Solar precision engineeringEstimate your savings
Homes: you own the system. The PPA with no upfront investment is for businesses only.
1Your consumption
That consumption and that bill do not look like they come from the same statement. Check that both are for the same month — meanwhile we will use a typical rate for your area.
Where do I find the kWh on my bill?Tell us what you have and when you use it, so we know how much of your consumption the sun can cover.
2Your roof
Find your house on the map and click the corners of your roof. It takes a minute and gives us the exact area.
3Your budget
With your budget we design two options: what fits in that figure, and the ideal system with bank financing.
4Fine-tune itoptional
How much you expect your consumption to grow once the solar panels are installed (for example, if you plan to add air conditioning or an electric car). We size the system for that consumption.
%With your NIC or your bill, the estimate is far more accurate.

The engineering of your plant
Solar Wizard: your plant, to the centimetre
This calculator is the first look: it estimates your plant from what you told us and a satellite image. The real project we design in Solar Wizard, the software we built at Mistral, on the 3D model of your site.
| The calculator | Solar Wizard | |
|---|---|---|
| Roof | Satellite image and your measurement | Drone flight and a photogrammetry 3D model |
| Shading | Approximate buildings and trees | Every neighbour, tree and tank, hour by hour all year |
| Modules | One sensible layout | Hundreds of layouts, ranked by energy, cost and mounting |
| Wiring | Estimated strings and tray | Every string per MPPT and the shortest cable route, to the metre |
| Losses | A typical performance ratio | The PVsyst loss chain, link by link |
| Deliverable | A figure to decide on | Drawings, single-line diagram, bill of materials and 25-year cash flow |
What you see in the render (the cable under the modules, a single tray down to the drop, the boards and the single-line diagram) is Solar Wizard in miniature. With the flight, it is done on your real roof.
