By installing Gas appliances most household peak kilowatt consumption should be reduced to less then 4000 watts during normal usage.
Average household consumption is around 1100 watts with fridges and the pool pump running during the day. The only high consumption appliances should be a Dish washer and Tumble dryer with peak usage around 2500 watts.
By reducing the average kWh consumption from around 40 to 24 kWh per day. This will result in a Solar system to be installed with a 21 to 26 kWh per day to fully run off-grid most times of the year.
