Solar Panel Cost Calculator
Enter a few details about your home to get a personalised savings estimate.
How the calculator works
The calculator gives you a first estimate in about two minutes. It uses five things:
- Your roof. We look at your roof on Google's satellite map. This shows how much sun it gets and how many panels fit.
- How much electricity you use. Pick low, medium or high. Or type in your yearly use in kWh, or your monthly bill.
- The number of panels. We suggest a number based on your use. You can change it.
- A battery, if you want one. Choose none, 5 kWh or 10 kWh.
- Recent electricity prices. We use a recent price for electricity you buy, and a standard rate for electricity you sell back to the grid.
What you get
- The price of the system.
- How much you could save on your bills each year.
- How much you could earn from selling spare electricity.
- Roughly how many years it takes to pay for itself.
We ask for your name and contact details before we show the price, so we can email you a copy.
How accurate is it?
It is an estimate, not a quote. The final price depends on things we can only check at your home, such as your roof, any shade and your fuse board. For a fixed price, book a free survey. We visit, check everything and give you a written quote.
Questions
Do I have to buy anything?
No. The estimate is free and there is no obligation.
Can I use my bill instead of kWh?
Yes. Enter your monthly bill and we work out your yearly use.
What if fewer panels fit than I chose?
The estimate uses the number that fits and tells you.
Do I need a battery?
No. A battery lets you use more of your own solar power in the evening. You can add one in the calculator to see what it would cost.
