The latter are the most suitable for photovoltaic systems due to their capacity for repeated charging and discharging. How do lead-acid batteries work? The operation of lead-acid batteries is relatively simple but effective. When the photovoltaic panels receive solar radiation, the charging process begins.
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.
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.
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.
Limited lifespan: Although durable, lead-acid batteries tend to have a shorter lifespan compared to some more expensive alternatives, which may require periodic replacements. In summary, lead-acid batteries are a solid and reliable option for energy storage in photovoltaic systems.
At just 3 kWh per module, the Generac PWRcell is the most flexible and customizable solar battery on our list and perhaps the market. Stack three batteries together for 9 kWh of usable capacity – ideal for Solar self-consumption and light backup – and then add up to three more per cabinet as your storage needs increase.
