Request for Information for Photovoltaic Community Project: 
Fielded Photovoltaic Systems and Components Data

AGENCY: Office of Energy Efficiency and Renewable Energy, Department of 
Energy.

ACTION: Request for Information (DE-PS36-09GO39002).

-----------------------------------------------------------------------

SUMMARY: The Department of Energy (DOE) today gives notice of a Request 
for Information (RFI) to invite comment on approaches to address the 
need for consistently-collected reliability data of fielded 
photovoltaic systems, data analysis to deduce methods for assessing 
reliability and to improve accelerated aging tests to create predictive 
models, improvement in existing tests, more information on best 
practices for reliability and accelerated aging tests, and assessing 
the nature and frequency of safety-related issues (arcing, building 
integration aspects, and ground faults) and their relationship with 
long-term performance. It is clear that the foundation to address these 
needs is a database consisting of photovoltaic system and component 
reliability, as well as performance data, which are collected in a 
consistent manner. In addition to the database, it is necessary for DOE 
to collaborate with the national laboratories and others to evaluate 
the data, develop new or modified tests, assess safety, evaluate system 
and component interactions, and develop predictive models.
    DOE is issuing this RFI for information and feedback from the PV 
community stakeholders. These include, but are not limited to, system 
operators and integrators, utilities, project planners, financial 
planners, manufacturers, third-party data-aggregation companies, 
universities, testing facilities, and other interested parties.
    See the SUPPLEMENTARY INFORMATION section of this document, which 
provides further detail and comments requested.

DATES: Written comments must be received by 11:59 p.m. Eastern Time on 
December 17, 2008.

SUPPLEMENTARY INFORMATION: A major emphasis of the Department of Energy 
Solar Energy Technology Program (SETP) is achieving cost 
competitiveness and broad commercialization of solar electric 
technologies in the United States. The SETP is focusing primarily on 
two areas: (1) Research and development (R&D) on photovoltaic (PV) 
component and system designs, including low-cost approaches for 
manufacturing them; and (2) technology acceptance activities that 
address marketplace barriers and offer the opportunity for market 
expansion. Key elements in the market transformation are the ability to 
evaluate the performance and reliability of solar products and systems.
    As noted in the SETP Multi-Year Program Plan \1\, system 
integrators, project planners, and the financial community need more 
rigorous data about overall system performance. System reliability, 
including service life prediction, is also essential for investment 
decisions. Manufacturers are also seeking techniques for quantifying 
the performance and reliability of their products and systems. During 
the Second Accelerated Aging Workshop (April 1-2, 2008) \2\ specific 
needs were identified. These inter-related needs include the following:
---------------------------------------------------------------------------

    \1\ SETP Multi-Year Program Plan 2008-2012; https://
www1.eere.energy.gov/solar/pdfs/solar_program_mypp_2008-2012.pdf.
    \2\ Proceedings reported in ``Accelerated Aging Testing and 
Reliability in Photovoltaics Workshop II Summary Report'' are found 
at: https://www.eere.energy.gov/solar/solar_america/pdfs/
accelerated_aging_report_2008.pdf.
---------------------------------------------------------------------------

     Consistently-collected reliability data of fielded 
systems;
     Data analysis to deduce methods for assessing reliability 
and to improve accelerated aging tests to create predictive models;
     Improve existing tests and provide more information on 
best practices for reliability and accelerated aging tests;
     Assessment of the nature and frequency of safety-related 
issues (arcing, building integration aspects, and ground faults) and 
their relationship with long-term performance.
    Based upon these insights, there is a clear need for data to 
accomplish the following:
    1. Document degradation rates for PV systems and components 
deployed in different climates/configurations:

--With the recent advances and the proliferation of module 
manufacturers, information is needed to (1) update understanding of 
degradation and failure rates; (2) link degradation to use 
environments, and (3) define specialized, feasible measurement 
approaches to the degradation rates for emerging technologies.

--Minimal data is available on degradation and failure rates for other 
PV system components, such as inverters, wiring, trackers, etc.

    2. Document failures observed for PV systems and system components 
deployed in different climates/ configurations:

--Documented, consistent data about system/component performance, 
maintenance events, and the related cost will establish an 
understanding about deployed systems or components. System components 
would include all elements of the system.

    3. Define ``use conditions'':

--Data may support further categorization of PV system or system 
component degradation according to ``use conditions,'' which may differ 
from the climate zones defined in existing standards such as IEC 60721.

    4. Establish technical basis for testing methods and codes and 
standards.

--Data collected from fielded systems by a consistent method may 
improve understanding of use conditions for systems and/or components.

--Consistent data can support the development of appropriate codes and 
standards for the industry.

Proposed Strategy

    The intent of this RFI is to invite comment on approaches to 
address the needs described above. The foundation to address these 
needs is a database consisting of photovoltaic system and component 
reliability data, as well as performance data, which are collected in a 
consistent manner. In addition to a database, it is necessary for DOE 
to collaborate with national laboratories and others to evaluate the 
data, develop new or modified tests, assess safety, evaluate system and 
component interactions, and develop predictive models. The following 
describes a possible approach.
    Other ideas are encouraged.

