The World's Largest Solar Plant Is Now Online in India

Avery Thompson for Popular Mechanics:  The world's largest solar power plant has just been completed in Kamuthi, in Tamil Nadu, India. The new plant adds 648 MW to the country's generating capacity.

The Kamuthi Solar Power Project takes the title of world's largest solar plant from the Topaz Solar Farm in California, which was completed two years ago and has a capacity of 550 MW.

The Kamuthi Solar Power Project was built in only 8 months, and cost $679 million to complete. It contains 2.5 million individual solar panels, covers an area of almost 4 square miles, and is expected to power 150,000 homes.  Cont'd...

Tesla powers a whole island with solar to show off its energy chops

James Vincent for The Verge:  Tesla completed its $2.6 billion acquisition of SolarCity this week, and, to celebrate, the company has announced a major solar energy project: wiring up the whole island of Ta’u in American Samoa. Previously, the island ran on diesel generators, but over the past year Tesla has installed a microgrid of solar energy panels and batteries that will supply "nearly 100 percent" of power needs for Ta’u’s 600 residents.

The project seems intended to show off the potential benefits of the SolarCity acquisition, with Ta’u’s microgrid comprised of 5,328 solar panels from SolarCity and Tesla, along with 60 Tesla Powerpacks batteries for storage. But buying SolarCity remains a risky move for Tesla, with the purchase including billions of dollars of debt for a company that's far from profitable (SolarCity spends $6 for every $1 it makes in sales). Nevertheless, Tesla CEO Elon Musk describes the acquisition as "blindingly obvious" — a necessary step in his so-called "Master Plan" to integrate clean energy generation and storage.  Cont'd...

Integrated Energy Systems

Opportunities for solar installers to offer storage as an integral part of their solutions are opening up everywhere, from mitigating the impact of power outages, the increase in distributed renewable generation at times of low use, the rising costs of base and peak power and the trend of some states to reduce or eliminate net metering programs.

Power to the people: Solar panel sales to soon surpass leasing

Lucas Mearian for ComputerWorld:  Direct ownership of solar power panels will overtake third-party ownership next year as more consumers are choosing to buy, rather than lease, their panels.

According to GTM Research's latest report, U.S. Residential Solar Financing 2016-2021, 55% of all U.S. residential solar capacity installed in 2017 will be purchased by customers paying either in cash, or through a solar loan financing arrangement; that number is expected to grow to 73% of all solar systems installed in 2021.  Cont'd...

Want to boost wind and solar power? Bring them together

Ben Jervey for GreenBiz:  What’s keeping solar and wind power from fully taking over the electric grid? For starters, the sun only shines during the day. Wind blows intermittently, is seasonally variable, and is not always blowing when the energy is needed.

But what if solar and wind work together?  "Wind resource tends to complement solar resource," said Sarah Kurtz of the U.S. Department of Energy’s National Renewable Energy Laboratory. "Here in Colorado, for instance, the windiest time is during the winter and spring months. In winter, we don’t have as much sunshine, but we tend to get more wind and stronger wind."

A handful of enterprising renewable energy developers are exploring how solar and wind might better work together, developing hybrid solar-wind projects to take advantage of the power-generating strengths of each — with the two technologies in tandem serving as a better replacement for climate-warming fossil fuels than either could be alone.  Cont'd...

Economics Trumps Policy: Even President Trump Cannot Stop the Renewable Energy Juggernaut

The renewable and energy efficiency industries have created over 2.5 million jobs in the United States. Solar now employs more Americans than than oil, natural gas and coal combined. The nation's fastest growing occupation is, believe it or not, the wind turbine technician; which is still projected to grow 108% in the next 7 years.

Renewed Interest from Traditional Investors in Renewable Energy

Renewables have now reached such a critical mass, utilities can no longer ignore them as a way to augment their capabilities in producing power cheaper, smarter, better. At this point, the tide has turned for utilities and there is no going back.

Solar Power Turns Water and Carbon Dioxide Into Fuel

Seeker:  Finish researchers are building a demonstration power plant that would use solar-generated electricity, water and carbon dioxide extracted from the atmosphere to create gas and liquid fuels.

The Lappeenranta University of Technology and VTT Technical Research Centre are working together on the SOLETAIR project, which is being built on the university campus and is scheduled for completion in 2017. Germany's Karlsruhe Institute of Technology also is a player in the project.  The project involves several different innovations. VTT will design equipment that will capture CO2 from the air and store it, while Lappeenranta researchers will build a device to produce hydrogen from water via electrolysis. Karlsruhe has developed a a microstructured, chemical reactor to convert the hydrogen produced from solar power together with carbon dioxide into liquid fuels, according to a press release. The reactor will be built by INERATEC, a spinoff company created by Karlsruhe.  Cont'd...

Solar Power Meets Electric Vehicle Atop a VW Microbus

Brett Belan, Apparent Energy for MotherEarth News:  The time is here for solar power to make its way to our vehicles. The state-of-the-art panels pose no weight limitation. At 6 pounds per 150 watts, thin flexible solar panels will weigh 600 pounds but give you 15 kilowatts! This is enough to directly drive from the sun.

However, the surface area is a limitation, because that much solar would require 10 feet around the vehicle on all sides. The solution, ironically, is a mechanical engineering question of how to accordion-style fold these panels to conveniently open them for charging while the vehicle is at a standstill.  Cont'd...

Solar power proponents hopeful Trump sees benefit of growing industry

Ivan Penn and Rob Nikolewski for The LA Times:  Longtime solar executive Barry Cinnamon got up Wednesday wondering what a Donald Trump administration will mean for his industry.

“I woke up this morning and walked to my car and took a picture of the sun coming up, and it did indeed come up,” said Cinnamon, president of Cinnamon Solar, one of the highest-profile solar companies in Silicon Valley.

Candidate Trump said a lot of things that heartened conventional oil and natural gas producers and worried the renewable energy business, which is growing fast but is still a tiny part of the energy landscape.  Cont'd...
