What is energy storage?

Anyone who has ever used a battery, accumulator or power bank has encountered an electricity storage device. An energy storage device for a photovoltaic installation works on a similar principle. It is an advanced device that collects and stores electricity, allowing it to be used in the future. When the PV installation produces more electricity than the actual demand of a home or business (this usually happens during very sunny days), its surplus goes to the connected energy storage device. The energy stored in the storage device can be used at peak times, e.g. in the morning and evening. The energy storage device consists of a control module and battery modules.

Energy storage – benefits in many areas

Energy storage allows for the full use of the potential of implemented photovoltaic installations. Electricity is not wasted, and the prosumer - in addition to real savings in the home or company budget, gains energy independence and a sense of security in emergency situations. The level of energy self-sufficiency can exceed even 70%. The device is an ideal solution for investors with a small area for the installation of PV panels. Its connection translates into an increase in the power of the installation. Another significant benefit is the stabilization of the grid. The energy storage is a remedy for the installation switching off due to too high voltage from the power grid. Importantly, the regulations coming into force promote energy storage, so you can count on a much faster return on investment. Co-financing under the government program "Mój Prąd" is up to 50% - also in the case of completed and connected to the grid investments. It is worth knowing that having an energy storage may soon become mandatory.
