Cost per watt, explained in plain English
Every solar quote has two moving parts, and cost per watt collapses both into one comparable number.
How big the system is
How much it costs
What the whole job costs you, installed.
A 10 kW system, in watts.
The one number that lets you compare quotes fairly.
It strips out size, so you can put a 6 kW quote next to a 12 kW quote and actually see who is charging more. If you learn one piece of solar math before you shop, learn this one. It is how I would shop if I were the customer.
