1500 volt architecture is taking the utility-scale solar sector by storm. As the latest evidence of this, Phoenix Solar today announced that a 65 MW solar PV project which it will build for Invenergy in rural Nevada will incorporate 1500 volt architecture.
There are multiple advantages of moving from 1000 to 1500 volts. While individual electrical balance of systems components are more expensive, 1500 volt systems use fewer such components and require less installation labor. GTM Research Solar Analyst Scott Moskowitz says that the value proposition for 1500 volt systems is clear.
Moskowitz estimates that only a few hundred megawatts of solar projects have been built using 1500 volt architecture to date. And while deployment has been led by a few early movers including First Solar and NextEra, he says that a significant pipeline of 1500 volt projects is already under construction. A report Moskowitz authored in January predicts that 4.6 GW of 1500 volt projects will be built globally this year.
This announcement is not an anomaly, Moskowitz told pv magazine. This is just further proof that the technology is ready and is beginning to be implemented at a significant scale.
Phoenix Solar also plants to utilize single-axis trackers for the Luning Solar Energy Project, as well as multicrystalline silicon PV modules. The plant will be located on public land managed by the U.S. Bureau of Land Management (BLM) in Nevadas Mineral County.
?Phoenix Solar will be responsible for engineering, procurement and construction for the project, and expects to begin construction by the end of the first quarter of 2016.
