The video below is about a multi-tasking solar module system, R-Volt, by a French company SystoviM. Ludovic Baudry explains this clean and conserving solar module system during Intersolar North America 2015, at Moscone Center of San Francisco, CA, in July of 2015. As indicated in the above diagram, there is an extra layer of air gap that would allow forced air through to utilize the heat generated from the solar cells under the sun to heat up the house while boosting the solar cell efficiency by reducing the heat on the solar cells (henceforth, aerovoltaic). This rather smart and efficient design of generating electricity-heating up the house-boosting solar cell efficiency simultaneously would be particularly welcomed in colder climate regions.

Intersolar North America 2015, In San Francisco, With Intention

Share

Dear Friends, Visitors/Viewers/Readers,

Permanent art installations from Janet Echelman, Kendall Buster, Norie Sato, Charles Sowers, and Walter Kitundu of San Francisco (SFO) international terminal in Terminal 2, formerly known as the "Central Terminal" replaced Rotunda A as SFO's international terminal in 1983.

Permanent art installations from Janet Echelman, Kendall Buster, Norie Sato, Charles Sowers, and Walter Kitundu of San Francisco (SFO) international terminal in Terminal 2, formerly known as the “Central Terminal” replaced Rotunda A as SFO’s international terminal in 1983. (photographed by sunisthefuture-Susan Sun Nunamaker)

(Please click on red links & note magenta)

Of all the photos I took during the trip to Intersolar North America at San Francisco, CA, I find this one (above) truly reflects the spirit of San Francisco. Take a look at how this piece of sculpture by Janet Echelman is described in wikipedia:

Echelman transforms the terminal with fictional nature that subtly engages viewers with real and imagined natural forces. Her sculpture installation cuts three round skylights into the ceiling, from which descend delicate layers of translucent colored netting to create three voluptuous volumetric forms. A series of shaded outlines below are embedded into the terrazzo floor, reflecting the precise shadows that would occur on the summer solstice if the sun could penetrate through the roof. During the day, sun streams through the skylights to cast real shadows that interplay with the fictional shadows in the floor. At night, the artist’s program of colored lighting makes the sculpture glow from indigo to purple, magenta to red-orange. Computer-programmed mechanized air-flow animates the fluidly-moving sculpture at different intervals throughout the day, as if the wind could magically flow through solid walls.

The artist achieved the sculpture’s physical presence by braiding fibers and knotting twine into sculptural netting suspended from powder-coated steel armatures. Despite their large scale, more than 120 feet in circumference for a single form, her sculpture is experienced as ephemeral and weightless. Visually, the sculpture evokes the contours and colors of cloud formations over the Bay and hints at the silhouette of the Golden Gate Bridge. Aesthetically, the sculpture looks both backwards and forwards, drawing its color from the heyday of psychedelic music, the Summer of Love, and San Francisco’s prominence in the beat poetry movement, while also referencing the contemporary bay area as a hub of innovation and interconnectivity for the world of technology.

There is definite intention behind how and why San Francisco is such a hub of innovation and interconnectivity for the world of technology. I have personally observed, on more than one occasion, how San Francisco network had actively gathered/netted in talents from other parts of the USA and good part of the planet earth. On this particular trip, more than ever, I have gained so much information, hope, and optimism for the future of solar industry and technology during Intersolar North America 2015, that I can truly appreciate such netting mechanism radiated from this little area of approximately 46 sq mi. That is why the artist/sculptor Janet Echelman from Tampa, FL , has her sculpture displayed in San Francisco International airport terminal 2 instead of in Tampa, FL.   In the short 3-4 days of Intersolar North America 2015, more than ever before, I can see the future certainty of Solar Tsunami. Coming from a background of mathematics and engineering (civil and mechanical), I’ve gained much of my understanding for the power/energy industry by having an in-house (hubby) technical advisor with electrical engineering background. What seemed to me, intuitively, the natural solution for Energy-Pollution-Economy-Climate Change-International Conflicts during my freshman year in college more than three decades ago, the Solar Energy, will finally be in the main stream!

