The challenge: following PV production in real time

For the past two months, RY3T has been working together with advisor Michael Schmid on the NOVA control system. The goal is clearly defined: the NOVA should follow PV production as quickly as possible. When there is more sun, it raises its computing power. When clouds roll in, it powers back down, ideally without delay.

Minutes became seconds

And it works, getting better all the time. In the beginning it still took minutes for the computing power to adjust to PV production. Now it happens in just a few seconds. That makes the NOVA not only far more flexible, but also noticeably more efficient.

Why response speed matters

PV power fluctuates heavily. A single cloud, a brief change in the weather or an additional appliance in the house, and the available surplus shifts. That is exactly why the NOVA has to react fast: so that as little PV surplus as possible goes unused or flows into the grid at poor terms.

Key point

The faster the control follows the surplus, the less solar power is lost unused, and the more value stays in the building.
