Do We Really Need Solar That’s Too Cheap to Meter?

on May 6, 2016
greentech mediaLarge amounts of wind and solar drive down market prices — a phenomenon known as the merit-order effect. And if wind and solar producers are dependent on those market prices for their income, they will also drive down their own revenues. 
 
In other words, the more wind and solar we have, the less value they offer in reducing costs from other sources.
 
In a new paper in Nature Energy, Shayle Kann of Greentech Media and Varun Sivaram of the Council on Foreign Relations sound the alarm, arguing that solar will face economic troubles as it becomes a significant part of the power supply.

Top 10 solar module manufacturers in 2015

on May 4, 2016

PVTechThere should be no surprises regarding the top five ranked PV module manufacturers in 2015, as they form the backbone of the key six-member ‘Silicon Module Super League’ (SMSL), which PV Tech highlighted in late November 2015.

The Top 10 PV module manufacturers list for 2015 is based on actual module shipments through the first nine months of last year and guidance figures as well as detailed analysis of over 45 leading manufacturers’ expected shipments for the full year.  

One of the challenges in assessing module shipments of the top 10 producers last year was the rapidly deteriorating business position of SMSL member, Yingli Green.

California Winery Uses Solar Power And Energy Storage

on May 4, 2016

cleantechnicaThe Stone Edge Farm and winery in Sonoma, California has a 32 kW solar array, 14 of Aquion’s 25 kWh M-Line battery modules, and an Ideal Power 30 kW multi-port power conversion system. The solar PV array provides electricity to the primary residence, workshops, and offices. The renewable electricity system is generating so much power that some can be sold back to the local utility.

It is also part of an onsite microgrid which was designed for self-consumption, load shifting, and peak shaving. “The Stone Edge Farm project is an excellent example of how long-duration advanced batteries plus solar PV can enable on-site renewable energy generation and maximize solar self-consumption,” explained Scott Pearson, CEO of Aquion Energy.

5 Trends Shaping the 66GW Global Solar Market

on May 3, 2016

greentech mediaAfter a record-breaking 2015, GTM Research expects the global solar PV market to grow 21 percent and add 66 gigawatts of capacity by the end of the 2016. Tempered by policy pullbacks across major markets China, Japan and the U.K., PV growth will slow in 2017, but the market will reach 95 annual gigawatts by 2020.

Below are some of the key trends GTM Research identified in its new report, Global Solar Demand Monitor: Q2 2016.

Why Cities Are So Well-Suited to Renewable-Energy Growth

on April 30, 2016

WSJ

Last week, 175 countries signed onto a global agreement to significantly reduce carbon emissions in the face of the threat of climate change. Many of those same countries—particularly India, China, and Nigeria—are simultaneously experiencing major urbanization trends that will move billions of people into cities over the next several decades. In fact, according to the United Nations, approximately 2.5 billion people will likely join the world’s urban population by 2050, almost entirely in Asia and Africa. By that time, two-thirds of the world’s population is projected to be living in urban areas, according to the United Nations.

Hawaii lawmakers push renewable energy storage incentives

on April 30, 2016

the washington times

HONOLULU (AP) – Hawaii has the highest rate of residents using solar panels in the nation, and lawmakers want to extend the state’s leadership role by offering incentives or rebates to those who buy batteries to store their renewable energy.

It’s an issue that’s important to residents of the island state, which has the highest electricity costs in the nation. The state’s largest utility proposed charging different rates for customers at peak times, such as night, when electricity costs are highest.

New Study Shows Renewable Energy May Always Need Government Support

on April 29, 2016

the heartland institute

A new study published by the Massachusetts Institute of Technology says renewable energy sources will be unable to compete with conventional energy without government support or high taxes on fossil fuels for at least a decade.

The authors also conclude renewable energy may always need government assistance to stay in business.

Wooden windows? New material could replace glass in solar cells

on April 3, 2016

energy harvesting journalWindows and solar panels in the future could be made from one of the best — and cheapest — construction materials known: wood. Researchers at Stockholm’s KTH Royal Institute of Technology have developed a new transparent wood material that’s suitable for mass production.  

Lars Berglund, a professor at Wallenberg Wood Science Center at KTH, says that while optically transparent wood has been developed for microscopic samples in the study of wood anatomy, the KTH project introduces a way to use the material on a large scale. The finding was published in the American Chemical Society journal, Biomacromolecules.
