Running a Tesla just got cheaper
CONFIRMING the carefully leaked rumours that had been doing the rounds for months, Edison International and Tesla last week launched battery packs that promise to make solar power affordable.
The greeny dream is to use the cheap sunshine to power our lives, but storing that power as electricity has so far been too expensive to compete with burning wood or fossil fuels.
Enter the Tesla Powerwall Home Battery — the first batteries that do not “suck” at being batteries, according to Tesla founder Elon Musk.
A seven-kilowatt-hour version will sell for $3 000, (about R36 200) and a 10-kWh version will sell for $3 500 (R42 222) to electricians who will install the wall-mounted units.
The powerpacks are made with Southern California Edison (SCE), a subsidiary of Edison Energy that provides rooftop solar systems.
Tesla is also testing 100-kWh batteries that will not be wall mounted but assembled into grid-storage arrays ranging from 500 kWh to 10 MWh in capacity.
SCE is working with Tesla to show how homes and businesses can turn sunlight into electricity. One such business is Cinemark Holdings, Inc., which installed Tesla batteries at two of their theatres in Southern California.
Next up, the industry awaits battery banks where consumers can exchange a discharged battery pack with a charged one to continue a journey.
The full-electric Tesla S burning rubber — the latest spin-off from Tesla — is a lot greener, in the form of cheaper batteries that will make using solar power more affordable.
