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

North American Clean Energy, Jul/Aug 2014, by Tom Hood & Sicco W.T. Westra.

"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."

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."
