Commercial Solar Design & Engineering

Every successful solar project begins with thoughtful design. At CitiGreen, our engineering process is built around one objective: creating commercial energy systems that deliver long-term financial value while meeting the technical requirements of your facility, utility, and operations. Before construction begins, we evaluate your property, energy usage, structural conditions, electrical infrastructure, and financial objectives to develop a system tailored specifically to your business.

Our Design Process

01

Energy Analysis

Every project begins with a detailed review of your historical electricity usage. By analyzing utility bills, demand charges, operating schedules, and seasonal energy consumption, we determine the system size that best aligns with your business goals.

02

Structural Engineering

Our engineering team evaluates roof structures, foundations, carports, and other mounting locations to ensure the system is designed for long-term safety, durability, and code compliance.

03

Electrical Engineering

We develop complete AC and DC electrical designs, optimize conductor sizing, coordinate utility interconnection requirements, and prepare engineering plans for permitting and construction.

04

Permitting & Utility Coordination

Our team manages the permitting process and works directly with local jurisdictions and utility providers to obtain the approvals required to move your project into construction.

SYSTEM DESIGN

With a year’s worth of electric bills, we determined the size of the system.  We access and evaluate every aspect of the design before beginning.

STRUCTURAL ENGINEERING

We verify roof adequacy assessments, foundation design and carport design.  We look at the building and use our proprietary design software to come up with the absolute best solution, customized for each client.

ELECTRICAL ENGINEERING

Comprehensive DC and AC electrical system engineering, conductor optimization, and interconnection design is performed, and plans are drawn and signed.

PERMITTING

As part of our services, we obtain all permits and necessary approvals from all agencieshaving jurisdiction over your property.

Designed Around Your Business

No two commercial facilities use electricity the same way.

Instead of designing every project to maximize annual energy production alone, CitiGreen designs systems around how your business actually consumes electricity. Factors such as operating hours, utility rate schedules, seasonal demand, future expansion plans, and available installation space all influence the final design.

The result is a system engineered to support your long-term operational and financial goals.

Engineering for Long-Term Performance

Every design is developed with the entire life of the system in mind.

Our engineering process considers:

Historical energy usage and future growth
Utility rate structures and demand charges
Equipment performance and long-term reliability
System accessibility for maintenance
Utility interconnection requirements
Safety and code compliance
Future battery storage integration, when appropriate

Careful planning during the design phase helps reduce construction challenges and supports reliable system performance for decades.

Maximizing the Value of Every Installed Kilowatt

Installing solar is only part of the equation. The real value comes from designing a system that performs efficiently over its entire operating life.

Our design approach focuses on:

Financial Performance:
Projects are evaluated to maximize long-term energy savings and overall return on investment.

Optimized Energy Production:
Equipment selection, system layout, and electrical design are carefully coordinated to maximize performance while minimizing losses caused by shading and other site conditions.

Utility Rate Optimization:
Systems are designed around your utility's billing structure to help reduce electricity costs and demand charges whenever possible.

Performance Monitoring:
Integrated monitoring tools provide ongoing visibility into system production and overall performance, helping identify issues quickly and protect your investment.

Long-Term Support:
Our commitment continues after installation through ongoing system support and operational guidance to help your system perform as intended for years to come.

Engineering Experience That Matters

For more than 24 years, CitiGreen has designed commercial solar projects for businesses throughout Northern California. Our experience spans manufacturing facilities, agricultural operations, schools, municipalities, office buildings, retail centers, warehouses, and other commercial properties.

Every project reflects the same philosophy: thoughtful engineering, careful planning, and practical solutions that create long-term value.

“After searching for the right solar provider, we knew CitiGreen was the right choice. They went above and beyond to help our family business move forward with a financing solution that made the project possible.”
