Microinverters and DC Power Optimizers Will Reach Nearly $2 Billion in Annual Revenue by 2020, Forecasts Navigant Research
Microinverters and DC optimizers, commonly referred to as module-level power electronics (MLPEs), increase the energy harvested by solar PV modules and reduce the levelized cost of electricity by converting or conditioning power at the module level. As a result, microinverters and DC optimizers are two of the most disruptive technologies in the solar PV sector today. Click to tweet: According to a new report from Navigant Research, revenue from microinverters and DC optimizers will grow from $308 million in 2013 to more than $1.9 billion in 2020. "The module-level power electronics sector has grown from a niche market to mainstream, especially in the United States, where there is fierce competition in major solar PV markets like California," says Dexter Gauntlett, senior research analyst with Navigant Research. "What's more, a growing number of solar PV module manufacturers are now integrating microinverters and DC optimizers at their own production plants. At the same time, large power electronics companies and incumbent manufacturers are making strategic partnerships and acquisitions to take advantage of rapid growth in this market segment."
Microsoft has announced it has signed a 110MW PPA with RES for a project in Texas, following Facebook and Google into wind power. The 110MW Keechi wind farm, located 70 miles northwest of Fort Worth, will power a Microsoft data centre in San Antonio, Texas. It follows the company's announcement last year that it planned to become carbon neutral. Construction of Keechi will begin early next year and will use Vestas 2MW turbines. The PPA is for 20 years. This is Microsoft's first move into wind energy. In doing so it is following a path set by Google, which has bought around 570MW of wind power in Texas alone. It had also invested and bought wind farms elsewhere in the US.
SunPower Corp. (SPWR), the second-largest U.S. solar manufacturer, bought Greenbotics Inc., maker of robots that clean panels to increase the amount of power they can generate. The robots clean dirt and dust off of photovoltaic and solar thermal arrays and cut water use by 90 percent, San Jose, California-based SunPower said today in a statement. Terms of the deal, the seventh acquisition SunPower has done since it was formed, weren’t disclosed. SunPower plans to use the systems at projects it develops, especially in the western U.S., the Middle East and Chile, as an alternative to pressure washers and sprayer trucks. The robots will cut water use, save money and boost annual energy yield in dry, dusty regions by as much as 15 percent, according to the release. “It’s half the cost of normal cleaning,” SunPower Chief Executive Officer Tom Werner said in an Nov. 1 interview. The technology, which he likened to a Roomba vacuum cleaner, “is one we can scale.”
Dec. 31 is a curious date for Texas wind energy producers. That's when transmission services providers expect to energize the last power lines built under the state's $7 billion Competitive Renewable Energy Zone initiative, the long-running effort to connect windy West Texas to the state's energy-thirsty big cities. The 3,600-mile project has been credited with spurring even more investment in Texas, the country's wind power leader. But 2013's last day is also an ominous one for wind folks. It's the expiration date of the federal Renewable Electricity Production Tax Credit, the fate of which has driven booms and busts in the industry. The multibillion-dollar credit, which Congress passed in 1992, helps wind stay economically competitive with other energy sources, including low-priced natural gas. Without it, the industry can't keep pace, even as production costs fall. Last year, as the credit neared its demise, Congress extended it as a part of a last-minute budget package, but only for a year. This year, with Congress focused on finding a way to turn the government back on and pay its bills, lawmakers have yet to draw up a proposal for the credit, making a swift renewal increasingly unlikely. So how would Texas wind power fare if the 2.3-cent-per-kilowatt-hour incentive lapsed? That would depend on how long the credit is unavailable, observers say. But for a couple of reasons, the effect probably won't be as harsh as in past uncertain times. Jeff Clark, executive director of the Austin-based Wind Coalition, said he's not too worried about the ticking clock. “There's a lot of projects in the pipeline right now,” he said. The 202-megawatt Baffin Wind Farm, in Kenedy County, is one project that's depending on the tax credit. However, owner and developer Iberdrola Renewables LLC isn't concerned.
A California energy storage startup has raised $5 million to fund projects that it will sell to businesses under long-term contracts, a model that resembles the leases that have made rooftop solar installations popular. Stem plans to use the money from Clean Feet Investors to finance up to 15 megawatts of lithium-ion battery systems. Stem is targeting hotels, chain stores, fast restaurant and light industrial companies, said Prakesh Patel, vice president of capital markets and strategy at the startup. Stem is one of a growing number of energy storage system and service providers that are gunning for California as their primary market. The state last week passed the country’s first mandate that will require its utilities to buy energy storage to help them manage the growing amount of solar and wind electricity that flows into the grid. Investors such as Clean Feet Investors will be the first wave of money managers who are willing to take big risks. Given that the energy storage market is so new, major banks are watching to see whether various types of storage equipment will deliver the promised performance over time and how money can best be made. Right now, many of them aren’t so willing to invest in what they consider to be unproven technologies. The new fund enables Stem to market to a broader set of customers. Businesses would sign contracts in which they pay a monthly fee for using the energy storage and Stem’s software, which collects and analyzes onsite energy use and other data in order to control how frequent and how much the electricity should flow in and out of the batteries throughout the day.

