Why the Next Microgrids Will Be Well Connected

Cars That Think

Several factors combine to make Puerto Rico an ideal place for solar power and microgrids. The island gets on average nearly 3,000 hours of sunshine per year, putting it on a par with Honolulu and Brisbane, Australia. During and after Maria, Casa Pueblo continued to operate a solar-based microgrid it had installed in 2017.
