The cost of a home battery depends on the capacity of the battery (kWh), the characteristics and the brand of the inverter used, as well as installation requirements. An existing PV system with a compatible inverter can be retrofitted with a smart battery system for as little as €1,800 after government grants.

 The average payback period or return on investment (ROI) for most battery systems in Malta is around 3 – 5 years. Households with higher energy consumption tend to recoup their investment in solar battery much faster due to avoidance of higher import tariff bands. Indeed we had customers who managed to recoup their solar battery investment in less than one year!

For most people, independence and continuous availability of power supply is by far the greatest benefit of owning a solar battery.