Federal officials are trying to figure out why the Bureau of Land Management's first-ever auction of public land for solar-energy development failed to attract any bids. According to the Denver Post, no bidders showed up for the first auction for three parcels of land in Colorado's San Luis Valley, even though five solar development companies had expressed interest in the land. Three parcels covering 3,700 acres in so-called solar-energy zones were offered on Thursday. The bureau has created 19 zones for large solar projects in six Western states, encompassing nearly 300,000 acres, the newspaper reported. "We are going to have to regroup and figure out what didn't work," Maryanne Kurtinaitis, the renewable-energy program manager for the BLM's Colorado division, told the Denver Post. "It is always tough to be the first out of the chute. This is a learning experience." Industry officials attributed the auction's failure to uncertainties about the solar energy market and federal regulations. Ken Johnson, a spokesman for the Solar Energy Industries, told the Post that financing large-scale solar projects remains a challenge for the industry.
Unique National Clean Energy Credentialing Alliance Created, Uses Solar Power International as Launchpad
In response to groundbreaking growth in renewable energy and energy efficiency industries, a group of highly respected, nationally accredited credentialing organizations announces the formation of a unique Clean Energy Credentialing Coalition (CECC). The Coalition was announced in conjunction with Solar Power International 2013 (SPI '13), the solar energy industry's most powerful, comprehensive educational conference and product exhibition, being held at Chicago's McCormick Place, October 21 - 24. The newly-formed group joins together organizations to demonstrate and promote the collective importance of third-party quality assessment, and the value it brings to building strong and competent renewable energy and energy efficiency markets. The Coalition is creating a campaign to build awareness of the value of credentialing - particularly as a distinguishing tool for consumers, energy incentive programs, employers and industry. A quality credential is a mark of excellence that can boost consumer confidence in renewable energy and energy efficiency professionals, products and programs. The goal of the campaign is to educate, enlighten and elevate interest in the benefits associated with clean energy credentialing - from consumers and educators, to manufacturers and government decision makers.

In a bold move being closely watched by utilities, environmentalists and the clean technology industry, California adopted the nation's first energy storage mandate for utilities Thursday. State regulators with the California Public Utilities Commission, meeting in Redding, unanimously approved Commissioner Carla Peterman's groundbreaking proposal that requires PG&E, Southern California Edison and San Diego Gas & Electric to expand their capacity to store electricity, including renewable energy generated from solar and wind. "The decision lays out an energy storage procurement policy guided by three principals: optimization of the grid, integration of renewable energy and reduction of greenhouse gas emissions," said Peterman, a rising star who was appointed to the agency by Gov. Jerry Brown in late 2012. The state's three investor-owned utilities must collectively buy 1.3 gigawatts, or 1,325 megawatts, of energy storage capacity by the end of 2020--or roughly enough energy to supply nearly 1 million homes. The ambitious 1.3 gigawatts is a capacity target, because different storage technologies have different rates at which they can accept and discharge energy, and the mandate aims to be technology neutral.
An insider fight over how much a utility company must pay for electricity generated by solar panels on private rooftops is boiling over into a full-fledged campaign, complete with shadowy money, expensive television advertising, calls for grass-roots action and some of the best pollsters and consultants money can buy. The feud between the utility and solar panel industries revolves around net metering policies, which govern part of the relationship between utilities and their customers. If the customers have solar panels that generate surplus electricity, the customers can feed that power back into the electric grid; utilities are required to pay the consumer a set rate for the electricity they generate. When those rates were first implemented, the nascent solar industry had few residential customers. But now, as more customers invest in solar panels for economic or environmental reasons, public utilities are starting to feel the pinch — and they want to stop paying rates they say are above market value for power they can’t always use. When the Arizona Corporation Commission holds its November meeting, commissioners will consider a request from Arizona Public Service Company, the state’s largest electric utility, to change those rates. The utility industry wants permission to pay rates below market value, and to charge customers who feed electricity back to the grid a monthly fee for maintenance costs.
