What is solar battery technology?
Solar battery technology stores the electrical energy generated when solar panels receive excess solar energy in the hours of the most remarkable solar radiation. Not all photovoltaic installations have batteries. Sometimes, it is preferable to supply all the electrical energy generated by the solar panels to the electrical network.
Why do PV systems need a battery?
Battery. The battery stores electricity for use at night or for meeting loads during the day when the modules are not gener-ating sufficient power to meet load requirements. To provide electricity over long periods, PV systems require deep-cycle batteries.
Why do solar panels use batteries?
The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.
How does a photovoltaic storage system work?
So when it comes to photovoltaics with storage, the system usually involves an electrochemical storage unit such as a battery. The functional principle is quite simple. The PV battery storage system stores the electrical energy, similar to a rechargeable battery, until a demand arises in the household.
How does a PV battery storage system work?
The PV battery storage system stores the electrical energy, similar to a rechargeable battery, until a demand arises in the household. It then passes that power on to the connected consumers (light, refrigerator, TV system, etc.). In detail, this means that when the sun's rays hit the photovoltaic modules, they are converted into direct current.
What types of solar batteries are used in photovoltaic installations?
The types of solar batteries most used in photovoltaic installations are lead-acid batteries due to the price ratio for available energy. Its efficiency is 85-95%, while Ni-Cad is 65%. Undoubtedly the best batteries would be lithium-ion batteries, the ones used in mobiles.
