Construction Company Timelines and Key Steps for Solar Projects

When prospective clients hear that solar systems in Rhode Island often pay for themselves within five years—or that a well maintained system can deliver a nearly tenfold return on investment over its 30+ year lifetime—the next question is often, “but… what’s the catch?”

The answer? While solar construction projects are a smart financial investment, the most challenging aspect is often the timeline. Most commercial solar projects take between 7-12 months to complete. At CommercialSolarGuy, our expertise as a trusted construction company ensures that every phase of your project is handled with precision and care. Let’s take a closer look at the steps involved:

Step 1: Feasibility and Interconnection (6 months average)

The process begins with developing a site plan and a single-line drawing, which are submitted as part of the utility interconnection request. This step ensures the project complies with utility requirements and lays the foundation for connecting the system to the grid.

Depending on the project’s complexity and the utility’s processing times, this step can take anywhere from 35 days to 22 months. Do you have questions about your project’s feasibility or timeline? Let’s map it out together—click below to connect with our team.

We mitigate delays by focusing on properties with strong hosting capacity to streamline utility approvals, and by proactively using utility data to identify viable interconnection locations early in the process.

Step 2: Permitting and Design (1-3 months)

Once interconnection is underway, the focus shifts to permitting and design. This critical step ensures your project complies with all local regulations and structural requirements. It involves:

  • Structural drawings and engineering calculations.
  • Roof load capacity analysis to confirm your building can support the solar installation.

Permitting fees typically account for 2%-3% of the total project cost. Upon approval, a Notice to Proceed (NTP) is issued, signaling the start of construction.

Hybrid systems, such as solar-plus-storage facilities, are becoming increasingly vital as the U.S. power grid evolves to integrate more renewable energy. These systems allow you to maximize interconnection capacity by delivering power reliably, day and night, while stabilizing energy output and mitigating curtailment. A perfect example of this is the Tioga Downs solar-plus-storage facility in New York, where battery storage enhances energy delivery and ensures consistent performance, even as grid demands and technologies evolve.

Step 3: Procurement and Mobilization (4-6 weeks)

High-quality materials—including inverters, wiring, racking, and solar panels—are sourced during this phase. Delivery timelines may fluctuate due to global supply chain conditions, but typically take 4-6 weeks.

Once materials arrive, our team organizes resources, personnel, and equipment, ensuring the project is ready to move into construction. This mobilization period typically lasts 1-2 weeks.

Step 4: Construction and Commissioning (1-2 months)

With everything in place, construction begins. Depending on the scope of the project, most commercial solar installations are completed within 1-2 months. After construction, we work with local inspectors to:

  • Perform final inspections.
  • Ensure compliance with all regulations.
  • Commission the system, allowing it to begin producing power.

Step 5: Operations and Maintenance (30+ years)

Solar power systems are designed to last decades, but regular care is essential to maximize their performance. Using insights from the U.S. Department of Energy’s free operations and maintenance cost modeling tool, our local crew ensures your system will stay in top shape for years to come.

By partnering with CommercialSolarGuy, you’re not just hiring a construction company—you’re investing in a team committed to efficient timelines, proactive problem-solving, and long-term value for your business.
