New Virginia Law Expands Solar Energy Development Authority to Include Energy Storage
   
May 9, 2017

By Renewable Energy World Editors     solar
 
Virginia Gov. Terry McAuliffe yesterday signed a bill authorizing the expansion of the state’s Solar Energy Development Authority to include energy storage.

The legislation is part of a series of bills signed by McAuliffe that promote wind, solar and energy storage technologies.

SB 1258, introduced by Sen. Adam Ebbin, expands the purpose of the new Solar Energy and Battery Storage Development Authority to include positioning the state as a leader in research, development, commercialization, manufacturing, and deployment of energy storage technology.

The powers of the authority are expanded to include

•Promoting collaborative efforts among Virginia's public and private institutions of higher education in research, development, and commercialization efforts related to energy storage,

•Monitoring relevant developments nationally and globally,

•Identifying and working with the state’s industries and nonprofit partners.

In addition, the measure expands the size of the authority 11 to 15 members.

“Today, I am honored to sign these bills into law, furthering the great work we’re doing to support and promote the clean energy sector across the Commonwealth,” McAuliffe said at the bill signing ceremony, according to the governor’s office. “It is clear that Virginia is moving in the right direction, especially with the recent announcement of record growth in our solar industry, but there is still work to do.  Together, with our partners in the General Assembly and the private sector, I will continue to implement policies that bolster the entire clean energy industry in the Commonwealth.”
 
The governor’s office said that other bills pertaining to renewables that were signed by McAuliffe yesterday include:

•SB 1393, which creates a path for the development of community solar programs in the service territories of Appalachian Power Company (ApCo), Dominion, and the Electric Cooperatives.  Each utility will develop its own territory-specific program that allows citizens and businesses the ability to “subscribe” to receive electricity generated by a small centrally-located solar generation system.

•SB 1394 and HB 2303, which are identical bills, create a Small Agricultural Generators Program — a new framework for the generation of renewable energy at agricultural facilities and how that energy can be sold to utilities.

•SB 1395 increases the allowable maximum size of renewable projects to be eligible to be permitted through the state’s Permit by Rule (PBR) process from 100 MW to 125 MW.  These projects are exempt from environmental review and permitting by the State Corporation Commission. SB 1395 also exempts projects that are being built for use by a single customer of a utility from having to apply for and receive a Certificate of Public Convenience and Necessity from the SCC.

Seraphim Solar Increases Module Production Capacity to 360 MW To Meet Growing PV Demand  
   

May 10, 2017

By Renewable Energy World Editors
 
US-based solar PV module manufacturer, Seraphim Solar , announced last month that it is on target for its planned Phase 2 expansion, which would add 200 MW of manufacturing capacity to its existing 160-MW facility.

In addition, the company said that its high-efficiency, 60-cell solar modules, designed for the residential distributed generation market, are available for purchase in addition to its 72-cell module offering.

The company’s rapid growth rate significantly contributes to the local and national economy, and continues to provide more jobs for Americans, said Seraphim. The company is partnered with the city of Jackson, Mississippi to recruit employees and local companies.

Seraphim Solar’s “Made in the USA” solar modules are expected to meet the strong residential and commercial demand for solar energy. Seraphim said that it is consistently recognized within the highest rankings of the most trusted and most stringent testing organizations in the industry, and is the first module manufacturer to pass TÜV SÜD’s ‘Thresher' test, which was co-developed by the US Department of Energy and the National Renewable Energy Laboratory to measure true long-term performance and safety.

The solar energy industry has a strong outlook for 2017. According to Mercom Capital’s most recent industry overview, Total corporate funding (including venture capital funding, public market and debt financing) into the solar sector in Q1 2017 doubled with $3.2 billion compared to $1.6 billion in Q4 2016. Year-over-year funding in Q1 2017 was about 15 percent higher compared to the $2.8 billion raised in Q1 2016.
 
In addition to large-scale solar, electric generating capacity from small-scale solar systems is increasing. In 2016, the U.S. Energy Information Administration (EIA) estimates that the U.S. added 3.4 GW of small-scale solar generating capacity across all three end-use sectors, ending the year with more than 13.1 GW of installed capacity. According to EIA estimates, California, New Jersey, and Massachusetts had the most small-scale solar capacity with 5.4 GW, 1.3 GW, and 1 GW, respectively.

