How do Solar Panels (PV systems) Work?
Does all the scientific terminology in the solar industry intimidate you? Well, fortunately… it’s simpler than you think!
Solar energy has been around for a very long time. Some anthropologists believe that as early as 7th century BC, early humans were using magnifying glass materials to start their own fires.
Solar energy and photovoltaic systems have been around for over 100 years. In 1839 Edmond Becquerel, a French scientist, discovered photovoltaic energy and the “photovoltaic effect”. Becquerel has uncovered the theory that light could boost electricity generation when a conducting solution has two metal electrodes places into it. Thanks to Edmund Becquerel, we know understand how cells within a solar system panel convert sunlight to electric energy. These scientific revelations later led to the discovery of silicon cells, and by 1955 were being marketed by a company called Western Electric.
Solar cells and solar energy is produced with the following:
1. Light which is absorbed through the PV system knocks electrons loose
2. These electrons which have come loose then creates a current of energy
3. This energy and current is encapsulated and transferred through to wires
The most important feature of a solar panel is the photovoltaic cell. This cell is what generates and converts energy using what is called the “photovoltaic effect”. Sunlight which is absorbed creates electric currents which are used to generate energy. The power of a single cell in a PV system is about two watts. However, when solar panel array is installed and multiple cells are placed together, a solar energy panel installation can generate thousands of electric KW for a large residential household.
What Types of Solar Cells are there?
Two types of solar cells are common today – monocrystalline and polycrystalline. Monocrystalline and polycrystalline cells are popular for residential and commercial usage. Monocrystalline cells are made using the element silicon, while polycrystalline cells are created through melting many silicon crystals together.
Monocrystalline cells are generally more efficient, as they allow the flow of electrons/energy to be more easily dispersed and transferred. Contrary to the polycrystalline cells, monocrystalline have a single silicon crystal. Polycrystalline cells, on the other hand, are less expensive, due to its convenient manufacturing process. The energy flow for polycrystalline cells is far more challenging than monocrystalline.
Innovation – Generating from the Sun
Solar energy is an innovative solution. Through capturing energy from the sun, humans are able to harness both heat and electricity. With each decade, the demand for solar energy grows and becomes more alluring, especially given the unending supply of energy, and the environmental appear.
The power of a single cell in a PV system is about two watts. However, when solar panel array is installed and multiple cells are placed together, a solar energy panel installation can generate thousands of electric KW for a large residential household.
