Analysis indicates the U.S. can reduce solar PV costs through installation labor efficiency.

Snowmass, Colo. (PRWEB) July 15, 2014

Rocky Mountain Institute (RMI) released a report today with Georgia Tech Research Institute (GTRI), Lessons from Australia: Reducing Solar PV Costs Through Installation Labor Efficiency, identifying on-the-ground opportunities for the U.S. market to reduce solar photovoltaic (PV) system costs and accelerate residential and commercial customer adoption. As a result of not implementing these best practices, the report concludes the U.S. continues to lag behind global PV leaders Germany and Australia in prices for residential installations.

With solar module costs relatively the same everywhere, total soft costsincluding customer acquisition, installation labor, permitting, inspection and interconnectionnow comprise approximately 70 percent of the total installed price for a U.S. residential PV system, making soft costs a prime opportunity for drastic cost reductions.

After examining Germanys installation labor practices and releasing the results in a December 2013 study, RMI and GTRI traveled to Australia this past spring to analyze the varying PV installation processes of that country. Each provided a unique opportunity to draw a comparison between installation costs and methods; when combined with the U.S., the three countries comprise more than 39 percent of total global distributed PV generation.

In particular, Australia has emerged as a dominant player in the world residential solar market, with more than 10 percent of households possessing a rooftop solar system with costs of $2.56/W, closely rivaling Germanys $2.21/W (compared with $4.93/W in the U.S.). Without using advanced technologies or processes, Australian installers can install solar systems in less than two-thirds the time per kW than U.S. installers.

RMIs work in Australia diversifies our understanding of how the cost of installed solar PV systems can be competitively reduced, said Karen Crofton, a principal at RMI. The observations gleaned from Australia will help U.S. solar providers streamline their installation processesstarting today. If it can be done in Australia and Germany, there is no reason it cannot be done in the U.S.

Using time-and-motion methodologies, several cost-reduction opportunities were identified during observations in Australia:

  •     Pre-installation and base-installation process optimization
  •     Integrated racking and mounting solutions
  •     PV meter integration

Lessons learned from these leading markets in Germany and Australia are formative for advanced residential and commercial PV racking technologies currently under development, said GTRI Senior Research Engineer Joseph Goodman. Ultimately, we are looking to not only leapfrog best-in-class U.S. systems, but also surmount these global benchmarkshelping us reach the Department of Energy SunShot cost reduction targets.
