    How Do Solar Panels Work? A Beginner's Guide to Solar Energy

    From Sunlight to Electricity

    Solar panels might look like magic, but the science behind them is straightforward. Here's how your rooftop panels turn California sunshine into power for your home.

    The Photovoltaic Effect

    Solar panels are made up of photovoltaic (PV) cells — typically made from silicon. When sunlight hits these cells:

  1. Photons (light particles) knock electrons loose from silicon atoms
  2. An electric field in the cell pushes these electrons in one direction
  3. This flow of electrons creates direct current (DC) electricity
  4. From DC to AC: The Inverter

    Your home appliances run on alternating current (AC), but solar panels produce DC. That's where the inverter comes in:

  5. String inverters — One central inverter for the whole system
  6. Microinverters — Individual inverters on each panel (better for shading)
  7. Power optimizers — A hybrid approach combining benefits of both
  8. Net Metering: Your Electric Meter Spins Backward

    When your panels produce more electricity than you use:

  9. Excess power flows back to the utility grid
  10. Your meter tracks the energy credits
  11. You use those credits when panels aren't producing (nighttime, cloudy days)
  12. Battery Storage: Energy Independence

    Adding a battery system lets you:

  13. Store excess solar energy for nighttime use
  14. Keep power during grid outages
  15. Maximize self-consumption of your solar energy
  16. Reduce reliance on utility time-of-use rates
  17. How Much Energy Can You Produce?

    In Bakersfield, we get an average of 271 sunny days per year — one of the highest in the nation. A typical residential system:
