Commercial Solar Power in Sydney NSW – Prices, Output and Returns

Sydney Maritime Musuem commercial solar panel install eArche 235kW

Solar power is an attractive investment option and great way to save money for businesses in Sydney and across the rest of New South Wales. This article provides an overview of commercial solar power in Sydney, as well as the rest of NSW.

What is the typical return on investment for Commercial Solar Projects?

Based on historical sunlight data from BoM, you will receive 3.87 kilowatt hours (kWhs) on average per day for each kW of solar installed on your roof. 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.

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

Commerical Solar Prices

Low maintenance investment

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.

  • Responsibility to maintain the asset remains with ppa provider through term of agreement
  • Only financing method where asset is off balance sheet
  • Learn more about PPAs and see an example
8c per kWh to 15c per kWh

  1. I am the chair of a body corporate which has some electrical issues within the building. We are currently engaged with an electrical consultant to discuss the issues within the building and are looking at using solar as a solution to provide adequate power to the units. There are 15 apartments in total.
