Pepco Solar Approval Process: Step-by-Step Guide
Going solar in Washington, D.C. is an incredible way to lower your electric bill, build long-term energy resilience, and generate valuable Solar Renewable Energy Credits (SRECs). But before your system can start producing clean power, it must pass the Pepco approval process.
At City Renewables, we handle every step for you—from engineering to paperwork to final Pepco Permission to Operate (PTO). Here is a clear breakdown of how the process works.
1. Site Assessment & System Design
Every project starts with a detailed assessment of your roof, electrical system, and energy needs. Our team creates a custom solar design tailored to your home, maximizing production and long-term savings.
What we handle:
- Roof measurements & shading analysis
- Custom engineering plan set
- Load calculations for existing electrical equipment
2. Pepco Interconnection Application (ICA)
Before installation can begin, Pepco requires an Interconnection Application. This ensures your solar system can safely send energy back to the grid.
City Renewables submits on your behalf:
- Pepco ICA form
- Engineering drawings
- Equipment specifications
- Insurance documentation (when required)
Pepco reviews the application and either approves, requests revisions, or asks for a supplemental study for larger systems.
3. Permitting With D.C. Authorities
Once Pepco gives the green light, we submit all required permits, including:
- DCRA building permit
- Electrical permit
- Historic district approvals (if applicable)
Our team manages the entire permitting process so you never have to deal with city paperwork.
4. Solar Installation
After permits are approved, our certified installation team completes your solar project safely and efficiently—usually in just 1–2 days for standard residential systems.
What the installation includes:
- Mounting hardware & racking
- Solar panels
- Inverters or microinverters
- System wiring & electrical upgrades (if needed)
5. Inspections (DCRA & Pepco)
Your system must pass inspections before Pepco will allow it to operate.
DCRA Final Inspection
A city inspector ensures the system is built according to the approved plans and meets all electrical and safety standards.
Pepco Meter Installation or Upgrade
Pepco may install a new bi-directional meter that measures both:
- Energy you use
- Energy you send to the grid
6. Permission to Operate (PTO)
Once all inspections are passed and your meter is updated, Pepco issues Permission to Operate. This is the official approval that allows your solar system to start generating and exporting electricity.
At this point—you’re officially a solar producer!
7. Ongoing Monitoring & Support
City Renewables provides full access to your monitoring portal, so you can track solar production and performance in real time. We also remain available for support, maintenance, and system optimization.
