OG-100 Program
  • SRCC OG-100 certification program is for solar thermal collectors to the requirements contained within OG-100 Operating Guidelines, which references ICC 901/SRCC Standard 100. SRCC now also offers optional listings to several specific extra standards under OG-100 at the request of the participant.

    Listings to codes and standards involves assessing a product or system’s compliance with the relevant requirements of one or more specific model plumbing, mechanical, building codes and/or standards adopted by jurisdictions around the U.S. Unlike the SRCC certification programs, SRCC’s listings do not result in a performance rating. Listings are optional, but can facilitate acceptance in many jurisdictions. Listings are valid for a period of 1 year and may be renewed annually. See the Listing Program webpage for more information.

  • Yes, but SRCC must be notified in advance. SRCC will evaluate the change to the collector to determine continued compliance and whether retesting will be required before revising the certification. Editorial or technical modification fees may be assessed.

  • Yes, they must be registered with SRCC so you can login and authorize a Private Label to that company.

  • Yes, once you have OG-100 certification, you may login to your account and apply for a Private Label.

  • Yes, SRCC staff can assess the test report to determine whether it can be used for OG-100 certifications. Testing conducted for other certification programs like Solar Keymark, may be applicable for OG-100 certification. In some cases the testing will meet most, but not all, SRCC requirements. In this case a gap report addressing the remaining testing requirements will be accepted. For a FREE review of your existing test report, please send the document to SRCC at srcc@solar-rating.org We will follow up shortly with our assessment of the data.

  • No. The application material and test results must be reviewed by SRCC staff and the ratings will be calculated. Once all requirements for the OG-100 program are met, including receipt of the signed program agreement, program fees, and all requested product documentation, SRCC will award certification.

  • Testing requirements for each type of collector is established in the ICC 901/SRCC 100 Solar Thermal Collector Standard which is available for viewing or purchase on the ICC-SRCC standards page. We encourage you to talk with us prior to testing. ICC-SRCC staff would be happy to answer any questions and explain the testing requirements for your particular type of product.

  • The process time will vary with each application. The timeframe for testing is generally 2-6 months. This is something manufacturers should discuss with the approved SRCC test labs that you are considering.The test results are evaluated in the order in which they are received. Certification is usually awarded in approximately 3-4 weeks (unless additional information is needed).

  • Yes, there is an annual fee required in order to renew collector certifications. If changes are made to the certification, they may result in Editorial or Technical Modification changes. Inspection and self assessment fees are also incurred during the period of certification.

  • SRCC OG-100 certifications are valid for a period of one year and are eligible for renewal annually. The test reports submitted for the certification of collectors are valid for a period of 10 years from the date of issuance of the report. After that time period elapses, the manufacturer must submit a new test report in order to continue certification of the collector.

    OG-100 certification holders must also notify SRCC of any design changes to the collectors and comply with all inspection, SRCC staff will remind you of an upcoming renewal to help you ensure that there is no gap in your coverage.

  • ICC SRCC has a specific mark used to convey OG-100 certification (specific usage is established in the Rules for Certificate and Mark Use found in the Policy Section.

    SRCC also issues a separate certification document that is available for viewing on the SRCC website. Up-to-date OG-100 certificates can be found using SRCC’s searchable online directory.

  • While obtaining an OG-100 certification from SRCC (or any other qualified certification body) is not mandated at the national level, it is required by incentive programs, building codes and other regulations in dozens of states. Therefore, in order to install or qualify for vital solar thermal incentives, an OG-100 certification is required in most locations in the U.S.

    Just a few examples of incentives programs specifying OG-100 certification include:

    There are too many other programs and regulations which prescribe OG-100 to list here. See the Database of State Incentives for Renewables & Efficiency (DSIRE), which is produced by NC State University for the U.S. DOE.

    Several model codes now also require compliance with SRCC Standard 100. These include:

    • 2015 & 2018 International Residential Code (IRC)*
    • 2015 Uniform Solar Energy and Hydronics Code (USEHC)**
    • 2018 International Building Code (IBC)*
    • 2018 International Plumbing Code (IPC)*
    • 2015 & 2018 International Mechanical Code (IMC)*
    • 2018 International Swimming Pool and Spa Code (ISPSC)*

    • *Copyrighted publication of the International Code Council (ICC)

    • ** Copyrighted publication of the International Association of Plumbing and Mechanical Officials (IAPMO)

    For jurisdictions that have adopted these model codes as the basis for their state or local code, compliance with Standard 100 will likely be required. Check with your local jurisdiction for details.

