EPC solar refers to solar projects delivered under an Engineering, Procurement, and Construction (EPC) model. A solar EPC contractor is responsible for detailed engineering, equipment procurement, and full construction and commissioning, providing a single point of accountability for schedule, budget, and performance.

What does a solar EPC contractor do?

A solar EPC contractor manages the end-to-end delivery of a solar project, including site assessment, system design, structural and electrical engineering, equipment selection and purchasing, construction management, commissioning, and handover to operations and maintenance. Many EPCs also support performance monitoring and long-term service.

What types of projects are suited for EPC solar?

EPC solar is commonly used for commercial, industrial, agricultural, and utility-scale projects. Rooftop solar, large ground-mounted arrays, solar carports, and solar-plus-storage microgrids often benefit from an EPC delivery model because it streamlines schedule, risk management, and quality control.

Where do you provide EPC solar services?

We provide EPC solar services for commercial, industrial, agricultural, and utility-scale projects across Washington, Montana, and Oregon, with a deep understanding of regional utilities, permitting requirements, and incentive structures.

What Is EPC Solar?

EPC solar refers to solar projects delivered under an Engineering, Procurement, and Construction model. In an EPC contract, a single partner is responsible for the full technical design, equipment sourcing, and construction of your solar project, providing a turnkey solution from early development support through commissioning.

For commercial, industrial, agricultural, and utility-scale solar, the EPC model simplifies coordination, reduces interface risk between multiple vendors, and ensures that all design and construction decisions are aligned with long-term performance, safety, and financial goals.

Why EPC?

Why EPC Solar Matters for Complex Projects

As system sizes grow and interconnection requirements become more demanding, an experienced solar EPC contractor becomes essential to delivering bankable, grid-compliant assets.

1. Single-Source Responsibility

With EPC solar, one partner owns the engineering, procurement, and construction scope. That means fewer handoffs, less finger-pointing, and clear accountability for cost, schedule, and performance.

2. Optimized System Design

EPC engineers design for constructability, long-term reliability, and O&M efficiency. Every decision — from racking layout to combiner configuration — is made with lifecycle performance in mind.

3. Procurement Power & Quality Control

An experienced EPC solar contractor leverages vetted supplier networks and volume pricing, ensuring equipment is bankable, compatible, and delivered on schedule with proper quality documentation.

4. Construction Management & Safety

EPC solar projects involve complex civil, structural, and electrical work. We manage crews, logistics, safety plans, and QA/QC requirements to keep your site productive and compliant.

5. Bankability & Performance Assurance

Investors, lenders, and off-takers prefer EPC solar contracts because they centralize responsibility. Detailed as-built documentation, test reports, and performance guarantees support financing and long-term asset management.

Process

Our EPC Solar Delivery Process

A disciplined EPC approach keeps stakeholders aligned and projects moving. Here’s how we deliver EPC solar projects from initial concept to energized asset.

1. Feasibility & Early Development Support

We begin with a detailed feasibility review that includes site conditions, load analysis, interconnection options, and high-level production modeling. For developers and owners, we can also assist with RFP responses and early-stage project structuring.

2. Detailed Engineering & Interconnection

We develop full construction drawings, protection schemes, and interconnection packages that align with utility standards. This includes structural calculations, electrical studies, and stakeholder reviews to ensure the design is ready for permitting and financing.

3. Procurement & Logistics

Once the design is locked, we secure all major equipment and materials, sequence deliveries to match the construction schedule, and manage logistics to prevent bottlenecks. Our team coordinates closely with suppliers to maintain quality and traceability.

4. Construction & Commissioning

We oversee on-site crews, safety, and quality control during construction. After mechanical and electrical completion, we perform testing, energization, and performance verification to ensure the system meets or exceeds design expectations and interconnection requirements.

5. Handover, Monitoring & O&M Coordination

At project closeout, we provide as-built drawings, test reports, warranty documentation, and O&M manuals. We also support monitoring configuration and can coordinate ongoing maintenance to protect long-term asset performance.

FAQ

EPC Solar FAQ

Answers to common questions about EPC solar contracts, delivery timelines, and where EPC fits in the solar
project lifecycle.

What is EPC solar?

EPC solar is a delivery model in which a single contractor is responsible for the engineering, procurement, and construction of a solar project. The EPC partner designs the system, sources equipment, builds the project, and delivers a fully commissioned asset ready for operation.

What does a solar EPC contractor handle?

A solar EPC contractor handles technical design, permitting support, full equipment procurement, site construction, commissioning, and project turnover. Many EPC firms also coordinate with lenders, utilities, and long-term O&M providers on behalf of the owner or developer.

Which projects benefit most from EPC solar?

Larger and more complex projects—such as commercial and industrial rooftops, multi-MW ground-mounts, solar carports, microgrids, and utility-scale plants—benefit significantly from an EPC delivery model, where centralized responsibility and coordination reduce risk.

How long does an EPC solar project take?

EPC solar timelines vary by size and complexity. Smaller commercial projects may complete in 6–9 months, while multi-megawatt or utility-scale projects can take 12–18 months or longer due to interconnection studies, permitting, and construction scope.
