Storage Batteries: How they work

Storage batteries for photovoltaic systems are systems that allow the electrical energy produced by photovoltaic panels to be accumulated during the hours of the day to then be able to use it at times when the panels do not produce energy, therefore during the night or on particularly difficult cloudy days.

By using batteries in a photovoltaic system, you have the possibility of increasing self-consumption, reducing the need to draw energy from the electricity grid, which is therefore an economic saving and greater energy independence.

During daylight hours, when the sun is shining and the photovoltaic panels are producing power, the excess energy that is not immediately consumed is used to charge the battery. Once charged, the battery conserves this energy for later use. When the PV system is no longer producing power, the battery releases the energy to power the utilities.

The sizing of the storage battery is done by associating the power output of the PV system with household consumption habits.
