If your organization decides to adopt solar power, you will soon embark on two critical business partnerships. The first will be with Solar by EnFin, responsible for designing the photovoltaic (PV) solar system. The second partnership will be with the local utility. Once your solar panels are connected to the grid, you’ll establish a more lucrative relationship with the local utility company than ever before.

Project Management

Solar by EnFin comprehensively understands the intricacies of solar systems and is highly knowledgeable about what utilities demand during the installation process. Following the contract signing, the day-to-day communication with the utility will be primarily handled by two key individuals. The first is the project manager, who will supervise the entire construction phase of the solar project from start to finish. This project manager will closely collaborate with the interconnection coordinator, tasked with overseeing the technical aspects of aligning the solar system with the utility’s equipment.

The Process

Utilities vary from region to region, each with its own set of rules regarding connecting solar panels to the grid. It’s the responsibility of the project manager and interconnection coordinator to comprehend these regulations and ensure the project remains on course. The process entails five major steps from start to finish before the solar system is operational.

1. Site Survey: The project begins with a series of surveys examining everything from the utility’s underground cables to your own switchgear, which includes breakers and fuses safeguarding your equipment. Additionally, factors such as the area’s topography and any elements impacting solar production are taken into consideration. This aids in determining the optimal location for the solar system.
2. Design: Utilizing this data, a “30 percent design” is crafted, indicating that the design is roughly 30% complete. This plan primarily comprises two drawings—a single line drawing illustrating the electrical diagram and a site plan showing the placement of the solar array(s). These drawings, submitted as an “Interconnection Application” to the utility, seek permission to proceed with construction.
3. Permits: While awaiting approval from the utility, the project manager finalizes the design and obtains any necessary permits, which may include building, city, and state permits. This process’s duration varies based on location and the complexity of the solar design. Additionally, the utility may require adjustments to the wiring, meter, or other equipment to ensure compatibility. Larger projects might necessitate additional grid integration studies.
4. Construction: Upon receiving approval from the utility and commencing construction, the project manager assumes primary responsibility. They oversee the delivery, installation, and connection of panels and other hardware, ensuring a smooth process. Subsequently, government inspectors—typically from the city or state—review the installation to ensure compliance with all requirements. The project manager handles inspections and addresses any necessary adjustments.
5. Operation: Following inspection, the project manager requests permission to operate (referred to as a “PTO”) from the utility, which conducts a final assessment. With their approval, you can activate the system and begin generating solar power. However, the project manager remains involved for a few weeks afterward to ensure proper system monitoring and address any concerns.

The typical commercial solar installation process spans about 10 months to a year, though more complex projects may take longer. Post-installation, your relationship with the solar company will likely endure throughout the equipment’s lifespan. Meanwhile, your connection with the utility shifts to that of a fellow electricity generator. In most cases, net metering helps offset your energy costs, resulting in lower energy bills and environmental benefits.
