A schematic diagram of the solar battery charging circuit. The battery is charged when the voltage of the solar panel is greater than the voltage of the battery. The charging current will decrease as the battery gets closer to being fully charged. This is just a simple circuit, and there are many other ways to charge a battery from solar power.
The choice of charging strategy will depend on the specific requirements and limitations of the off-grid solar PV system . Factors such as battery chemistry, capacity, load profile, and environmental conditions will all influence the optimal charging strategy .
The key function of a battery in a PV system is to provide power when other generating sourced are unavailable, and hence batteries in PV systems will experience continual charging and discharging cycles. All battery parameters are affected by battery charging and recharging cycle.
All battery parameters are affected by battery charging and recharging cycle. A key parameter of a battery in use in a PV system is the battery state of charge (BSOC). The BSOC is defined as the fraction of the total energy or battery capacity that has been used over the total available from the battery.
This paper concludes that the choice of charging strategy depends on the specific requirements and limitations of the off-grid solar PV system and that a careful analysis of the factors that affect performance is necessary to identify the most appropriate approach.
If the PV system is grid-connected, batteries can reduce the fluctuation of PV output or provide economic benefits such as demand charge reduction, capacity firming, and power arbitrage.
