How Photo voltaic Panels Work

Photo voltaic panels are an effective way to harness the earth’s pure assets to energy our man-made equipment. You should utilize them to be self-sufficient and begin dwelling off-grid. You’ll have tried a few DIY photo voltaic panel tutorials and even realized the correct method of putting in them, however have you learnt how they work? It’s all the time been one thing I’m interested by so when I discovered this infographic, I knew it was one thing I needed to share. So scroll on and see how photo voltaic panels work with this beneficial animated infographic.

Anatomy of a Photo voltaic Cell

Solar Cell

  • Protecting glass
  • Silicon (N-type)
  • Conductive metallic base
  • Conductive metallic contact
  • Silicon (P-type)

Why Silicon?


Silicon is a semi-conductor. It may both conduct electrons or insulate them, relying on the scenario.

  • Silicon atoms have 4 outer electrons that kind a steady crystal construction when bonded.
  • Mixing silicon with parts which have a special variety of electrons creates an unbalanced construction.
  • Boron has three outer electrons. When combined with silicon, it creates a gap within the construction.
  • The holes are cell and carry a optimistic cost, leading to P-type silicon.
  • Phosphorus has 5 outer electrons. Silicon bonds tightly to 4 of these electrons, leaving the fifth to roam free.
  • The free electrons carry a detrimental cost, creating N-type silicon.

The P-N Junction

When P-type and N-type silicon are layered collectively, among the electrons and holes come collectively, forming an electrical discipline.

The electrical discipline repels the free holes and electrons and maintain them from shifting between layers.

Enter Daylight

The vitality from daylight disrupts the bonds in each P-type and N-type silicon, creating free-roaming electrons and holes in each layers.

Free electrons and holes zapped free by daylight are pressured again into their correct later.

Should you join each layers with a circuit, engaging pressure will drive the surplus electrons and holes collectively, creating an electrical present.

What Subsequent?

Photo voltaic cells generate direct present (DC), however most home equipment run on alternating present (AC). DC runs from the photo voltaic cells via an inverter to be used in houses.
