SRCC Overview - P. 1

OVERVIEW OF THE SRCC

The modern solar industry was founded in 1974, following the original oil embargo of the previous year.In the years which followed, energy in all its forms became a national priority. While commercial andresidential solar systems were available on a limited regional basis, a mechanism had to be put in placewhich would encourage consumers to purchase these relatively unknown products and new technologywith confidence that the technology was valid and that the products would perform in terms of energy anddollar savings.

States with potentially large solar markets, such as California and Florida, were the first entities toestablish such a mechanism by establishing state testing and rating programs for solar collectors.However, since there was little consistency between each states testing requirements and approach torating solar equipment, such programs soon became an impediment to manufacturers who marketed inmore than one state. The need for a single national program which manufacturers could test theirequipment to and which would benefit consumers by providing a uniform, national approach for rating andcomparing solar equipment soon became evident. In an unprecedented move, the trade association forthe solar energy industry and a national consortium of state energy offices and regulatory bodies joinedtogether to lay the groundwork for such a program which would soon lead to the founding of the SolarRating and Certification Corporation.

The Solar Rating and Certification Corporation (SRCC) is an independent third-party certificationorganization that administers national certification and rating programs for solar energy equipment. TheSRCC was incorporated in October 1980 as a non-profit corporation. It is governed by a twelve-memberBoard of Directors with representation from the public, private, and generalist sectors.

The combined programs of the Solar Rating and Certification Corporation provide one-time certification,national recognition, product credibility, and standardized comparisons of solar energy products. TheSRCC programs serve three primary constituencies: the solar energy industry, solar consumers, andstate and federal regulatory bodies. All three constituencies benefit from the SRCC programs byobtaining a national state-of-the-art rating system, a mechanism to develop consumer confidence, and arational and defensible criteria for tax credit qualification and other solar incentive programs.

Solar equipment manufacturers benefit from SRCC certification and rating in three fundamental ways:the ability to have a product certified only once; national recognition and/or reciprocity of the certification;and a reliable means for judging product durability and performance on a relative standard basis. Thesolar contractor benefits from the SRCC certification in three fundamental ways also: certification

provides product credibility; provides one with a standard of comparison to be used in sales literature;and provides a defense against unethical competition and false claims. The solar consumer also benefitsfrom the SRCC programs. These benefits include obtaining a measurement of quality, a measurement ofperformance, third-party independent corroboration, and a national standardized method to comparesolar equipment and thereby determine the best buy. Finally the government and states benefit fromSRCCs programs in that certification provides a rational basis for tax credit qualifying regulation as wellas a basis for setting codes and standards.

SRCC Overview - P. 2

The corporation is governed by a twelve-member Board of Directors comprised of solar experts from boththe public and private sectors. Four members of the board represent the solar energy industry, fivemembers represent the public sector, and three members represent general interests (utilities, solutions,research, building industry, etc.). Adding to the governance of the corporation are a variety of standingand ad hoc committees. Committee members are appointed by the Board of Directors and arerepresentatives from the industry sector, state and federal agencies, consumer organizations, andacademia. A sampling of these committees and their respective purposes is as follows:

Technical Compliance Committee. Acts in a technical oversight capacity with respect to theprograms in SRCC in order to insure that technical matters addressed in the program have beenappropriately resolved and reviews the technical decisions made by SRCC program administrators toinsure the accuracy of the test results and the appropriateness of the assigned ratings.

Design Review Committee. Reviews applications for certification for compliance with theappropriate requirements.

Consumer Advisory Committee. Enables the SRCC to more fully serve its consumerconstituency by making available the programs to the solar consumer buyer and user in a moredirect and understood manner and governs the presentation, interpretation, publication, and useof the performance information.

Laboratory Accreditation Committee. Oversees the SRCC laboratory accreditation program andinsures that accredited test facilities continually meet the criteria for accreditation.

The Solar Rating and Certification Corporation currently administers a certification, rating, and labelingprogram for solar collectors and a similar program for complete solar water and swimming pool heatingsystems. SRCCs certification program operating guidelines, test methods and minimum standards, andrating methodologies require the performance of nationally accepted equipment tests on solar equipmentby independent laboratories which are accredited by SRCC. The test results and product data areevaluated by SRCC to determine the products compliance with the minimum standards for certificationand to calculate the performance ratings. Equipment which has been certified and rated by SRCC isrequired to bear the SRCC certification label which shows the performance rating for that product. Inaddition, each certified product is published by SRCC in a directory. Each products directory listing

contains information on the products material and specifications as well as the certified thermalperformance rating.