There will be a series of posts and videos from Intersolar North America 2015 during the remaining of this week and good part of the next week demonstrating how Solar Energy will soon be in the main stream. World wide, we have Germany to be thankful for. USA wide, we have CA and San Francisco to be thankful for.

InterSolar North America Opening Ceremony

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

I really need to share this “Standing Ovation at the InterSolar North America Open Ceremony” with you all, taking place in July of 2014, at Moscone Center of San Francisco, CA.:


 

California Gov. Edmund G. Brown Jr. was met with a standing ovation as he delivered the keynote remarks at Intersolar North America’s Opening Ceremony 2014. Following the Governor’s remarks, San Francisco’s Mayor Edwin M. Lee took the stage. New York State Senator Kevin S. Parker similarly championed local policies that have grown the solar energy industry significantly in New York. Franz Untersteller, minister of the environment, climate protection and the energy sector, Germany, discussed the major policy incentives implemented in Germany that have played a key role boosting the solar industry. Finally, CALSEIA’s executive director Bernadette Del Chiaro concluded the session with a discussion of California’s solar policies and an inspirational call to action, asking the audience to help quadruple the solar industry in the next six years.

It is important to point out/remind ourselves that:

1. There is much more solar that needs to be installed in the decades to come!

2. There is much more needing to be done. We’ve not yet met the turning point to Sustainability.

3.  The cost of PV modules has dropped 80% in the last five years.

4.  Solar Industry employs more than 142,000 people in USA (more than 50,000 in CA).

5.  We can look to and utilize much of the lessons learned from Germany.

6.  Solar is desperately NEEDED now, especially in light of climate change.

7.  16.5% of the electricity supply of CA on any given day is from Solar (without including the 2 GW on rooftops).

8.  CA Solar Industry now employs more people than the three investor-owned utility companies combined.

So, let those of us in the rest of the 49 states also align ourselves with this tremendous task of transitioning into the Renewable/Solar Energy Future!

Perovskite Solar Cell Technology of Oxford PV, The Potential Game-Changer

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

At InterSolar North America 2014 in San Francisco, CA, I came across a potentially game-changing technology that holds much promise for low cost solar power in the future.  This technology, the perovskite thin-film solar cells, is currently being developed by Oxford PV (a spin-out from the University of Oxford in 2009-2010 to commercialize this technology, which has exclusively licensed the intellectual property developed by Professor Henry Snaith and his team of 20 scientists). The perovskite thin-film solar cells can be directly printed/sprayed onto glass to produce a semi-transparent colored coating. Below is an interview with the Chief Technology Officer, Dr. Christopher Case, of Oxford PV:


The apparent enthusiasm of Dr. Case is seen in his discussion of the perovskite cell technology. One can understand the source of Dr. Case’s enthusiasm. According to Dr. Case, “the perovskite in solar application is the fastest increasing photovoltaic efficiency of any solar photovoltaic thin film material ever! In just a few years, it went from a lab efficiency of about 6% to well over 17%…the material is a very good solar absorber….bringing the material to 25% efficiency in a monolithic layer and 30%+ in a perovskite tandem layer….potentially the future replacement for silicon.” This perovskite solar cell technology is optimized to drive a paradigm shift in the aesthetics, performance, and cost of BIPV (Building Integrated Photovoltaic) systems, potentially bringing low cost electricity to the solar market much sooner than predicted. It is no wonder the highly respected international journal, Nature, has named Dr. Henry Snaith of University of Oxford as one of the ten people who have made the most difference in science during 2013 in recognition of his work on this next generation solar power technology. Let’s also take a look at the comparison between Convetional PV vs. Oxford PV, below (provided by www.oxfordpv.com):

 

Conventional PV                                                                         Oxford PV_________________

Opaque                                                                                      Range of transparency options

Blue or Black                                                                              Palette of colors and tints

