Making the switch to solar is a smart move—for your wallet, your energy independence, and the environment. But if you're new to the process, you might be wondering: What actually happens during a solar panel installation?
Before anything is installed, a solar professional will visit your property to:
Inspect your roof’s size, angle, and shading
Evaluate your home’s electrical system
Discuss your energy usage and goals
Recommend the best type and number of panels
Tip: Have your utility bills ready for this meeting. It helps determine the right system size.
Once the site assessment is done:
A custom solar system design is created
The installer submits permit applications to local authorities
In some cases, approvals from homeowners’ associations or utility companies are also needed
Timeline: Permitting can take 2–4 weeks, depending on your region.
Once all permits are approved, it’s installation time! Here's what typically happens:
Residential Systems: Usually 1–2 days
Commercial Systems: 3–7 days, depending on size and complexity
Workers will mount racking systems onto your roof or ground
Panels are attached securely
Wiring is connected to the inverter and your electrical panel
If you have a battery, it will also be installed
Good to Know: Most systems don’t require major electrical changes or roof modifications.
After installation:
The system is inspected by your local building department
Your utility provider reviews the setup and grants PTO (Permission to Operate)
This is a crucial step. You can't activate your system until you get official approval.
Timeline: May take 1–3 weeks after installation.
Once you receive PTO:
Your installer or technician will activate the system
You'll be shown how to monitor energy production via a mobile app or online portal
From here on, your system starts saving you money!
Keep panels clean: Dirt and debris can lower performance
Schedule regular maintenance: A check-up every 1–2 years is ideal
Monitor performance: Catch any dips in output early using your solar app
Site survey scheduled
Design approved & permits submitted
Installation date confirmed
System inspected & approved
System activated and generating power
The solar installation process is smooth, efficient, and minimally disruptive—especially when handled by experienced professionals. From consultation to clean energy production, you’ll be guided every step of the way. So if you're ready to lower your electricity bills and reduce your carbon footprint, now you know exactly what to expect!
