How Many Panels Fit On Your Roof?
That depends completely on the size of your roof. You can try to fit as many panels on your roof as possible with SunSPOT’s free Map My Roof tool.
SunSPOT’s Map My Roof tool let’s you fit panels on your roof to see how big of a system you could fit.
Enter your address, choose Map your roof, follow the instructions and place panels on the suitable sections of your roof. You can move and rotate the panels to test different layouts and see approximately how many will fit.
Once you have finished mapping your roof, take note of the total solar system size in kilowatts (kW).
Take note of this system size and try it out in SolarQuotes’ solar calculator to find out how much this can save you.
Calculate Your Solar Savings And Payback
Enter that system size into our Solar & Battery Calculator.
Then, add a system price from the range that SunSPOT estimated:
Add your postcode, the direction of your panels, and your electricity usage. Then click “Calculate Savings”.
You should then see
- How much electricity the system could generate
- How much it could reduce your electricity bills
- How long the system could take to pay for itself
- Whether adding a battery may be worthwhile
You can also try a few different system sizes to compare the results before deciding how much solar to install.
These tools provide estimates only. A solar installer will need to inspect your property and confirm how many panels can safely and practically fit on your roof.
If you want a trustworthy installer to come inspect your property, we can get you quotes from up to 3 solar installers who have been thoroughly vetted.
