WHAT WE DO

CS Energy’s solar and energy storage systems are designed to balance size, energy production and cost to generate the highest returns for our customers. We optimize each system - constantly evaluating capex, opex, and system production to determine the best overall solution.

Engineering

CS Energy’s procurement team ensures our customers get high quality equipment at the best prices delivered on-time to their projects. We manage the process seamlessly, from supplier evaluation and solicitation to equipment manufacturing, delivery and installation to warranty and commissioning.

Procurement

CS Energy’s roots are in construction. That means we know how to execute projects in the real world – on time and on budget. We deliver certainty to our customers, ensuring our projects always meet their completion dates and exceed their performance standards.

Construction

CS Energy partners with clients early on, helping them make good decisions throughout the development process to maximize project value and shorten permitting, interconnection, and construction timelines.
