If you have a 5 KW system i.e. 5000 watts of PV panels, in one hour you will make 5 KWH. in 8 hours you will make 40 KWH. So in the 12K system that solarman is selling, the array will produce 700 watts in full sun. That will be .7 KWH in one hour. So I'm guessing he is calculating for about 4 hours worth of full sunlight to get the 2.24 KWH per day. If you look on your helco bill it tells you how many KWH per day you use on average. So the less you use the smaller your system will need to be. But believe me, too much is always better with solar. I think today we made over 30 KWH at home.
