Our online reference center and resource guide is for solar development and installation professionals who make system component design recommendations and purchasing decisions in the commercial and utility scale market.
This paper examines the recent past and potential future of photovoltaic (PV) solar in terms of how it has compared with traditional generation and how, even without government subsidies, solar utility scale projects will reach a price per KWh that will be at - or less than - traditional generation, possibly as soon as 2014. Now is the time for traditional conservative thinking to re-examine the facts about solar energy and explore its potential for not only delivering more efficient and less costly power, but also for creating jobs and opportunities that jump-start economic growth. This jump-start would be possible because electricity drives... More »
The Principal Solar Institute (PSI) has launched the PSI PV Module Rating, the industry's first and only comprehensive, independent rating standard for comparing PV modules. The rating method is constructed without bias: PSI has no affiliation with any PV module manufacturer and no interest in promoting one over another. The ratings are designed to allow large-scale solar consumers to make informed, intelligent comparisons and decisions when selecting PV modules. The PSI PV Module Rating is a comparative number that can be used with pricing information to provide power plant designers, buyers and financiers with a consistent basis for choosin... More »
In the summer of 2011, Texas experienced extremely low reserve margin periods throughout the state…causing average wholesale electricity prices to skyrocket to more than twice their normal level. Given that Texas is expected to add another 14 million to its population between 2010 and 2030,1 these shortages raise alarms about the state’s ability to meet future energy demand. Success will depend upon finding the most effective way to incent the development of more capacity. Unlike many other states, Texas has had a competitive retail market for electricity since 2001, replacing the traditional cost of a service-based regulated ma... More »
Concentrated solar thermal and photovoltaic solar technologies have evolved independently for decades, and both are approaching "grid-parity" power prices in many applications today. This paper will explore the different situations where each technology succeeds or fails in today's electric power generation marketplace, specifically excluding non-electric applications such as solar hot water heating. As of 2012, PV has come to dominate all smaller-scale solar electricity applications, while retaining the majority market share even in commercial and utility-scale applications. CSP retains a strong niche at the utility-scale and in combined hea... More »

There are surprising similarities in the way German and Texas think about their electricity markets. Both are fully deregulated and competitive. Both have large and growing amounts of wind and solar power. Both have economically-efficient “energy-only” markets, where power producers get paid for their energy, not for providing stand-by capacity. And both have questions about market structures and avoiding blackouts.

Lesley Stahl reports on how Duke Energy is handling over 100 million tons of coal ash waste in North Carolina
I grew up in South Carolina with Duke as my utility and my impression was that they are well admired as a utility, community citizen, and employer. But they clearly could do better with coal ash, and I think that solar will be part of their solution.
They did a good job today of providing more information to those who want to solve the problem, and not just ye...

A Deeper Look into Yieldco Structuring October 7, 2014 10:25am
A Deeper Look into Yieldco Structuring: Yieldcos seem to be the renewable energy financing mechanism in vogue lately. As the newest 2014 headliners, TerraForm Power and NextEra Energy attract media attention, and NRG Yield continues to exceed expectations, many industry stakeholders are asking: what is a yieldco and why is it attractive from an investment and finance perspective?

SEIA calls for investment tax credit rethink March 28, 2014 11:29am
SEIA calls for investment tax credit rethink: The Obama administrations budget proposal allows the U.S. Investment Tax Credit (ITC) to expire on December 31, 2016. The 30% ITC will be replaced with a Production Tax Credit (PTC) equivalent to $0.022/kWh.
Fuel cell and small wind project investors will also lose out on the 30% tax redemption offered by the ITC with geothermal, microturbines and combined heat and power projects set to lose a 10% allowance under the credit, at the end of 2016.

Solar Less Than 5¢/kWh In Austin, Texas! March 28, 2014 11:21am
Solar Less Than 5¢/kWh In Austin, Texas!: Solar power is apparently going to be sold to Austin Energy for a tiny bit less than 5¢/kWh under a new 25-year power purchase agreement (PPA) with SunEdison.
It’s from two solar power plants totaling 150-megawatts of capacity — a 350,000-panel, 100-megawatt facility; and a 150,000-panel, 50-megawatt facility nearby.

Anatomy of a Deal: 4-Cent-per-Kilowatt-Hour Solar in Palo Alto
“The PPA takes advantage of the usual 30 percent investment tax credit, plus a generous five-year, 29-cent-per-kilowatt-hour performance-based incentive (PBI).”
“Rubin revealed that the project sold for $2.87 per watt and had a sub-$2.50-per-watt installed cost.”
This project was 398 kW distributed on 12 rooftops.
