Solar Choice’s head office is based in Sydney and we have proven track record in commercial solar projects all across Australia over the last 16 years. This article provides an overview of the important considerations for businesses considering solar in Sydney and surrounding NSW regions.
Is Commercial Solar Power Worth It In Sydney?
Based on historical sunlight data from the Australian Bureau of Meteorology, you will receive 3.87 kilowatt hours (kWhs) on average per day for each kW of solar installed on your roof in Sydney. This figure is higher in summer and lower in winter, and depends on the tilt and orientation that the solar panels are installed. Using these averages see the below table which shows how a typical commercial solar panel system will perform.
| Solar System Size | Average Daily Generation (kWh) | Annual Solar Generation (kWh) | Assumed Rate Paid by Business | Annual Savings (assumes 70% self-consumption) |
| 10kW | 39 | 14,126 | $0.35 per kWh | $3,673 |
| 39kW | 151 | 55,089 | $0.25 per kWh | $10,467 |
| 70kW | 271 | 98,879 | $0.21 per kWh | $16,018 |
| 100kW | 387 | 141,255 | $0.18 per kWh | $19,917 |
| 500kW | 1,935 | 706,275 | $0.15 per kWh | $84,753 |

Prices for Commercial Solar Panels in Sydney
Solar power has never been more affordable in Australia, thanks in part to federal government subsidies available through Australia’s Renewable Energy Target (RET). For solar systems up to 100kW in capacity, the RET provides an up-front incentive in the form of Small-scale Technology Certificates (STCs). For systems larger than 100kW, the RET provides an ongoing incentive (until 2030) in the form of Large-scale Technology Certificates (LGCs).
The below table shows average pricing for commercial solar installations across each capital city. This is published and updated monthly in Solar Choice’s commercial price index
Average Commercial Solar Sydney Costs
| 10kW | 30kW | 50kW | 70kW | 100kW | |
|---|---|---|---|---|---|
| Sydney, NSW | $10,520 | $26,840 | $48,390 | $63,480 | $83,370 |
Solar Choice keeps track of commercial solar system prices for capital cities around Australia noting a ~40% decline in the cost of a fully installed commercial solar PV system in the last 5 years. For a full breakdown of cost trends by city and system size – visit our Commercial PV Price Index articles. The data used to create the table is sourced from our installer network database, which includes about 100 installers from across Australia.
Low Maintenance Requirements
Solar systems – unless they are perched on solar trackers – generally have no moving parts and require very little in the way of maintenance or inputs once they are installed and functioning. In most cases the natural tilt of the panels will enable them to be cleaned in heavy rainfall, so it is not worth the cost of getting solar panels cleaned. Generally speaking it is worth getting an electrical inspection every 3-5 years to ensure all components are performing well.
Tax benefits for businesses with solar
ABN holders may be able to claim depreciation and GST credit on solar system energy yields. There are also tax benefits through lease agreements and Solar Power Purchase Agreements which enable the asset to be off balance sheet.
Financing for Commercial Solar Systems in Sydney
There are a number of different ways to finance a solar system in Australia which can provide a cash flow positive solution from day one with no upfront costs. The 3 most common options are detailed in the below table.
| Type | Description | Typical Terms |
| Chattel Mortgage |
|
5% to 8%
2 to 10 years |
| Rent to Own (operating lease) |
|
5% to 8%
2 to 10 years |
| Power Purchase Agreement |
|
8c per kWh to 15c per kWh
7 to 30 years |

Popular commercial solar system sizes
The most common sizes used in commercial solar installations are 10kW, 30kW, 50kW and 100kW. Solar systems can of course also be any size in between, and may also be much larger. See some examples of below of the hundreds of Commercial Solar project Solar Choice has assisted with over the last 16 years.
