The REopt™ Lite web tool helps commercial building managers optimize solar photovoltaic (PV), wind, and battery storage systems for financial savings or energy resilience.
The tool lets users:
- Evaluate the economic viability of grid-connected PV, wind, and battery storage at a site
- Identify system sizes and battery dispatch strategies to minimize energy costs
- Estimate how long a system can sustain critical load during a grid outage.
REopt Lite offers a no-cost subset of features from NREL's more comprehensive REopt model. REopt Lite also offers an application programming interface (API). Send questions and tool feedback to REopt@nrel.gov.
