59 MWp utility-scale PV plant
Several years of hands-on experience in operation, monitoring, diagnostics and technical development of a utility-scale PV plant.
Field experience meets software development.
We combine hands-on experience with utility-scale PV plants and in-house software development. We don’t just understand the data – we know the plants that produce it.
We know the plant – and we build the software for it.
