As this result shows that the combination of two PV technologies can outperform the power generation of single junctions the significance of this result shouldn't be underestimated as it breaks the current limitations of solar technology and shows that higher performing modules can be expected to become part of the energy system ...

Energy suppliers face change. New forms of alternative energies, new network technologies and the transition to the digital world all present challenges. There are lessons to be learned about how to make the new world work.
The need for renewable energy is high, but governments need to commit to salvation of the future. Short-term goals shouldn't come at the cost of our future.
Nicholas K. Geranios for AP: Scott Brusaw has a vision for the nation's roads. He believes the solar-powered glass pavers his company makes could transform thousands of miles of pavement into a new energy source. His business, Solar Roadways, recently unveiled its first public installation, in a downtown plaza in this northern Idaho resort town. It's 150 square feet of hexagon-shaped solar panels that people can walk and bicycle on. The company is working on proof that the panels, for which it has a patent, are strong enough and have enough traction to handle motor vehicles, including semitrailers. "Our plan is to replace all the asphalt and concrete," said Brusaw, noting concrete occupies over 48,000 square miles in the U.S. "If you cover it with solar panels, we can make three times our energy needs." Solar Roadways is among a growing number of companies embracing renewable energy as the U.S. aims to reduce carbon emissions by one-third from 2005 levels by 2030. Cont'd...
The need for good data is foremost. A swing of just a half percentage point in the actual output of solar energy plants-compared to projected outputs-would represent about $165 million annually.
There are two standards governing EV charging. In the U.S. there is the SAE J1772 standard, while in Europe and China the IEC61851 standard is used.

Michael McDonald for OilPrice.com: In the future, when investors look back at the year that represented the turning point for clean energy, 2016 may be it. The industry overall is growing at a breath-taking pace, but perhaps not for the reason that some investors think. Energy storage rather than solar power and wind power are the real factors that are driving a revolution across the electrical power industry. Energy storage changes the equation, not only in the renewables space, but in the conventional utility space as well. The concepts of spin/non-spin reserve costs, peaker prices, and a variety of other conventional concerns for utilities, lose meaning in the context of efficient and cost-effective energy storage. While energy storage was available previously, it’s only today that costs are coming down substantially. Tesla’s economies of scale on battery storage are well-known, but small start-ups like Orison are finding ways to lower costs in innovative ways as well. The graphic below from a recent EPRI presentation highlights the role that multiple layers of costs savings can play in creating economical battery storage. Cont'd...
Lorraine Chow for EcoWatch: The race to build the world's largest solar power plant is heating up. California-based energy company SolarReserve announced plans for a massive concentrated solar power (CSP) plant in Nevada that claims to be the largest of its kind once built. SolarReserve CEO Kevin Smith told the Las Vegas Review-Journal that the $5 billion endeavor would generate between 1,500 and 2,000 megawatts of power, enough to power about 1 million homes. That amount of power is as much as a nuclear power plant, or the 2,000-megawatt Hoover Dam and far bigger than any other existing solar facility on Earth, the Review-Journal pointed out. "It's a big project," Smith told the publication. "It's an ambitious project." Cont'd...
India has surely set up an ambitious goal of 175 GW of Renewable Energy by 2022, with solar and wind as the mainstream players aiming 100 GW (60 GW of Grid Interactive and 40 GW Rooftop) and 60 GW respectively.
VTT is seeking a carbon capture technology for Finnish power and heat production plants. The first pilots were implemented, using wood pellets, at VTT's Bioruukki and the results are promising.
Kristin Falzon for EcoWatch: Sundrop Farms, a tomato production facility that is the first agricultural system of its kind in the world, celebrated its grand opening in Port Augusta, South Australia, Thursday. Instead of soil, pesticides, fossil fuels and groundwater, Sundrop Farms uses only solar power and desalinated seawater to grow tomatoes across 49 acres. The water is pumped into the facility from the Spencer Gulf about 1.2 miles away where it is desalinated to water the farm's 180,000 tomato plants. Cont'd...
There still seems to be some confusion in the marketplace surrounding specific types of tracking applications, especially when it comes to independent row, self-powered trackers (SPTs)
One area which benefits from digitisation is the evaluation of data from periodic turbine testing and inspection reports.
Nick Mafi for Architectural Digest: A typical typhoon produces wind speeds between 98 and 120 m.p.h. and usually leaves behind a trail of destruction. But a Japanese engineer has plans to harness a typhoon’s incredible wind energy and use it to power the nation. Atsushi Shimizu has just invented the world’s first typhoon-powered wind turbine—a roughly 18-foot structure that, with its three distinct prongs, somewhat resembles an egg beater. Don’t be fooled by the simple design, however. According to the Atlantic Oceanographic & Meteorological Laboratory, a mature typhoon can produce a level of kinetic energy equivalent to about half of the world’s electrical generating capacity. That means that after a single typhoon, Shimizu’s invention could power Japan for up to 50 years. Add in the frequency of the country’s typhoons—anywhere from three to seven each year—and the potential for massive quantities of renewable energy is unmistakable. Cont'd...

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
