When looking for an energy storage system, one of the key decisions will be choosing the right capacity – 5, 10 or 15 kWh? This choice should not be based solely on the capacity of the photovoltaic installation. Two PV systems with identical specifications may require completely different storage capacities if, in one home, most of the energy is consumed as it is generated, while in another the highest demand occurs only in the evening and at night.<\/p>\n

When selecting the capacity of an energy storage system, the most important factors are therefore the amount of surplus energy generated by the photovoltaic installation, electricity consumption outside peak production hours and the purpose the battery is intended to serve. A different capacity may be appropriate if the main goal is to increase self-consumption, another if the aim is to reduce electricity purchased from the grid, and yet another if the storage system is also intended to provide backup power.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
