Similar to the S&P 500 Index, the Solar Stock Index is a market cap weighted composite index.
Devon's first Tesla Powerwall reduces amount of electricity Mike and Jan buy from their energy company by 86%
A single solar system that will collect both thermal and electrical energy utilizing the same valuable and generally scarce south-facing roof.
To reduce our dependence on fossil fuels, it is important to explore different sustainable energy options
Don't get overwhelmed at the prospect of launching a solar lead generation program: if you focus on the basics, you'll have a great foundation for finding new customers.
Adding backup power provides a tremendous value to the customers in certain areas with unreliable grid. In combination with other values, this is a trend that is producing a very strong demand - stronger than we initially thought.
There were 20 completed solar energy transactions in Q3 2016, which represents the same number of transactions recorded in Q2 2016.
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...
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.
The Emerging Relationship between Distributed Energy Resources and the Transmission System
UL works with industry leaders to develop a new standard for microgrids, blending in-lab product testing with on-site field evaluations.
A customer can subscribe to as little as single panel or enough to zero-out their utility bill.
The global transportation fleet is turning electric faster than anyone could have imagined only a year ago.
Laura A. ShepardÂ for Popular Science: Â Picture a giant toilet bowl looming larger than life outside the UN headquarters in New York. It sounds like an absurd scene, but the stunt from three years ago was not a childish prank. It was a serious statement to mark the first World Toilet Day and raise awareness of the fact that one third of the world's population lacks access to toilets. Addressing the global sanitation crisis is a top priority among the UN'sÂ Sustainable Development Goals, and it now has an exciting solution. In fact, science may soon make your toilet bowl a viable alternative energy source. Your flushes can produce two or three gallons of biofuel per year when the wastewater is treated using a process, developed scientists and engineers at the Department of Energy'sÂ Pacific Northwest National Laboratory, called hydro-thermal liquefaction (HTL). HTL emulates the way crude oil forms naturally, when biomass decays under high pressure and heat for millions of yearsâ€Š-â€Šbut it only takes 45 minutes. Â 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.
