What kind of family?You can figure out how much electricity you use every day,and then calculate it yourself.My family,for example,has about 20 kilowatt hours a day.24 hours a day,but the average sunshine in my place is 6.6 hours.This requires solar panels to provide 20 kWh of electricity in 6.6 hours.That is 3.03 kilowatts per hour.Let's call it 3 kilowatts.The highest conversion rate of general solar panels is 22%,and the solar energy is about 1000w per square meter,so the conversion rate of solar panels is about 220w per square meter,equivalent to 0.22kw per hour...3/0.22 is about 13.6 square meters.So my home needs about 13.6 square meters of solar panels.
