During this 4-part series of posts (started on March 20, 2015) about the importance of collaborations and Chinese solar companies, another company worth noting is BYD Company, an acronym derived from the phrase “Build Your Dream“.  BYD Co Ltd (simplified Chinese: 比亚迪股份有限公司; traditional Chinese: 比亞迪股份有限公司; pinyin: Bǐyàdí Gǔfēn Yǒuxiàn Gōngsī) is a Chinese manufacturer of automobiles and rechargeable batteries based in Shenzhen, Guangdong province. It has two major subsidiaries, BYD Automobile and BYD Electronic. Hailed for its innovations, BYD has grown to become a major manufacturer of rechargeable batteries, most notably mobile phone batteries. BYD topped the 2010 Bloomberg Businessweek Tech 100 list, a list of large, fast-growing tech companies.

During the World Smart Energy Week 2015 (Feb. 25-27, 2015) in Tokyo, Japan, this has been presented about BYD, below (in italics):

———————————————————————————————————————————————————————-

BYD Co., Ltd is a leading-edge provider of green energy technologies that specializes in the IT, automotive, and new energy industries. Being the world’s biggest rechargeable battery manufacturer, BYD also has the largest global market share for cell-phone chargers and keypads. BYD branched out into the auto business in 2003, and has kept a robust yearly growth rate successively. In 2008, Warren Buffett invested $232 million to take a 9.89% stake in BYD. Today, BYD is the fastest-growing Chinese auto company and a global pioneer in the field of new energy vehicles including Dual Mode Electric Models and Pure Electric Models.

Based on its core Fe Battery technology, BYD has worked out a Green City Solution, which aims to electrify urban public transportation systems by transitioning from gasoline and diesel buses and taxis to pure electric ones. In March 2012, BYD and Daimler AG officially announced the entirely new EV brand Denza in China.

In addition, BYD has also focused on the Research & Development and manufacturing of a wide range of new energy products, including energy storage system, solar energy products and LED lighting .

In 2014, BYD and Strata (Strata Solar of Chapel Hill, NC) worked together to implement BYD’s world leading battery technology into a series of Strata Solar’s utility farm projects in order to maximize production and efficiencies. Markus Wilhelm, Strata Solar’s CEO said “We have been very impressed with BYD’s focus on solar and storage technology. BYD’s renewable energy division is highly vertically integrated, which benefits from strong engineering competence, and research and production capabilities in panel manufacturing, racking, inverter technology, and comprehensive storage solutions. During our meetings with Chairman Wang and his staff we had the opportunity to confirm Strata’s alignment with BYD’s global vision and strategy for solar energy. Strata’s unique and rapidly growing utility scale solar business will provide BYD with a large and scalable platform for their current and new technology.”

Strata Solar completed nearly 200 MW’s of solar across 30 installations in 2013. Strata added 300 – 400 MW’s in 2014 and has a pipeline of 1.5 gigawatts in the making. Residents in North Carolina have benefited tremendously from such collaborations that they are expanding their reach (to be presented in our next post).

————————————————————————————————————————————————————————–

With its combined expertise in PV and storage, BYD is providing comprehensive on-and off-grid solutions in various markets as power storage becomes an important component of PV solution. The company has shipped about half of its storage solutions to solar and the other half to other renewable energy applications.BYD has also collaborated with the U.S. multinational energy company Chevron in a project in the Middle East. For residential PV market in the U.S., where residential users pay the highest prices for electricity in the morning and evening, utilizing the DESS (Distributed Energy Storage System) of BYD, homeowners can tap the stored electricity in the morning and then do the same in the evening after the PV system has provided new energy to the battery. And during the night, the battery can be charged using power provided from the grid at off-peak rates.

Other international collaborative efforts: turning to Taiwanese cell manufacturers or setting up production facility in the U.S. in coming up with a duty-free solution for the U.S. market;expansion of module production plant in South Africa;partnership in Europe via juwi Holding AG in Germany for solar panels; positioning itself for the Japanese large-scale ground-mounted PV market; teaming up with the Canberra-based utility AGL Energy in supplying panels to a 400 MW PV project in Australia. With its chain of R & D centers in Shanghai, Ningbo, and Shenzhen providing strong base and its four 100 MW module production lines in Shanghai, BYD’s competitiveness is assured going forward in energy storage, solar energy products, and transportation vehicles.

It is clear that in order for any company, solar or otherwise, to succeed, the name of the game is: Solving Problems and Collaborations.  In our 21st century global economy, barriers such as tariff or anti-dumping tariff no longer works. Our future belongs to those who are able to solve problems and to collaborate with others from all parts of the world. The sooner we all realize this and free ourselves from the obsolete mode of thinking, the better we will be able to play the game of Building Our Economy and Going Green.

