Kurzweil predicts solar industry dominance in 12 years – that’s a lot closer than you think

Nellis_AFB_Solar_panels

Ray Kurzweil is known for inventing things, wanting to live forever, The Singularity and – of relevance in this article – Exponential Growth of technology, like solar power. Recently, during a medical device presentation, Kurzweil reiterated his predictions that solar power will continue to double its global capacity every two years and six more times in the next twelve years. Some charts look suspiciously like they’re shooting upward just ahead of his predicted pace. Personally, being in the field day to day, as a Project Developer, it is hard to believe that solar power might install such volumes in the next twelve years – but ten years ago, when I got into the industry, I never thought it’d grow like it has.

Elon Musk invests in SolarCity (again) with Rive and Silver Lake – $113 million total

elon-musk1During the past few months, rooftop solar installer SolarCity has been watching its stock price plummet, along with most of the solar industry. During the past week, Chairman Elon Musk bought 3 blocks of shares between $25.20 and $26.45 to add over 500,000 shares to his now total of 21.3 million shares or about 21% of the company.

Now just a few days after the disclosure of the stock purchase, we learn through a press release from Silver Lake Kraftwerk that Musk invested an additional $10 million in the company through convertible senior notes along with $100 million from Silver Lake and $3 million from SolarCity CEO and Musk’s cousin, Lyndon Rive.

SolarCity plans on producing $0.50/Watt solar modules with at least 20% efficiency

SCTY_riverbend

Yesterday SolarCity released a SEC filing listing the milestones its co-founders need to achieve to vest tranches of shares of their new performance-based compensation plan. The milestones reveal some ambitious goals for the solar installer.

For example, the first milestone is to achieve a cost of production of $0.50/Watt for solar modules with at least 20% efficiency.

Elon Musk buys $5 million worth of SolarCity’s stock during global market correction

green energy jobs

solarcity_installersThe global stock market had a horrible day. Even Wall Street darlings like Google and Apple saw billions of dollars trimmed off their market capitalizations. A surprising exception, SolarCity, the largest residential solar installer in the US, managed to go against the grain and closed the day with an impressive 7% gain thanks to its Chairman and major shareholder Elon Musk who bought another $5 million worth of shares during the stock’s price fall to add to his holding in the company now worth over $900 million of SolarCity’s total market cap of just over $4 billion.

The state of the US Electric vehicle industry in six graphs

Gas-vs-electric-cost-gallon

Electric cars continue to sell well in spite of lower gas prices. Why? Because it is still an order of magnitude less expensive to fill up an electric vehicle. And that’s if you pay for your electricity rather than get it from solar panels or free EV chargers. I expect Tesla’s Model X launch, the rise of solar panels and continuing education of car buyers to accelerate this trend for the second half of 2015. Five more graphs below:

Many of Tesla’s new battery announcement details hidden in plain site

Tesla is going to make a home battery announcement on April 30th. It will be a big deal. But it isn’t hard to find some of the details on the batteries Tesla is going to offer. Analysts, like above^ are claiming to have “secret info” on the announcement: Tesla secretly tested its battery solution with 300 customers.

But that info and much more is available on Solar City’s website. In fact, Tesla’s Home Batteries including pictures and lots of details are all  hidden in plain sight:

Tesla-battery

Tesla also gave plenty of details on their earnings call in February where Musk talked about releasing a consumer battery project:

Yes, we’re going to do — we’re going to unveil some of the Tesla home battery consumer battery that will be for you using and people’s houses or businesses, fairly soon. We have to design and it should start going into production probably about six months or so. We’ll probably got to wait to have sort of product availing it’s probably in the next month or two. It’s really great. I’m really excited about it.

If you’ve talked to Solar City, they may have provided you with the specs of Tesla’s prototype battery:

Tesla-home-battery

Tesla will certainly announce some new innovations that perhaps differentiate them from other batteries. Being able to Supercharge your Model S at home would be nice. Perhaps a Webb/App controller with some novel uses would be good.

I’d like to see it compared against home generators which cost a lot more, even before considering the savings against time of use metering in power. We’ll be on hand on the 30th to see what is on offer.
