How Accurate are our solar Estimates?

Online solar quotes are not a replacement for a full site survey. However, a well-built calculator using realistic assumptions can provide a reliable cost range and savings projection.

There are a lot of factors that go into determining your final installation cost, some that no online estimate can determine, so we always recommend getting a site survey before moving ahead. The reason we give you an estimated price range rather than a definitive price is to factor in the price variations you will see after a site survey. Where you choose to install your battery and inverter, if you have space in your current fuseboard, and which brands you go for, will all determine your final price.

Our estimates are designed to provide you with a clear picture of what you can expect from your solar PV system to help you determine if solar is worth considering for your home. We have gone to great lengths to make sure that our estimates are helpful to you. From using real historic weather data from your actual location, to giving you customisation of your battery size and panel type. This is an estimate that you can trust.

What Determines your solar quote

Several key factors influence the cost of your solar PV system and the financial savings you can expect from it. Check out the information below to learn more about how your roof, its angle, and orientation can affect your installation cost, as well as how your energy usage and electricity tariff determine your financial savings!

Roof Size and Usable Space
The type of roof covering and the number and size of the roof spaces you want to use all impact the complexity of the installation. This can mean a longer installation or additional scaffolding.

Roof orientation and shading
A large, unshaded, south-facing roof is the ideal situation for solar, but most homes don't have ideal conditions. The angle and orientation of your roof and the shade on it are important factors determining how much power your system produces.

Annual electricity consumption
The daily pattern and total amount of electricity you use play a big part in what savings you can expect to see from your solar PV system. Often, if you have higher annual electricity consumption, then solar is a no-brainer for you.
