Commercial solar panels in Sydney NSW

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 are the benefits of commercial solar power in NSW?

Solar power is one of the best ways for NSW businesses to save money on their energy bills. Commercial solar power systems are more affordable than ever in Australia, which is why a large (and growing) number of businesses with unshaded roof space and ample daytime electricity loads have gone or are going solar. The main benefits are listed below.

Low solar prices

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).

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.

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 12 years.

How much energy will a solar system produce?

As a rule of thumb, a solar PV system in Sydney will generate roughly 4 kilowatt-hours (kWh) of energy per kilowatt of capacity per day on average throughout the year (with more int he summer months and less in the winter). This means that a 10kW solar system will generate about 40kWh of energy per day, while a 100kW solar system will generate about 400kWh per day. Actual energy yields will vary depending on location, orientation & tilt angle and components used.
