Colorful Perovskites: NREL Advances Thermochromic Window Technologies

Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) report a breakthrough in developing a next-generation thermochromic window that not only reduces the need for air conditioning but simultaneously generates electricity.

Scientists see the light: new solar panel design could lead to wider use of renewable energy

Designing solar panels in checkerboard lines increases their ability to absorb light by 125 per cent, a new study says.

Transparent and Double-Sided Sun-Tracking Solar Panels Could Be the Future

Becoming more affordable or practical are essential steps in driving the switch to renewables. Still, more innovation needs to happen. The solar panel industry needs to see substantial changes, and thankfully, it looks like there are some on the horizon.

Producing Energy from Vibrations

Hypothetically, all vibration energy can be transformed into electrical energy; but there are certain types of vibrations that are preferred when the intent is to power a sensor or monitoring system. These vibrations need to have a steady vibration and a controlling frequency.

How Silicon Carbide is Changing Solar Power Systems

Silicon carbide enables solar inverters to be lighter, smaller and more efficient. Using silicon carbide power components instead of silicon for solar inverters can save 10 megawatts for each gigawatt and 500 watts/sec in operations, representing significant energy savings.

The Evolution of Solar Technology - How Photovoltaic Technology Has Developed and Why Nanotechnology May Influence the Future

Here, Dr Franky So, chief technology officer of nanotechnology research company Nextgen Nano, explains the historical developments of photovoltaic technology and looks to the innovations shaping the years ahead.

Improving Deep-Cycle Batteries Through Additives

Battery manufacturers have improved deep cycle battery performance through the use of additives, but not all of them result in the same benefit to customers.

Automatic Charging of EVs

Charging stations can be an eyesore in inner cities, and the bulky cables and plugs can also be an inconvenience in people's garages. Contactless inductive charging with coils embedded in the garage floor or the road surface has none of these visual or mechanical annoyances.

NREL Six-Junction Solar Cell Sets Two World Records for Efficiency

The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.

IDTechEx Research: Redox Flow Batteries' Advantages for Stationary Energy Storage Market

One of the main characteristics of this technology is the decoupled energy and power capacity. In fact, while the energy is stored in the electroactive species present in the electrolyte.

The Most Exciting Green Startups To Watch In 2020

The sharing economy has become an unstoppable force--and the collaborative, peer-to-peer economy has grown from a curious fad into the trend-to-beat-all-trends over the past decade.

SMALL WIND TURBINES FOR THE ENERGY SUPPLY OF THE FUTURE

Small-scale wind energy is still in the beginning phases in Germany. Yet interest in this technology is gaining traction in light of rising electricity prices and the sociopolitical direction we are heading in to invest more in renewable energies in the future.

Huawei Predicts 10 Trends in Smart PV for 2025

Over the next 5 to 10 years, renewable energy will assume a more prominent role as a main power source for power grids. Solar power, in particular, as the most noteworthy form of renewable energy, has a particularly bright future.

NREL Research Boosts Stability of Perovskites, Helps Silicon Solar Cells

A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell developed at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL).

New Solar Technology Could Generate Power at Night

This technology could represent a turning point in sustainable power. Scientists have been working for decades to make our way of life more environmentally friendly. One of the most critical aspects of this effort is to generate reliable alternative energy.

RBI Solar - Dahlia Has You Covered

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
