Solar PV guides, from the first sketch to the files you hand over

Lay out solar panels on the aerial photo: draw or detect a roof and pvSpline fills it with modules as you drag, with your spacing, orientation, obstacles and strings.

Design solar carports and car park canopies: single-slope or east-west butterfly decks, laid out from their real dimensions, previewed in 3D and simulated.

Simulate agrivoltaic arrays, elevated over crops or in vertical bifacial rows: the panels’ yield, beside the ground light, growing-season PAR and shade uniformity.

Design solar water pumping: borehole, river or pressurised network, pump curves from .PMP files, tank and daily water need, simulated hour by hour with the missing water.

Measure solar shading in 3D: pvSpline rebuilds your site from IGN LiDAR (buildings, terrain and trees) and measures far, near and vegetation shading string by string.

pvSpline reads PVsyst component files directly: import .PAN modules, .OND inverters, .BTR batteries and .PMP pumps with no re-entry, then simulate in your browser.

pvSpline draws the single-line diagram of your PV plant from its design, in IEC or IEEE symbols, batteries and microinverters included, and exports it as SVG or PDF.

Size the inverter and the strings of a PV array: cold open-circuit voltage, MPPT window and DC/AC ratio checked on every change, and the clipping shown in the yield.

Size solar PV cables to UTE C15-712-1, NEC or IEC 60364: ampacity with derating, voltage drop and conduit fill, and each cable’s real I²R loss carried into the yield.

pvSpline prepares the Consuel technical file from your PV design: the attestation and SC forms that apply, the values pre-filled and what is left to declare, in one PDF.

pvSpline assembles the déclaration préalable for solar panels (CERFA 16702): plans DP1 to DP8, photos, parcel lookup and heritage check, ready for the town hall.

The performance ratio of a solar plant per IEC 61724-1: its formula, and the loss cascade behind it, from the light on the modules to the energy at the meter.

Simulate solar self-consumption: bill import, typical load profiles, peak/off-peak and Tempo tariffs, batteries and EV charging, across the whole year.

pvSpline turns the simulated yield into NPV, IRR, LCOE and payback, year by year, with French incentives, VAT, IFER, loans, corporate tax and P90 risk built in.

The CRE grid of the EDF OA purchase obligation in force, surplus and full sale, and every S21 period since 2021.

Prepare a CRE solar tender bid: reference price and indexation, the complément de rémunération year by year, and the dossier productible with P50, P90 and ECS.

The carbon footprint of a solar project: CO₂ avoided on the country’s grid against CO₂ embodied in modules, inverters and batteries, with the carbon payback time.

Record a time-lapse of the sun sweeping your solar site in 3D: a fixed view, an orbit or a flight along a path you draw, with the live stats in every frame, up to 4K.

Export your solar site as STL: terrain, buildings, trees and PV modules, in layers for CAD or as one closed solid for a 3D printer, your logo engraved underneath.
