Commercial solar power system cost guide for businesses in Sydney

KUGA has provided examples of basic commercial solar installation and cost in Sydney. Note that the table below provides typical price ranges and does not cover all examples. The commercial solar power system cost also does not include solar battery storage.

Additional costs to be aware of for your commercial solar power system

Solar Network Protection

All commercial inverters are designed to shut down in the event of a power cut. Any commercial solar inverter which is above 30kW in capacity needs a separate network protection unit. This is a legal requirement in Sydney and is included in any KUGA commercial solar install. Adding this equipment can increase the price of your solar install by $6,000 – $7,000.

Extra cost associated with adding tilt to commercial solar panels and power systems

Looking at commercial solar power systems around Sydney, you may note that some are laid flat on a roof. Other solar panels are tilted to face the sun more directly.

Whether or not your Sydney business needs to tilt its solar panels depends on two factors:

  • Building orientation
  • The times of day the business consumes energy

For a detailed explanation as to how KUGA designs commercial solar panels in Sydney, refer to our panel tilt guide.

The table below shows the cost of adding tilt onto your commercial solar systems.

Length of the cable run from solar inverter to switchboard

Switch board connections

In an ideal world, a commercial solar installation would have inverters located as close as possible to the switchboard. The length of solar cabling ought to be minimized for both cost and voltage drop reasons. Unfortunately, the design of a building or internal equipment may necessitate extra cabling.

Using the same commercial solar size examples as above, note the cost of adding extra cable run to your commercial install.

TIP: Ensure you always ask your Sydney solar installer where the inverters are going to be located. Ensure extra cable run has been allowed for if it cannot be avoided.

How much solar will your commercial panels produce in Sydney

There is a difference in sunshine, therefore, solar production is different in each state. For Sydney, the average daily energy production per kW of solar is 3.9kWh. This means a 100kW system should produce 390kWh of electricity.

For Sydney, see the below examples of solar production and output from Kuga’s installations.

99.9KW Sydney Commercial Solar Production Data

KUGA Electrical actively monitors the performance of all their commercial solar installations for their Sydney clients. In this example, the client’s actual solar production is compared with the business case. The real dollar savings are also calculated, based on their electricity rates.

You will note that KUGAs estimates to the Sydney factory were understated by 5.4%. The conservatives estimates ensure your Sydney business will achieve the electricity savings promised by a commercial solar installation.

200KW Sydney Commercial Solar Production Data

In a similar example, one of KUGAs actual 200kW solar installations was compared to the business case. The savings generated for this large Sydney business were 7.4% higher than estimated.

How many rebates can you get with your commercial solar installation in Sydney?

Any commercial solar power system in Sydney is subsidised. This is done under the STC, or Small-Scale Technology Certificate (STC) programme. In Sydney, a solar installation will attract 14 STCs for every kW of solar energy installed.

A Sydney commercial solar system over 100kW in size is also eligible for the rebate. In this case, the rebate is provided by way of LGCs, or Large-Scale Certificates.

The difference between the two types of rebates is: STC solar rebates are claimed upfront before you pay for your system. In contrast, LGC solar rebates are paid pack to you over a period of 10 years.

Both STC and LGC rebates are traded differently and will have different market values at any point in time.

If your Sydney business is on the cusp of needing 100kW of commercial solar, it is worth considering the value of each rebate option.

The table below shows the difference in solar rebate for a 99.9kW (STC) and a 100 kW (LGC) installation.

[table id=10 /]

Note: the STC rebate figures are actual values based on installing a 99.9kW commercial solar system on a Sydney business. The LGC values are approximate for a Sydney commercial solar installation, because since they are claimed over a period of 10 years, there may be significant fluctuations in the market value.

Finance for Commercial Solar Panels in Sydney

There are a variety of ways to pay for your commercial solar installation on your Sydney business. In almost all cases, the business can finance the solar panels’ repayments to ensure $0 upfront. The solar will also generally remain cashflow positive over a 4-5 year term or beyond.

Below are some scenarios showing the funding options and when a Sydney business would select each.

It may make sense for your Sydney business to purchase commercial solar panels outright if:

  • The business has sufficient cash reserves
  • Is looking to write off a significant amount of tax. If the commercial solar power system cost is under $30,000 the asset can be fully depreciated over a 12-month period.
  • The business wishes to avoid interest charges
  • The owner doesn’t want to spend time on excess paperwork and approvals

Rent to own example in Silverwater, Sydney

Another popular solar funding option in Sydney is a “rent to own.” One of KUGAs installs in Silverwater has a 37kW commercial solar system. The funding benefits include:

  • Cashflow positive of $5,776 each year, on a 7-year rental term.
  • All repayments are 100% tax-deductible since they are expenses.
  • There was an option to delay the first payment for 90 days, increasing the cash flow positive aspect. In summer periods, this Sydney business would have 90 days of savings before the first rental installment.

The risk-free way to get solar on your Sydney business

Many Sydney business owners are sceptical of the recent “boom” in solar installers. For them, they wish to reduce their electricity overheads without running the risk of their installer going belly-up. In this case a Power Purchase Agreement (PPA) is an attractive option.

Benefits of a commercial solar PPA include;

  • No solar ownership. A third party borrows your roof to install solar
  • Long terms are available (up to 20 years).
  • Cheaper electricity rates than any conventional retailer are able to offer with guaranteed ZERO price increases over the duration of the contract.

Sydney’s newest and most creative solar financing option has just launched

Sustainable Australia Fund (SAF) has existed since 2002. However, it was not until 2019 that it opened its solar financing services to the Sydney market.

SAF offers a unique type of finance known as an Environmental Upgrade Agreement (EUA). The loan is attached to the title of a commercial property. Any building upgrade including commercial solar power systems can be funded, provided there is an environmental benefit.

Repayments are collected via participating Sydney Councils, in the regular rates notices.

This is a great option for Sydney commercial property investors, as the solar power system cost can be passed directly on to the tenant.

Currently, the participating Councils in NSW are:

  • Blacktown City Council
  • Parramatta City Council
  • City of North Sydney
  • City of Sydney
  • Lake Macquarie City Council
  • Newcastle City Council

KUGA Electrical is one of the very few installers approved by ASF to complete their commercial solar installations.