Contains scarce elements and rare earths                                  Sustainable, abundant, organic ingredients

Complex, high temperature and high vacuum manufacturing    Simple screen printing manufacturing processes

High capital cost of manufacturing                                            Low capital cost of manufacturing

Heavy panels physically attached to building                          Aesthetically attractive glazing panels integrated into the building envelope

__________________________________________________________________________________

Without using the titanium dioxide as a semiconductor, this technology results in higher levels of efficiency, much lower processing temperature, and improved cell stability. Oxford PV plans on continuing to optimize this technology’s cell efficiency and accelerate the transfer of the technology into production. Furthermore, it aims to develop the range of substrates to which the cells can be applied.

Oxford PV has a strong supporting team (such as Kevin ArthurDr. David Fyfe, Paul Vickery, etc.) With its promising future, we, the solar enthusiasts and investors alike, should keep our eyes on Oxford PV in the coming years.

Further Expansion By QBotix, Integration of Robotics Into Solar Tracking System

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

Do you remember one of our posts during 2012 about a tracking system designed by a new company called QBotix?  To refresh your/our memory, please refer to the paragraph from our previous 2012 post, below:

The recently unveiled RTS by QBotix, a new company (from Menlo Park, CA) that is bringing the power of robotics to solar energy. The Robotic Tracking System (RTS) is a comprehensive dual-axis tracking system (at a single-axis system’s cost but generates up to 15% more energy) that employs rugged, intelligent and mobile robots to dynamically operate solar power plants and maximize energy output.  By having the robot (some call it solbot) running on a track, as a monorail,  servicing up to 200 solar panels, at 40-minute intervals throughout the day, this tracking system can help the solar panels to receive a performance boost of as much as 40% over existing fixed mount systems and lowers the Levelized Cost of Electricity (LCOE) by up to 20%.  Furthermore, RTS offers fast installation and has low operation and maintenance costs, and is compatible with all solar panels and mounting foundations.  When connecting with each panel, RTS adjusts the angle of the panel and collects data about the panel.  I can see the potential of a self-cleaning RTS/solbot that may be programmed to conserve/minimize the water use in cleaning all solar panels.  Wouldn’t that be great?!  Apparently, RTS also has a certified IP-65, meaning it is impervious to dust and water.

Be sure to also take a look at our interview this year (2014), with Matt Lugar, VP of Sales and Marketing of QBotix, during InterSolar North America 2014, at Moscone Center, San Francisco, CA, below:


Much has happened to QBotix since we last interviewed  its founder and CEO Wasiq Bokhari and Director of Engineering Lalo Ruiz in 2012. Recently QBotix has announced that it has raised $12 million in Round B  financing through its venture capital partners, E.On Climate and Renewables and Iberdrola Renewables. This is in addition to having already successfully completed a $1 million U.S. Department of Energy (DOE) SunShot Initiative award project, and received the  recognition by Fast Company as one of the world’s top 10 most innovative companies in robotics. When we met QBotix in 2012, it was a design with zero installations, but now it’s gone global, with 80 MW  installations and contracts or partnerships in U.S., Europe, Latin America, Australia, Japan, and further development in Chile and South Africa. QBotix has the revolutionary, highly efficient technology that will contribute significantly to reduce the balance of system costs in solar projects. We will look forward to its continued expansion and spreading throughout our planet.

GTAT Bringing Merlin To Solar Industry

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

This is an interview with the team (Sr. Vice President/General Manager Dr. Venkatesan Murali, Sr. Director of Marketing Jeff Nestel-Patt, and Vice President of Sales Andrew Barta) from GT Advanced Technologies (GTAT) at San Francisco, CA, during InterSolar North America 2014, on July 9, 2014,overlooking the Yerba Buena Gardens on top of Moscone North. Video below:


As the global demand for solar energy continues to grow while the industry is facing downward pricing pressure, reduced subsidies, and solar trade tensions, it becomes increasingly important for PV manufacturers to achieve further cost reductions and improved cell efficiency. GTAT accomplishes this by introducing the innovative metallization & cell interconnect technology (Merlin Advanced Metallization Technology) that transforms the solar module into a less expensive, more efficient panel that is easier to install.

