By buyer
13 of the 100 products we researched name this buyer on their own site, across 5 categories. Companies originating and financing projects, often selling or handing over before construction.
This is a record of who each vendor says it sells to, not our judgement of who should buy what. It exists because the field separates products that otherwise look identical — one platform sells to utility programme administrators and another to the installers filing into those programmes.
Verified against the vendor’s own pages.
Usually needs
Site selection, yield numbers a lender will accept, and financial modelling that survives diligence. The output is a document someone else underwrites, so the provenance of the weather data and the loss assumptions is the product.
Usually doesn’t
Field apps, crew scheduling and homeowner-facing proposal design. The work ends before the van arrives.
Both boxes are our editorial framing of the buyer type, not a claim about any product. Every statement about a specific product on this page is read from the feature database.
Categories selling to project developers
Categories with nobody addressing them
No vendor in these categories names project developers as a buyer. That is a fact about their marketing, not proof the tools are unusable — but it is where a sales conversation will be hardest.
Alphabetical. Not a ranking — no product on this site is scored, because no verified reviews exist yet.
DNV
Design & simulation · Desktop
DNV's Windows desktop yield-assessment tool for utility-scale PV — irregular terrain, 3D shade, sub-module electrical mismatch, sub-hourly and multi-year simulation, in-app scripting, and cloud-burst calculation — built on DNV's own continual-validation methodology.
Energy Toolbase
Storage & microgrid · Web
A per-seat storage-and-solar economics and proposal tool whose real product is its utility-tariff, net-metering and incentive database, wrapped in a proposal generator.
Arcadia
Weather, tariff & utility data · Web
The US electricity tariff database and rate-calculation engine that sits underneath other companies' solar savings numbers — now sold by Arcadia under the name Signal, with the Genability brand retired from all public marketing but still live in the API hostname.
Google LLC
A metered Google Maps Platform API that returns rooftop solar potential — building insights, flux, shade and a digital surface model — for addresses inside Google's published coverage polygons.
PVcase
AutoCAD-based design software for utility-scale ground-mount solar — terrain-adapted automated layouts, slope and grading analysis, 3D cabling and stringing, BOM and construction-ready CAD deliverables, sold by quote only.
PVcase (incl. acquired Anderson Optimization)
A cloud site-origination platform for utility-scale solar, distributed generation and data-centre developers: parcel search, buildable-area analysis, permitting and environmental screening, and — the part competitors mostly do not have — interconnection capacity and wholesale power-price (LMP) analysis in the same map.
RatedPower (part of Enverus)
Design & simulation · Web
Cloud platform for utility-scale PV, storage and hybrid plants — automated layout and basic engineering all the way to the grid connection point, with substation design, 3D energy yield, CAD deliverables and a PVsyst export, sold on three quote-only tiers.
National Laboratory of the Rockies (NLR) — formerly the National Renewable Energy Laboratory (NREL)
Design & simulation · Desktop
The US national laboratory's free, open-source desktop techno-economic model — PV, CSP, wind, marine, geothermal, biomass, solar water heating and storage, each wired to a full project-finance model (PPA, partnership flip, leaseback, TPO, community solar, merchant plant).
Solargis
Design & simulation · Web
Cloud PV design and energy-yield simulation built directly on Solargis's own bankable solar and meteo dataset — 15-minute time series over 30+ years, a 3D energy system designer, and ray-traced simulation with the Perez all-weather sky model — at a published €12,000 subscription.
Solargis
Site selection & GIS · Web
A browser app for pre-feasibility solar site screening: 30+ validated map layers of solar, meteorological and environmental data anywhere on earth, plus a monthly-resolution PV yield calculator, so you can compare candidate sites and rank them before committing to a real study.
Transect
Site selection & GIS · Web
A US environmental-due-diligence and permitting platform for site selection: it screens a parcel for protected species, waters, wetlands, soils, federal and state permits, local ordinances and community opposition, and returns a Critical Issues Analysis report in minutes instead of the weeks a consultant takes.
UtilityAPI
Weather, tariff & utility data · Web
The customer-authorisation and utility-data-collection layer: it gets a US electricity customer's permission, connects to their utility account, and delivers their meter details, their actual bills and their 15-minute interval usage to whoever they authorised — over a fully documented public API with a fully published price list.
Xendee Corporation
Storage & microgrid · Web
A modular microgrid and DER platform that co-optimises investment and operation with mixed-integer linear programming, sold as three separately priced seats — a proposal tool, a design tool, and a live controller.

Answer five questions →13 of the 100 products we researched name project developers as a target buyer on their own sites, spread across 5 categories. 3 of the 13 with a readable pricing surface publish a price. Verified 28 September 2026.
The data does not answer that, and we will not pretend otherwise. What it shows is that these 13 products sit across 5 categories and that 14 of our 19 categories contain no product addressing this buyer at all — so the practical question is which of those categories your work actually touches.
3 of the 13 products addressing project developers whose pricing surface we could read publish a figure. 3 offer a free tier or a limited free allowance.
