commercial solar system cost?
Costs vary depending on system size, roof configuration, electrical infrastructure, and installation complexity. Small commercial systems may start in the tens of thousands, while large-scale commercial solar projects can be significantly higher depending on capacity and site requirements.
What is the best solar system for commercial use?
The best commercial solar system combines high-efficiency panels, quality inverters, and correct system design. Panels with strong thermal performance and low degradation rates are typically preferred for commercial solar installations.
What is commercial solar?
Commercial solar refers to solar power systems installed on commercial buildings such as warehouses, factories, offices, and retail centres. These systems are larger than residential installations and are designed to offset business electricity consumption.
What is the solar 120% rule?
The 120% rule relates to electrical panel loading limits and determines allowable backfeed breaker sizing relative to the main breaker and busbar rating. Compliance must always be assessed by a licensed electrician in accordance with Australian standards.
Can I organise my own freight?
Yes, bulk commercial solar panel customers may arrange their own courier. However, we cannot accept responsibility for transit damage once goods leave our warehouse if freight is organised independently.
