This is a very useful, practical article (ignore the ‘Error’, the link works) that explains what a 10kW solar system can run in your home. 10 is large, many have less than that, but because the cost of panels has plummeted in recent years people are installing bigger systems. (Ours is 11.78kW.) You’ll pay it off in 3 to 5 years, at most (and you can get it on an interest-free loan anyway from installers.) And then have several decades of it making you money. It’s always better to go as large as you can afford, because it’s more expensive to add more capacity later. And with EVs becoming the dominant car form in the next few years, you can use the excess to charge your car as well.
