Back in 2015, automaker Tesla Motors set its sights on the home energy storage market and announced the launch of its home battery product, the Tesla Powerwall.

In the past, Tesla Motors has been praised for making high-quality electric vehicles, as well as for their ability to reimagine and successfully rebrand existing technologies. In fact, while Tesla’s automobiles revitalized the 21st-century electric vehicle market, the first electric cars were invented more than a hundred years earlier.

Tesla’s rebranding of residential-use batteries is in line with their legacy of reimagining existing products. Tesla’s battery may represent the first time in history that everyday homeowners are truly excited about the potential of storing energy at their home. The Powerwall, combined with the exciting Tesla Solar Roof, are both potential cornerstones of Elon Musk’s sustainable energy vision for the future.

A partnership between Tesla and KIUC’s (Kauaʻi Island Utility Cooperative) — is vast — 45 acres of solar panels situated among rolling green hills. Panels dip and rise with the contour of the land, feeding the energy of the sun to a 53MWh array of Tesla Powerpacks — white boxes filled with batteries. That’s more than double that of Tesla’s battery Powerpack project in California.
