How We Work

Our Approach is Simple and Clear

01

Consultation

We start by reviewing a recent electricity bill to understand your energy consumption.  We’ll model a system based on your needs.

02

Planning

Once you sign your proposal, we’ll schedule a site visit and engineer a detailed design of your system using drone footage and specialized software.

03

Permitting

Our team coordinates with your utility and local ordinances to get all of the permits and paperwork you need squared away.

04

Installation

We’ll coordinate with you to find the best time to install your system. An average residential system takes 1-3 days to install.
