Planning the Installation
Begin by mapping the roof and existing electrical layout. Identify the optimal panel orientation for maximum sun exposure while ensuring the Arlo Pro cameras remain within the 120‑foot line of sight. Use a solar calculator to estimate the system size needed to offset your electricity bill, then confirm that the existing 240‑V service panel can accommodate the additional load.

Choosing the Right Equipment
Select panels with a high power‑to‑area ratio to fit the roof space. Opt for micro‑inverters or a string inverter that offers a low output voltage, reducing the risk of back‑feeding into the home's circuits. For the Arlo Pro, ensure the battery backup or solar‑powered charger is rated for the same voltage and has a built‑in surge protector.
Protecting the Arlo Pro Wiring
Run the Arlo Pro power line in a conduit that is insulated from the solar panel wiring. Install a dedicated breaker for the camera system to isolate it from the solar array's load. Add a 30‑A GFCI breaker to safeguard against accidental short circuits during maintenance.
Installing the Solar Array
Mount the panels on a racking system that aligns with the roof's pitch. Connect the panels to the inverter using weather‑sealed junction boxes. From the inverter, run a 240‑V feed to the main panel, and then to a sub‑panel dedicated to the security system. This keeps the Arlo Pro's power separate from the main household load.
Integrating with the Arlo Pro System
Configure the Arlo Pro to draw power from the new sub‑panel. If you wish to power the cameras with solar, install a small solar‑to‑battery charger that feeds a 12‑V battery bank. The Arlo Pro's built‑in battery can be recharged through the charger, ensuring continuous operation during power outages.
Testing and Verification
After installation, test the system with a load test on the sub‑panel. Verify that the Arlo Pro cameras maintain signal integrity and that the inverter's output remains stable. Perform a short‑circuit test on the camera wiring to confirm GFCI protection.
Maintenance Tips
Schedule quarterly inspections of the solar panels to remove debris that could reduce efficiency. Check the Arlo Pro's firmware and battery health monthly. Document any changes in the electrical schematics to aid future upgrades.
Common Pitfalls and How to Avoid Them
1. Overloading the Main Panel: Adding solar without upgrading the main panel can trip breakers. Upgrade to a 200‑A service if necessary.2. Neglecting Grounding: Both solar and security systems must share a common grounding point to prevent voltage spikes.3. Ignoring Local Codes: Verify that the installation meets NEC and local HOA regulations.
