EV Charging

Curious about how EV charging can help your project?

EV Charging Use Case Example


The demand for EV charging infrastructure is growing
rapidly. With this, electricity consumption costs and
transformer overloading have become big concerns to
infrastructure owners.


  • Peak Shaving for grid connected chargers
  • Significant bill savings with renewable generation
  • Reduced interconnection bottlenecks
  • Turn key solution with minimum consultations


TROES’ solution is to integrate an EV charging station that combines solar PV system and a battery energy storage system (BESS) to reduce the demand stress on grid and make bill savings by reducing grid usage during peak periods.

The charging station has Level 3 EV chargers that can charge EVs in a short period of time due to high charging power. The power demand of a Level 3 charger is normally higher than 30 kW and in cases above 100 kW as well. So, usage of Level 3 charger during peak hours has significant impact on electricity bills. The integrated solar PV and BESS provides a smart charging solution without overloading the existing system and eliminated the inconvenience of charging EVs during peak hours.

Suppose the system costs US$120,000. With 8 hours of daylight, the charging fee at $0.33/min ($0.4/kWh) and the cost from grid is $0.1/kWh, the annual revenue will be $43,000. In just 3 shorts years, the system has been paid for.