    The 2015 IRC, for example, and requires third-party certification to reference standards:

    • P2609.4 Third-party certification. Plumbing products and materials required by the code to be in compliance with a referenced standard shall be listed by a third-party certification agency as complying with the referenced standards. Products and materials shall be identified in accordance with Section P2609.1.

    Simply put, OG-100 certification is the best way to ensure that your solar thermal collector will meet local regulations and incentive program requirements anywhere in the U.S.

  • OG-100 certifications are based on the ICC 901/SRCC 100 Solar Thermal Collector Standard which is available for viewing or purchase on the ICC-SRCC standards page. This ANSI standard sets the technical requirements for these collectors and references many other specific standards. ICC 901/SRCC 100 in turn references the internationally-accepted ISO 9806 Solar Energy – Solar Thermal Collectors –Test Methods standard. This is the same testing standard utilized by other notable international certification programs, including the European Solar Keymark Program, with minor testing variations.

  • SRCC’s OG-100 certification program refers to the Operating Guidelines associated with the SRCC Solar Thermal Collector Certification Program. The Operating Guidelines (OG) refer to the requirements, policies and procedures associated with the certification program, and are specific to SRCC. The OG-100 document references the SRCC Standard 100 document (ICC 901/SRCC 100), which sets the technical requirements for the evaluation and rating of solar thermal collectors. SRCC Standard 100 is a generic standard for these collectors that is produced by SRCC but does not specifically require that certification to the standard be conducted by SRCC. The current version of Standard 100 is known formally as ICC 901/SRCC 100 Solar Thermal Collectors, and it was approved by ANSI as an American National Standard in 2015. It is currently set to be revised starting in 2019.

  • Yes, dozens of incentive programs around the U.S. specify, accept, and recognize SRCC’s OG-100 certifications. In fact, some incentive programs accept SRCC’s certifications for solar thermal collectors exclusively. SRCC was created by a group of states, SEIA and the Federal Government in the 1980’s to address the need for quality and performance certification for solar thermal collectors and systems. SRCC has been recognized as the preeminent organization for solar thermal certification and rating for decades. To see incentive programs for selected locations, visit the Database of State Incentives for Renewables & Efficiency (DSIRE) for listings of solar water heating and solar pool heating programs.

  • Yes, most code officials accept SRCC OG-100 certification as proof of compliance with SRCC Standard 100. SRCC is accredited by the American Association for Laboratory Accreditation (A2LA) to ISO/IEC Standard 17065, Conformity assessment - Requirements for bodies certifying products, processes and services, for the certification of solar heating and cooling equipment. Code officials use SRCC OG-100 certification documents to inspect the installed systems to ensure that the collector meets all requirements in the standard. As a member of the International Code Council Family of Companies, SRCC is backed by the largest association of building officials in the country. Code officials know and trust the ICC name.

    Note: Many codes have other requirements above and beyond OG-100 compliance. OG-100 only provides assessment to the ICC 901/SRCC 100 standard. For evaluation to all of the requirements in various codes and standards see the SRCC Codes and Standards Listing Program.

  • SRCC provides several certification programs for solar thermal products, including OG-100 and OG-300. The OG-100 program provides for certification of solar thermal collectors, and requires compliance with the ICC 901/SRCC 100 Solar Thermal Collector Standard. OG-100 certification requires a range of laboratory tests to assess the safety, durability and thermal performance of each collector. The OG-300 certification program addresses solar thermal systems and requires compliance with the ICC 900/SRCC 300 Solar Thermal System Standard. For OG-300 certification, the use of an OG-100 certified collector is required. Using information on the other system components, including the tank, pump, heat exchanger, controller, piping and valves, the system is modeled to determine performance. SRCC staff also reviews the components, system design, and manuals to ensure that they meet the minimum requirements of the standard. In most cases, testing of the entire system is not required by the ICC 900/SRCC 300 Standard. However, testing of individual components may be necessary to provide the information needed for the computer model of the system.