Arizona Utility Buys Solar Power at ‘Historically Low Price’
 

May 25, 2017 By Renewable Energy World Editors
         
Arizona utility Tucson Electric Power (TEP) said this week that it will buy solar energy at a historically low price from a new local system large enough to power 21,000 homes.

The 100-MW solar array and an accompanying 30-MW energy storage system are expected to be in service by the end of 2019. TEP said that, excluding the cost of storage, it will buy the system’s output for 20 years for less than $0.03/kWh — less than half as much as it agreed to pay under similar contracts in recent years.

“This new local system combines cost-effective energy production with cutting edge energy storage, helping us provide sustainable, reliable and affordable service to all of our customers for decades to come,” Carmine Tilghman, senior director of energy supply and renewable energy for TEP, said in a May 22 statement.

An affiliate of NextEra Energy Resources will build, own and operate the system on a site owned by the City of Tucson located inside TEP’s service territory south of the metropolitan area.

NextEra also will build and operate a long-duration battery storage system on the site that will help integrate renewable energy resources into TEP’s local energy grid. The storage system will be capable of providing up to 120 MWh of power.

China Activates World’s Largest Floating Solar Power Plant

May 26th, 2017 by Steve Hanley

SNIPPET:

The panels help to conserve precious freshwater supplies by lowering the amount of evaporation into the surrounding atmosphere  . In return, the water keeps ambient temperatures around the solar panels lower, which helps boost their efficiency and limit long-term heat-induced degradation.

The most interesting thing about the floating solar power plant in Huainan, however, is that the lake supporting it was created by rain after the surrounding land collapsed in a process known as subsidence following intensive coal mining operations over a period of years. Anhui province is rich in coal reserves and has been the source of much of the coal used to power the Chinese economy.

“Sungrow supplied the plant’s central inverter unit, which transforms direct current from the solar panels into an alternating current for delivery to the local power grid,” I Drop News reports. “The manufacturer also supplied a customized combiner box that aggregates power from multiple solar panel arrays and sends it to the central inverter. The combiner box has been specifically designed for floating PV plants and can operate in environments with high humidity and salt spray.

https://cleantechnica.com/2017/05/26/china-activates-worlds-largest-floating-solar-power-plant/

Agelbert Note: Well, will wonders never cease?  ;D Renewable Energy actually benefited from intensive coal mining caused subsidence.  :D

Trina IBC Solar Cell Record 'Significant'

May 26, 2017

By Charles Thurston  Freelance Writer

 The 15-MW Sunshine Coast Solar Farm in Valdora powered by Trina Solar panels
         
The recent announcement by Trina Solar that it had reached a new solar conversion efficiency record of 24.13 percent in a Changzhou, China laboratory for an interdigitated back contact (IBC) mono-crystalline silicon cell, is a “significant achievement,” according to a U.S. laboratory analyst.

Quote
“The efficiency is significant given the size of the cell at six inches,” says Abasifreke Ebong, a professor in the Department of Electrical & Computer Engineering at the University of North Carolina at Charlotte.

The 156 millimeter (mm) ×156 mm solar cell reached a total-area efficiency of 24.13 percent as independently measured by the Japan Electrical Safety & Environment Technology Laboratories (JET).

Trina said that the n-type mono-crystalline silicon solar cell was fabricated on a large-sized phosphorous-doped Cz (cubic zirconia) Silicon substrate with a low-cost industrial IBC process, featuring conventional tube doping technologies and fully screen-printed metallization.

Ebong notes that “the process of fabricating the cell is not outlined, which I believe is still the expensive lithography technology. Also, it is a laboratory demonstration which may take another year or so to implement in production.” The Energy Production and Infrastructure Center (EPIC) at the Charlotte Research Institute campus of UNC Charlotte, is a state-of-the-art research center that conducts applied research.
The technical description of the cell test includes the following: “The champion cell presents the following characteristics: an open-circuit voltage Voc (overclocking) of 702.7mV (millivolt), a short-circuit current density Jsc (short-circuit current density abbreviation) of 42.1 mA/cm2 (milliamps per square centimeter) and a fill factor (FF) of 81.47 percent,” Trina reported.

In April 2016, Trina Solar announced an improved industrial low-cost IBC solar cell with a total-area efficiency of 23.5 percent. Total-area efficiencies are always lower than aperture-efficiencies, due to efficiency losses related to the edges of the cells and electrical contact areas.   
 
