Tesla is working to build a new structure at the Fremont plant that will include a solar roof to test the latest version of Tesla's solar power product.
When Tesla launched Solar Roof Tiles in 2017, the automaker said they would begin volume production and installation in 2018.
However, the rollout proved to be much slower and installations have been limited to the homes of some executives and a few customers.
Tesla later delayed volume production to 2019.
CEO Elon Musk said they had to make some changes to the product to ensure it will last for 30 years.
At Tesla's shareholders' meeting in 201[ads1]9, Musk said that they are now completing a third version of the Tesla sunroof:
“We are in the process of completing version 3 of the sunroof. This is actually a rather difficult technology problem to have an integrated solar cell with a roof tile, keep it well and last for 30 years. "
The CEO explained that they were having difficulty doing accelerated roof testing, but they now feel more secure.
Now we are told that Tesla is planning to build a "test structure" for the roofing roofs at Fremont Factory, according to a building permit obtained last month (via CNBC):
According to the description in the building permit, it would be to test both the product and the installation process:
“Building a test structure to evaluate the Tesla solar roof roof and installation process. Fire Sprinklers, Fire Alarms, Truss Design and Solar Design are exposed submissions. "
First launching the new product, Tesla said it should take about the same time to install a sunroof as a chip roof installation, which is typically 5-7 days.
Earlier this year, we reported that the Tesla Solar Roof installation still took about two weeks, increasing the cost of the product, but that was before the solar roof V3.
Last month, Electrek released a first look at Tesla's V3 solar roof technology with custom fittings and the first real Tesla Solar Roof quote. The price was shockingly high, but Tesla claims it is worth adding the power savings over time.
Earlier this week, Musk said Tesla plans to set Solar Roof Tile production to 1,000 roofs per week by the end of the year.
