New SunSat™ Digital Twin makes solar asset management simple


“We are proud that in 2019 again we are standing out with our services and products. We are leveraging our decade long experience in satellite services to derive target production values without the need to install any hardware or ground sensors.” says Nicolas Schmutz, founder and CEO of Reuniwatt.

Reuniwatt’s reliable satellite-to-irradiance based forecast is now provided to the user as a new, highly accurate and cost-efficient supervision tool for performance monitoring. SunSat™ Digital Twin is an innovative solar asset management tool offering a real time health check at a glance, and enabling the asset managers to optimise the yield of their solar parks and improve financial results.

SunSat™ Digital Twin can be applied to single projects or the complete fleet, thus being especially useful for asset managers who want to supervise their portfolio with one single KPI. It provides a comfortable user experience, simplifying monthly reporting requirements by automatically concentrating distributed information into one, and providing independent expert reporting much appreciated by CFO.
