Solar Panels: Unlock Clean Energy & Slash Electricity Bills Today

How Do Solar Panels Work

Solar panels generate electricity through a sophisticated process called the photovoltaic effect. When sunlight strikes the solar cells, photons interact with semiconductor materials (typically silicon) to produce electrical current.

Photovoltaic Cell Mechanism

P.V. cells convert solar energy into electricity using these key steps:

  1. Photon Absorption: Sunlight particles (photons) strike the silicon layers in solar cells
  2. Electron Excitation: Photons knock electrons free from silicon atoms
  3. Electric Field Generation: Doped silicon layers create an internal electric field
  4. Electron Flow: Freed electrons move through a circuit, producing direct current (D.C.) electricity

Energy Conversion Process

Your solar panel system transforms solar energy through multiple stages:

  1. Sunlight Capture: Solar cells absorb incoming photons
  2. D.C. Electricity Generation: Electrons create direct current electricity
  3. Inversion: Inverters convert D.C. to alternating current (A.C.) electricity
  4. Electricity Distribution: A.C. electricity powers home appliances or feeds into the electrical grid
