The sun is not always shining when the electricity consumption is the highest. Therefore, one of the most pressing issues faced by many owners of solar (photovoltaic) panel systems is the storage of the generated electricity.
If it is an office building or an institution where people work every day, then most likely the sun will shine on the photovoltaic panels at the right time.
Right when people work in this facility and, accordingly, consume the most electricity. However, if it is a private house whose residents are at work during the day, then most likely the largest amount of electricity will be consumed in the morning or evening. Namely, in those hours of the day when there is not so much sunlight. Of course, under such conditions, it is useful to store electricity during the day, and use it as needed in the evening, night or morning hours.
Partial independence from centralized electricity suppliers and their networks is good not only because it allows you to save money by producing electricity yourself, but also because in emergency situations an office, house, farm, production plant or institution will not be left without electricity supply. For example, when power lines are repaired or storms and other unforeseen natural disasters occur.
