Nigeria solar pump: keeping water flowing through three cloudy days?

The farm well yields 8 m³/h, with a 5.5 kW solar pump for 120 acres of vegetables.
Three cloudy days in the irrigation season left only one day of storage.
Batteries or a bigger tank: which pays?

Enlarge the tank first, sized for two days of use; cheaper than batteries and longer lasting.

Irrigation demand is low on cloudy days anyway; a diesel backup pump is cheaper than a battery bank.

Batteries sized at 30 kWh a day are costly; unless you irrigate at night, skip them.
