It doesn’t have as much allure as a hot tub or a splash pool, but here’s the first Aussie family to have a Tesla Powerwall unit installed in their home.

Oh, you’re still here, we’ll carry on then.

The Tesla Powerwall is of course the brain child of Elon Musk, aimed at allowing houses to store solar power more effectively and thus reduce their energy usage dramatically. More from AFR:

The Powerwall is a rechargeable lithium-ion battery (the same type of battery used in Tesla’s Model S electric car) that is designed to store energy — whether that be from solar power, or load shifting to reduce your electricity bill if you’re still connected to the traditional grid.

The installation at the Pfitzner house in Kellyville Ridge was carried out by Natural Solar…

Home owner Nick Pfitzner says he expects to see a return on investment in less than eight years. A Powerwall battery will set you back close to $10,000 if you already have solar panels installed on your house. If solar installation is necessary you’ll be looking at paying upwards of $18,000

“I’ve been watching Tesla since the Roadster was first released, as I work in IT and was quite a fan of Elon Musk in general. When it was announced last year that they were moving into household energy storage, I jumped onto the official Tesla reservation list,” Pfitnzer said.
