- Answer questions about your property
Step 2: On-Site Assessment (1 week)
- Structural evaluation of roof
- Shading analysis and sun exposure
- Electrical system review
- System design based on your needs
Step 3: Quote and Contract (1-2 weeks)
- Receive detailed system proposal
- Review financing options
- Sign installation agreement
- Finalize timeline
Permitting and Preparation
Required Permits
- Electrical permits
- Building permits
- Utility interconnection approval
- Local inspection scheduling
Typical Timeline: 2-6 weeks
The timeline varies by location. Expect longer processing in areas with high solar adoption.

Common Questions
Will my power go out during installation?
Your system is isolated from the grid during installation. Power outages are rare unless required for electrical work.
What about roof damage?
Professional installers use industry-standard practices to protect your roof. Proper flashing and weatherproofing ensure no leaks.
Can I do this myself?
While possible, solar installation requires electrical expertise and permits. Professional installation is recommended for safety and warranty protection.
Conclusion
Understanding the installation process helps you prepare and maintain realistic expectations. From assessment to activation, the journey to solar energy typically takes 2-4 months. Once installed, your system will provide clean energy for 25-30 years.
