What size solar energy system does your business need?

Adding solar, or thinking about adding solar to your business? Here's some guidance on what size solar energy system your business will need.

Solar power is still on its upward trajectory with businesses and homes across Australia taking advantage of this abundance of glorious sunshine. And the fastest growing solar market is commercial energy systems between 75-100 KW. And thanks to solar panels on the rooftops of homes and businesses across the country, Australia now receives 3% of its energy supply from ‘small-scale solar’.

If you have been considering a solar energy system for your business, you might be wondering what size system your business would need. A great way to check what size system your business will need is by collecting your interval bill from your energy provider and analysing the numbers. We’ve written a post on this here and it’s something we can help you analyse if you have the information available. Our post also includes links to collect the information from your energy retailer if you don’t already have access.

You can always get in touch with us and we can help you work it out. Whether you have your energy use available or not, you can also take a look at your current energy costs and we can make an educated estimation of the size of energy system you would need.

Below is a handy chart with recommended solar energy system sizes based on energy costs per month.

A little extra: If your business will need more than a 30kW solar energy system you will need planning permission, so keep this in mind.
