Solar Energy: 10 Major Application of Solar Energy – Explained!
Photo-voltaic cells (Introduction, application, uses)
Aside from those two reasons, the world is also looking for renewable and sustainable sources of energy in order to protect and reduce the harm caused to the enviornment. As you may have already noticed, the deterioration of the environment is highly correlated to the production and usage of fossil-based fuels world wide. As a matter of fact, the United Nations has created a new mechanism to encourage the utilization and development of renewable energy resources like solar panel technology, whether in small-scale, commercial or industrial scale. This strategy that the UN created is called the carbon credit market through the Kyoto Protocol. According to researchers, the Earth absorbs a total of 3. This fact alone tells a lot about the great potential of solar energy on a wide spread basis. Given all of the above information, it just makes sense for the world to invest in solar energy technologies.
Photovoltaic PV devices generate electricity directly from sunlight via an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit, powering electrical devices or sending electricity to the grid. PV devices can be used to power anything from small electronics such as calculators and road signs up to homes and large commercial businesses.
Most solar cells are a few square centimetres in area and protected from the environment by a thin coating of glass or transparent plastic. A solar, or photovoltaic PV , module generally consists of 36 interconnected cells laminated to glass within an aluminum frame. In turn, one or more of these modules may be wired and framed together to form a solar panel. Solar panels are slightly less efficient at energy conversion per surface area than individual cells, because of inevitable inactive areas in the assembly and cell-to-cell variations in performance. The back of each solar panel is equipped with standardized sockets so that its output can be combined with other solar panels to form a solar array.
