How to use the calculator

“Every home, shop, or factory is different! Use these easy steps to get a quick idea of the best solar setup for you. Don't worry if you skip something, you can always call us for free to get any help”
step 1
Share Your Electricity Use (in Units or kWh)
Look at your last few electricity bills (best if from 6-12 months). Add up the units you use each month—most homes need 100-400 units per month. This tells us how big your solar system should be to cut your bills!
step 2
Tell Us About Your Roof Space (in m²) and Budget
A bigger roof means more solar panels and bigger savings! Don't know the size? Just measure with a tape or count the floor tiles (one tile is usually about 1 m²). Mention the south-facing, unshaded area available for more accurate answers. Share your budget too—we'll suggest something that fits without breaking the bank.
step 3
Pick Your Type and Location
Are you a home user (Domestic), shop owner (Commercial), or factory (Industrial)? Choose that, plus your state. This helps us find the best subsidies and panels for your area—saving you more money!
step 4
Add Your Daytime Power Use and Bill Rate
What % of your electricity do you use from 10am to 3pm? (Think fans, lights, or machines during sunny hours.) This cuts down on battery needs and costs. If your bill has Time of Day (ToD) charges, check there—or just guess by adding up what you run in those hours. Also, enter your average cost per unit from your bill.
step 5
Hit "Calculate" and See the Magic!
You'll get a custom solar plan with savings, how quick it pays back, and tips. It's a great start—book a free expert visit for the perfect fit!
