PV PANELS
"Photo voltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. KBP is dealing with four kinds of pv panels they are as follow"
Thin Film
A thin-film solar cell (TFSC), also called a thin-film photo voltaic cell (TFPV), is a solar cell that is made by depositing one or more thin layers (thin film) of photovoltaic material on a substrate. The thickness range of such a layer is wide and varies from a few nanometers to tens of micrometers.
Thin film solar panels are commercially available for installation onto the roofs of buildings, either applied onto the finished roof, or integrated into the roof covering. The advantage over traditional PV panels is that they are very low in weight, are not subject to wind lifting, and can be walked on (with care). The comparable disadvantages are increased cost and reduced efficiency.
Mono Crystaline
Monocrystalline Silicon is made from very pure Monocrystalline Silicon. Monocrystalline Silicon has a single and continuous crystal lattice structure with practically zero defects or impurities. One of the many reasons Monocrystalline Silicon is superior to other types of silicon cells are their high efficiencies - which are typically around 15% and higher for the TOP-Class. Because the manufacturing process required to produce Monocrystalline Silicon is more involved and detailed than other types.
Monocrystalline photovoltaic electric solar energy panels have been the go-to choice for many years, and are among the oldest, most efficient, and most dependable of technologies. Each module is made from a single silicon crystal, and is more efficient. The lifespan of a GOOD monocrystalline cell is a minimum of twenty-five years and can be more than fifty, making them a worthwhile investment for long term use.
Poly Crystaline
Polycrystalline silicon photovoltaics are a type of solar cell. Silicon solar cells are manufactured with a microstructure tailored to the application depending on economic and performance requirements.
Polycrystalline silicon is composed of many smaller silicon grains of varied crystallographic orientation. This material can be synthesized easily by allowing liquid silicon to cool using a seed crystal of the desired crystal structure. Additionally, other methods for crystallizing amorphous silicon to form polysilicon exist such as high temperature chemical vapor deposition (CVD).
Concentrated PV Panel
Concentrated photovoltaic (CPV) technology uses optics such as lenses or curved mirrors to concentrate a large amount of sunlight onto a small area of solar photovoltaic (PV) cells to generate electricity. Compared to non-concentrated photovoltaics, CPV systems can save money on the cost of the solar cells, since a smaller area of photovoltaic material is required.
CPV also competes with concentrated solar thermal. CPV turns the sunlight directly into electricity, while solar thermal turns the sunlight into heat, and then turns the heat into electricity. Solar thermal is far more common than CPV, although the two technologies are sometimes combined..
