Could the World be 100 percent Solar Powered

It’s pretty safe to say that we all know that we have to find an alternative to fossil fuels as soon as possible, and the most viable answer to the planet’s energy needs is visible to us any time we look upward. The amount of solar energy that hits just 1 square mile of this planet over the course of a year is equal to 4 million barrels of oil, and the energy that hits the Earth in a mere 40 minutes can fuel all of humanity’s energy needs for a year. Isn’t that incredible? Check out the infographic below to learn more about all the ways that solar power is the way to go, and how we can go about making it a reality worldwide.

Largest African Solar Energy Plant Comes Online In South Africa

JOHANNESBURG, —(eSolarEnergyNews)— SolarReserve, a leading global developer of utility-scale solar power projects and advanced solar thermal technology, today announced that the 96 megawatt (MW) photovoltaic (PV) Jasper solar power project completed construction and is fully operational, almost two months ahead of schedule. Jasper is located in South Africa’s Northern Cape in a solar park that also includes the 75 MW Lesedi solar power project which came online in May, and the proposed 100 MW Redstone concentrated solar thermal power (CSP) plant featuring SolarReserve’s industry-leading CSP technology with integrated energy storage.

The Jasper Project generated about 1 million man-hours during construction, peaking at over 800 on-site construction jobs. As part of the South African Renewable Energy Independent Power Producer Procurement Program (REIPPPP), the project will set aside a percentage of total project revenues for Enterprise Development and Socio-Economic Development for the benefit of the local communities.

«In addition to helping South Africa meet its critical electricity needs, the Jasper Project will bring long lasting economic benefits to the region,» said SolarReserve’s CEO Kevin Smith. «We look forward to continuing this positive momentum and bringing value to South Africa through collaboration on further projects, including our upcoming CSP projects that will provide South Africa with clean, reliable and non-intermittent electricity, day and night.»

With over 325,000 PV modules, the Jasper Project will deliver 180,000 megawatt-hours of renewable electricity annually for South Africa residents – enough to power up to 80,000 households through a 20-year power purchase agreement with Eskom, the South African power utility company. Selected by the South Africa Department of Energy (DOE) in the second round of bids under the REIPPPP, the project also marked Google’s first renewable energy investment in Africa.

The project was developed by a consortium consisting of SolarReserve, the Kensani Group (an experienced empowerment investment player in South Africa), and Intikon Energy (a South African developer of renewable energy projects). Equity investment and ownership for the project was provided by a strong group of international and South African shareholders who jointly have experience in all aspects of development, funding and operations of solar energy projects. The equity investment shareholders include the Public Investment Corporation (PIC), Intikon Energy, Kensani Capital Investments, Google, the PEACE Humansrus Community Trust, and SolarReserve with Rand Merchant Bank providing preference share equity. International law firm Baker McKenzie supported the project activities through its offices in Johannesburg and the United States, with Kensani Eaglestone Capital Advisory acting as financial adviser.

From Module Cleaning Robots to Flying Drones: Japan’s Growing Solar O&M Market

Although the non-residential segment represents 57 percent of the existing installed capacity, it represents 96 percent of the reserved capacity. The fast-growing non-residential PV capacity makes Japan one of the hot markets for PV Operations and Maintenance (OM) services.

Fuji Keizai Co., a research and consulting company, forecasted that the 2013 non-residential PV OM market in Japan will almost quadruple by 2020. The research firm specifically projected that the maintenance market will grow from ¥1.5 billion in 2013 to ¥8.2 billion in 2020 and the operations market will grow from ¥16.3 billion to ¥60.4 billion. 

To meet the growing OM demand cost effectively and efficiently, Japan is turning to high-tech gadgets. 

Sohgo Security Services Co, known as ALSOK, is a leading security services provider in Japan. The company currently has the largest market share in PV security monitoring for large-scaled, ground mount PV systems. “We install infrared or thermal camera systems around perimeter fence lines and provide 24/7 surveillance monitoring services from central monitoring centers located throughout the nation. We monitor and detect module or copper wire thefts, which occur during construction and also wild animals that damage wiring systems during operation,” said Hiroshi Fujisawa at ALSOK.

ALSOK’s solar customers approached the company and asked whether it could provide module inspection services as well. Having developed security robots, the company expanded its expertise into “flying” robots — unmanned aerial vehicles (UAV), otherwise known as drones — to conduct panel inspections from the air.

