Utility_7-16_Vs3KP.indd 54 6/30/17 9:45 AM Where do you look to find quality subcontractors?

We self-perform a vast majority of the work related to the installation of a solar PV project. Over the years, we have developed relationships with companies that can perform subcontracting scopes on projects. We use references from vendors, developers, owners and other contractors to develop new relationships with potential partners and subcontractors.
