If you were looking for a vendor that could install a large system for a school , would you insert the information like you would for a home. In other words are there certain installers that do this specialized work?

I would call Energy Sage to ask, they are very helpful.

Many companies that do residential also do large commercial installations and usually showcase those installations on their websites.

The company I selected had recently finished a big job such as yours. I would say enter the info and see if you get results. Worst case scenario you get no quotes. Nothing to lose.
