Here's why they stop working:
* No Sunlight, No Power: The photovoltaic effect relies on photons from sunlight hitting the solar panel's silicon cells. Without sunlight, there are no photons to trigger the electron flow that produces electricity.
* Nighttime: When the sun sets, the Earth's rotation blocks sunlight from reaching the solar panels.
What Happens During Nighttime:
* No Electricity Production: The solar panels completely stop generating electricity.
* Battery Backup (If You Have One): If you have a battery connected to your solar system, it can provide power for your home during the night. The battery is charged by the solar panels during the day.
* Grid Connection (If You Have One): If you're connected to the electrical grid, your home will draw power from the grid when your solar panels aren't generating.
In short, solar panels are passive devices that only work when sunlight is available. They don't store electricity themselves, so you need a battery or grid connection to use the power generated during the day at night.
