Background Program Goals IndustryCollaboration FutureCollaborations Publications Contacts   Photovoltaic (PV) arc-faults can lead to fires, damage property, and threaten the safety of building occupants. In response, Article 690.11 was approved for the 2011 National Electrical Code®, requiring new PV systems, 80 V or greater, on or penetrating a building to include a listed arc-fault protection [...]


Past Market Transformation Activities

On April 4, 2012, in

Current activates have built upon past efforts, most notably the Solar American Cities (now Communities) program in recent years. Solar American Cities Sandia provided technical assistance to U.S. cities, nongovernment organizations, and federal facilities that won awards for our services, which included facilitating solar site selection and optimization; providing systems performance projections; identifying and quantifying [...]


Siting

On April 4, 2012, in

At the residential and commercial levels, poorly sited projects can result in reduced system performance, among other things; while at the utility scale, where a project is sited may result in increased costs associated with access to transmission, environmental impacts, and other potential conflicts. Water Availability Water availability is a critical issue with the potential [...]


Installation

On April 4, 2012, in

Workers who install systems have a critical role in reducing both the upfront and the lifecycle costs of PV systems. Labor costs represent a significant portion of total system costs. And although the effect is not observed in upfront $/watt costs, subpar installation practices increase cost by limiting system performance, effectively increasing the system levelized [...]
