EPC stands for Engineering, Procurement, and Construction. It is the industry standard delivery model for commercial solar projects. When you hire an EPC contractor, you get a single company responsible for every phase of your project, from initial design through final commissioning. No finger-pointing between separate contractors. No gaps in accountability.
The foundation of every commercial solar project. Engineering includes site assessment, structural analysis, electrical design, energy modeling, and permit-ready construction documents.
Sourcing and purchasing all equipment, materials, and components. An EPC contractor leverages volume pricing and manufacturer relationships that individual building owners cannot access.
Physical installation, electrical work, inspections, and utility interconnection. This is where the design becomes a working power plant on your roof, carport, or ground-mount structure.
When you are investing $200,000 to $2 million in a commercial solar system, who builds it matters as much as what gets built. The EPC model exists because commercial solar is too complex and too expensive to leave to disconnected contractors working off separate scopes.
If panels underperform, the racking fails, or the electrical system trips, you call one company. There is no debate about whose fault it is. The EPC contractor designed it, bought it, and built it. They own the outcome.
When the same team that designs the system also builds it, the design is practical. You avoid the disconnect that happens when a design firm creates plans that a separate installer has to figure out in the field, leading to change orders and delays.
With an EPC contractor, your workmanship warranty comes from one entity. There is no gray area between the design firm, equipment supplier, and installer about who covers what. One warranty, one company, one phone number.
EPC contractors deliver fixed-price proposals with defined timelines. You know the total cost before signing. Compare that to managing multiple contractors where costs creep and schedules slip because no one owns the full scope.
There are three ways to get a commercial solar system installed. Each approach has different implications for cost, risk, and accountability.

Why Keen Energy
Keen Energy is not a sales organization that subcontracts your project. We are a licensed C-10 Electrical Contractor with in-house engineering, procurement, and construction capabilities. Our founding team has deployed over 800 megawatts of commercial solar across California. That experience shows in every project we deliver.
We hold a California C-10 Electrical Contractor license. Our in-house electrical crews include state-certified Journeymen and Apprentices. We do not subcontract our electrical work, which gives us direct control over safety, quality, and schedule.
We are a Western Electrical Contractors Association (WECA) member and fully compliant with California's prevailing wage requirements, including AB 2143. Our compliance is built into our operations, not bolted on after the fact.
We manage utility interconnection across SCE, SDG&E, LADWP, IID, and municipal utilities throughout California. Each utility has different requirements, timelines, and forms. We know them because we work with them regularly.
Whether you want to purchase outright, finance through a loan, or go with a Power Purchase Agreement (PPA) that requires zero upfront cost, we work with PPA providers and financing partners to match the right structure to your goals.
Here is what a commercial solar project looks like when you work with an EPC contractor. Every step is managed by Keen Energy, so you have one point of contact from the first phone call through final commissioning.
We visit your property, evaluate the roof or ground area, review your utility bills and rate schedule, and identify the system configuration that delivers the best financial return. This assessment is free and includes a preliminary production estimate and ROI analysis.
Our engineering team creates detailed construction documents including structural calculations, electrical single-line diagrams, panel layout, and equipment specifications. These documents are submitted for permitting and used to guide construction. Because we also build what we design, our plans are practical and buildable.
We source and purchase all equipment: Tier-1 solar panels, inverters, racking, electrical components, and battery storage if applicable. Our procurement team manages logistics to ensure materials arrive on schedule and meet FEOC compliance requirements for the federal tax credit.
We handle all permit applications with the local building department and submit the utility interconnection application. This step runs in parallel with procurement to keep the schedule on track. We manage all revisions and plan check responses.
Our in-house crews handle the physical installation: mounting the racking system, placing and wiring the panels, installing inverters, running conduit and wiring, and integrating battery storage if included. Our C-10 licensed electricians handle all electrical work in-house.
After passing all inspections, we coordinate the utility meter installation and final interconnection. The system is tested, commissioned, and handed over to you with monitoring configured and all documentation complete. Your system starts generating electricity and savings.
Own the building, own the decision. Direct purchase or PPA, an EPC contractor gives you a single contract for the entire project.
Responsible for building operations and energy costs. An EPC simplifies the process so you manage one relationship, not five.
Real estate and solar developers need reliable EPC partners who deliver on schedule and on budget. Our track record speaks for itself.
Managing multiple properties with solar potential? We work with property management firms to evaluate and execute solar across portfolios.
