Is solar right for my business?

This is a question many WA business decision-makers ask when they’re considering solar.
You want to enjoy the benefits of sourcing energy from the sun – but it also needs to be a viable business decision. 

Use your usage history to help you figure out the ideal system size

Your minimum daily load (generally between 12pm and 1pm) averaged out over 7 days, is a useful way to help identify the optimal system size. Easily get access to this data via My Account.

How much could my business save with solar?

With solar, your business could save on its electricity costs. How much you could save will depend on a number of factors including the size of your business, the way your business uses electricity and size of the solar PV system. 

When we recommend a solar solution for your business, we’ll be able to estimate your potential savings based on your unique electricity consumption profile and the recommended system size. 

Once your system is installed, we’ll show you how to calculate the savings you are making on your electricity costs –quickly and easily. It’s important to remember that network charges and supply charges (for the amount of electricity that you draw from the grid) will continue to form part of your bill.

How big does my solar system need to be?

Choosing the right system size should be based on how much electricity your business uses during daylight hours.

For maximum efficiency, your business should use all of the electricity the system generates, as this is generally more beneficial for your business than exporting excess electricity to the grid. 

When will my solar system pay for itself?

The time it takes for any savings on your electricity cost from installing solar to equal the cost of the investment in the system is known as the payback period.

In some of our previous projects, the payback period for some WA businesses has been within two or three years – but it’s important to understand that not all businesses will benefit financially from investing in solar. 

The way your business uses electricity depends on a range of factors, including your industry, location and operations. Electricity consumption alone may not be a good indicator of whether you might receive a positive return on your investment.

Financial factors affecting your payback period

Peak vs off peak rates If your business pays a higher rate for using electricity during peak times and a lower rate during off peak times, this could increase your payback period.
Fixed vs variable prices If your electricity costs include a high proportion of charges that don’t change based on the amount you consume (such as fixed charges), your electricity costs might not be reduced by installing a solar system.
Minimum usage plans If your electricity plan requires that you pay for a minimum amount of electricity regardless of whether you consume that amount, installing a solar system may not reduce your electricity costs.
Network charges Network charges cover the costs associated with transporting electricity to your premises. These charges may or may not change after installing a solar system.
