How Solar Power Works

With more and more focus being placed on renewable energy and energy efficiency, it’s no wonder that solar power is becoming so popular. People of all ages are becoming more interested in green energy and its applications, but many people don’t really know how it works. Because of this, we’re going to review how solar power works.

Solar power works because of solar cells, or photovoltaic cells as they are also called. Photovoltaic cells capture sunlight and covert it directly into clean electricity, which is then piped through wires and cables to whatever needs the power. Solar cells come in all sizes and can be used to power everything from mobile electronics to an entire house or factory.

Solar cells are made of powerful materials called semiconductors, and when light strikes the cell, some of it is sucked in to the semiconductor material. This energy then loosens electrons, and the electrons are forced through wires. This movement of electrons is called a “current,” and when metal connectors are attached to each side of the solar cell, the current is sent to power whatever it’s attached to.

However, since solar cells require sunlight, they don’t work as well on cloudy days, and obviously not well at nighttime. The way modern solar systems get around this limitation is by attaching the photovoltaic cells directly to a rechargeable battery. Then, at night or on cloudy days, built up energy can be used to continue to power what it’s attached to.

Regular advancements are being made in the solar power field and each year, solar cells become more and more efficient, meaning that they are able to create more power with less sunlight. Look closely for new solar products and applications that can be used to make your life easier and greener through solar power and solar cells.
