Utility-scale solar

Summary

Utility-scale solar is large scale (sometimes defined as greater than 1 MW[1] or sometimes 4 MWAC ) solar power either from:

A photovoltaic power station at a scale large enough to be classified as 'utility-scale'; or Concentrated solar power whereas rooftop solar is usually smaller. The utility-scale solar sector has led the overall U.S. solar market in terms of installed capacity since 2012.[2] Increasingly batteries are co-located,[3] in order to sell into the evening peak of the duck curve.[4] Output voltages reach 1000VAC as of 2021.[5] They can sometimes be agrovoltaics.[6]

Utility-scale refers to electrical plant or equipment, whose operation, as an individual entity would cause a noticeable change in the operation of a utility.[citation needed] For example, a single domestic PV panel, on its own has no discernible effect on the operation of a power network. A 1 MW installation can impact on local voltage, and disturb system frequency.

In some countries it is competitive with wind power.[7][8] In many countries it is cheaper than new fossil fuel power plants and in a few in the Middle East is becoming cheaper than existing fossil fuel plants as of 2021.[9] The cost reduction is expected to spread to other countries.[9]
