The energy the Earth receives from the sun, primarily as visible light and other forms of electromagnetic radiation, is a powerful source of energy. The technologies that are utilized in this segment are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
A photovoltaic utility-scale power station, also known as a Solar Farm, is a large-scale photovoltaic system (PV system) designed for the supply of solar energy into electric power and feeds the electricity grid. They are differentiated from most building-mounted and other decentralized solar power applications because they supply power at the utility level, rather than to a local user or users.
A utility-scale solar field through solar panel arrays harnesses solar energy and, through photovoltaic cells and invertors, generates electricity that needs to be boosted in voltage levels to make them useful for transmission. This is where VTC designs and manufactures to the onerous harmonic loads of the solar energy segment. VTC’s pad mount transformers again catalogued as E2X to serve as Inverter Step-Up (ISU) to step up the voltages from solar panel arrays and collectively feeds a collector power transformer at the substation also known as Main Power Transformer (MPT). Here again, VTC designs and supplies MPTs large power transformers that boost the voltage levels to synchronize with the grid voltages.
