Elon Musk aims to unveil Tesla solar power roof next month

Robert Ferris for CNBC:  Elon Musk tweeted on Thursday that he hopes to unveil a Tesla/SolarCity solar roof with a new integrated battery pack and Tesla car charger on Oct. 28.

 

Musk first began teasing the next generation Powerwall at an event for Tesla owners in Paris earlier this year, according to Electrek. At the time, he had said the company would roll out the new battery in "July or August."

SolarCity's merger with Tesla has aroused skepticism and even ire from some investors and analysts, even after Musk outlined his reasons for combining the two companies in his second installment of his "Master Plan" in late July.  Cont'd...

Tesla Wins Large Contract with Utility for Energy Storage

Jon LeSage for HybridCars:  Tesla’s energy storage division just won a very large contract with a major California utility to stabilize power outages.

While the acquisition cost hasn’t been announced, Tesla Energy will supply 20 megawatts of energy storage to Southern California Edison – enough to power about 2,500 homes for a full day. It’s part of SCE’s efforts to prevent blackouts by fossil-fuel electricity generation with lithium-ion batteries. Investment in Tesla’s product, called Powerpacks, is thought to be worth tens of millions of dollars, and is expected to be operational by the end of this year.

The deal ties into Tesla’s plans to broaden its base beyond manufacturing and selling electric cars, similar to its recent investment in SolarCity. It also signifies advancements being made in energy storage, which is reaching a much faster pace – months instead of years, according to an analyst.  Cont'd...

Berkeley Lab Study
Continued Reductions in Wind Energy Costs

Experts anticipate cost reductions of 24%-30% by 2030 and 35%-41% by 2050, under a median or 'best guess' scenario, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements

Solar on Houses Needed for 2020 Target

In the last ten years, the installed global solar energy capacity has multiplied nearly 50 times. The cost of purchasing and installing a solar panel has decreased by 80 percent in five years and is still falling. The comparable cost of electricity generation has made solar energy the cheapest energy source today, from being the most expensive only six years ago. This is truly a green revolution.

Think Wind Power Is Cheap Now? Wait Until 2030

Katherine Tweed for GreenTechMedia:  In many parts of the world, wind power is cheap. That is particularly true in the U.S., where onshore wind already rivals the cost of natural gas in some regions.

But wind power will likely get even cheaper, according to new research from Lawrence Berkeley National Laboratory published in Nature Energy, with contributions from the National Renewable Energy Laboratory, University of Massachusetts, and participants in the International Energy Agency Wind Technology Collaboration Program.

The study surveyed more than 160 wind experts across the globe. Many had deep expertise in very specific regions, but the overall findings were similar: The cost of wind will continue to come down through 2030.

There are significant variations in the current costs for wind by region, but researchers "found a considerable amount of agreement” in overall reductions as a percentage of that total cost, said lead author Ryan Wiser, a senior scientist at Berkeley Lab.  Cont'd...

China's Solar Panel Glut Undermines Its Agreement with the EU

By Reuters:  “We fear a second wave of bankruptcies,” said the head of an association of EU solar producers.  A sharp increase in solar power production in China and a sharp fall in domestic demand have sparked a sudden surge of cut-price exports, undermining a China-EU agreement to limit damage to European producers.

China produced 27 gigawatts (GW) of solar photovoltaic (PV) modules in the first half of 2016, an increase of 37.8 percent and installed 20 GW of new solar power capacity in the same period, three times as much as the same period a year ago.

However, demand has since tailed off. Solar projects operational since July face a reduced price paid by grid operators for their power.   Cont'd...

Silicon Carbide (SiC) Inverter Technology Increases Efficiency to 99%

The efficiency gain equals to approximately $2.5M additional energy being produced over a 100MW power plant's lifetime, on average at the global level.

New technology puts solar power to work all night long

ScienceDaily:  Energy storage is crucial for taking full advantage of solar power, which otherwise suffers interruptions from cloudy skies and nightfall. In the past few years, concentrating solar power plants have begun producing additional electricity at night and during peak demand periods by using stored heat energy to propel a steam turbine.

Current thermal energy storage systems rely on materials that store less energy per kilogram, requiring more material at a greater cost to meet energy storage requirements.

Now, researchers at the U.S. Department of Energy's (DOE's) Argonne National Laboratory have designed an inexpensive thermal energy storage system that will be significantly smaller and perform more than 20 times better than current thermal systems.  Cont'd...

Alternative Energy Project Financing

If storage costs can demonstrate price reductions comparable to what we've experienced with wind and solar, storage will be a big part of the story.

Is solar power in nuclear disaster exclusion zones advisable?

ARNOLD GUNDERSEN for Bulletin of the Atomic Scientists:  My own experience near solar arrays in Fukushima Prefecture indicates that the problems of building and maintaining solar installations in a contaminated nuclear wasteland are over-simplified, and worse, totally ignored. One of the greatest burdens of maintaining operating atomic reactors is the cost of working in a Radiologically Controlled Area. (The Lawrence Berkeley National Laboratory defines a Radiologically Controlled Area as: “Any area to which access is managed to protect individuals from exposure to radiation or radioactive materials. Individuals who enter Controlled Areas without entering Radiological Areas are not expected to receive a total effective dose equivalent of more than 0.1 rem (0.001 Sievert) in a year.”) Each nuclear power plant operates with specific instructions and constraints, with Radiation Work Permits tailored for each specific maintenance activity. Because special clothing, special respiratory equipment, and special radiation monitoring equipment are routinely required to perform even minimum maintenance activities inside a nuclear power plant, every activity takes longer, costs more, and requires more people inside each reactor than necessary in any other industrial setting.

Consequently, the question becomes: Does building solar panels on land contaminated with nuclear waste resemble work in a normal industrial setting, or is it more similar to work inside a radiologically contaminated atomic reactor—at significantly higher cost?  Full Article:

Is Rent-to-Own Solar Power the Answer?

Jason Overdorf for SMITHSONIAN.COM:  For a little more than a year, the family has been supplementing the sporadic electricity the village gets from the grid with solar energy, thanks to a new pay-as-you-go business model pioneered by Canadian entrepreneur Paul Needham and his company, Simpa Networks. Call it “rent-to-own solar.”

Needham is a serial tech entrepreneur whose online advertising company BidClix made its way into the portfolio of Microsoft. As a doctoral student in economics at Cambridge, he was obsessed with the reasons customers will shell out for certain products and not others. One of the questions that always bugged him was, “Why don’t I own solar panels?” The reason, he determined, was the high up-front costs.

Imagine if mobile phone service was sold like solar energy. From an operator’s perspective, it would have made great sense to try to sell customers 10 years of phone calls in advance, so as to quickly earn back the money invested in building cell towers. But the person who suggested such a strategy would have been fired immediately, Needham says.

“You want to charge people for what they value, not the technology that’s providing it,” he says in a telephone interview.  Cont'd...
