Why retrofit a PV storage unit?
As feed-in compensation has faded more and more into the background as a source of income for photovoltaics, the focus is increasingly shifting onto boosting your self-consumption of the PV electricity in order to make a profit. The electricity generated yourself from your roof needs to be used even more efficiently.
For this reason, many operators reach their limits without retrofitting a photovoltaic storage unit. During the day, when most electricity is produced, most people are working. Time switches or Smart Home systems can only use a part of the generated electricity immediately. In the evening, when the PV system is no longer producing energy because it's dark, additional electricity is purchased from the energy supplier for hard-earned money. This problem can be avoided if the operator has their system retrofitted with a PV storage unit. In this way, electricity can be stored during the day and consumed as required.
