photovoltaics panels
A solar panel is a device that uses energy from the sun and converts it into other forms of energy that humans consume for a variety of purposes. Solar panels utilize solar cells. A famous type of solar panel, also known as the photovoltaic panel, uses light energy from the sun and converts it into electricity. Another kind of solar panel is the solar thermal energy panel which is a form of solar energy storage. And of course, one of the more popular and highly useful forms of solar panels is the solar hot water panel which heats water with energy coming from the sun.
In order to understand how solar panels work, one must be familiar with the composition of a solar panel. For instance, the photovoltaic panel is made up of interconnected photovoltaic or solar cells. Solar cells are devices made from silicon that has the property to convert solar energy into other forms such as electricity and heat energy. When these solar cells are packaged together either through wiring or fastened installation, they become one solid panel. For protection, the panel may be covered with fiberglass, plastic, or even metal.
Solar panels work in a way that may be simplified into to steps: light absorption and energy conversion. Solar cells are light-absorbing materials and they have high energy conversion capabilities. The silicon contained in the solar cells of a solar panel makes light absorption possible. The sun’s rays emit photons and these are then absorbed by the silicon atoms.
Silicon has the property to create electricity if it is bonded with another element that will produce the positive charge needed. Naturally, silicon has four electrons. In order to generate electricity, silicon atoms must be paired with an element that can knock off the extra electrons and make room for a positive charge. The photon coming from the sun ensures just that.
And so, when the sun’s photons are absorbed by the silicon atoms, the atomic composition of the solar panel is arranged in such a way that electricity is generated. This energy is then passed on to installed electrical wiring within the solar panel right down to the power generating device connected thereto.
In summary, solar panels work in such a way that it acts as connector and energy transformer between the sun and whatever purpose man has for the sun’s energy. It acts as a middleman of sorts. The sun gives off its photons through its rays, and the solar panel absorbs these through its solar cells. The light absorbed is then converted into electricity within the solar panel device and it is passed on through a power generating device that makes possible whatever use the solar panel should serve: may it be for solar energy, heat energy, or simple electricity.
