Why did Long Island solar farm keep a transformer onsite?

Due to the long lead time, the Long Island Solar Farm chose to keep a spare transformer onsite, as transformer failure would have kept the solar farm offline for a long period. [ 83 ] Transformers typically have a life of 25 to 75 years, and normally do not require replacement during the life of a photovoltaic power station. [ 84 ]

What is the global PV capacity?

Total capacity of worldwide PV plants above 4 MW AC was assessed by Wiki-Solar as c. 220 GW in c. 9,000 installations at the end of 2019 [ 1 ] and represents about 35 percent of estimated global PV capacity of 633 GW, up from 25 percent in 2014. [ 178 ][ 176 ][needs update] Activities in the key markets are reviewed individually below.

Where are photovoltaic power stations deployed?

The US deployment of photovoltaic power stations is largely concentrated in southwestern states. [ 12 ] The Renewable Portfolio Standards in California [ 198 ] and surrounding states [ 199 ][ 200 ] provide a particular incentive.

Which country has the largest solar power plant in the world?

India has been rising up the leading nations for the installation of utility-scale solar capacity. The Charanka Solar Park in Gujarat was opened officially in April 2012 [ 188 ] and was at the time the largest group of solar power plants in the world.

Which countries have photovoltaic power stations?

The USA, [ 12 ] China, [ 13 ] India, [ 14 ] France, [ 15 ] Canada, [ 16 ] Australia, [ 17 ] and Italy, [ 18 ] among others, have also become major markets as shown on the list of photovoltaic power stations. The largest sites under construction have capacities of hundreds of MW p and some more than 1 GW p. [ 19 ][ 20 ][ 21 ]

Where are solar power stations located in Spain?

The majority of the deployment of solar power stations in Spain to date occurred during the boom market of 2007–8. [ 196 ][needs update] The stations are well distributed around the country, with some concentration in Extremadura, Castile-La Mancha and Murcia. [ 10 ]
