Longitudinal Dataset of Net-load, PV Production and Solar Irradiation from Madeira Island, Portugal

The PTProsumer dataset is a collection of high-resolution residential photovoltaic (PV) production and net-load measurements from 24 prosumers - entities that both produce and consume electricity, including households and small commercial buildings - on Madeira Island, Portugal. The dataset covers monitoring periods ranging from 3 months to 5 years, with measurements sampled at a 1-second resolution, resulting in approximately 3.89 billion data points. PV production and electricity consumption are provided as separate signals, enabling detailed analysis of local energy flows. It is further enriched with 1-minute resolution solar irradiation estimates from the Copernicus Atmosphere Monitoring Service.
