James Temple for MIT Technology Review: Falling prices, improving technology, and smart public policies are changing the calculations.
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."
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.
NEXTracker is thrilled to launch our latest product innovation, TrueCapture™. TrueCapture™ is a revolutionary new software-as-a-service (SaaS) plus hardware offering.
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.
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.
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%.
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.
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.
By Chisaki Watanabe, Emi Nobuhiro, and Kevin Buckland for Bloomberg: The tech giant thinks solar roof panels are the future for hybrids and EVs.
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.
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
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."
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.
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.

The IMO FireRaptor provides three forms of Solar Panel Rapid Shutdown to ZERO VOLTS in case of fire or other emergency: Manual Panel Shutdown to 0V Operated from Ground Level, Automatic Panel Shutdown to 0V at >85°C (185°F) Temperature, and an automatic Panel Shutdown to 0V on External Power Loss. The FireRaptor can be installed without any set-up and with any string inverter as its functionality is completely independent. "Plug & Play" style installation using industry standard connectors is easy, whether fitted to new installs or retrofitted to existing projects to upgrade fire safety functionality. Meeting NEC2017's regulation to switch DC current at the PV panel in under 30 seconds, FireRaptor is remains one of the safest and most effective means of isolating DC current at the source, and the only rapid shutdown with a 20 year warranty.
