Question:

what do solar panels do?

???

Answer:

Solar panels (or photovoltaic panels) collect either light energy (photons) or heat which is then used as energy. Because a single panel can only produce a limited amount of power, there are normally more than one installed.
The solar panels are made of solar cells. A cell is a small disk of a semiconductor like silicon. They are attached by wire to a circuit. As light strikes the semiconductor, light is converted into electricity that flows through the circuit. As soon as the light is removed, the solar cell stops producing power.
Solar panels (arrays of photvoltaic cells) make use of renewable energy from the sun, and are a clean and environmentally sound means of collecting solar energy. Here at solar panel information, we've amassed a wealth of information relating to solar panels and the field of photovoltaic technology. You can learn how solar panels work, how they are manufactured, where to buy them, and how to set them up. If you are looking for information on solar panels and don't know where to start, check out our solar panels section to learn more about how these photovoltaic cells are derived from silicon and what solar energy means to you.
Hi okorder
The cost of electricity is increasing at a rate of 5 to 0 percent every year with no end in sight. A solar panel system captures the (free!) sun and turns it into usable electricity for your home.
