Step 1: Consultation & Site Assessment
The solar panel installation process begins with an initial consultation, either in-person or virtual, followed by a detailed site assessment. According to the U.S. Department of Energy, proper site assessment is crucial for optimal system performance.
What Happens During Site Assessment:
- Roof inspection: Condition, age, material, pitch
- Shading analysis: Trees, chimneys, nearby buildings
- Electrical system review: Panel capacity, wiring
- Sunlight analysis: Optimal panel placement
- Structural assessment: Roof load capacity
Time Required
On-site assessment
Plus 30-60 min consultation
Preparation Tips
Have your electricity bills ready for the past 12 months. Clear access to your attic and electrical panel. Be prepared to discuss your energy goals and budget.
Step 2: Design & Proposal Phase
Based on the site assessment, the installer creates a customized system design and detailed proposal for your solar panel installation process. The National Renewable Energy Laboratory (NREL) provides guidelines for optimal system design.
System Design Includes:
- Panel layout and placement
- Inverter type and location
- Wiring diagram
- Mounting system details
- Production estimates
Proposal Includes:
- Total system cost
- Financing options
- Savings projections
- Warranty details
- Installation timeline
Important
Get at least 3 proposals from different installers. Compare not just price, but equipment quality, warranty terms, and installer experience.
Step 3: Permits & Paperwork
This is typically the longest phase of the solar panel installation process. Your installer handles most of the paperwork, but you'll need to provide some information. The Solar Energy Industries Association tracks regulatory requirements across states.
| Document | Purpose | Who Files | Time Required |
|---|---|---|---|
| Building Permit | City/county approval | Installer | 2-4 weeks |
| Electrical Permit | Electrical work approval | Installer | 1-3 weeks |
| Utility Interconnection | Grid connection approval | Installer | 2-6 weeks |
| Incentive Applications | Tax credits & rebates | You (with help) | Varies |
What You Need to Provide:
- Proof of home ownership
- Recent utility bills
- Homeowner's insurance info
- Electrical panel photos
- Mortgage information
- Contact information
Step 4: Equipment Delivery
Once permits are approved, equipment is ordered and delivered to your home. All equipment should arrive in one delivery for the solar panel installation process.
Typical Equipment Delivered:

After installation, several inspections are required before the solar panel installation process can be completed and the system activated.
| Inspection | Who Conducts | What They Check | Timing |
|---|---|---|---|
| Building Inspection | City Inspector | Structural integrity, code compliance | 1-2 weeks after install |
| Electrical Inspection | Electrical Inspector | Wiring, grounding, safety | 1-2 weeks after install |
| Utility Inspection | Utility Company | Meter, interconnection safety | 2-4 weeks after install |
Pass Rate
Pass first inspection
Minor fixes sometimes needed
Important
Do not turn on your system until all inspections are passed and you receive approval from your utility company. Turning it on prematurely can be dangerous and void warranties.
Step 7: Activation & Monitoring
Once all approvals are received, your system is activated and you can start generating solar power! The solar panel installation process is now complete.
Activation Day:
- Utility meter swap: Installation of net meter
- System commissioning: Final testing and activation
- Monitoring setup: App/portal access setup
- Final walkthrough: System operation demo
- Paperwork delivery: Warranty, manuals, permits
