The potential of every project…
harnessed by a single tool
The browser-based PV studio that runs bankable physics on live PVGIS, Enedis and Open-Meteo data. Solar carports, storage, EV charging, agrivoltaics, floating PV: design them all in one tool. Your site's buildings, terrain and trees are rebuilt in 3D from IGN LiDAR, so shading is measured string by string. Validated since 2024 against more than 50 million real measurements, backed by a transparent publication.
Simulation, visualization, installation: no hesitation.
Nine things you'd otherwise rebuild in spreadsheets or pay for as add-ons.
Bank‑grade finance, built in
The numbers a bank asks for (DSCR, LLCR, P50/P90 exceedance and lender stress tests) are computed alongside the simulation, ready for the loan negotiation.
Live data, site by site
Fresh satellite irradiance for your exact site, soiling driven by live air quality, real snowfall and your customer's actual Enedis metered load, all fetched automatically.
The systems most tools won't model
Floating solar, agrivoltaics, 500× concentration, PV‑fed tramways and rail, east‑west butterfly domes, solar pumping, off‑grid diesel hybrids: all supported natively and modeled in detail.
Your project on the real Earth
In metropolitan France the 3D scene is rebuilt from IGN LiDAR: real roof pitches, terrain, tree canopy. Far, near and vegetation shading are measured in it, each on its own loss line. Import CAD models, export the scene as STL and record flyovers in 4K.
Simulated down to the minute
The full physics chain runs at 1–30‑minute steps with a thermal‑mass cell model. It catches the irradiance spikes and inverter clipping that hourly tools average away.
Storage & EV that pay for themselves
AC‑ or DC‑coupled batteries with four dispatch strategies, real aging physics and demand‑charge savings. In the same simulation, EVs charge from solar first and can power the home in turn.
Every lost kilowatt‑hour, explained
A 50‑stage loss cascade from sun to grid (soiling, snow, mismatch, clipping, wiring and more). Each stage is tagged with its data source, and the whole cascade is rendered as a client‑friendly Sankey infographic.
Point‑and‑click plant design
Click a roof and it traces itself; panels auto‑fill live, strings paint on with a brush and the single‑line diagram draws itself. Then auto‑sizing hunts down the best NPV or IRR.
From simulation to signature
One click builds the branded client PDF, with charts, wiring diagram, bill of materials and 3D renders. The French DP permit bundle and CRE tender dossier are generated automatically too.
Sweep every design. Keep the winner.
Stop guessing the size. Give the Batch tab a power range and your costs, and it sweeps every kWp, varying module, battery and inverter together and re-deriving the cheapest feasible inverter and string topology for every candidate. Each design is scored by the same full simulation and financial model that produces your final report.
The results land in a sortable grid with NPV, IRR, LCOE, payback, performance ratio and yield on every row, plus the DSCR and LLCR roll-ups a credit committee can read. They are costed like the real world: economies of scale, per-inverter step costs, France's 36 / 100 / 250 / 500 kWp grid-connection tiers. One click applies the winner to your project; sensitivity presets and factorial matrix sweeps cover the what-ifs.

Everything it models.
The full inventory, ordered like your workflow: eleven stops from the first area you draw on the map to the report a lender signs.
