“…The disadvantage of using this type of resource is that the production of electricity is realized only during the day, the surplus electricity, being stored in batteries or distributed in a larger network but the advantage is that they have long-term use, continuous supply during operation, and costs can be low. [20], [21], [35], [38]- [40], [42], [43] To increase efficiency, photovoltaic panels can be grouped with other types of systems energy producers (wind systems, diesel generators, fuel cell system, electrolysis, battery), thus developing various types of hybrid photovoltaic systems. [20], [21], [24], [27], [30]- [32], [36], [44]- [47] The electrical energy produced by the photovoltaic panels can be used for:…”
