Montgomery County Inspection Requirements
After installation, your solar system must pass multiple inspections before receiving Permission to Operate (PTO) from Pepco and SREC activation:
Electrical Rough-In Inspection
Timing: After wiring, before wall/ceiling closure
Inspector: Montgomery County Electrical Inspector
Focus: Wiring methods, grounding, junction boxes
Code: National Electrical Code (NEC) + Maryland amendments
SREC Check: Production meter wiring verification
Result: Green tag if approved
Final Electrical Inspection
Timing: After full system installation
Inspector: Montgomery County Electrical Inspector
Focus: Complete system safety, labeling, disconnect switches
Critical Check: Rapid shutdown compliance (NEC 690.12)
SREC Verification: Production meter accuracy test
Result: Final approval for electrical work
Pepco Interconnection Inspection
Timing: After County electrical approval
Reviewer: Pepco Solar Program Specialist
Focus: Net metering equipment, production meter, SREC meter
Requirement: Must use Pepco-approved bi-directional meter
SREC Activation: Meter data feed established for PJM-GATS
Result: Permission to Operate (PTO) letter from Pepco
Germantown Inspection Tip:
Schedule your County electrical inspection through the Montgomery County DPS Online Portal. Most inspections can be scheduled within 3-5 business days. Your solar installer typically handles all inspection scheduling and coordination, including SREC meter verification.
Pepco Connection & SREC Registration Process
Pepco has specific requirements for connecting your solar system to the grid, and Maryland requires SREC registration. Following their processes ensures smooth net metering and SREC income:
Interconnection Application
Form: Pepco Net Metering Application
Timing: Submit with permit application
Requirements: System specifications, single-line diagram, SREC meter details
Fee: $100 application fee
Approval Time: 15-20 business days
SREC Note: Application includes PJM-GATS generator registration
Equipment Requirements
Meter: Pepco provides bi-directional net meter
Production Meter: Required for SREC tracking (installed by solar company)
Inverter: Must be UL 1741 SA compliant
Disconnect: Visible, accessible AC disconnect required
Labeling: Specific warning labels per Pepco standards
Monitoring: Production data accessible for SREC verification
SREC Registration & Income
Program: Maryland Solar Renewable Energy Credit (SREC)
Registration: PJM-GATS account setup required
Income: $500-$900 annually for Germantown systems
Payment: 1 SREC = 1,000 kWh = $50-$90 payment
Broker: SRECTrade, Flett Exchange, or other SREC aggregator
Timeline: First SREC payment 2-3 months after activation

Germantown-Specific Solar Considerations
Germantown's location in Montgomery County presents unique factors for solar installations:
Tree Coverage & Shading
Challenge: Many Germantown neighborhoods have mature trees
Solution: Professional shading analysis using solar pathfinder
Option: Tree trimming permits available through Montgomery County
Technology: Microinverters recommended for shaded areas
SREC Impact: Shading reduces SREC production - important to factor
Homeowner Association (HOA) Considerations
Prevalence: Many Germantown communities have HOAs
Maryland Law: HOAs cannot unreasonably restrict solar
Common Requirements: Rear roof placement, aesthetic guidelines
Process: HOA architectural review typically 2-3 weeks
Pro Tip: Submit HOA application concurrent with County permitting
Climate Considerations
Snow Load: Systems designed for Maryland snow accumulation
Temperature Range: Equipment rated for Maryland's climate extremes
Production: 4.2 peak sun hours daily average in Germantown
Seasonal Variation: Higher production spring-fall, lower in winter
SREC Seasonality: Most SRECs generated April-September
