How Solar Power and Energy Storage Work — A Quick Technical Overview
Solar energy is one of the most popular green energy sources today, widely used in residential, commercial, and industrial settings. This article explains how solar power systems generate and store electricity, using easy-to-read tables and short summaries.
Core Principle of Solar Power: The Photovoltaic Effect
When sunlight hits a solar panel, it triggers a process known as the Photovoltaic Effect, which converts light energy into electricity.
|
Step |
Description |
|
Photon Absorption |
Photons from sunlight are absorbed by the solar panel (typically made of silicon). |
|
Electron Excitation |
The energy from the photons excites electrons in the silicon atoms, releasing free electrons. |
|
Current Generation |
The movement of these free electrons through a circuit generates direct current (DC). |
|
Power Conversion |
An inverter converts DC into alternating current (AC), suitable for home or business use. |
Why
Silicon?
Silicon is widely used because it’s abundant, stable, and has excellent light
absorption and conductivity properties.
Role of Energy Storage Systems
Since solar energy is intermittent, it must be stored for use at night or during cloudy days. This is where energy storage batteries come into play.
|
Storage Phase |
Function |
|
Charging |
Excess electricity is stored in lithium batteries or other storage units. |
|
Discharging |
Power is released from the batteries when there’s no sunlight, supplying homes or equipment. |
Battery
Comparison
Lithium batteries are the mainstream choice for their high energy density and
long lifespan, while traditional lead-acid batteries are cheaper but heavier
and shorter-lived.
