Solar Analysis Tools

Pre-construction
Green Button Emulator

Generate synthetic Green Button load data for buildings before meters are installed. Outputs SDG&E XML and CSV formats.

Carport Solar
Dual-Axis Tracker Analyzer

Compare fixed-tilt carport arrays vs. dual-axis trackers by TOU dollar value. Enter any address โ€” pulls live NREL PVWatts data. Supports carport elevation limits.

Commercial Solar
Commercial PV Sizing

Upload a customer's Green Button interval data and a PVWatts 1 kW reference profile to find the NPV-optimal system size. Models SDG&E delivery + CE generation bills, demand charge ratchet, NEM 3.0 export credits, and 25-year savings with utility escalation.

Off-Grid / Island
Off-Grid Optimizer

Size off-grid PV + battery systems against 25 years of NSRDB irradiance data. Worst-window weather survival analysis with bidirectional EV dispatch.

Residential Rates
Rate Engine

Apply SDG&E rate schedules to Green Button interval data. Residential: TOU-DR1, EV-TOU-5, DR-SES, DR โ€” with CARE discount rates. Commercial: TOU-A (energy-only), AL-TOU, AL-TOU-2 with three-part demand charges. Upload a PV file to compute NEM 3.0 or NEM 2.0 solar savings.