Students Bring Solar Farm to Middlebury College

Share

Dear Readers,

(Please click onred linksbelow)

If you are in favor of renewable,  clean, or solar energy, please sign this petition for FIT/CLEAN Program, accessible at http://sunisthefuture.net/?page_id=1065 Thank you very much.

Dear Friends & Readers,

If any of you solar enthusiasts should be visiting/driving through the state of Vermont later this year, you may want to visit Middlebury, Vermont.  Construction work is currently underway at Middlebury College for what will be Middlebury’s largest solar-power station.  Less than a half mile from the campus of Middlebury College, ground is broken on Route 125 for a 1.5 acres solar farm West of McCardell Bicentennial Hall, Middlebury’s Science facility.  In Spring of 2012, this solar energy system will join Middlebury College’s biomass plant and wind turbine on campus.  Middlebury College’s officials have signed an agreement with Williston-based AllEarth Renewables to create a small solar farm consisting of 34 solar trackers that will produce an average of 200,000 kilowatt-hours annually.  This installation will produce enough electricity for a year for one of the college’s residence halls the size of Battell Hall (housing about 238 students).

The AllSun Trackers (more on this in the next post of sunisthefuture.net) is the innovative solar energy system manufactured by AllEarth Renewables.  David Blittersdorf, CEO and founder of AllEarth Renewables, said that the solar trackers, mounted on poles, uses GPS and wireless technology to actively follow the sun throughout the day, producing more than 40%  energy than fixed solar panels of the same size.  “We’re excited to have this system to explore the potential for additional solar power in the future,” said Jack Byrne, Middlebury College director of sustainability integration. “This is a demonstration project that offers an opportunity for student learning and research as well as one more option to explore as we pursue our goal to become carbon neutal by 2016.  Staff will also have the chance to gain an understanding of the operational aspects of a solar energy system.”

According to Dean of Environmental Affairs Nan Jenks-Jay, students have expressed interest in developing a solar energy system at Middlebury for several years in a number of academic courses.  Four students in Professor of Economics Jon Isham‘s fall semester “Environmental Economics” class wrote a report, “The Cost-Benefit Analysis of a Proposed Small Scale Solar Farm at Middlebury College,” concluded that a project with AllEarth would have a positive economic and social impact.

 In 2010 students in an environmental sutdies seminar taught by Professor of Environmental and Biosphere Studies Steve Trombulak also recommended the college commission a solar project with AllEarth.

Hear! Hear! For these students at Middlebury College who were responsible for the final nudge to instigate this project that will provide economic benefit and solar power for Middlebury College.  Let’s hope that there will be more students throughout the country and our planet who will also take the initiative to bring forth learning opportunities for solar energy while benefiting their respective institutions.

Solar Water Heater-How It Works (2)

Share

If you are in favor of renewable/CLEAN energy, please sign the petition page showing support for FIT/CLEAN Program at http://sunisthefuture.net/?page_id=1065 Thank you.

Remember that we are discussing this topic, Solar Water Heater-How It Works, in honor of Ed Begley Jr.. The use of solar water heaters to heat water had a long history in countries/regions where sunlight is readily available.  As a matter of fact, in US, the first solar water heater dates back to 1890s.  By 1920, tens of thousands of solar water heaters were sold in US. However, the use of solar water heaters dwindled once the cheaper fossil fuels became available.  Yes, that was a different time in history and solar water heaters have again made a comeback in US and elsewhere  now that the cost of fossil fuel has gone up. Let’s look at some data/pie chart from 2007 at right   (click on the pie chart would give you a higher resolution view).

new solar hot water installations during 2007

There are mainly two types of solar water heaters:

  1. Active solar water heating systems: where pumps enable the flow of water through the solar water heating systems.
  2. Passive solar water heating systems: where most of the circulation of water occurs naturally, therefore no pump is use

(A) Passive CHS (Convection Heat Storage/thermosiphon)system with tank above collector. (B) Active system with pump and controller driven by a photovoltaic panel

Active systems can tolerate higher water temperatures than in equivalent passive systems, but active systems are often more efficient, more complex, more expensive, and more difficult to install than passive systems and rely on either mains or PV sourced electricity to run the pump and controller.

Since no body ever remembers a long winded speech (as Dale Carnegie once commented)….so let’s keep this one short also.

More of the solar water heater will be discussed in my next post. Stay tuned in at the same bat channel, sunisthefuture.net

Until then, I bid you well~
