We investigate hybrid quantum neural networks for time-series forecasting of photovoltaic power and introduce two architectures.

The second, a Hybrid Quantum Sequence-to-Sequence model, once trained, it predicts power for arbitrary forecast horizons without requiring prior meteorological inputs and achieves a 16% lower mean absolute error than the best baseline on this task.
