A large solar battery bank size will be best utilized in areas with more cloudy days, while a smaller solar battery bank should be sufficient in areas with prevalent sunlight. However, it's always recommended to size up rather than down.
A typical 40-foot container home uses 15-30 kWh per day, requiring 3,000-6,000 watts of solar panels. Off-grid setups need battery banks sized for 2-3 days of autonomy.
A 20kW solar kit requires up to 1,300 square feet of space. This could produce an estimated 2,600 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the.
