The particularity of this kind of system relies on its capacity to store and manage energy so as to use the most appropriate source in a determined moment, ultimately aiming to reduce costs and optimize supply. For instance, in a community with solar panel facilities, a wind turbine and a local grid connection, during a high radiation high wind speed day the system will use only solar and wind energy and charge the batteries in case of available surplus. At night, when batteries are low in charge, the system will use energy from the local grid. With the electric micro-grids designed by Waira, on grid and diversified facilities can be installed, ensuring a significant and sustained reduction on monthly energetic costs.
In addition, electric micro-grids constitute the ideal solution for rural electrification, using solar and wind energy efficiently to maximize production and improve life quality in remote locations.