The Merlin Advanced Metallization Technology enables greater performance than the traditional modules by:

  1. Eliminating up to 80% of the expensive silver paste used in the traditional cells and modules, leading to cost reduction.
  2. The same screen printing equipment installed in cell line can be used to print the segmented fingers onto the cell
  3. Flexible grid that eliminates silver bus bars: a plated copper grid is attached to the segmented fingers on the top of the solar cell. The combination of segmented fingers and flexible grid makes it easier to move current off the cell. The flexible grid provides 20 paths/highways for the current to travel along rather than the three bus bars found on the traditional solar cells.
  4. Reducing shading by bus bars and increasing electrical connections on the surface of the cell  lead to increased cell efficiency and increased power output (by 3-5% compared to standard module).
  5. Improving the interconnection between cells by eliminating the need for stringing and tabbing of the old technology, providing highly flexible and durable way to connect cells while eliminating the bus bar tabs of traditional cells. Cells can therefore be connected closer together, allowing a smaller and more flexible module than the conventional module.
  6. The flexible tabs at the end of each grid solve the problem generally associated with breakage of modules during transport resulting from metal fatigue when ribbons break due to dynamic loading conditions during shipping.
  7. GTAT is almost 50% lighter than the conventional modules.
  8. Easier installation results in lower balance of system costs

(Please also refer to this video for visual demonstration: https://www.youtube.com/watch?v=hf2E_Uq3Lzw)

GTAT is already working with select customers to implement Merlin, involving custom-made copper meshes soldered on to PV cells instead of bus bars. GTAT will produce and sell customized copper meshes to customers, and expects to reach a production capacity of 100 MW annually by the end of 2014. In early 2015, it will begin to offer a wire attachment tool to customers, which will replace the tabbing stringer. Orders may be taken in last quarter of 2014, so in 2015, solar PV module makers will be able to work with this new technology to replace silver bus bars with a customizable copper mesh, reducing silver usage, increasing power output, and allowing lighter modules to be transported and installed.

GT Advanced Technologies Inc. is a global provider of polysilicon production technology and sapphire and silicon crystalline growth systems and materials for the global solar, LED, and other electronics industries and specialty markets. The company’s products and services accelerate the adoption of new advanced materials that improve performance and lower the cost of manufacturing.

Ideal Power’s 2-Port & 3-Port Hybrid Converters at InterSolar North America 2014

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

I’d like to share with you an interview at InterSolar North America 2014, in Moscone Center of San Francisco, CA on July 9, 2014. The future of the multi-billion dollar solar industry depends much on the progress in combining PV with energy storage. In this post, Sun Is The Future will present to you Ideal Power’s AWARD winning 30KW Hybrid PV Storage Converter (which is becoming the de facto industry standard to enable PV+storage integration). Ideal Power received its award on June 4th during a ceremony at InterSolar Europe in Munich, Germany, the world’s largest exhibition for the solar industry. Ideal Power’s technology stood out due to its ability to combine PV and battery systems with an efficiency level of up to 97%. It also provides modular flexibility for different applications, particularly in off-grid systems. Due to the dramatic improvement in size, weight, cost, and efficiency over conventional converters, the Hybrid Converter integrates multiple power sources (i.e. PV+storage+grid) to lower the cost of delivering grid resiliency during blackouts such as Superstorm Sandy. I can’t wait to get my hands on the 3-port Hybrid Inverter/Converter (125 lbs) that will enable us to be better prepared for future natural disasters without the dependence on the grid. Currently the 2-port converter system (100 lbs) is used for demand reduction in grid-tied system (currently used in Walgreen of  Southern CA) whereas the 3-port converter will be in one box and creates its own microgrid during power outage.

