Free solar tools
Free solar tools
We have partnered with PV Fleet, and they are providing their solar calculators to Solar Geeks visitors free of charge. Six tools to work out which way your roof faces, how steep it is, how many panels will fit and what each direction is actually worth, straight from your browser. No signup, nothing to install, and they work fine on a phone.
What you can use
The calculators
Every one of these is free and opens in a new tab on the PV Fleet site.
Roof Azimuth Calculator
Type in an address, draw a line along the ridge of your roof on the satellite photo and you get the exact azimuth from true north. Works for any address in the world.
Roof Tilt Calculator
Take a photo of your roof, line up the two guides and you get the tilt in degrees plus the pitch ratio. The photo never leaves your phone.
Solar Panel Angle Calculator
Enter the direction your roof faces, the tilt and your postcode, then see how much of the ideal yield that roof actually captures.
Roof Area & Panel Calculator
Draw your roof on the satellite map and get the usable area, how many panels will fit and the system size in kW.
Solar Panel Orientation Comparison
Compare north, east, south and west facing panels at the same address, or set your own direction and tilt. You get the output for a typical year, for each season and for a clear day.
Latitude & Longitude Finder
Turn an address into GPS coordinates, or drop a pin on the satellite map. You get decimal degrees and DMS, with a copy button for each.
Our monitoring partner

These tools tell you what your roof can do. If you want to know what that is worth in dollars, we run fixed price feasibility studies with real numbers for your site and your tariff.
