A group of ISI Solar employees meet around a large wooden table. They are all looking toward the back of the table where a man points to a large screen on the wall. "LEAN" is spelled out on the screen and it looks like he is doing a training on best practices.

Lean Construction

We practice all the concepts of LEAN construction. Plan your work – work your plan safely. It is that simple. There is colleague buy-in throughout the organization with best practice and lessons learned at the forefront of every decision. We pool our information through coordinated meetings and promote knowledge transfer from department to department horizontally and vertically. We have also adopted the practical concept that none of us are as smart as all of us.

Integrity

Integrity is a principle. Always tell the truth. This is a concept that is driven into all thought processes throughout the ranks whether it is engineering, procurement, or construction. If trust is not the foundation of a relationship, there is no relationship.

Total Transparency

Communication and transparency with our customers is paramount. Our customers have the unique advantage to login to see into our individual projects through access to our Enterprise Resource Planning (ERP) and Customer Relationship Management (CRM) software. Customer visibility extends to schedule updates, daily progress photos, billing status, and more. We are committed to strategic improvement of these resources to meet both the evolving needs of our team as well as our clients.
