The situation of such Tau Island has changed completely, the storage battery of mega solar power plant and Tesla " Powerpack"Together Micro grid. " On Tau Island all the electricity necessary for the life of the island, such as a pump sucking up water that all islanders need, and facilities such as hospitals, schools, and police depended on diesel generators, so if the fuel is on the bottom If so, the islanders are going out of crisis by limiting electricity to only morning to afternoon. Keith Ahnson, born in Tau Island, said, "In the early childhood, we were unable to contact a contact vessel connecting the mainland and the island for two months, and we could not purchase fuel from diesel generators. SolarCity, a company that introduced solar panels acquired by Tesla on such Tau Island, installed a mega solar power plant, so a clean remote island that can live only by sunlight appeared. Until now the islanders of Tau Island have relied on diesel generators to generate the main electricity, but there is no way to buy the fuel with the boat connecting the mainland and the island, sometimes the fuel shortage occurred Thing. It is 4000 miles (about 6437 m) away from the West Coast of the USA American SamoaIsolated island " Tau IslandAbout 600 people of the islanders live. Tesla is clearly hoping this acts as an example to other potential customers, and it also shows at commercial scale why Musk believes the solar battery portion of the business will one day exceed the market for Teslas – there are plenty of spots where reliable, independent power holds more appeal than an electric vehicle.08:02:00 "Ta'u Microgrid" realized Tesla's ideal of solving the entire island with photovoltaic power generation and batteries The project was funded by the EPA, the Department of the Interior and the American Samoa Economic Development Authority. Start to finish, Tesla and SolarCity’s Ta’u microgrid project came together within a year. The resulting micro grid can provide three full days of power for the island’s 600 residents at max capacity, and recharges fully after just seven hours of solid sunlight exposure. The Ta’u grid project involved creating a SolarCity panel array made up of over 5,300 panels capable of generating 1.4 megawatts of solar capacity, combined with a Tesla Powerpack commercial battery storage facility with 6 megawatt hours of reserve capability across 60 Powerpacks. Solar’s costs are typically recouped over a long period of time when grid power is convenient and readily available, but the financial benefits should accrue much more quickly when you’re shipping in and burning fuel as your only source of energy. But use of a fuel that must be shipped in at considerable cost and from a great distance poses a number of problems, and leads to a lot of temporary blackouts. The diesel reliance isn’t new – a lot of island communities rely on burning the fossil fuel in order to maintain an electrical grid. The SolarCity blog details a project in which SolarCity power generation and Tesla Powerpack-based storage helped the small island of Ta’u in American Samoa fix its spotty power problem and cut its reliance on a diesel generator grid. Tesla and SolarCity’s union is still very fresh, but the combined companies are already highlighting what they’ve been able to accomplish even just as partners.
