Philadelphia Solar Love

If Philadelphia has its way, solar energy could be on its way to become as synonymous with the city as Rocky Balboa and the Liberty Bell. Recently, the city council unanimously passed a resolution aiming to install enough solar capacity to power 20,000 homes by the end of 2025 — an amount that will accelerate […] Read more


Solar: Leading the Nation in Job Creation

The last couple of weeks have seen a number of great stories published about the benefits that solar is bringing to the economy and the planet. Not only have we seen state rankings for solar potentialfrom the National Renewable Energy Laboratory, a look back at the incredible solar boom of 2013, and a roadmap for reaching 100 percent […] Read more


Multilayered Waveguide Array: Solar’s Big Opportunity?

A new study by researchers at the University at Buffalo explores the use of a nanoscale microchip component called a “multilayered waveguide taper array” that improves the chip’s ability to trap and absorb light. Unlike current chips, the waveguide tapers (the thimble-shaped structures pictured above) slow and ultimately absorb each frequency of light at different […] Read more


Can Solar Stock Super Returns Continue?

Any way you slice it, solar investing has been on a tear for the last year. Of the 69 solar stocks that the Roen Financial Report tracks, three quarters are up for the year. On average solar stocks have gained 85% for the year, with 60% of solar companies up in the double digits. What is most impressive is […] Read more


PACE Financing 101

With all of these solar acronyms flying around, the renewable energy conversation can often times get a little confusing. One of the more common acronyms we continually hear is PACE financing. So what exactly is PACE? Property Assessed Clean Energy (PACE) arrived on the scene in 2008 and continues to be a strong renewable energy development mechanism used […] Read more


Investors Flock to Commercial Solar Projects

Good news for commercial solar projects: According to a new report by Mercatus, an enterprise-level investment analysis and decision-making platform serving as the core “operating system” for solar energy investors, investor interest in commercial solar projects has more than doubled in the last 12 months.  The Mercatus Year-End Solar Investment Analysis is based on data from over 1,400 […] Read more


Veterans: 10% of Solar Workforce

More than 13,000 U.S. Veterans are already working in the solar industry, and the number is growing. That’s almost 10 percent of the workforce in the solar industry, according to a new report from Operation Free, a coalition of veterans and national security experts, and The Solar Foundation. The report also found that nearly 62 […] Read more


FreeGreenius: An App for Finding Renewable Energy Locations

The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has released a free version of the simulation program FreeGreenius. The program brings together technical and commercial aspects and is able to calculate the yield that a renewable power plant project will bring at a certain location. In addition, FreeGreenius determines how a system must be […] Read more


Are Home Owners Overpaying for Solar?

A recent analysis of nearly 17,000 projects reported to the California Solar Initiative has revealed a 40% average difference in the prices that solar contractors charge customers. It is a buyer beware market, with some solar contractors charging nearly double the price of others. From July through December of 2013, the average residential and small […] Read more


Graphene Moves Into Solar Cells

Researchers believe that graphene, among its other applications in energy, could be used as a transparent electrode in photovoltaic cells, replacing a layer of indium tin oxide that is brittle and becoming increasingly expensive. Wee Shing Koh of the A*STAR Institute of High Performance Computing in Singapore and co-workers have compared these two materials. They found […] Read more


Conergy Launches $100M Commercial Solar Fund

Germany’s Conergy, which like SunPower, both manufactures and installs soar arrays, today announced (Jan. 14) that it launched the Conergy Fund I program, a $100 million fund to support the development of large-scale projects in the U.S. The fund will finance solar projects between 500 kilowatts and 25 megawatts in size. “The Fund is ideal […] Read more


Can This Battery Save Energy Storage?

A team of Harvard scientists and engineers has demonstrated a new type of flow battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and solar far more economical and reliable. Under the OPEN 2012 program, the Harvard team received funding from the […] Read more


RIP: Ontario MicroFIT Program?

The Ontario MicroFIT program is a keg about to run dry. Nobody knows if there’s another keg in the cellar. The Ontario Power Authority isn’t saying. There are encouraging signs, but past experience has taught us to be pessimistic. We’ve been here once before. In October of 2011, following a provincial election, the program was […] Read more


Nonprofits: A New Frontier for Solar

The nonprofit sector would seem to represent a natural fit for the solar revolution. Nonprofits exist primarily to do good. A community center, a food bank, a nationwide health-related charity: all these try to give a helping hand to needy people in a particular geographic area, or to a specific group, or to the sick […] Read more
