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.

The greatest threat to our planet is the belief that someone else will save it.

Our model

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.

Fast and accurate calculatorsWe have created the most comprehensive online solar calculator tool in Australia. It’s free for everyone to use.
A reliable knowledge baseWe publish ad-free guides and articles to support you on your journey – from initial discovery, to the installation of your solar system.
Personalised quotesOur quote service connects you with reputable solar companies. We hand pick every installer we work with, and there’s no obligation to accept any of your quotes.

Our installers

Purchasing solar can be a big decision, but we’re here to make it easier. That’s why we do the hard yards finding the best installers for your needs.

We’re fussy about the installers that we arrange to provide quotes. In fact, we decline over 75% of all installers that wish to join our partner program.

We analyse each company's installation practices, warranties, pricing, product quality, CEC accreditation, and time in business. When you source quotes through us, we match you with the companies best suited to your requirements.

At the end of the day, we're here to help you achieve a quality system that saves you money and reduces your emissions.

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.
