@garymatt, who said "6 Kilowatts is my average monthly usage. This means to my surprise I have a comfortable margin if I put in a 10 Kw system."
If you mean "6 kwh (kilowatt hours) a day" on average, then you can probably get by with less than 6 kw of solar, as the panels produce 4-6 hours x their rating each day, so on a sunny day could produce up to 36 kwh, if needed.
If you're off-grid, oversizing your system will ensure you have enough power on rainy days. But if you're on-grid, you can just draw from the grid and I don't think you can ever get payed for excess power generated.
