An average 8 kw solar system costs 15 000 and generates 11 000 kwh annually or 880 to 1 100 worth of energy.

Considering 6 peak sun hours per day and 300 watt panels you need 16 to produce 700 kwh each month. For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. In the example above you would need 24 solar panels to account for 80 of your average consumption 29 6 kwh daily usage divided by 1 24 kwh per panel. 250wp dc in controlled conditions.

So take 900 kwh and divide by the amount of kwh one solar panel produces over the course of a month 30kwh and you get a 30 panel installation. Again though these are just rough estimates.
