Tesla’s roof with integrated solar cells is gaining momentum. The company led by Elon Musk has just started full-scale manufacturing of its latest big bet for solar technology at its factory in Buffalo. In the line of sight of the company; this annual production reaches 2 gigawatts, which is doubled compared to the initial expectation for 2019.

To achieve this goal, hundreds of employees equipped with specific machines have been mobilized in the more than 111,000 square meters that make up the company’s facilities in western New York State. In them, the Tesla staff will combine photovoltaic cells produced by Panasonic Corporation and tiles that shape this inexpensive and durable solar system and, above all, so integrated into the roof that it goes unnoticed.

Although the sale of Tesla’s integrated solar roof had already started months ago thanks to the pre-reservation system, which is why its small-scale production was also underway near the company’s plant in Fremont, California; the work undertaken in Buffalo represents a qualitative leap.

This is how JB Straubel, chief technology officer of Tesla sees it, who, in statements gathered by AP News, pointed out that by the end of the year, the increase in production of these solar roofs will be substantial. “This is an intermediate step of which we are very proud”.

With him, you will answer the “Strong demand” of these built-in caps, which is why Tesla will work until the end of this fiscal year to fulfill the orders received.

But beyond that, Tesla’s intentions are that the production from its integrated solar roofs in Buffalo is approximately 2 gigawatts. The target doubles that previously announced for 2019, which had been set at 1 gigawatt. This is equivalent to the annual output of a large nuclear power plant, or a coal-fired power plant, according to Straubel.

Thus, Tesla is moving to supply the market with its roofs with integrated solar cells, a solution presented in the fall of 2016, after the acquisition by the company led by Musk of the solar panel installer SolarCity for $ 2 billion.

The merger has allowed Tesla to position itself in the domestic solar energy market, with its solar roofs as its main asset. Musk himself and his CTO were among the first to take advantage of the system, which is booming in production at the Buffalo Gigafactory.
