HOW DO SOLAR PANELS WORK?

Solar panels operate on a foundational principle of physics known as the photovoltaic effect. When sunlight strikes the photovoltaic cells in solar panels, it excites electrons within the material, generating an electric current. This critical process allows solar energy to be converted into usable electricity. Most commonly, monocrystalline or polycrystalline silicon-based cells are used due to their effectiveness in capturing sunlight.

To begin with, sunlight penetrates the solar panel, and as photons hit the surface, they induce a flow of electrons. This flow is harnessed through electrical circuits integrated within the panel, ultimately producing direct current (DC). The generated DC electricity is then converted to alternating current (AC) by an inverter, making it suitable for residential or commercial usage.

Moreover, various components work together to optimize the efficiency of solar panel systems. For instance, tracking systems can adjust the angle of panels to follow the sun’s path, maximizing exposure to sunlight throughout the day. Additionally, advancements in technology continuously improve the efficiency of solar panels, allowing for greater electricity generation even with smaller installations.

WHAT FACTORS INFLUENCE SOLAR ENERGY ADOPTION?
