Solar Calculator is your companion on the journey to a cleaner, brighter future. Our calculators, tools, and resources will help you every step of the way – from your first question, to your new, greener lifestyle.

Our mission is to enhance
positive change

Despite an abundance of sunshine hours, so little of the Earth's energy requirements is generated from solar power. It's there for us every day, it's free, and it’s far better for our environment than traditional fossil fuel resources.

Solar Calculator is here to help Australian households take advantage of solar energy. We provide the tools you need to make an informed decision and reduce your carbon emissions.

Solar Calculator is an independently-owned business that exists for one reason: to help reduce household emissions.

We do this by providing free tools and direct access to Australia’s best solar installers.

When our website visitors request quotes, we receive a small upfront fee ($30) from each company. We don’t receive any commissions when a sale takes place. This means we can provide a fair and objective service – without adding to the cost of any install.

Our story

Michael Henderson founded Solar Calculator in 2015. When switching his own home to solar, he struggled to find reliable information on the costs, savings, and benefits. So he decided to create a go-to resource for other people in the same boat.

Based in Melbourne, Solar Calculator was founded to provide unbiased and accurate information for all Australians seeking a positive change.

Today, it has evolved into a comprehensive suite of tools and resources, with regular updates and new content.

Our mission remains steadfast: to be a reliable resource that helps Australians move away from traditional fossil fuels and embrace a greener lifestyle.

We’ve helped over 20,512
Australians transition to solar
