    Solar energy

    Online calculator will help you calculate the energy received from solar panels and also suggest which solar panels and battery packs you need.

    Initial data for direct current consumers DC
    Voltage, V Maximum device power, W Number of devices Duration of operation per day, Hours Duration of operation per week, Days W x Hour per week, Wh/Wh
    Total
    Taking into account the compensation coefficient 1.2
    Initial data for alternating current consumers AC
    Voltage, V Maximum device power, W Number of devices Duration of operation per day, Hours Duration of operation per week, Days W x Hour per week, Wh/Wh
    Total
    Taking into account the compensation coefficient 1.2
    Initial data for final calculation
    * Insolation coefficient is selected according to map in accordance with the territory
    ** Temperature coefficient is selected according to the ambient temperature in the table on the right