THE SRCC SOLAR DOMESTIC HOT WATER SYSTEM CERTIFICATION PROGRAM

Solar water heating systems are composed of a number of components. All of these components mustwork together for the system to collect and deliver the maximum amount of heated water. The purpose ofthis solar water heating system certification and rating program is to improve performance and reliabilityof solar products. It integrates results of collector tests and system tests with evaluations againstminimum standards of system durability, reliability, safety and operation; as well as factors affecting total

system design, installation, maintenance and service. Giving suppliers the opportunity to submit theirsolar domestic hot water (SDHW) system designs to an open-ended review encourages them to producethe best products possible. The program is administered according to SRCC document OG300,Operating Guidelines and Minimum Standards for Certifying Solar Water Heating Systems.

Under the OG300 system rating and certification program:

Systems must meet or exceed all criteria required to meet HUD Minimum Property Standards.

Rating includes a simple way for consumers to compare expected performance and energy savings.

Unique features of this certification program include:

Evaluation of system design, safety, installation procedures, operation and maintenance manuals andsystem performance.

Rating label that is comparable to the Energy Guide Label required by the Federal Trade Commissionfor most gas and electric hot water heaters.

The process for rating and certifying solar water heating systems under the OG300 protocol includes tensteps for each system. The process is described below and illustrated in Figure 1.

1. The Supplier of a solar water heating system is the entity responsible for the assembly andinstallation of the system. The first step in the certification process is for the Supplier to decide whichcomponents are to be included in the system. These components must be listed on an OG300application form.

2. The solar collecting portion of the system must be tested. The testing to be done is determined bythe system design:

a. The collectors which are part of the system must be tested and rated under the OG100 protocol.

b. Passive systems in which the collector can not be tested separately must be rated and certifiedunder a system test protocol.

3. A diagram must be prepared showing the relative location and interconnection of all systemcomponents.


5/33

OG300 Overview P.2

4. Manuals must be written to describe installation, operation, and maintenance of the system. Themanuals must include a copy of the system diagram as well as all information required in section 6.6of the OG300 document.

5. Labels must be prepared in accordance with OG300. A summary of the required labels is attached tothe application form.

6. The application and all supporting documents are reviewed by SRCC staff and then forwarded to the

SRCC Design Review Team for review and discussion. Major system components, the contents ofthe manual delivered with the system, and the suppliers instructions for system installation must beapproved by SRCC

7. Data from the OG100 collector test, the system test and review of design and installation guidelinesare input to a computer program called TRNSYS to calculate the performance rating.

8. When all reviews have been completed, SRCC will notify the applicant of any outstanding items to besubmitted.

9. When the application is complete and all fees have been paid, SRCC will finalize the performancerating, prepare a new page for the directory, and mail the program agreement and/or license(s) to theSupplier for signature.

10. Upon receipt of the signed document(s) SRCC will prepare a certification award and rating labelartwork and will publish the directory pages.

Figure 1 SRCC OG 300 Test and Certification Process

Major system components, the contents of the manual delivered with the system, and the suppliersinstructions for system installation must be approved by SRCC. Certification is based upon thedetermination by SRCC that the system successfully meets its minimum criteria for design, reliability anddurability, safety, operation and servicing, installation, and operation and maintenance manuals.

Tables 1-6 summarize the features evaluated for each of the six major criteria during system certificationunder the OG300 protocol. Most of those features are self-explanatory. Obviously, some of the featureswill not be applicable to certain systems.

OG300 Overview P.4

The thermal performance rating is based on performance projections derived from the design of thesystem and from testing of the collector components used in the system, or from testing and evaluation ofthe system as a whole, as shown schematically in Figure 1.

Most rating programs require the equipment to be tested in accordance to a standard test with specifiedtest conditions. This provides a repeatable performance within an accepted uncertainty band. There are,however, some rating programs which combine a standard test and a calculation procedure to produce aperformance rating. Such is the case for the energy guide label for electric and gas residential hot water

heaters. SRCC has adopted a similar method to develop a consumer friendly, practical system rating.The intent is to present to consumers an easily understood comparison between SDHW systems andconventional hot water systems. Note that the performance any individual consumer will experience maydiffer due to location and hot water usage.

SRCC uses the Solar Energy Factor (SEF) as its performance rating for solar domestic water heatingsystems. The SEF is defined as the energy delivered by the system divided by the electrical or gasenergy put into the system.

Every SRCC OG300 certified, solar water heating system should bear a label similar to this:

AWWA Heat Exchanger Types:

SW (single wall with no leak detection):Provides a single wall separation between the transfer medium and potable water. Failure of this wallwill result in the mixing of the potable water and transfer medium.

DW (double wall with no leak detection):Provides two distinct walls which separate the transfer medium from the potable water. Contaminationof the potable water from a non-potable heat transfer medium would require an independent failure ofboth walls.

DWP (double wall with leak detection):Provides two distinct walls which separate the transfer medium from the potable water and a path toatmosphere. Failure of either wall is indicated by visual leakage of the transfer medium or potable waterand indicates a failure of the heat exchanger. The DWP type provides a higher degree of protection than

the SW or DW types.
