Solar Panel Size Calculator
Size the right solar panel for your 2K, 4K, or higher-res security camera. Tuned for Arizona sun, dust, and heat — with a built-in safety margin.
Turn on for devices that don’t have IR LEDs (power is constant).

Why the extra headroom? Arizona has great sun, but dust buildup, panel heat (high temps drop output ~10-15%), shading, and wiring losses are real. We divide by 0.80 to bake in a 20% safety margin so your camera doesn’t die on a cloudy morning.
Sizing tip: Use the worst-month number if the camera needs to run through December. Use the average-year number if it’s seasonal (e.g., job-site from April to October).
