Floating Wind Plan Could Finally Crack California's Offshore Market

James Temple for MIT Technology Review: Falling prices, improving technology, and smart public policies are changing the calculations.

Pollution might be blocking 25% of potential solar power, study finds

Nick Lavars for New Atlas: "I thought the dirt had to affect their efficiencies, but there weren't any studies out there estimating the losses. So we put together a comprehensive model to do just that."

The Many Fates Of Former Solar Decathlon Houses

Like the students' continual career evolution after participating in one of the most rigorous and comprehensive university competitions, the houses that have competed in the seven U.S.-based Solar Decathlons continue to find new purposes and opportunities all over the world.

Intersolar Q&A with Kristan Kirsh, NEXTracker

NEXTracker is thrilled to launch our latest product innovation, TrueCapture™. TrueCapture™ is a revolutionary new software-as-a-service (SaaS) plus hardware offering.

This Paint May Pick Up Where Solar Panels Leave Off

Katherine Lin for NBC News MACH: A team of researchers in Australia have created an experimental paint that attracts water molecules from the air and chops them up to produce hydrogen.

Report: U.S. solar demand could drop 66 percent if trade case succeeds:

Nichola Groom for Reuters: The U.S. solar industry would see two-thirds of expected demand dry up over the next five years if a trade case aimed at propping up the domestic panel manufacturing industry is successful, a new report said on Monday.

Capturing Energy with Nanotechnology

One goal of nanotechnology is to improve photovoltaic solar electricity generation. The thermodynamic limit of 80% productivity is well beyond the capabilities of current photovoltaic technologies, whose performance now is only about 43%.

Data Rules: Intelligent Solar Trackers Reduce Risk, Downtime and O&M Costs

Developing a predictable O&M strategy at the outset of a project will ensure the bankability and a robust ROI throughout the system's lifetime. Project owners and developers that thoroughly evaluate O&M considerations of their tracker investments will find that the higher energy performance, predictive analytics and long-term reliability of single-axis, self-powered trackers will provide a lower overall levelized cost of energy than fixed-tilt racking or conventional tracking systems.

Why Wind and Solar Are Better Together

Currently, wind generation sites are the cheapest version to build in the United States. Solar tends to be significantly more expensive to develop and construct. Creating one site for both forms is much more affordable, yet offers all the advantages covered above.

Panasonic Joins Push to Put Photovoltaics on More Car Roofs

By Chisaki Watanabe, Emi Nobuhiro, and Kevin Buckland for Bloomberg: The tech giant thinks solar roof panels are the future for hybrids and EVs.

Solar panels to be fitted on 250 trains in India

Climate Action UN: According to local reports, Indian Railways will install flexible solar panels and batteries to power lights and fans on board 250 of the network's trains.

Global Wind And Solar Costs To Fall Even Faster, While Coal Fades Even In China And India

This year's forecast from BNEF sees solar energy costs dropping a further 66% by 2040, and onshore wind by 47%, with renewables undercutting the majority of existing fossil power stations by 2030

Future trucks fueled by hydrogen created with solar power: Exhaust? Pure water vapor

Science Daily: Heavy-duty trucks will soon be driving around in Trondheim, Norway, fuelled by hydrogen created with solar power, and emitting only pure water vapour as "exhaust."

Why rising temperatures don't make solar power rise

Isha Salian for San Francisco Chronicle: Sunny skies sound like a positive for energy production, but this week's heatwave in California isn't a boon for solar power.

Why Design Matters for Solar O&M

When evaluating SATs, I want to consider whether the failure of any individual hardware component could threaten the system's overall production. In the case of a decentralized SAT, for example, each row's independent motor is powered by its own dedicated solar panel (with integrated battery backup), making external power cables obsolete.

Solar & Wind - Featured Product

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
