REopt Lite

The REopt™ Lite web tool helps commercial building managers:

  • Evaluate the economic viability of grid-connected PV 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.
