How we deliver your project

One EPC contract. One accountable team.

We hold the EPC contract and run design coordination, procurement, project management, site supervision, safety and QA/QC.

  1. Learn

    We start with your goals, site needs, schedule, and incentive opportunities.

  2. Evaluate

    We assess project feasibility and define the requirements for delivery.

  3. Design, procure, and build

    We keep design, equipment deliveries, and construction aligned.

  4. Commission and energize

    We test the system, coordinate utility approvals, and verify performance before handover.

  5. Hand over and support

    We complete project handover and provide a clear point of contact for warranty support.

How we keep your project on track

    • Establish a baseline schedule with clear project milestones
    • Coordinate design, procurement, and construction through one accountable project manager
    • Use early pricing to guide scope and design decisions
    • Evaluate equipment and subcontractor choices against your budget
    • Order long-lead equipment as soon as specifications are confirmed
    • Track orders and delivery dates against the construction schedule
    • Select crews with the experience, capacity, and local presence your project needs
    • Coordinate crew availability and work sequencing to keep construction moving
    • Keep you informed of progress, upcoming work, and decisions that need attention
    • Document construction progress with aerial updates and closeout records
    • Plan for site risks before mobilization and reinforce expectations through daily briefings
    • Inspect work at defined hold points and track corrective actions through closeout
Bring us in early

Get a budget and a constructability read before design is final

We can join at any stage. The earlier we see the drawings, the more we resolve on paper instead of in the field.

Precon offer

Send us a site plan and single-line diagram

We typically return:

  • Budget price
  • Constructability notes
  • Long-lead equipment list
  • Baseline schedule

We can turn it around in as little as one week. We confirm the timeline once we've reviewed your project information.

Design & development

Engineering and development support to move ground-mounted and rooftop solar projects from early planning toward construction.

Where we work

Map of the United States. Design & development projects across 25 states, highlighted in green: Alabama, Arizona, California, Colorado, Florida, Georgia, Illinois, Indiana, Kansas, Maryland, Michigan, Missouri, Nevada, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, Tennessee, Texas, Utah, Virginia, Washington and West Virginia. All other states are muted.

  • Design & development projects across 25 states

Site planning & permitting

We develop site layouts that help limit earthwork and support zoning and special use permit applications.

Interconnection support

We support interconnection applications and coordinate with ComEd and Ameren. Engineering deliverables are prepared and sealed by licensed Professional Engineers.

Program & incentive guidance

We help your team navigate Illinois Shines and Illinois Solar for All, along with applicable Equity Eligible Contractor requirements, to support your project planning.

Preconstruction planning

We coordinate equipment, tracker, and racking selections around constructability and lead times. We also work with your team to address domestic content and safe harbor requirements in procurement planning.

Our advantage

Engineering with construction in mind.

Bring us your design, or have us develop it as part of your EPC project. We review site conditions, equipment specifications, and installation requirements to identify issues before construction.

Our co-founder, a Professional Engineer licensed in 25 states, works with our in-house technical team on every project. Designs we deliver are prepared and sealed by licensed Professional Engineers.

Rooftop solar, Chicago

  • Early equipment procurement: We ordered the transformer, switchgear, and other long-lead electrical equipment based on the 30% drawings. Equipment lead times of up to 32 weeks ran alongside design development.
  • Site coordination: We identified site obstacles missing from the drawings and led the engineering updates to reflect actual site conditions before they became problems in the field.

Ground-mounted solar, central Illinois

  • Drawing coordination: Before drawings were issued for construction, we identified an electrical layout that did not match the latest tracker drawings.
  • Equipment availability: We identified equipment that couldn’t be supplied as specified and sourced an available alternative.