Drones equipped with high-definition and thermal imaging cameras can detect malfunctioning modules, specifically hot-spots, which can reduce electricity production. The company also takes aerial photos for site surveys and to monitor construction progress using an autonomously operated drone. Currently in the US, San Francisco-based Skycatch offers very similar services for SolarCity and First Solar. 

ALSOK launched the testing service with drones in October for its existing customers who subscribe to its PV security monitoring services. Using a drone is a cost competitive alternative to taking aerial photography from a helicopter or using manual labor to conduct inspections in –large, remote fields.

“It takes 15 minutes (for a drone) to fly over a 2-MW system to collect necessary data for inspection while it will take about three hours to check 2 MW worth of modules by hands,” said Fujisawa. With a fully charged battery, a drone can fly for about 25 minutes and the company currently charges ¥200,000 – 300,000 for one fly.  The company will make this service available to any customer, including wind projects, starting April 2015.

There is another type of robot working for the growing solar PV OM market in Japan.  Sinfonia Technology Co. developed iRobot’s Roomba-like cleaning robots called “Resola” that autonomously scrubs the module surface with water.

Even in Japan where there is a reasonable amount of rainfall, solar modules still gather dust, dirt, and other debris that can block sunlight and reduce electricity generation. “Dragonflies lay eggs on PV modules, seeing blue PV modules as water,” said one PV project developer in Japan. This misdirected instinct can cost PV owners unless modules get cleaned up in a timely manner to ensure maximum productivity. 

Bird droppings also pose a serious risk. “During cold seasons, waterfowls land on PV modules to warm up themselves and leave some droppings. When it doesn’t rain, droppings get dried out and stay on modules,” complained another project developer. 

Sinfonia Technology has over 100 years experience in developing electric machinery, from printers to aerospace power generation systems, and has applied its mechanical expertise to develop the autonomous cleaning robot with water, which cleans not only loose dirt and debris, but also stuck-on messes like bird droppings.

Resola is approximately 26 inches (670 mm) in width, 21 inches (545 mm) in depth, and 6.8 inches (173 mm) in height. “It weighs less than 44 pounds (20 kg) so that one person can carry it easily,” said Koichi Dakimoto at Sinfonia. It runs on a rechargeable lithium-ion battery and a full charge equals about five hours of operation time.

The robot cleaner is currently targeted for ground mount systems at tilt angles of 5-20 degrees and applicable only for mono- and poly-silicon solar modules. Like Roomba, it has a self-navigation system. Resola’s infrared sensors allow it to climb up the slope from the bottom of the system, detect edges (or cliffs), and continue moving horizontally and then down the surface of the system, without falling.

Furthermore, to prevent Resola from slipping from the sloped, wet module surface, its wheels are covered with non-slip rubber like shoe soles.

Resola cleans solar modules with a spinning brush and squeegee, which moves like a windshield wiper blade. It moves from the top to the bottom of the slope so that debris and dirty water are gathered at the bottom.  A tank holds up to 2.7 liters of water, which can cover about 246 square-feet or 45 modules on average. “The cleaner comes with three settings: Under the hard-scrub setting, the tank lasts for about 30 minutes while 90 minutes under the gentle-scrub setting,” said Dakimoto.

When the battery power level or water level become low, for safety, Resola is programmed to move down to the bottom of the slope and waits for the battery to be exchanged or for the water tank to be filled. The company is currently marketing Resola exclusively for the domestic market.                             

As the number of PV installations has significantly increased in such a short period of time, project developers have come to realize that PV is not maintenance free and it can cost a considerable amount of money to keep the system shipshape and operating at the maximum level.  In the growing Japanese PV market, cost-effective and efficient OM tools and services will have a significant role in minimizing OM costs while maximizing production revenues.  

Positioning Solar Production for Global Export, Protected Markets

The move also may foretell a trend toward the establishment of more capacity where local content is an issue.

“By manufacturing cells and modules in Malaysia provides them with direct access to the U.S. market without any trade case questions asked,” observes Finlay Colville, the vice president of NPD SolarBuzz, in London. “Hanwha’s flagship in terms of excellence is the Q CELLS side, while the SolarOne operation can supply the domestic Chinese market,” he explains.

Seong Joo Ryu, the managing director of Hanwha Q CELLS Malaysia said at the time of the announcement, ”Hanwha Q CELLS Malaysia is ready to become the company‘s main hub for the sustainable mass production of high quality solar cells and modules at competitive costs.” The company also touted its combination of “German engineering” with “international production.” The Malaysian location selection also will provide production cycle time and logistics savings from the combining of cell and module manufacturing at one production site, the company adds.

