I'm in a prescribed northern zone. How does latitude affect solar power and how are these calculations made?

Go on your favorite search engine and look for "off grid solar calculator". It will ask you for your zip code and may ask for your load size. You will then get your minimum number of sun hours for your area.
The calculations are based on your position on the earth. There's probably a table with this data somewhere. I frankly don't know. This is how I sized my system.
I know I use less than 20KWH per day of energy, based on my electric bill. I get more than 4 hours minimum of sunlight per day based on the calculator. This means I need 5KW of solar panels. However, you may need more if you don't have a clear area.
