How Do Solar Panels Work? Solar Power Explained
You probably already know that solar panels use the sun''s energy to generate clean, usable electricity. But have you ever wondered how they do it? At a high level, solar panels are made up of solar cells, which absorb sunlight. They use this sunlight to create direct current (DC) electricity through a process called "the photovoltaic effect."

Towards improved cover glasses for photovoltaic devices
Typical dimensions of a domestic PV module are 1.4–1.7 m 2, with >90% covered by soda–lime–silica (SLS) float glass. 9 The glass alone weighs ~20–25 kg since the density of SLS glass is ~2520 kg/m 3. This presents engineering challenges as current solar panels are rigid and need strong, heavy support structures.
Why Is Silicon Used In Solar Panel Manufacturing?
PV modules using crystalline silicon solar cells have a long outdoor life (>20 years).