Below, is an interview with John Merritt, Director of Applications Engineering, of Ideal Power, at InterSolar North America 2014:


Ideal Power’s hybrid converter is the first 3-port product to leverage the Company’s Power Packet Switching Architecture™ (PPSA), which allows it to combine PV inverter capabilities on one DC port, bi-directional battery converter capabilities on the second DC port, and provide an AC port supporting both grid-tied and off-grid applications. It can accomplish these functions with only a modest increase in product size and weight over its established 2-port battery converter and PV inverter products and with no loss of system efficiency. Conventional technology solutions to hybrid power conversion systems combining PV and storage require multiple power conversion steps, thereby reducing efficiency, and multiple power converter units, increasing size, weight and cost. (Ideal Power press release)

 

About Ideal Power Inc.
Ideal Power Inc. (NASDAQ: IPWR) has developed a novel, patented power conversion technology called Power Packet Switching Architecture™ (PPSA). PPSA improves the size, cost, efficiency, flexibility and reliability of electronic power converters. PPSA can scale across several large and growing markets, including commercial Battery Energy Storage Systems (BESS), electrified vehicle charging, and solar photovoltaic generation. Ideal Power utilizes a capital-efficient business model to commercialize our technology through the use of contract manufacturing, product licensing, and market distribution channels. Ideal Power has won multiple grants including one from the Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) to commercialize bi-directional power switches, which are expected to improve power density by thirty percent and reduce efficiency losses by fifty percent.

CITEL TO EXHIBIT 2016-READY SPD’S AT INTERSOLAR NORTH AMERICA 2014

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links below and note magenta)

Below is the press release from one of the presenters at InterSolar North America in San Francisco, CA in July 8-10, 2014.

CITEL TO EXHIBIT 2016-READY SPD’S AT INTERSOLAR NORTH AMERICA 2014

Miramar, FL – May, 2014 – CITEL, the leader in photovoltaic surge protective devices, is excited to announce that their 2016-ready SPD’s will be featured at Intersolar North America this July. “We are excited to show the solar community our surge protective devices at Intersolar 2014.” said Patrick Coyle, VP of CITEL, “Our SPD’s have been specifically engineered to meet the protection needs of PV systems and ready for the UL updates in 2016.” CITEL continues to lead the way in the solar industry by developing innovative surge protection solutions specifically for photovoltaic applications now reaching up to 1500 vdc.

By their remote nature, Photovoltaic (PV) systems are highly exposed and vulnerable to lightning induced power surges. A PV system that is not equipped with surge protection can be severely damaged or even destroyed in the case of an over voltage such as one that would be caused by a lightning strike. Not only are the panels themselves targets for lightning, so are inverters, combiner boxes, feeder lines, structural supports, and even data lines throughout the system. The risk is so high that international standards have been written specifying the type and locations of SPD’s in a PV installation. A full surge risk assessment is an important step when installing a PV system, in order to identify any safety requirements.

Surge protective devices are essential in order to achieve the ROI that fully operating PV systems are designed to provide. SPD’s provide reassurance that the system will be protected in the lightning-prone environment in which it is placed, thus protecting the investment and avoiding costly downtime, repairs, and replacements. It is essential that anybody considering a PV installation also incorporates the protection of an SPD.

Some of CITEL’s surge protective devices that will be displayed at Intersolar North America are:
 DS60VGPV – UL Type 1 CA DC SPD’s
 DS50VGPV – UL Type 1 CA DC SPD’s
 DS50PVS – UL Type 1 CA DC SPD’s
 DS2x0S-xxDC – Type 2 DC or AC SPD’s
The DS60 and DS50 family of SPD’s are also 2016-ready. By 2016, all UL1449 3rd Edition SPD’s will be required to test and publish a short circuit current rating (SCCR) and pass the intermediate current tests in order to comply with more stringent SPD component assembly standard. The DS60 and DS50 products also have the option to feature CITEL’s patented VG Technology.
