Does the 1000kwh including geyser/s?Our average home consumption is between 900-1000kwh a month. In Dec, the 16*405w JA Mono panels generated 937kwh of solar. Panel total is 6.4kw but often goes up to 7kw in the mornings when it’s a little cooler. 6*us2000 batteries are usually charged by noon. I might be able to add another panel on each string, but I’ve hit the practical limit of roof space. I don’t think there is a thing like too much panels; they are the cheapest expense of the whole system after all. Start with 8 panels on one string and if you get more budget, add another 8 panels later on.
Panels are facing just slightly east of true north, not sure the angle but it’s a pretty standard pitched roof.
Just to give you some perspective.
