Tesla has reduced the size of the planned solar array at Gigafactory Nevada, but it still plans to make it the world’s largest. Tesla revealed plans for a massive 70 MW rooftop array at Gigafactory Nevada in 2017, which would be the world’s largest rooftop array by a long shot. For a long time, the project has been languishing. Tesla began construction on the solar array in 2018 and continued to expand it over the next few years, although it has never reached the size Tesla has claimed.
Tesla provided an update on the project today with the publishing of its 2020 Impact Report, confirming that it has now deployed 3.2 MW on the factory’s rooftop. Also, Tesla is no longer referring to 70 megawatts. The Tesla Gigafactory Nevada solar array will be expanded to 24 MW by the end of 2022, according to the company. Tesla continues to claim that it will be the country’s largest solar rooftop installation.
Tesla says, “Gigafactory Nevada was designed to be covered with solar panels. to date, we have installed solar panels with a capacity of 3,200 kW. This installation will grow to about 24,000 kW – the whole roof of the current building structure – by the end of next year. This will make it the largest rooftop solar installation in the US.”
To be fair, there are solar farms with far larger capacity than 24 MW, but Tesla is referring to rooftop solar arrays rather than ground-mounted installations. More solar capacity is also being installed at the automaker’s Fremont factory, Lathrop facility, and Gigafactory New York, according to the company.
