Solar Energy Index Underperforms S&P in Q1 2016
In September 2015 SunGift Energy completed the UK's first 'solar carports' on the top decks of two multi-storey car parks.
Adam Vaughan for The Guardian: The amount of household solar power capacity installed in the past two months has plummeted by three quarters following the government’s cuts to subsidies, according to new figures. A fall in solar power was expected following a 65% reduction in government incentives paid to householders, but the size of the drop-off will dismay green campaigners who want take up on clean energy sources to accelerate. Data published by the energy regulator this week shows there was 21 megawatts (MW) of small solar installed in February and March this year, after a new, lower incentive rate came into effect. By contrast, energy department figures show that for the same period in 2015, 81MW was installed. Cont'd...
From North American WindPower: According to MAKE’s latest wind power outlook for North America, unprecedented long-term policy certainty in the U.S., along with a new climate-conscious government in Canada, will enable nearly 75 GW of total wind power growth in the region from 2016 to 2025. The production tax credit (PTC) in the U.S. was extended in December 2015 as a multiyear phaseout and will support a total of 44.4 GW of wind power additions from 2016 to 2021. However, as the value of the PTC phases down after 2018, several drivers must align to sustain wind power growth in the U.S. At the sub-regional level, Texas will lead wind power growth from 2016 to 2018, followed by the Plains and the Midwest. Turbine technology advancement and balance-of-plant cost reductions will continue to drive down the levelized cost of electricity (LCOE) of wind power and offset a portion of the lost PTC value from 2019. This will allow wind power to maintain a substantial share of new power generation demand, despite attractive costs for natural gas power and rising competition from solar photovoltaics. Last year, the U.S. alone added nearly 8.6 GW of new wind energy generation. Cont'd...
We asked one customer to model cost savings for us. Note that we didn't pay for this, and it was based on a real bid made in 2015.
While the U.S. Supreme Court in February 2016 decided to stay the Clean Power Plan, temporarily halting its implementation, many states, confident in the rule's legal merits, are continuing to make progress toward implementing it.
This is a fully integrated, complete system with build-in hybrid-inverters, solar MPP-trackers, battery chargers, anti-island Protection, battery storage, and BMS, also all necessary field wiring terminals and disconnect switches.
Emily J. Gertz for TakePart: Filmmaker Shalini Kantayya set out to show that climate change isn’t all gloom and doom. The result, Catching the Sun, ably makes that case but may still leave you inspired and infuriated in equal parts. This fast-paced and compelling new documentary, which premieres Friday in New York City and in cities nationwide during April, follows a diverse group of job seekers, activists, politicians, and entrepreneurs as they tap into the world’s growing solar powereconomy. Kantayya jumps between nations that have unequivocally adopted policies to speed up adoption of renewables and more fitful efforts here in the United States to expand solar energy—from a program in Richmond, Virginia, training unemployed men and women to become solar panel installers to a “Green Tea Party” member and energy independence advocate working both sides of the halls of power in Georgia.

Ben Walsh for The Huffington Post: There is a “substantial risk” that SunEdison may file for bankruptcy, the world’s largest renewable energy developer said in a regulatory filing on Tuesday. The company’s fall isn’t a referendum on the solar industry as a whole, as much as it is on SunEdison’s aggressive growth strategy fueled by excessive debt and financial engineering, analysts say. SunEdison “just thought they were smarter than everyone else,” said David Levine, the founder and CEO of Geostellar, a solar energy marketplace that has done deals with the company. The company’s shares have fallen steeply since they hit a high of $30 in July. They were at just $1.26 before the filing. The stock immediately dropped another 40 percent when the market opened after the filing, and the company was trading at just $0.59 by Tuesday lunchtime. “What happened from late-2014 to the middle of 2015, the company began embarking on a hyper-growth strategy,” S&P analyst Angelo Zino told The Huffington Post.

Panasonic HIT® panels recently set a world record for conversion efficiency at the research level (laboratory), a full percentage point increase over the previous record.
Li-ion solutions are both scalable and flexible in their power-to-energy ratio. The flexibility enables MTR-type solutions for high-power smoothing, medium-power options for shaping renewable output to meet a forecast, and high-energy systems for shifting of renewable energy to periods of peak load.
Each political party strives to differentiate itself in terms of platform and policy. Liberals tend to emphasize environmental aspects of solar and renewable energy, while conservatives like to encourage market forces for job creation and consumer choice. Both of these are great reasons to support solar, and that is why we see an opportunity for bipartisan support of this technology.
Anna Hirtenstein for Bloomberg Business: If you’re a power plant developer, chances are you’ll be selling renewables in a developing nation in the decades ahead -- even with fossil fuel prices bumping along historic lows. That’s been the conclusion for some time of the International Energy Agency and independent researchers such as Bloomberg New Energy Finance. A report out Thursday from the United Nations Environment Program using BNEF data gives more statistical backing for the trends. For the first time in 2015, more investment went into renewables than fossil fuels, and most of the money went to emerging markets. BNEF is hosting a conference in New York starting April 4 to bring together executives and bankers attempting to generate value from the boom. Here are six charts from the UNEP report showing why cheap oil and natural gas aren’t about to slow the rise of wind and solar.
Newly Built Concentrated Solar Power Plants - Time To Consider Flushing and Cleaning as an Industry Standard?
A recent research paper published in Applied Thermal Engineering highlights the importance of defined protocols to effectively flush and clean newly built facilities, which is needed prior to filling the system with expensive fluids, such as solar thermal fluids.
Perovskite solar cells hold much promise for cost-effective solar energy. However, heat stability is an issue, and can significantly limit the solar cell’s long-term efficiency. A team of scientists led by Michael Grätzel’s lab at EPFL has now developed a cesium-containing perovskite solar cell that has achieved efficiency of 21.1%, as well as record-level reproducibility. The work is published in Energy and Environmental Science. By adding cesium, the EPFL scientists, led by postdoc Michael Saliba, made the first ever triple-cation perovskite mixture (Cs/MA/FA). The new films are more heat-stable and less affected by fluctuating surrounding variables such as temperature, solvent vapors or the heating protocol used for the device. But more importantly, they also show stabilized power-conversion efficiencies of 21.1% and outputs at 18% under operational conditions, even after 250 hours. “This is an absolute breakthrough,” says Michael Saliba. “These properties are crucial for commercializing perovskite photovoltaics, especially since reproducibility and stability are the main requirements for cost-effective large-scale manufacturing of perovskite solar cells.” Source AZOCleantech...
