Each of my panels has a theoretical capacity of 390 Watts per hour. So 4kwh in a day seems very feasible. My panels are certainly not the cutting edge of technology!
Your 390W is if the sun is in the zenith and hitting your panel at right angle. Also, are you sure your panel is 1m^2?
Fair point about the size of my panels. I think they are larger than 1m^2!
