About Tesla

Tesla, founded in 2003 in Palo Alto, California, initially focused on electric vehicles but expanded into clean energy solutions, including solar batteries, through its acquisition of SolarCity in 2016. The company leverages its expertise in lithium-ion battery production from its Gigafactories, producing over 100 GWh annually by 2023, to deliver integrated systems that emphasize energy independence and smart grid interaction. Tesla batteries integrate tightly with solar setups, with software-driven optimisation that can reduce household energy bills by up to 50% in optimal conditions through features like time-of-use shifting and virtual power plant participation. In Australia, Tesla has maintained a strong presence since 2015, with local installers and support teams handling over 100,000 Powerwall installations nationwide, backed by the company's financial stability as a NASDAQ-listed entity. While the systems offer high power output and scalability, allowing stacking up to 10 units for commercial-like capacity, users should note that real-world efficiency can vary based on installation quality, and customer service response times have occasionally been reported as inconsistent during peak demand periods. Tesla's 10-year warranty guarantees 70% capacity retention, with options for extended coverage, underscoring a commitment to durability in Australia's variable climate.
