Our Solar Calculators

Solar Income & ROI calculator

With this calculator you can estimate the income cost of a new system, and also compare it to an existing, older solar system to see if it's worthwhile to upgrade.

Step 1 - Your Area

Step 2 - Your Current Bills

Base estimate from my

OR

Base estimate from my

Daily Average
info

info
info
This is not a valid integer! Please enter your dailyUsage!
info
This is not a valid integer! Please enter your Electricity Consumption!
info
${[{ formData.purchaseRate }]} per kWh
info
${[{ formData.buybackRate }]} per kWh

Step 3 - Lifestyle

Your solar system will generate electricity all day. Your electricity consumption will sometimes be more than your system generates and sometime less. When it is less you will export electricity and potentially get a feed in tariff paid. Please estimate how much of your solar system generation will be consumed within your house vs solar electricity being exported.

{[{ formData.lifeStyleData }]}
Mostly used during day
Mainly use solar electricity Mostly out during day
Mostly export and sell solar electricity

Step 4 - Return on Investment
