READ MOREThe Basics: How Solar Energy Works. At its essence, the process of harnessing solar energy involves the following key steps: 1. Absorption of Sunlight. Solar panels, also known as photovoltaic (PV) cells, are designed to absorb sunlight. These panels consist of semiconductor materials that have the remarkable ability to convert sunlight into
READ MOREHow Solar Energy Works. Solar energy—power from the sun—is a vast, inexhaustible, and clean resource. Solar electricity generation represents a clean alternative to electricity from fossil fuels, with no air and water pollution, no global warming pollution, no risks of electricity price spikes, and no threats to our public health.
READ MOREHow does home solar power work? Solar power works by converting sunlight into electricity through the photovoltaic (PV) effect. The PV effect is when photons from the sun''s rays knock electrons from their atomic orbit and channel them into an electrical current.
READ MORESolar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of

READ MOREThe first step in reading a solar energy system diagram is to identify the different components of the system. This may include solar panels, inverters, batteries, charge controllers, meters, and other devices. Each component plays a specific role in the overall functioning of the system. 2. Understand the flow of energy.
READ MOREDiagram of a hydroelectric turbine and generator. Credit: U.S. Army Corps of Engineers. As to how this generator works, the Corps of Engineers explains it this way: "A hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity.
READ MOREA wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
READ MOREHow does solar power work? Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to ''solar farms'' stretching over acres of rural land.
