Faster Utility Approvals. Smoother PTO. Zero Guesswork.
The final hurdle between a completed solar installation and an energized system isn't technical—it's bureaucratic. Utility interconnection and Permission to Operate (PTO) approvals are where most solar projects slow down, stall, or fail—not because of installation quality, but because of utility complexity, documentation gaps, and misaligned requirements.
At Solartro, we eliminate that bottleneck entirely. We manage your complete interconnection and PTO process—from initial utility research through final grid activation—acting as your single point of contact with utilities nationwide.
Stop navigating utility complexity alone. Let us handle the paperwork while you focus on selling and installing exceptional solar systems.
Interconnection is the process of connecting your solar energy system to the local electrical grid. This connection enables the system to supply power to the property and export any excess energy back to the grid for net metering credit.
PTO is the final authorization from the utility company allowing your solar system to operate and feed electricity into the grid. It confirms that your installation meets all safety standards, grid reliability requirements, and regulatory compliance.
Without PTO, the system cannot legally energize—even if installation is 100% complete.
Each step has specific requirements, forms, technical specifications, and approval criteria—and each utility has different processes.
This is where most projects get stuck. Solartro ensures every step moves forward efficiently.
We manage the complete end-to-end interconnection process—from utility research through final PTO—so you never have to chase utilities, resubmit applications, or wonder about approval status.
We identify your exact serving utility, determine the correct interconnection pathway (fast-track vs. standard review), verify net metering eligibility, identify capacity constraints, and document every utility-specific requirement before submission.
Submitting applications without understanding utility-specific requirements is like building without blueprints—you're guaranteed to hit problems. Our research ensures you're prepared from day one.
We prepare complete, utility-ready interconnection packages including accurate single-line diagrams, equipment specifications, protection and metering details, system sizing calculations, and all required forms—aligned with utility engineering standards.
Well-prepared applications get approved. Incomplete applications get rejected—triggering 2–4 week resubmission cycles that delay projects and frustrate customers.
We submit your interconnection application through the correct utility channels (online portals, email), track submission confirmation, monitor application status, and provide regular updates throughout the review process.
Knowing where your application stands—and proactively addressing any issues—prevents projects from falling into “black holes” where weeks pass without progress.
We serve as your single point of contact with utilities, responding to technical questions, coordinating revisions with your design team, supporting engineering reviews, managing utility comments, and handling any resubmissions needed.
Utilities often have questions or request clarifications during engineering review. Quick, accurate responses keep projects moving—slow communication creates bottlenecks that add weeks to timelines.
We coordinate final inspections with utilities (when required), ensure all AHJ inspections are completed and documented, submit final compliance documentation, and verify all prerequisites for PTO approval are met.
Many projects stall at the final stage due to incomplete inspection documentation or unclear final approval procedures. We ensure nothing falls through the cracks.
We submit final PTO application packages, follow up on PTO status with utilities, obtain final utility authorization, coordinate meter activation, and confirm the system is authorized to energize.
PTO is the finish line—but many installers wait weeks wondering when approval will come. We actively manage the process and push for timely approvals.
