Systems greater than 100kW of Solar Panel capacity are not eligible for the Small-Scale Renewable Energy Scheme, meaning they typically have a larger upfront cost. These systems create large-scale generation certificates which can be sold at the end of each year of production.
Pricing for 200kW solar systems
The cost of installing a solar system has fallen significantly in recent years thanks to a number of factors, including Australian government incentives for renewable energy, growing competition between solar panel installers and component manufacturers, and global manufacturing trends.
Solar Choice holds live pricing on Solar PV system sizes from 1kW to 10MW, however LGC system sizes average prices are not published. To see average system prices for commercial system sizes up to 100kW see the Solar Choice Commercial Solar PV Price Index.
To give you an idea, the indicative cost of a 200kW roof-mounted solar power system would range from $340,000 to $380,000 excluding GST.
There are some common factors that can influence the price of an installation:
- Generally groundmounted arrays cost more than rooftop installations
- Long AC or DC cabling distances (>50m)
- Requirements to trench and backfill
- Concrete, tiled or partly shaded roofs

Energy yields for 200kW solar systems
There are many factors that influence the output of solar PV systems. These include the orientation and tilt angle of the solar panels, the presence or absence of shading, average system operating temperature, and the quality of the system’s components. All of these factors are taken into consideration when a system is designed in order to arrive at a reasonable estimate as to what that system’s power output will be once it is operational.
Using some typical conditions for a commercial roof space we have generated the below indicative figures to give you a guide.
|200kW Solar Power System Output Estimates by Capital City|
|Adelaide||770 kWh per day|
|Brisbane||800 kWh per day|
|Canberra||770 kWh per day|
|Darwin||880 kWh per day|
|Hobart||620 kWh per day|
|Melbourne||670 kWh per day|
|Perth||840 kWh per day|
|Sydney||720 kWh per day|
A solar system produces more energy in summer than in winter:
For example, a standard 200kw solar system in Sydney, NSW would produce about (3kWh x 200kW =) 600kwh on a winter’s day, while in the peak of summer the same 200kw solar PV system would produce around (5kWh x 200kw =) 1,000kwh.

Financial returns for 200kW solar systems
According to Solar Choice data – payback periods for small LGC commercial-scale solar systems in Australia are around 5 years on average, with internal rates of return (IRR) easily hitting 20% in every state & territory in the country.
That being said, the investment case for installing a 200kW solar system depends on the circumstances. The 5 biggest factors that influence Commercial Solar ROI are:
- Energy consumption matching daylight hours
- Roof structure and material
- Getting a competitive price via a solar tender
- Roof Slope and Azimuth
- Existing rates negotiated with the electricity retailer
Commercial Solar System Finance Options
There are a number of different solar financing options available to businesses that can create a cash flow positive solution from the commencement of the project with zero upfront costs required. Different terms, fixed/variable repayments and ownership models exist and it is recommended to consider all options prior to making a decision.
Solar Choice have independently assessed the pros and cons of the different options available in our Commercial Finance Guide.
Run a Solar Tender for your large-scale Commercial Solar Project
The best way to get a high quality solution and attract innovation from Australia’s leading commercial installers is by running a Solar Tender. Solar Choice has managed tenders across many of Australia’s largest Solar PV installations enabling clients to attract ALL major commercial installers in Australia to put together their best proposal.
Solar Choice via their free tender management platform helps design the optimal solar solution, invites the best-fit accredited installers to participate, prepares an apples-for-apples
comparison across multiple proposals and provides independent expert advice on products, system design, warranties and financing options.
