Among the fusion of technologies that make the MiniStor system a reality, the hybrid photovoltaic-thermal (PVT) collectors are sometimes overlooked. However, this renewable energy source is critical in three ways: making the unit work, and doing so efficiently to minimise the electrical consumption from the grid, and then selling back to it. As they did back in 2022, ENDEF made another presentation in this year’s edition of Eurosun, alongside a brand new peer-reviewed paper making the case for a PVT-driven energy system, such as MiniStor, for a residential application.
