Gigafactory 1 Finally Getting Rooftop Solar

FEB 28 2018 BY MARK KANE 26

In February, Tesla began installation of solar panels on the roof of battery Gigafactory 1 in Nevada.

This news comes via the latest satellite photos provided by Building Tesla.

Tesla was expected to install solar panels from the beginning when it presented the Gigafactory visualization image. Around one year ago, the company even announced a 70 MW solar installation – combination of rooftop solar and ground installation.

The ultimate goal for the facility is to be 100% powered from solar, which in Nevada shouldn’t be problematic.

The rooftop solar installation itself is expected to be several times larger than any other rooftop solar simply due to the size of the Gigafactory 1 building.

It’s not yet been announced whether solar panels are provided internally from Gigafactory 2 where solar products are made by Tesla and Panasonic.

Any delay was a good thing. It means that the panels being installed now are even more powerful and less expensive

And that is why Solar City collapsed.

So… SolarCity “collapsed” because of the solar panel factory that only went into production after being bought out by Tesla.

Ummmm… right. This is what passes for “logic” and “facts” among serial Tesla bashers like Six Pretend Electrics. 🙄

You are patently a sixpence short of a shilling.

And made by Tesla/Panasonic themselves in the Giga 2.

Too bad Trump levied a 30% Duty on imported solar panels

Please explain to me why this is bad again?? Trump levies 30% duty on imported solar panels. The imported solar company then creates a plant in the US that employs American workers. So this is bad??

It’s bad for the solar industry and its expansion but good for the US solar manufacturers. Just another law that was meant to protect businesses and screw the general public but in the end will probably negatively affect the solar installers and they represent the biggest part of the solar industry. This comes as no surprise since the unrelenting push by the big utilities to slow solar down. It may look like a protectionist move at first but it’s definitely just good ole money making thieir way through the political elite and paying for laws and regulations.


Trump only wants to slow solar energy production, and the tariff will do exactly that. The tell is Trump’s budget proposal, which slashes 70% of the alternative energy research budget.

Now if he had boosted that alt-energy budget and imposed tarrifs then your view would make sense, but of course to do that would require the courage to stand up to the fossil fuel industry.

Because factories are very automated and employ relatively few people compared to field installation that require boots on the ground at the site. There will be far more jobs lost (or more likely, not created) due to higher module prices depressing the number of installations than will be created by any increase in domestic demand for modules. Even worse, with a 30% import tax, it’s probably still cheaper to buy Chinese modules at 130% of Chinese prices than 100% of domestic prices, so the change will add zero manufacturing jobs while decreasing installation jobs (and all of the related design work, etc. for projects that now don’t pencil).

^^ This

They didn’t make the tariff high enough to force companies to move to the US and push down US manufacturing costs, and yet they made it too high for many people to now afford to install their own solar.

It is a lose-lose, and foreign solar companies will simply double down on all of the many markets outside of the US for growing their companies. China is a massively booming domestic solar market, and the EU and India are also growing.

The tariffs last only four years. So any big investments in solar will again be subject to Chinese dumping long after tRUMP is gone, making investment more risky.
It’s sabotage, plain and simple. The Koch’s are not fools, they got what they paid for.


The next 2.5 GW of imported solar panels are still tax free, that is 4-5 years of imports. Thus only the next (probably democratic) president will have to mess around with China because of this. Devilishly clever ….

And Trump is setting up the next president with a nice flaming bag of poo on the White House doorstep in the form of humongous budget deficits that will require substantial tax increases to pay down.

It’s not that this stuff is clever, it’s that the GOP voters are so gullible they make it look clever.

How are you coming up with 2.5GW lasting 3 to 4 years? That’s about how much was installed just last quarter.

Substitute stupid for gullible and you would be more correct.

I can’t wait to see batteries being made from solar power so that I can proudly tell anti-ev folks to STFU LOL

Excellent. Finally we are seeing solar panels and this will excite everyone.

Solar panels first block the sunlight from hitting the roof and this will reduce the heat inside the building. On top of that, it will generate electricity.

Bingo, power saving + power production.
I guess this will reduce the coal/natgas used in power generation.

After completing the installation of solar panels on the building, it should be placed on top of parking lots as well. This will protect the cars from excessive heating and can also charge the electric vehicles.

Hurrah, and the additional idea of a solar panel covered parking lot make a lot of sense in that part of Nevada.

“The ultimate goal for the facility is to be 100% powered from solar, “

I distinctly remember the ultimate goal was to be 100% powered by renewable energy.

In practice this means it will be powered by wind also.

Does that follow? What are the wind characteristics near the Gigafactory? Will the solar roof produce enough power so that excess can be stored?
The initial ‘renewables’ statement was probably true but solar efficiency advances and cost reductions make it replaceable by ‘solar’ alone.

“What are the wind characteristics near the Gigafactory?”

Not relevant. We have a grid that can transport the power from wherever these turbines are installed.

Thanks to the NREL there is a wind resource map of the US:

And more specifically, of the Nevada:

There are quite a number of level 5 and 6 regions (on a scale that goes to 7). So yes, Nevada is attractive for both solar and wind power.

“Will the solar roof produce enough power so that excess can be stored?”

Not a snowball’s chance in hell. Factories are very energy dense (as in: average power consumption per square meter). The rooftop solar will provide at most a few percent of total energy.

This was supposed to be my reply to jimjfox…

And what about on the Fremont facility? Electricity is way more expensive in CA
