Compare Fleets

The rise in EVs and charging infrastructure is leaving many fleet operators wondering how to make the most of their investment.

Comparing different scenarios, vehicles, chargers, and business models for EV charging infrastructure and EVs is unnecessarily time-consuming and cumbersome.

Compare Fleets allows you to investigate and optimize the financial returns with granular details, easily compare total cost of ownership for EV and ICE vehicles and sell your charging solution with confidence.


Timeseries Energy

As renewable energy projects are becoming more hybrid, there is a lack of high-quality data that reflects real world performance.

Engineering teams are missing out on high-resolution energy data based simulations with high accuracy for rapid decision-making and more profitable investments.

Timeseries Energy makes it easy to integrate high temporal solar energy data to your planning and operational optimization of hybrid energy assets.


Host smart
charging stations

Hosting an EV charging station which is actually profitable is rare.

Charging point operators are placing solitary chargers resulting in property owners not getting much value out of these assets placed at their premises.

Be a part of a high-demand network that helps bring new and repeat customers to your location, monitor with ease from the smarthost
