What Happens to Solar Power When Batteries Are Full?

How long does a fully charged solar battery last? The duration a fully charged solar battery lasts depends on its capacity and the energy demand of the appliances it powers. Typically, solar panels can store energy in these batteries to provide power overnight or for 1-5 days, depending on usage patterns and battery size.

How to Calculate the time of Charging and Discharging of battery?

You also need to keep in mind that a battery is not supposed to be "fully" discharged. Typically, a battery is considered "discharged" when it looses 1/3 of its capacity, therefore it only needs 1/3 of its capacity to be fully charged (range of operation). With these constraints and the above values, one gets only one answer, t = 33Ah/10A = 3.3hr
