Science Plant a Wind Tree in your neighborhood to generate energy from low-speed wind

Bruce Brown for Digital Trends:  These trees do more than just add ambiance. Harnessing the wind to generate electrical energy usually brings to mind thoughts of huge land- or ocean-based wind farms consisting of huge towers with two or three blades, each more than 100-feet long, on the top. The size, weight, noise, and vibration of industrial wind turbines restrict their use to large open spaces. Newwind, a French startup, has developed a much smaller, urban-space-friendly “Wind Tree,” reports Electrek. The Wind Tree, which produces sufficient energy to power small buildings or streetlights, is designed to connect to a nearby energy storage system. The trees are each about 30 feet tall and 26 feet in diameter, and weigh approximately 5,500 pounds. Each tree has 54 Aeroleafs mounted vertically on tree branches. The Aeroleafs are 3.2 feet high and, spinning at optimum speed, are capable of generating 65 watts each. So, a tree with 54 leaves has an energy-generation capacity maximum of 3,510 watts (3.5kW), about the same as a small home solar installation.   Cont'd...

How to Manage Snow on Solar

The snow melting on your panels actually acts as a lubricant between the snow mass and the panel surface, which makes the solar panel a completely frictionless, slick surface that's the perfect candidate to allow that snow mass to come barreling off your roof.

PVinsights: Solar tumbles into a bear market

Solar panel prices move notably lower this week, extending the downward trend over the past few weeks. Record capacity expansion, historical low bidding prices and an oversupply situation are intensifying a worldwide competition, which in turn are fueling solar panel price drop. In the US, competition among major module suppliers is getting even more intense as major suppliers strive to secure more orders as to maintain high utilization rates and market shares. Other major solar markets also suffer from similar pattern. In China, even as the demand is relatively solid, solar panel prices are dragged down by depreciation of RMB as well as strategic pricing in efforts to win project tenders. As for India, solar panel prices slump as following the downtrend of the rest of the world regardless of its solid demand growth.

The Solar Industry Has Paid Off Its Carbon Debts

Robinson Meyer for The Atlantic:  Think of all the energy that goes into making a single solar panel. Quartz and copper must be mined. The raw materials must be converted into wafers, then encased in protective material. And after panels leave the factory, they must be shipped all over the world. Now imagine these consequences spread over four decades—the environmental cost of the solar industry. Given all the research, development, and production time that goes into making any one panel, a skeptical solar-buyer might wonder: Has the solar industry on the whole really saved any energy at all?  To that concern, a new analysis answers: Yes. The solar industry probably paid off its long-term energy and climate “debts” in 2011, a study published this week in Nature Communications finds.   Cont'd...

In its Largest Quarter Ever, U.S. Solar Market Saw Nearly 2 MW of PV Installed Per Hour in Q3 2016

The United States solar market just shattered all previous quarterly solar photovoltaic (PV) installation records. According to GTM Research and the Solar Energy Industries Association's (SEIA) Q4 2016 U.S. Solar Market Insight report, 4,143 megawatts (MW) of solar PV were installed in the U.S. in the third quarter of the year, a rate of one MW every 32 minutes. That pace is even faster today, as the fourth quarter will surpass this past quarter's historic total.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

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.
