The number of solar panels needed for a house in Malta can vary greatly based on the energy consumption of the home and the wattage of the solar panels. The average home in Malta consumes around 6000 kWh per year. A typical 4kWp PV system consisting of 7 solar panels of 570W each or 8 panels of 505W each would offset this consumption. However, this is just an average estimate, and the actual number will depend on the exact solar panels used, their efficiency, the amount of sunlight in your specific location, and your personal energy usage.