In February 2014, Trina Solar and the Australian National University (ANU) jointly announced a world record aperture efficiency of 24.37 percent for a laboratory-scale 4.0 cm2 IBC solar cell, fabricated on a Float Zone (FZ) n-type substrate and using photolithography patterning. In December 2014, Trina Solar announced a 22.94 percent total-area efficiency for an industrial version, large size (156mm x 156mm, 6" substrate) IBC solar cell, the company noted.

"Over the last few years, our R&D team has managed to continuously improve the efficiency of our n-type IBC solar cells, pushing the limits and surpassing our previous records, and approaching very closely to the performance of our best small-area laboratory cell developed in collaboration with ANU three years ago,” said Dr. Pierre Verlinden, Vice-President and Chief Scientist of Trina Solar.

"IBC solar cells are one of the most efficient silicon solar cells available today and are particularly suitable for applications for which the requirement of a high power density is more important than LCOE (Levelized Cost of Electricity). We are very happy to announce today that our industrial large area IBC cell has reached almost the same level of performance as the small-area laboratory cell made three years ago with a photolithography process,” Verlinden added.

Nevada Reinstates Net Metering

Nevada has reinstated a key rooftop solar policy that advocates say will revive the solar industry in the state. Republican Governor Brian Sandoval signed a bill that reinstates net metering yesterday at the Tesla warehouse in Las Vegas. After Nevada did away with net metering in late 2015, the state saw a 32 percent decline in solar installation jobs. 

Solar giants Tesla, Sunrun and Vivint Solar have said they will return to Nevada and expand operations in light of the new policy

"You do not Drill for solar. You do not Mine for solar. You MANUFACTURE SOLAR; THAT CREATES JOBS!"   


Solar power is already saving lives in the US. Here's how 

Updated by David Roberts@drvoxdavid@vox.com  Jul 2, 2017, 9:22am EDT

SNIPPET:


And finally, these are just benefits — no account of the costs of a large-scale shift to solar, which are real.

Okay, with all that said, on to the results! 

1) Benefits of existing solar

Here are the annual benefits of the solar installed in the US to date:


benefits of solar (DOE)

For the chart averse, that's:

Annual reduction of 17 million metric tons of CO2, which is, based on the central estimate of the social cost of carbon, "equivalent to an annual global benefit of $700 million."

Annual reductions of "10,000, 10,300, and 1,200 metric tons of SO2, NOx, and PM2.5, respectively ... which provide annual domestic air quality benefits of $890 million."

Annual water "withdrawal and consumption savings of 294 billion gallons (0.8% of power sector total) and 7.6 billion gallons (0.5% or power sector total), respectively, with much of those savings located in drought-impacted California."

It's worth keeping in mind that the somewhat clinical phrase "domestic air quality benefits" is another way of describing fewer kids having asthma attacks, fewer adults missing workdays, and fewer people dying of respiratory and circulatory ailments.

It's also worth keeping in mind that none of these social benefits are priced into the cost of solar; it is not compensated for its "positive externalities." If it were, it would knock almost 5 cents a kilowatt-hour off the price, which would mean the Sunshot cost target was already achieved.


Agelbert NOTE: Give the subsidies to Renewable energy Technologies, not polluters that are killing us! 


2) Benefits of solar at Sunshot target levels

Here are the benefits of hitting the Sunshot solar penetration targets (again, as compared with a scenario in which no new solar is built):

benefits of sunshot solar (DOE)

For the chart-averse, that's:

A cumulative savings of 10 percent of power sector emissions from 2015 to 2050, which represents a $259 billion global climate benefit.

Reductions in emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and fine particulate matter (PM2.5) sufficient to secure a cumulative $167 billion worth of avoided health and environmental damages.

Reduction of power sector water withdrawals by 46 trillion gallons (4 percent of total sector withdrawals) and water consumption by 5 trillion gallons (9 percent of total sector consumption). Importantly, water savings are concentrated in arid states.


The climate and pollution benefits together amount to $400 billion between 2015 and 2050, measured in present-value terms and using central estimates.

3) Where the benefits are concentrated

Finally, it's interesting to note that the local benefits of solar vary significantly based on what kind of power it displaces. In places where it pushes aside coal (as opposed to natural gas or even wind), benefits are highest.

I already mentioned that the water-saving benefits of solar are overwhelmingly concentrated in arid California. Here's where the local air quality benefits are concentrated:

solar air quality benefits (DOE)

On the left are the monetized air quality benefits. On the right are the equivalent changes in solar prices if the benefits were included in costs. Looks like the heavily populated Northeastern corridor could use more solar!