Proposed Topic

    Consistently collect performance and reliability data about fielded 
systems and their components, in a range of locales over an extended 
period of time. Large and small systems would be of interest.
     To develop or verify predictive performance and 
reliability models to better understand system and component 
interactions in collaboration with the national laboratories and 
others;
     To evaluate module degradation and failure rates of 
fielded modules in a range of use conditions in collaboration with the 
national laboratories and others.

Proposed Tasks To Accomplish This Topic Are:

    Task 1: System Selection: Systems must be fielded and commercially 
available. Small-scale systems based on prototypes would be optional. A 
range of technologies, system sizes, and diverse locales are required. 
It is also desirable that system owners and site operators will be 
willing to provide access to research teams to permit on-site 
measurements. It may be desirable to swap out components for detailed 
laboratory characterization. In these cases, arrangements for spare 
components would be necessary to minimize impacts on system operation.
    Task 2: Data Monitoring: Use standardized methods for all sites to 
collect information about system and component performance, 
reliability, and maintenance.
    Task 3: Database: Establish and maintain database.
    Task 4: Data Analysis and Reporting. Conduct data review, and 
periodic consolidation, analysis and reporting of the findings, 
recommendations and next steps.

Approach

    Three alternative approaches have been identified.

Alternative 1: Funding Opportunity Announcement (FOA) (for Grants or 
Cooperative Agreements)

    DOE could issue a competitive FOA for applications, with Applicants 
providing access to their deployed

[[Page 74479]]

systems and components to collect performance, reliability, and 
maintenance data according to established protocols. Such a FOA may 
involve system integrators, operators, or others offering access to 
systems, possibly a third party for data collection and aggregation, 
and collaboration with the national laboratories and others for 
testing, and the national laboratories for data analysis and storage, 
all accomplished in a consistent, coordinated project.

Alternative 2: Non-Competitive Collaborative R&D

    The national labs could negotiate individual, non-competitive 
arrangements with selected participants (companies, test labs, and/or 
universities) regarding the relative roles and commitments of the 
various parties to achieve the stated objectives. Negotiations would be 
on a case-by-case basis, with the national laboratories in the lead 
coordinating role, based upon their planned work for the DOE SETP in 
their Annual Operating Plans.

Alternative 3: DOE/SETP Acquisition

    A DOE acquisition process could be used to acquire access to PV 
systems for the purpose of installing data collection equipment, 
collecting system performance, reliability, and maintenance data, and 
monitoring the system. An acquisition could include services to 
implement the data collection. Data could be collected by a site 
custodian, a third party, a national laboratory team, or a combination 
of options.
    In all cases the data collected would be analyzed to establish 
capabilities by a national laboratory team, in which DOE has already 
invested. Opportunities would exist for additional collaboration with 
other testing facilities to participate in achieving the common goals. 
Results would be made public in a summary form that would not be 
identifiable by system or manufacturer. Participants in the project 
would be given the summary information, along with their particular 
system/component data. This would offer them the benefit of knowing how 
their specific use condition compares with others under a particular 
set of criteria. Those not in the program will have access to the 
summary public information.

Request for Information Guidelines

    Respondents are asked to specifically comment on the above proposed 
strategy, and the questions below. Respondents are free to comment on 
the general concept, potential benefits or obstacles, the overall 
merits of this idea, other alternatives, and the relative priority of 
this activity.
    DOE will evaluate responses to this RFI to determine the best 
approach to move forward. If a FOA or an acquisition process is 
warranted, DOE would formulate the content based on these comments and 
program needs. DOE may determine that a FOA or an acquisition process 
is NOT needed, and that companies will make individual arrangements 
with the national laboratories.

Questions

    (1) Motivation: Would industry be willing to participate in such a 
program and what would participants expect or require? In addition to 
the benefits mentioned, are there other useful financial and/or project 
outcomes?
    (2) Requirements: Are there any special requirements or 
considerations an entity must have in order to participate?
    (3) Needs: Are the stated needs appropriate? Is the list complete, 
or are there additional needs? What additional needs could be addressed 
by a consistent performance and reliability database? How long should 
the data collection project last, e.g., 1 year, 5 years, other?
    (4) Priorities: Are there other priorities instead of, or in 
addition to, those identified? How would they be ranked?
    (5) Data: What are specific suggestions about what data is needed? 
A continuous data stream consolidated into specific intervals is 
envisioned. Is this appropriate? Suggestions about the data collection 
instrumentation and methodology are welcomed.
    (6) Topic: Is the topic appropriate? Are there other topics that 
should be included and why?
    (7) Tasks: Are the tasks appropriate? Are there other tasks that 
should be included and why?
    (8) Critical Milestones: What critical milestones are recommended 
to measure the success of this effort and why?
    (9) Approach: Of the Alternatives to implement this effort, is 
there one that would be the most useful? Are there other, more 
expedient approaches to achieving the objectives? Please describe.
    (10) Confidentiality: DOE has procedures for maintaining data 
confidentiality, and creating a firewall so the data is not subject to 
the Freedom of Information Act (FOIA). Is this essential? Are there 
specific concerns that could be addressed on an individual basis?
    (11) Costs: What would be the estimated costs of the different 
alternatives?
