Resources

This page collects external documentation and data sources that are useful when preparing BREOS inputs. Inclusion here is not a redistribution grant or endorsement. Always review each source’s current license, API terms, citation requirements, and commercial-use limits before using it in a project.

PV models and component data

Resource	Use it for	Notes
pvlib Python documentation	Solar position, irradiance transposition, PV temperature, and PV performance model references.	BREOS uses pvlib internally for PV calculations.
pvlib retrieve_sam	Accessing module and inverter parameter tables bundled with pvlib.	Useful when comparing BREOS module entries against SAM/CEC style data.
NREL SAM photovoltaic module help	Understanding CEC, Sandia, IEC 61853, PVWatts, and user-entered module models.	Good background when deciding which module datasheet parameters are needed.
Manufacturer datasheets	Final project assumptions for module power, temperature coefficients, dimensions, and inverter ratings.	Prefer datasheets for real designs; catalogue entries can lag current products.

Load profiles

BREOS bundles only demandlib-derived H0 example profiles. Other RLPs should be provided locally through rlp_directory; see Load Profile Data.

Resource	Use it for	Notes
demandlib documentation	Generating synthetic German standard demand profiles.	Source basis for the bundled example H0 profiles.
BDEW Standardlastprofile Strom	German standard load profile references.	Public download page does not by itself imply package redistribution rights.
E-REDES Consumption and Loss Profiles	Portuguese BTN A/B/C and related consumption/injection profile files.	Use as external user data unless redistribution permission is confirmed.
E-REDES Open Data Portal	Portuguese distribution-grid open datasets.	Check dataset-specific terms and attribution requirements.
Red Electrica consumption profiles	Spanish final consumption profiles used for non-hourly metering settlement.	Use as external user data unless redistribution permission is confirmed.

Weather and solar resource data

Resource	Use it for	Notes
PVGIS online tool	EU/JRC solar resource data and PVGIS workflows.	BREOS can fetch PVGIS TMY data through pvlib; acknowledge PVGIS/JRC where required.
PVGIS data download	PVGIS geodata and source/citation details.	Review the source-specific acknowledgement text.
Open-Meteo Historical Weather API	Historical weather/reanalysis variables such as temperature, wind, and solar radiation.	Review current pricing/terms for commercial or high-volume use.
NREL NSRDB API	Satellite-derived solar radiation and meteorological data, especially for U.S. and covered regions.	Requires an API key for downloads.
Meteonorm API documentation	Licensed TMY, climate, forecast, and observation data workflows.	Commercial product; use with an appropriate Meteonorm license/API key.

Project assumptions to document

For reproducible studies, keep these alongside the BREOS config:

• Weather source, year range, API provider, and API key/account used if applicable.

• Load profile source, license/permission, annual consumption, and scaling method.

• PV module and inverter datasheets, module count, layout, tilt, azimuth, and tracking assumptions.

• Battery datasheet or modelling assumptions, including usable SOC window, efficiency, chemistry, and degradation model.

• Cost, tariff, export-price, inflation, discount-rate, and emissions assumptions.

• BREOS version and any local code changes.
