Our Work Process

Facility Audit

Additionally, as part of our on-site Energy Audit we'll discuss a comprehensive plan for implementing an energy conservation program that will help make your business more energy efficient.
Project Overview
After our on-site Energy Audit is completed, you will be presented with a comprehensive "Renewable Energy Proposal" for your business that achieves your energy independence goals. The Renewable Energy Proposal consists of a system design, equipment list and specifications, energy cost/benefit analysis, and all associated renewable energy and energy efficiency rebates, incentives and tax credits. Once you approve our proposal, we will execute a "Renewable Energy Agreement" that provides our contract terms and conditions, project scope of work, rebate and incentives forms.

Additionally, Energy Project Manager schedules all building, electrical, utility permits inspections and system commissioning as part of the project timeline. Our professional system installation crews arrive each day on time, conduct their work in a respectful and courteous manner, and always leave work sites clean every evening.
