The company ran a solar energy micro-grid on American Samoa’s Ta’u Island using over 5,328 solar panels and 60 Tesla Powerpacks. The entire system, at 1.4 megawatts, that offers 6 megawatt-hours of energy storage, can collect solar power and store it for up to 3 days.
It took the entire island one year to complete the switch over to solar power, which should be enough to keep them powered 24/7.
The Island of Ta’u with its paradise-like weather and a population of fewer than 600 residents with relatively modest power needs, was previously powered using diesel fuel generator, that burns 300 gallons of fuel per day, which is neither eco-friendly nor cheap.
So this switch is a much welcomed eco-alternative.
Although Tesla considers this project a small test, it has demonstrated the possibilities and feasibility of micro-grids in a much larger way.
