PV

DC and AC production, multi-array layouts, the built-in module catalogue, and inverter sizing.

BREOS uses pvlib for solar position, irradiance transposition, cell temperature, and PV performance model pieces. The functions below document the BREOS wrapper surface; for PV modeling background and parameter references, start with the pvlib documentation and the project Resources page.

Production

breos.solar.calculate_pv_production_dc(...)	Calculate PV DC production from weather data (fixed-tilt array).
breos.solar.calculate_pv_production_ac(...)	Calculate PV AC production from weather data.
breos.solar.calculate_multi_array_production(...)	Calculate combined DC production from multiple PV arrays.
breos.solar.dc_to_ac(dc_power, pv_peak_power_w)	Convert DC power to AC power through inverter.

Module catalogue

A built-in dictionary of PV module electrical parameters lives in breos.pv_modules.MODULES. Use the accessor functions below rather than indexing the dict directly — get_module raises a clear error on unknown keys, and list_modules returns the available keys.

breos.solar.PVModuleParams(Mpp, Vmp, Imp, ...)	Parameters for a PV module.
breos.pv_modules.get_module(name)	Get a PV module by name from the catalog.
breos.pv_modules.list_modules()	List all available module names.
breos.pv_modules.get_module_info(name)	Get a formatted string with module specifications.

Geometry

breos.solar.estimate_optimal_tilt(latitude)	Estimate optimal fixed tilt angle based on latitude.
breos.solar.default_azimuth(latitude)	Return the optimal default azimuth based on hemisphere.

Inverter

Common inverter configurations live in breos.inverter.INVERTER_PRESETS. Use get_inverter_preset to look one up by key.

breos.inverter.InverterConfig([...])	Inverter configuration parameters.
breos.inverter.get_inverter_preset(name)	Get a pre-defined inverter configuration.
