More panels, less batteries
The perpetual issue in designing a battery's base system is how to charge the battery bank at 100% capacity, preferably every day, but at least once a week. Problems arise when there is not enough sun to meet the daily load, and after a few days, the battery has fewer opportunities to fully fill.
Whenever the budget allows, it can be beneficial to oversize the photovoltaic installation. During sunny weather, the modules will stop charging the battery earlier in the day, but during periods of overcast weather, there will be more PV output to power the batteries and less reason to power the generator.
With a larger array, the specification of a smaller battery bank becomes possible because it is also more likely to be fully charged on a regular basis. If the loads can be coordinated to operate during the day, while the photovoltaic array is producing, a smaller battery capacity can be used successfully.
With the price decrease of modules significantly in recent years, and increased battery prices, the increase in PV array size is feasible for more system owners. In addition, bypass loads can be used to take advantage of excess PV system output on sunny days.
