Manny Salvacion for Yibada: Singapore-based real estate investment firm Redwood Group has recently launched a 248-kilowatt (KW) pilot project in China. The company also signed a power purchase agreement with New York-based solar developer UGE International and its financing partner, Hong-Kong's Blue Sky Energy Efficiency Co. Under the Redwood deal, UGEI and Blue Sky would lease rooftop space from Redwood to operate solar panels and then sell the electricity back to Redwood, the building owner, at prices lower than grid rates. "The time is right now for solar on rooftop in China because the cost of putting a system on the roof is becoming much more attractive," said Tianyu Sieh, chief executive of Blue Sky. UGEI and Blue Sky have also partnered with real estate services firm Jones Lang LaSalle in China to offer the same model to its commercial clients. Full article:
Sunrun Chairman and co-founder Ed Fenster will present the keynote address about efforts to extend the federal ITC but also how to prepare for the various outcomes that could occur.
Greater utility familiarity with smart inverters, as well as the further evolution of guiding standards and grid codes, are likely to enable the gradual emergence of optimal electric utility rollout strategies.
Knowing the limitations of string inverters may tell you just why the Module Level Power Electronics segment - microinverters - is on the rise.
By Daniel J. Graeber for UPI.com: Small-scale solar installations in the United States account for about a third of the overall capacity on the grid, a report from the federal government said. The U.S. Energy Information Administration estimates total U.S. solar-power output in September, the last full month for which data are available, at 3.5 million megawatt hours. Of that, just more than 30 percent came from small-scale solar installations. "Generation from roof-top photovoltaic systems has become an increasingly important part of total solar generation in the United States," EIA AdministratorAdam Sieminski said in an emailed statement. A September report from the Solar Energy Industries Association, with support from green energy market adviser GTM Research, found second quarter residential solar capacity grew 70 percent year-on-year to 473 megawatts.

Many of the largest operational onshore wind farms are located in Germany, China and the United States.
There could be a limit on how much solar power can grow. That’s because the more solar power we add to the grid, the less valuable it becomes. It’s a simple supply-and-demand story: solar reaches peak generation during sunny afternoons, but there’s a limited demand for such additional power during those times. As a result, solar begins to compete with itself, driving down the price that utilities are willing to pay generators. Solar power accounts for less than 1 percent of the world’s electricity generation today, but as more is added to the energy mix, the economics become increasingly unfavorable. Shayle Kann, head of GTM Research, and Varun Sivaram, a fellow at the Council on Foreign Relations, cite recent studies of the grids in Texas and Germany that suggest the value of solar will be cut in half by the time it makes up 15 percent of the energy mix. A study of California’s grid concluded that if solar power were to reach 50 percent of the grid, it would be only a quarter as valuable as it was before any solar had been added. Kann and Sivaram combined the data from those studies to make the comparison below. Cont'd...
As the demand for higher kVA capacities of solar inverters keeps expanding, higher switching currents need to be accommodated by relays used in these applications.
Reporting by Vera Eckert for Reuters: German battery maker Sonnenbatterie has launched a scheme to connect households with solar panels and other consumers, aiming to better distribute surpluses of the renewable energy and help members to become more independent of conventional suppliers. The start-up company hopes the scheme, called "sonnenCommunity", will boost demand for its batteries which store solar power, allowing owners to use the clean energy even when weather conditions are not favourable. SonnenCommunity takes the storage idea a step further, allowing solar power to be shared among its members. Sonnenbatterie said the scheme would initially target the 1.5 million solar power producers who, if they sign up to the community, will receive a battery storage system with a starting price of 3,599 euros ($3,812). But eventually, the offer will also be open to non-producers, it added. If the idea of battery-powered buildings takes off, it could pose a challenge to traditional utilities such as RWE and E.ON, which still derive the bulk of their power from big centralised power stations running on fossil fuels.

by MIHAI ANDREI for ZME Science: In many the vast steppes of Mongolia, some things have remained unchanged for centuries. But some things have changed, and big time: according to a new report, almost 3 out of 4 Mongolian nomads are now using solar power. Even if your lifestyle is pretty much Medieval, you can still benefit from advanced technology – that’s the reasoning behind a new government initiative that encourages nomads to use solar power. Mongolia is a geographically large but sparsely populated country. Covering over 600,000 square miles, it only has a population of 3 million people. About 1.2 million of Mongolia’s citizens live in the urban capital of Ulaanbaatar, while the remaining population is widely dispersed throughout the country with a large number residing in rural areas. In total, about a quarter of the population consists of nomadic herders. The per capita income in Mongolia at the start of the millennium was about US$470 per year, with income amongst herders even lower. Cont'd...

In 1977, the cost of solar panels was US$76.67/watt and today, it is just US$0.613/watt
We envision our technology to be part of the next-generation of skyscrapers and commercial buildings, and installed in buildings around the world, providing a source of clean, renewable energy to help meet the world's growing energy demands.
The rapid development of the wind power industry has created a new set of challenges for China to address. Despite this, the GWEC still predicts that China will install an additional 100 GW by the end of 2019, exceeding the country's 200 GW target for 2020 a year ahead of time.