    OG-300 certification addresses the entire system, whereas OG-100 certification only covers one part of that system – the collector. OG-100 does provide collector rating information, which allows specific collectors to be compared. However, OG-100 does not provide all of the information needed to describe the performance of the system. OG-100 does not address the other system components that can have a very significant impact on performance, like tanks, pumps, heat exchangers and controls. For example, a collector with a high OG-100 rating paired with a low-quality or poorly matched controller could achieve a low OG-300 rating. OG-100 alone is simply not an adequate predictor of system performance.

    1. First-time applicants should start by registering with SRCC. This is a simple, one-time process that establishes the necessary company contact and user information on the SRCC website. There is a $500 registration fee. Go to Register Now at https://secure.solar-rating.org/ SRCC participants seeking certification for additional products can skip this step.
    2. Next, you will need to have your product tested in accordance with SRCC’s requirements by a SRCC approved testing laboratory. SRCC does not provide product or laboratory testing services. Manufacturers seeking new testing services to support SRCC OG-100 certification must independently select from among the SRCC Approved Testing Programs and contract directly with the testing laboratory to conduct the required testing. Please note that lab fees and schedules are separate from those associated with SRCC certification.
    3. After scheduling laboratory testing, apply for SRCC OG-100 Certification on the SRCC website. Login at https://secure.solar-rating.org/ and go to the My Options menu, choose View/Create/Modify Package and click on the Create New Package button. The automated system will take you through the application process, including an invoice and a credit card payment screen. If you choose to pay the certification fees by check or wire transfer, close the credit card window and we will let you know when we receive payment. The Basic collector is the tested collector. If you would like to apply for any Resizes, choose the Add Request to This Package button after completing the information for the Basic collector. There is a section where you will be asked to upload related documents such as drawings. Once completed, be sure to click Finalize Package.

See the DSIRE Website for information on incentive programs in specific locations around the U.S.
    • CODE COMPLIANCE. Several model building codes require installed systems to comply with SRCC Standard 100 (the standard that provides the technical basis of the OG-100 program). Therefore, by certifying your system to OG-100, you are demonstrating compliance with SRCC Standard 100 and meeting one of the key requirements of these codes. Examples include the IAPMO Uniform Solar Energy Code and the ICC International Residential Code (IRC). Note: Many codes have other requirements above and beyond OG-100 compliance. OG- 100 only provides assessment to the ICC 901/SRCC 100 standard. For evaluation to all of the requirements in various codes and standards see the SRCC Codes and Standards Listing Program.
    • SAFETY AND DURABILITY. OG-100 certification addresses more than just ratings. During the course of certification, SRCC’s engineers review the design and construction of the collector to be sure that they comply with the minimum requirements set in the ICC 901/SRCC 100 Standard. This provides users with assurance that the collector meets the standard’s comprehensive requirements for safety, durability and minimum performance.
    • WEB-BASED CERTIFICATES. All collectors certified under the OG-100 program are provided with an OG-100 certificate and are listed on the SRCC website, www.solar-rating.org. The certificates provide tables featuring rated performance under standardized climate conditions and applications. Detailed performance data is also provided to allow system designers to model the collectors as part of a system. Code officials and incentive programs recognize SRCC’s website as the authoritative source of up-to-date information on OG-100 certified collectors. They use the certificates there to verify certification, and to confirm that systems are installed in compliance with the certification. This results in faster, streamlined inspections.

  • Yes, OG-300 may be applied to commercial systems, but many of these larger systems are unique and specifically designed for the application. Therefore, it is most commonly specified for residential domestic water heating systems by incentive programs. Many incentive programs require the use of OG-100 certified collectors for commercial systems, and then evaluate the balance of the system by a variety of means. They may also require the use of a heat meter to measure actual system output instead of using the modeled performance to determine incentives.

  • OG-300 certification is available for most solar thermal systems used to heat fluids such as water, glycol or air. It addresses systems used for heating, cooling, dehumidification and co- generation. While it may be used for commercial systems, many larger systems are unique and specifically designed for commercial application. Therefore, it is most commonly specified for residential domestic water heating systems by incentive programs. It does not apply to utility-scale systems or solar pool heating systems (see the OG-400 program which references ICC/APSP 902/SRCC 400 Solar Pool and Spa Heating Systems for certification of solar pool heating systems).

