COMMERCIAL SOLAR BY INDUSTRY
Helcro Solar designs commercial solar across eight Adelaide industry sectors. Every system starts from the specific energy profile and operating hours of that property - not a catalogue size.








COMMERCIAL SOLAR SYSTEM TYPES
Helcro Solar assesses every installation type as part of the commercial design process and recommends based on your property, tariff, and operating profile.



Standard for Adelaide commercial properties. Connected to SA Power Networks with surplus exported subject to your approved limit. Flexible export controls apply - sizing from your actual interval meter data and tariff profile is essential.

Cost-effective at commercial scale. Panels in series to a central inverter - suits roofs with consistent orientation and minimal shading. Our solar inverter installation in Adelaide team specifies the right configuration for complex roofs.
Commercial System Sizes
Sized from your actual interval meter data and operating hours. LGC eligibility begins at 100kW. Every system is designed to maximise self-consumption within SA Power Networks export limits.

Frequently Asked Questions
The best commercial solar provider in Adelaide designs your system from your actual interval meter data and SA commercial tariff structure, manages the full federal and SA incentive stack including STCs, LGCs, and Instant Asset Write-Off, and gives you a fixed price before any work begins. Ask any company you quote with how they sized the system and what incentives they've modelled. If they haven't looked at your tariff data or haven't mentioned LGC eligibility for systems over 100kW, you have your answer. Helcro Solar designs every Adelaide commercial system from your real usage data and backs every installation with a 10-year workmanship warranty.
A 30kW commercial solar system in Adelaide typically costs between $25,000 and $40,000 before incentives. After the federal STC rebate, a 30kW system can attract $8,000 to $15,000 off at point of sale. A 100kW commercial system typically costs $75,000 to $110,000 before incentives, with LGC eligibility reducing the effective cost further over time. System size, roof type, inverter specification, and metering complexity all affect the final price. Helcro Solar provides fixed-price quotes for every Adelaide commercial installation.
The number of panels depends on your building's energy consumption, operating hours, and available roof or ground space. A 30kW commercial system typically requires 60 to 75 panels at 400W per module. A 100kW system typically requires 200 to 250 panels. Adelaide's Zone 2 solar rating and SA Power Networks tariff structure both affect how your system should be sized. Helcro Solar sizes every Adelaide commercial system from your actual interval meter data and commercial tariff profile, not an industry average.
The 33% rule means a commercial solar system can have panel capacity up to 133% of the inverter's rated AC output. A 30kW inverter can legally support up to approximately 40kW of panels. This deliberate DC oversizing compensates for reduced output during early morning, late afternoon, and overcast periods, maximising generation across the full operating day. For Adelaide commercial properties, SA Power Networks flexible export controls can curtail midday grid export, making the extra shoulder-hour generation from 133% DC oversizing especially valuable for businesses operating outside peak solar hours. Helcro Solar applies DC oversizing to every Adelaide commercial system design as part of the CEC standards we follow.
The 20% rule refers to SA Power Networks flexible export controls, which limit how much solar energy a commercial property can export back to the grid at any given time. Export limits are set based on network capacity in your area and can be as low as 20% of your inverter's rated output. This does not limit how much your system generates or self-consumes. For Adelaide commercial operators, this makes self-consumption the primary ROI driver. Helcro Solar designs every Adelaide commercial system to maximise self-consumption within the SA Power Networks export framework, so your system performs against your actual tariff rather than an optimistic export scenario.
For most Adelaide commercial properties, additional panels deliver stronger returns up to the point where daytime self-consumption is maximised. Beyond that, solar battery installation in Adelaide becomes more valuable - shifting surplus generation to evening demand, avoiding peak tariff periods, and managing demand charges. Commercial systems over 100kW also earn Large-scale Generation Certificates for every MWh produced. For Adelaide commercial operators subject to SA Power Networks export curtailment, battery storage converts otherwise wasted midday generation into usable evening load at your commercial electricity rate.
Adelaide commercial feed-in tariffs average around 2 to 5 cents per kWh, while commercial electricity costs 18 to 28 cents per kWh depending on your tariff structure. Every kilowatt-hour self-consumed is worth up to fourteen times more than one exported to the grid. Commercial systems over 100kW earn Large-scale Generation Certificates in addition to the feed-in tariff. Helcro Solar models your self-consumption profile and commercial tariff as part of every Adelaide commercial solar design, so the projected return reflects your actual operating hours and consumption pattern rather than a generic export-heavy model.
