Original title: Tesla launches oversized solar roof: 190,000 yuan to produce 77 kilowatts of electricity per day

In September of this year, Tesla launched the official website of its solar energy business, and the main product of this business, the household solar cell roof, was also on the shelves.

At the time, the official website offered a total of three sizes: small, medium, and large. The lowest price was 1,1273 US dollars (about 78,000 yuan), but Tesla would return the monthly revenue for the additional electricity supply. After conversion, the lowest price was 7,891 US dollars, or about 55,000 yuan.

Recently, according to foreign media reports, Tesla also launched an X-Large (X-Large) solar roof product. This product is suitable for houses (Houses) of 370 square meters or more. After Tesla's monthly cashback is taken into account, the lowest price is 27,365 US dollars, about 190,000 yuan. The official website shows that an oversized solar roof can produce an average of 58-77 kilowatt-hours of electricity per day (1 kilowatt-hour = 1 kilowatt hour) of electricity.

However, Tesla's solar energy business is not as reliable as Tesla's car. Previously, Tesla and its solar panel subsidiary SolarCity caused fires in the rooftop solar panel systems of seven Walmart stores due to gross negligence and caused Walmart millions of dollars in losses. Walmart also filed a lawsuit against Tesla in response.
