SolareX - Solar Resource eXchange: solar PV resource assessment, MCDA, and site analysis

SolareX - Solar Resource eXchange

A Python library for solar PV resource assessment, irradiance analysis, temperature modeling, shading/bifacial analysis, MCDA site scoring, and capacity factor computation.

Installation

pip install solarex

With optional dependencies:

pip install solarex[era5]    # ERA5 via atlite
pip install solarex[pvlib]   # CEC module database
pip install solarex[all]     # Everything

Quick Start

from solarex import (
    compute_peak_sun_hours,
    compute_gcr_shading_loss,
    compute_bifacial_gain,
    compute_pv_financials,
    SolarFinancialInputs,
)

# Financial analysis
inputs = SolarFinancialInputs(capacity_mw=50, capacity_factor=0.22)
result = compute_pv_financials(inputs)
print(f"LCOE: ${result.lcoe:.1f}/MWh, NPV: ${result.npv:,.0f}")

# Shading analysis
loss = compute_gcr_shading_loss(latitude=30, tilt=25, gcr=0.4)
print(f"Shading loss: {loss:.1%}")

# Bifacial gain
gain = compute_bifacial_gain(albedo=0.25, gcr=0.4, module_height=2.0, tilt=25)
print(f"Bifacial gain: {gain:.1%}")
