Elon Musks company,  Tesla,  has used its solar panels and batteries to restore electricity at San Juan’s Hospital del Niño (Children’s Hospital), in what SpaceX and Tesla founder Elon Musk calls “the first of many solar+battery Tesla projects going live in Puerto Rico.”

The project came about after Puerto Rico was hit by two devastating and powerful hurricanes in September, and Musk reached out about Tesla helping.

Musk’s company announced its success in getting the hospital’s power working again less than three weeks after Puerto Rico Gov. Ricardo Rossello tweeted on Oct. 6, “Great initial conversation with @elonmusk tonight. Teams are now talking; exploring opportunities.”

Tesla’s image of the project’s solar array, in a parking lot next to the hospital, has been liked more than 84,000 times since it was posted to Instagram Tuesday.
