These types of installations do not need to be connected to the electrical distribution network, since they have a set of batteries capable of storing the energy generated during the day to be consumed at any time, being a totally independent and autonomous system, commonly used in isolated areas, or places where there is no access to the public network.
The components of this type of system consider four elements: solar panels, inverter, and batteries, for this reason, their costs necessarily depend on the number of batteries required to store energy. In these systems, the design is very important, since the current and future electricity consumption that will be required to be covered instantly and the days of backup sought must be correctly quantified, a situation that will depend, among others, on the radiation of the place, season of the year. , shadows of the place, etc..
