Gallery Box Meteoptim 1


One of the key issues to for the development of domestic solar energy is intermittency of the production, combined with a variable intra-day price of electricity. Management of the domestic hot water tank is a typical example. Box Meteoptim monitors solar home installations and optimizes self-consumption of locally produced energy. This smart box, connected to your solar installation allows you to 1) check out, day after day, that the solar production is in accordance with the day's weather, and alerts you on your smartphone in the event of a problem; and 2) to control the electric supply of your hot water tank, ensuring that it is maximally heated by the sun, and that your particular needs are fulfilled. Indeed, hot water tank is not only a major home consumption item, it is also the first storage device of each house's energy. Its algorithms use weather forecasts and rely on Artificial Intelligence, making the Solution compatible with solar thermal, photovoltaic or hybrid panels, whatever the manufacturers, and automatically adjust to the family's hot water consumption's habits. Increasing by 30% your self-consumption of solar energy, this easy-to-install box ensures the profitability of your solar investment.
