Solar Solution for Commercial
Overview
Most Solar parks are ground mounted PV systems, also known as free-field solar power plants. They can either be fixed tilt or use a single axis or dual axis solar tracker. While tracking improves the overall performance, it also increases the system's installation and maintenance cost. A solar inverter converts the array's power output from DC to AC, and connection to the utility grid is made through a high voltage, three phase step up transformer of typically 10 kV and above. The generic expression utility-scale solar is sometimes used to describe this type of project. Photovoltaic power station, also known as a solar park or solar farm , is a large-scale photovoltaic system (PV system) designed for the supply of merchant power into the electricity grid. Most solar parks are developed at a scale of at least 1 MWp.
System structure
Utility-scale solar plant typically includes solar panels, inverter, step up transformer, mounting frames, trackers and utility grid.
Advantages
l Solar energy is sustainable and endless, and available in all areas of the world every day.
l The power generated by solar park can be used for diverse purposes for example electricity supply, distilling water, powering satellites in space, integrating into building materials, etc.
l Solar power systems generally don’t require a lot of maintenance
l There are no moving parts, there is no wear and tear
l After covering the initial cost of the solar system, very little spending on maintenance and repair work.
l Profitable investment in long term.
Most of the existing large-scale photovoltaic power stations are owned and operated by independent power producers, but the involvement of community and utility-owned projects is increasing. To date, almost all have been supported at least in part by regulatory incentives such as feed-in tariffs or tax credits, but as levelized costs have fallen significantly in the last decade and grid parity has been reached in an increasing number of markets, it may not be long before external incentives cease to exist.
