Properties that use solar panels tap into an off-the-grid, environmentally friendly source of electricity — the sun. Solar energy also provides lower utility costs, making it beneficial to both the planet and its people. How do solar panels work? Sun King in Kahului, HI, explains.
Solar panels harness sunlight and convert it into electricity to power homes and businesses. Particles of light, or photons, push electrons free from atoms and generate electricity. Solar panels are typically made up of many small photovoltaic cells, which convert sunlight into usable electricity. The cell consists of two layers of a semiconductor material, usually silicon.
To make the cells work, an electric field must occur. The bottom half of the cell is infused with boron for a positive charge while the top layer has phosphorous for a negative charge, creating the field. When sunlight moves an electron free, the electric field pushes the electron out of the area where the layers of the cell meet, called the junction. The panels then turn the electrons into power, with conductive metal plates collecting the electrons and moving them into wiring, letting the electric current flow.
Groups of photovoltaic cells make up solar panels that can be used separately or together in larger arrays. Different types of cells use varying levels of materials and energy to convert sunlight into electricity, such as single-crystal cells that use more materials but produce the highest efficiency. Polycrystalline cells make up about half the market and have lower production costs, but also have lower cell efficiency.
