The problem with solar energy, which has been transformed using photovoltaic systems for electricity, is the low capacity to accumulate an excess of produced electricity. This excess of electricity we link within the power grid to send outside the building where the energy was produced to be consumed elsewhere. In this way, we achieve the highest possible utilisation of electricity produced within the boundaries of thebuilding itself. One option is to create opportunities to recharge electric vehicles during working hours, at the time when the production of electricity is the highest but the consumption of electricity is not.
