The Effect of State Policy Suites on the Development of Solar Markets

National Renewable Energy Laboratory (NREL), Nov. 2014.
http://www.nrel.gov/docs/fy15osti/62506.pdf

"Many states and local governments have undertaken a variety of policy initiatives with the goal of encouraging private investment and building robust solar photovoltaic (PV) markets. While some states have seen many-fold increases in solar PV installations over the last decade, many other states, some with similar policies, have been less successful. The perceived lack of a clear relationship between implementation of specific policies and increases in solar installations has been challenging to policymakers seeking to support solar markets within their jurisdictions."

Solar Photovoltaic Output Depends on Orientation, Tilt, and Tracking

Energy Information Administration, Nov. 19, 2014.
http://www.eia.gov/todayinenergy/detail.cfm?id=18871

"Financial incentives, renewable portfolio standards, cost declines, and system performance improvements have led to more customer-sited solar photovoltaic (PV) installations, especially in states such as California. Because PV panels are able to capture more solar energy when they are pointed directly at the sun, installers may configure systems to optimize output by adjusting the orientation and tilt of a system, or by using mechanisms that track the sun as it traverses the sky."

An Untapped Solar Market: The Renewable Potential of Multi-family Housing

North American Clean Energy, Sept./Oct. 2014, by Zach Axelrod.
http://www.nacleanenergy.com/articles/18582/an-untapped-solar-market-the-renewable-potential-of-multi-family-housing

"Solar energy is rapidly becoming a popular option for homeowners as a way to save money. But, what about folks who live in apartments or condos? Multi-family dwellings, as they are known, are providing the next potential growth opportunity for the residential solar industry. Now, innovative financing mechanisms allow even low-income families to take part in the benefits of solar power."

Financial Impacts of Net-Metered PV on Utilities and Ratepayers: A Scoping Study of Two Prototypical U.S. Utilities

Lawrence Berkeley National Laboratory, Sept. 2014, by Andrew Satchwell, and others.
http://emp.lbl.gov/sites/all/files/LBNL%20PV%20Business%20Models%20Report_no%20report%20number%20(Sept%2025%20revision).pdf

"A new report from Lawrence Berkeley National Lab (LBNL) that examines the potential impacts of customer-sited photovoltaics (PV) on electric utility profitability and rates. The report shows that these impacts can vary greatly depending upon the specific circumstances of the utility. The report also examines measures that could be pursued by utilities and regulators to mitigate the financial impacts."

Minimizing Risks with Solar Roofs

The Construction Specifier, Aug. 2014, by Michael Russo.

Reducing Costs of Residential Solar PV: Through Module & Hardware Innovations

North American Clean Energy, Jul/Aug 2014, by Tom Hood & Sicco W.T. Westra.
http://www.nacleanenergy.com/articles/18223/reducing-costs-of-residential-solar-pv-through-module-hardware-innovations

"To make life easier for solar system owners, several companies are working to lower BoS [Balance-of-System] costs and simplify racking designs and installation efficiencies. For instance, cost-competitive, roof-mounting brackets are one option now available to installers that can accommodate different types of rail supports for solar modules. Support rails with built-in wire clips are another example of a simplified BoS design, which lowers the cost of hardware and installation by five to ten percent."

How Solar Energy Trackers Stack Up: Evaluating Utility-Scale Success

North American Clean Energy, Jul/Aug 2014, by Jay Johnson.
http://www.exosun.net/images/download/press-articles/NACE_201407.pdf

"In terms of photovoltaic's (PVs), solar trackers--motorized structures that shift the position of modules--can significantly increase the production of utility-scale plants by optimizing the angle of incidence between a module and incoming solar rays."

Corrections Needed for PV Performance Blind Spots During Commissioning

Solar Industry, July 2014, by James Mokri & Joseph Cunningham.
http://www.solarindustrymag.com/issues/SI1407/FEAT_04_Corrections-Needed-For-PV-Performance-Blind-Spots-During-Commissioning.html

"If a photovoltaic system is commissioned according to industry standards, then it must be performing as expected, right? Not necessarily. PV industry standards for commissioning do not include performance testing.

NEC code and IEC 62446 mention nothing about performance testing. ASTM E2848-11 outlines a method of performance measurement during the commissioning stage, but it is not a complete, consistent, standardized method of measurement and metrics."

Micro-Inverters are Moving Up to the Big Leagues: Opinions Differ on the Future of AC modules in Large PV Installations

Solar Industry, Feb. 2104, by Michael Puttre.
http://www.solarindustrymag.com/issues/SI1402/FEAT_03_Micro-Inverters-Are-Moving-Up-To-The-Big-Leagues.html

"The potential of the micro-inverter segment is drawing interest from established powers in the string and central inverter markets."