The U.S. Department of Energy Solar Decathlon 2013 today announced the winners of this global competition among collegiate teams to build the most energy-efficient solar-powered house at the Orange County Great Park in Irvine, Calif. Team Austria, made up of students from the Vienna University of Technology, won top honors overall by designing, building, and operating the most cost-effective, energy-efficient and attractive solar-powered house. University of Nevada Las Vegas took second place, followed by Czech Republic, comprised of students from Czech Technical University, in third place. “The Solar Decathlon is inspiring and training the next generation of clean energy architects, engineers and entrepreneurs, and showing that affordable, clean energy technologies can help homeowners save money and energy today,” said U.S. Department of Energy Secretary Ernest Moniz. “Congratulations to the Solar Decathlon 2013 competitors – your hard work and creativity is helping to build a cleaner, more sustainable energy future.” Reflecting the quality of the Solar Decathlon 2013 houses, the winning teams’ final scores were the closest they have ever been since the beginning of the competition. Team Austria earned 951.9 points out of a possible 1,000 to win the competition, followed by University of Nevada Las Vegas with 947.6 points, and Czech Republic with 945.1 points. Contributing to their overall win, Team Austria performed well in several of the individual contests, finishing first in the Communications Contest, second in Market Appeal, and tied for first in the Hot Water Contest.

The global solar company Abengoa Solar has just announced that its massive Solana solar power plant has begun commercial operation in Arizona. The plant represents a transformational breakthrough in utility scale solar power, because it includes an energy storage system based on molten salt. The storage feature enables the plant to keep generating electricity long after the sun goes down. CSPs use mirrors to concentrate solar energy on a focal point, typically a large tower. According to Abengoa, at 280 megawatts the Solana plant is the world’s la rgest CSP plant to use parabolic trough mirrors to concentrate solar energy (typical CSP mirrors, called heliostats, are flat and quadrilateral). It is also the first solar plant in the U.S. with thermal energy storage, in the form of a molten salt system. The storage capacity is about six hours. That enables the plant to keep generating electricity from solar energy well into the early evening hours, when demand in the region typically peaks out. Solana officially went online yesterday after completing a series of tests that included charging the thermal energy storage system and demonstrating that it could produce electricity for six hours using only stored energy.
California’s three biggest utilities are sparring with their own customers about systems that store energy from the sun, opening another front in the battle that’s redefining the mission of electricity generators. Edison International (EIX), PG&E Corp. and Sempra Energy (SRE) said they’re putting up hurdles to some battery backups wired to solar panels because they can’t be certain the power flowing back to the grid from the units is actually clean energy. The dispute threatens the state’s $2 billion rooftop solar industry and indicates the depth of utilities’ concerns about consumers producing their own power. People with rooftop panels are already buying less electricity, and adding batteries takes them closer to the day they won’t need to buy from the local grid at all, said Ben Peters, a government affairs analyst at Mainstream Energy Corp., which installs solar systems. “The utilities clearly see rooftop solar as the next threat,” Peters said from his office in Sunnyvale, California. “They’re trying to limit the growth.”
The growth of wind power, if undertaken with reasonable care, should pose no risk to any particular bird species in Canada, according to a new peer-reviewed study. The study also suggests that highly publicized bird mortality figures out of the U.S. and Europe could be on the high side. “Canadian Estimate of Bird Mortality Due to Collisions and Direct Habitat Loss Associated with Wind Turbine Developments” was one of several studiesundertaken as part of special issue of the journal Avian Conservation & Ecology that focused on the impact of human activities on the mortality of birds in Canada. The researchers did find that, on average, a wind turbine in Canada results in 8.2 bird deaths per year, and they estimated that a 10-fold increase in installed wind capacity in the next 10-15 years “could lead to direct mortality of approximately 233,000 birds/year, and displacement of 57,000 pairs” resulting from habitat loss. But the researchers put those numbers in perspective: [T]hese values are likely much lower than those from collisions with some other anthropogenic sources such as windows, vehicles, or towers, or habitat loss due to many other forms of development. Species composition data suggest that < 0.2% of the population of any species is currently affected by mortality or displacement from wind turbine development. Therefore, population level impacts are unlikely, provided that highly sensitive or rare habitats, as well as concentration areas for species at risk, are avoided.
What do Bill Gates and Warren Buffett have in common? Apart from being very, very rich, it is a growing interest in battery storage and other “smart” technologies that will redefine the way our electricity grid operates – hopefully to the benefit of the consumer. Gates has built up a collection of energy storage investments – including Aquion Energy, Ambri, and LightSail - and Buffett is a major investor in Chinese electric car and battery developer BYD, soon to unveil a home battery storage solution in Australia. Last week, Gates and well-known cleantech investor Vinod Khosla last week bought into Varentec, a US company that is developing “smart” technology that will link storage devices and renewables, and lead to what Khosla describes as “cost-effective, intelligent, decentralized power grid solutions.” Energy storage, as described by investment bank Citi in its new “Energy Darwinism” report, is likely to be the next solar boom. Citi says the main driver of this investment will not be just to make renewables cost competitive, because they already are in many markets – but for the need to balance supply and demand. This, in turn, will make solar and other renewables even more attractive. It may even mean the end to the domination of centralised utilities, as storage will allow the industry to split into centralised backup (based around the old rate-of-return regulated utilities model) and much smaller “localised” utilities that harness distributed generation such as solar and storage.
