During the day, the sunlight that falls on the panels is absorbed and converted into electrical energy, direct current (DC).The inverter captures the direct current and transforms it into alternating current (AC) that can be consumed in the home or business. The alternating current (AC) is then consumed in the home or business, generating energy for lamps, household appliances and others. The surplus energy generated is injected into the distribution network, generating credits that can be used for up to 60 months. When no energy is generated (e.g. at night) or when consumption is greater than that generated, the electricity supplied by the distributor is used. ** 1 - Photovoltaic modules 2 - Charge controller 3 - Inverter of-grid 4 - Battery **
