The solar cell on a sight isn't typically the primary power source; it's a brilliant backup and manager. It's usually a small, strip-shaped photovoltaic cell mounted on top of the sight body.
Here’s the smart part: In daylight conditions, the solar cell automatically takes over, powering the LED that creates the reticle (the red dot) and preserving your battery. Many advanced models, like those from industry leaders, also feature automatic brightness adjustment. The solar cell senses the ambient light and intuitively adjusts the dot's intensity to ensure it's perfectly visible against your backdrop—never too dim in bright sunlight and never too blinding in low light. This means you get incredible battery life (often tens of thousands of hours) and a dot that's always optimized for the environment.