Similarly, China’s Comtec recently announced plans to add 300 MW of wafer production in Malaysia, aimed largely at the U.S. market.

Moving some solar manufacturing capacity into new target countries is also a rising need in many emerging solar markets. “In a number of new markets in Latin America, the Mid-East and in Africa, there is a tendency with government-backed initiatives to have something in place related to domestic content, so to win big tenders and auctions in the region, it clearly helps if you have manufacturing locally,” says Colville.

“This was seen in South Africa with the first few tender runs, where there was a strong focus on employing people locally to assemble panels,” he notes. “Most of the local plants are just assembling modules, not making cells; it is designed just to get a foothold in the market,” he says. Among the latest in-country plant moves is a plan by Solar Cluster, the southwestern German industry association, to establish a manufacturing plant in Brazil.

Malaysia itself has ambitious plans for solar power development, with a target for its installed solar base of 220 MW by 2020. In June, Frost Sullivan reported that, “As per the Tenth Malaysia Plan, the country aims to account 5.5 percent or 985 MW of the total generating capacity through renewables by 2015, and 11.0 percent by 2020. Along with this, the country is also aiming to reduce carbon footprint to 40.0 percent below 2005 levels by 2020. To achieve these goals, the country introduced…a feed-in tariff policy in 2011.”

Hanwha Q CELLS expects construction of the module production facility at the Cyberjaya site to start in early 2015, and the four new production lines are expected to be online for testing in Q3 2015, with full production slated for early 2016.

GCL-Poly Mops Up China’s Chaori Solar Mess

But the interesting element comes from the fact that many of these insolvent companies enjoy strong backing from their local governments. That means that once all the finances are cleaned up for these insolvent firms, they could actually become good longer-term assets for their new owners.

The short-term headaches for solar buyers are evident in the recent mixed fortunes for Shunfeng Photovoltaic (HKEx: 1165), which looked like a rising solar superstar when it purchased bankrupt former solar superstar Suntech. But Shenfeng’s fortunes have suffered a sharp setback in the last month, as the Suntech effect wears off and people realize the turnaround story could be long and difficult.

We’ll come back to the Shunfeng-Suntech story shortly, but first let’s look at the latest news that has the parent of GCL-Poly leading a group that will buy 66 percent of Chaori for 1.46 billion yuan ($240 million). The deal was part of a broader restructuring for Chaori, which made headlines this year when it became the first company in modern China to default on a corporate bond.

The restructuring plan was approved by the Shanghai Municipal First Intermediate People’s Court late last month, and the buyer group has pledged to return Chaori to profitability this year and re-list it in 2015. That kind of pledge means that the buyer group has probably received key government support for the restructuring and will find a way to meet its targets, even if that means using aggressive accounting to return to profitability and calling on state-owned investors to make the new IPO a success.

It’s important to note that this GCL-Poly deal has several key differences from the earlier Shunfeng-Suntech one. In this case the buyer is actually GCL-Poly’s privately held parent, Golden Concord Holdings, meaning the risk associated with taking over Chaori isn’t being shouldered by the publicly listed company. In addition, the GCL-Poly parent is part of a larger group that includes 8 other members, and thus Golden Concord will only own 30 percent of Chaori after the deal, equating to an investment of about $72 million.

So, how have GCL-Poly’s shares reacted to the news? The stock has dropped steadily over the last 6 weeks, and is now down 17 percent from a peak at the end of September. That performance mirrors Shunfeng, whose shares have lost nearly half of their value over the last 2 months after media reports emerged saying a major solar plant it was helping to build had run into trouble.

I suspect the magnitude of the Shunfeng sell-off was at least partly due to profit taking after a big run-up in the company’s shares on high hopes after the Suntech deal. And in fact, Shunfeng’s shares are now almost exactly at the same levels where they were at the start of this year before they embarked on a major rally.

So, the next bigger question becomes: What’s ahead for consolidators like GCL and Shunfeng, whose actions are motivated as much by local politics as by commercial factors? As I’ve said above, the political element of the equation means the stocks could come under short-term pressure as they deal with financial issues related to their purchases. But the goodwill they receive from local governments could be quite valuable over the longer term, meaning the stocks could see some strong upside potential once the current messes get sorted out.

Bottom line: Solar consolidators like GCL-Poly and Shunfeng will suffer short-term pressure due to difficult acquisitions, but could be longer-term beneficiaries as they earn government goodwill for their actions.