Panda-Shaped Solar Power Farm Providing Clean Energy To China
July 18th, 2017 by Steve Hanley


SNIPPET:

China Merchants New Energy Group is one of the largest clean energy companies in China. It is deep into a solar power project that will eventually cover more than 1,500 acres with solar panels. The first phase of construction was completed on June 30 — a 248 acre solar farm that looks like a a giant panda from the air. When complete, several panda-shaped areas will populate the Chinese countryside.

Elon Musk Tells Governors About Solar Power & US Gigafactories

July 19th, 2017 by Steve Hanley

SNIPPET:

Quote
Solar In The US

Elon Musk at NGA“If you wanted to power the entire U.S. with solar panels, it would take a fairly small corner of Nevada or Texas or Utah. You only need about 100 miles by 100 miles of solar panels to power the entire United States.”

Of course, some grid storage capability would need to be included. Musk has an answer for that, too. “The batteries you need to store the energy, to make sure you have 24/7 power, is 1 mile by 1 mile. One square mile. That’s it.

Why is Musk so high on solar? Because it’s there, it’s free, and it reliable. “People talk about fusion and all that, but the sun is a giant fusion reactor in the sky. It’s really reliable.  

It comes up every day. If it doesn’t, we’ve got bigger problems,” he joked.

At $200/sqmeter that is 4 trillion for the PV, at $500/KWHr of battery that is 8 trillion for the battery, at a billion dollars per 200km of transmission of 2GW and 2.5 trillion for transmission lines for a grand total of 12.5 trillion dollars. With an average net weighted life time of 30 years (shorter for battery and longer for transmission lines) and 3% interest rate we get 750 billion dollars per year not including local distribution. Or about $7000 per worker per year. This does not include transport fuels, home heating, industrial energy use. About a factor of three for all that give $21000 per worker per year for US energy from solar.

 


Have you entirely lost your mind? Listen, Einstein, before you start crunching your incredibly inaccurate numbers for Renewable Energy solar and battery backup powered US grid, I suggest you LOOK INTO the MTBF of EVERY internal combustion engine out there NOW that moves people, things and provides power for and power backup for the grid and hospitals.

After you find out the GARGATUAN amount of money that costs NOW to operate, maintain and replace those polluting PIGS (never mind the HORRENDOUS Social Costs of Carbon that SHORT TERM PROFIT STUPIDITY is DUMPING on we-the-people that INCREASES MASSIVELY our health care cost, LOWERS work attendance (i.e. PRODUCTIVITY) and generally makes it MORE COSTLY to grow crops), THEN we can talk about comparing numbers.

There is only one thing I can say about your ridiculous number mumbo jumbo, straw grasping attempt to deride the Renewable Energy solution (SEE BELOW):


Unlike Edpell  , who can only sound the Death knell,
objective people know better.  

Agelbert NOTE: Edpell, DO NOT comment unless, and until, you have completely read the following post (see below). I will delete your post if you do. I will delete your post if you try to pump more unsubstantiated disinformation bullshit on this thread. Have a nice day, Fossil Fuel defending TROLL.


100% Clean, Renewable Energy Is Possible    — Setting The Record Straight

July 22nd, 2017 by Karl Burkart


SNIPPET:

Since 2009, Mark Jacobson, Professor of Civil and Environmental Engineering at Stanford University and Senior Fellow at the Woods Institute for the Environment and Precourt Institute for Energy, and more than 85 coauthors have written a series of peer-reviewed journal articles evaluating the scientific, engineering, and economic potential of transitioning the world’s energy infrastructures to 100% clean, renewable wind, water, and solar (WWS) power for all purposes by 2050, namely electricity, transportation, heating, cooling, and industrial energy uses.

These papers have helped to shift the global conversation around the possibility of completely decarbonizing the world’s energy sector through renewables. They have helped to motivate a wave of 100% renewable energy commitments by over 100 cities and subnational governments, including 35 cities in North America, 100 large international companies, and 48 countries. California, the world’s 6th largest economy, just announced its 100% by 2045 renewable target and proposed U.S. House Resolution HR540, U.S. Senate Resolution SR 632, and U.S. Senate Bill S.987 calling for the United States to go to 100% clean, renewable energy by 2050.
