ソーラーパネル計算機

Solar Panels Calculator compared with PVsyst, HelioScope, SAM and PVWatts
Solar Panels Calculator (PVGIS API 5.2)	PVsyst	HelioScope	SAM	PVWatts
Tools and outputs: Endpoints for grid-connected and tracking PV (PVcalc), off-grid PV (SHScalc), monthly and daily radiation, hourly radiation series, typical meteorological year and horizon profile. Output comes as CSV, JSON, or EPW for the TMY tool.	Tools and outputs: Modelling of system type, weather data, geometry and loss assumptions for PV projects, aimed at bankable yield studies.	Tools and outputs: Design of commercial solar systems with production estimates and system size optimisation. Lenders cited by the vendor use its estimates in underwriting.	Tools and outputs: Time-series simulation of power system performance together with annual pro forma cash flow, so it covers techno-economic questions for renewables beyond PV yield.	Tools and outputs: Simplified estimate of PV energy production. Version 8 adds bifacial modules, monthly soiling and snow loss inputs and an optional albedo input.
Weather and radiation data: Selected with the raddatabase parameter: PVGIS-SARAH3 for Europe, Africa and Asia, PVGIS-NSRDB for the Americas between 60 N and 20 S, and PVGIS-ERA5. COSMO and CMSAF are deprecated.				Weather and radiation data: NSRDB PSM V3 typical meteorological year datasets (tmy-2020 and the Himawari TMY) replace the older 2015 NSRDB sets.
ライセンスとコストモデル： Public web service with no stated fee on the API page. Only GET requests are accepted and the rate limit is 30 calls per second per IP address.	ライセンスとコストモデル： Paid annual subscription. A 30-day evaluation exists, with generic components and an EVALUATION label on reports, according to a third-party review.	ライセンスとコストモデル： Commercial product of Aurora Solar. A review site lists no public pricing.	ライセンスとコストモデル： Free and open source under the BSD 3-Clause licence, with source code on GitHub.	ライセンスとコストモデル： The page states the model may be used for any purpose, and that NREL gives no support, consulting or training.
Platform and integration: Web API for scripts and applications. AJAX calls are blocked by the CORS policy, so browser pages need a server-side proxy.	Platform and integration: Windows workstation software that cannot run through a Windows Remote Desktop client. A separate command-line product exists for server runs.	Platform and integration: Web-native platform.	Platform and integration: Desktop application written in C++ with wxWidgets.	Platform and integration: Web calculator with an API now at version 8.
Version and status: PVGIS 5.3 and 5.2 are served at versioned API paths. The unversioned path serves 5.2 for a limited period, and access to 5.1 has been removed.	Version and status: PVsyst 8 is the current professional release listed on the vendor shop.	Version and status: Aurora Solar announced the acquisition of developer Folsom Labs in August 2021 and presents HelioScope as part of its offer.
