A new solar electricity generation system that developers claim is the most efficient in the world, is being tested in South Africa’s Kalahari desert. The Swedish company behind the project - which combines military technology with an idea developed by a 19th-century Scottish engineer and clergyman - says it is on the verge of building its first commercial installation. In the remote Northern Cape province, huge mirrors reflect the sun
Researchers at Michigan State University have created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really is transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research, the team are confident that
Ultra-high efficiency solar cells similar to those used in space may now be possible on your rooftop thanks to a new microscale solar concentration technology developed by an international team of researchers. "Concentrating photovoltaic (CPV) systems leverage the cost of high efficiency multi-junction solar cells by using inexpensive optics to concentrate sunlight onto them," said Noel C. Giebink, assistant professor of electrical engineering, Penn State. "Current CPV systems are the
Robust & Extreme ConditionsJust in case you were wondering how well the Solar Royal (SR1800 Series) solar attic fan (ventilation fan) stacks up, we just received KUDOS via the following video testimonial on how our ventilation solution works even when covered in snow.This is what you can expect from a high-quality monocrystaline solar panel and high-efficiency brushless motor from Solar Royal.
CLICK TO VIEWDARE TO COMPARE: we have earned countless customers around the nation with our 'Dare -to- Compare' campaign which is fundamentally pushing our potential customer to ask questions and take the time to compare the differences if they are considering anything other then a Solar Royal solar attic ventilation fan.
- High quality monocrysataline solar panel

Berkshire project owners to target water utilities with scheme to cut energy bills, reports BusinessGreen A farm in Berkshire has become the first in the UK to install a floating solar array, with the owners now targeting water utilities and reservoirs for further development. Sheeplands Farm near Wargrave switched on the 200kw solar array last month, which is located on a reservoir and is expected to slash the businesses’ carbon
An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for sustainable energy biological systems powered by sunlight which could manufacture hydrogen as a fuel. "Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and do it cheaply and safely," said Dr Kastoori Hingorani, from the ARC Centre of Excellence for Translational Photosynthesis
When you think about how fashion will work alongside technology in the future, it might be hard to break from science-fiction-heavy ideas. However, fashionably using solar, wind and even kinetic energy to charge devices, keep us connected and even donate our energy to non-profits is being explored by a number of design houses. Meg Grant, of Solar Fiber, says she and co-collaborators Aniela Hoitink, Marina Toeters, Ralf Jacobs, and Professor Derek Schlettwein from Giessen University
Last week, for the first time in memory, the wholesale price of electricity in Queensland fell into negative territory – in the middle of the day. For several days the price, normally around $40-$50 a megawatt hour, hovered in and around zero. Prices were deflated throughout the week, largely because of the influence of one of the newest, biggest power stations in the state – rooftop solar. “Negative pricing” moves, as they are known, are
In the race to roll out "greener" school buses, seizing solar energy advantages, electric school bus projects are increasingly making Northern California School District Debuts First Solar-Assisted Electric Bus, with the latest news coming out of California's Silicon Valley. Health advocate Breathe California and Gilroy Unified School District have unveiled a full-sized electric school bus converted from diesel that is part of a new pilot project. The ribbon-cutting event drew
Residents are more likely to install solar panels on their own homes if their neighbours have also embraced the technology. A study by Yale and New York University investigating the effects of social interaction on adoption of solar photovoltaic panels -- i.e. whether other people's enthusiasm for solar power is contagious -- discovered that an increase of just ten solar panel installations in a post code was accompanied by 7.8
