System Sizing
Grid-Tie system sizing begins with a quick analysis of your past electricity bills. This information allows
you to see how much electricity you use on an average day. Once your average daily usage is calculated,
we can perform an analysis of your site to determine how much solar radiation you receive. With these
two pieces of information, you can get a rough idea of the system size required to meet all or a portion
of your electricity needs with solar. The final step allows us to factor in equipment efficiency in order
to fine-tune the system size.