ICC-SRCC is also approved and accepted by the City of Los Angeles as a listing/certification agency.

    • CODE COMPLIANCE. Model swimming pool codes require installed systems to comply with ICC-SRCC Standard 400 (the standard that provides the technical basis of the OG-400 program). Therefore, by certifying your system to OG-400, you are demonstrating compliance with ICC-SRCC Standard 400 and meeting these codes.
      An examples is the 2021 International Swimming Pool & Spa Code (ISPSC). Note: Many codes have other requirements above and beyond OG-400 compliance. OG-400 only provides assessment to the ICC 902/APSP 902/SRCC 400 standard.
    • SAFETY AND DURABILITY. During the course of certification, ICC-SRCC’s engineers review the components and arrangement of the system to be sure that they comply with the minimum requirements set in the ICC 902/APSP 400/SRCC 400 Standard. This provides users with assurance that the system meets the standard’s comprehensive requirements for safety, durability and minimum performance.
    • WEB-BASED CERTIFICATES. All systems certified under the OG-400 program are provided with an OG-400 certificate and are listed on the ICC-SRCC website, www.solar-rating.org. The certificates provide the certified performance ratings for the system and a complete schematic of the approved system. Code officials and incentive programs recognize ICC-SRCC’s website as the authoritative source of up-to-date information on certified solar water heating systems. They use the information and certificates there to verify certification, and to confirm that systems are installed in compliance with the certification. This results in faster and more accurate inspections.

ENERGY STAR Program
  • ENERGY STAR certification demonstrates to potential customers that the product not only passes the minimum standards in OG-300, but it also meets performance criteria. The warranty requirements demonstrate that the product is well-supported by the manufacturer. Certification holders have the right to display the well-recognized ENERGY STAR label (in accordance with program brand requirements)

    Incentive programs in some states require ENERGY STAR certification to qualify for rebates. See the Database of State Incentives for Renewables & Efficiency® (DSIRE) for the latest information on incentives, rebates and tax credits.

  • The U.S. EPA sets the requirements for solar water heaters seeking certification under their Residential Water Heater Program as follows:

    • System must be OG-300 certified
    • Solar Energy Factor (SEF) > 1.8 for electric and > 1.2 for gas backup
    • Warranty provided must be: > 10 years for collector, > 6 years on sealed system, > 2 years on controls and > 1 year for piping and parts
    • Manufacturer must be an ENERGY STAR partner

Code Listing Program
  • Additional codes and standards can be added to an existing listing file at any time, but may incur fees for the change. Contact ICC-SRCC for details. Alternatively, additional codes or standards from the list of offerings in the ICC-SRCC Code Listing Guidelines can be added upon the renewal of a code listing.

  • You can obtain an ICC-SRCC Listing for any product that has an OG-100 or OG-300 certification (and certain commercial SHC components). Just go to the ICC-SRCC website to apply or e-mail srcc@solar-rating.org for more information. Be aware, though, that you can save money by applying for listings when you apply for your certification, where the application package fee is waived.

  • Application is easy. Simply fill out the online form or e-mail srcc@solar-rating.org.

  • The International Code Council (ICC) provides online access to its family of 15 model codes through the publicACCESS and premiumACCESS portals. ICC-ES and SRCC provide links to listings that pertain to specific sections of ICC’s codes. For examples, seethe green SRCC symbol in Chapter 23 of the 2015 IRC or Chapter 14 of the 2015 IMC. This feature places listings in front of millions of users of these online code portals. It’s a service that only ICC-SRCC and ICC-ES can offer.And of course, all listings are always provided on SRCC website’s directory as well.

  • New versions of the model codes are released every three years. New versions of standards are released periodically, but usually not on a predictable schedule. When any of the codes or standards to which ICC-SRCC lists solar heating and cooling products are updated, ICC-SRCC staff will review the new documents for changes impacting listings. Staff will then communicate a schedule to implement the new version of the code or standard in the ICC-SRCC Listing Program. After the effective date, all new listings and renewals will be done to the new code or standard version. ICC-SRCC will not require existing listing holders to update their listing to the new code or standard until the listing expires and is due for renewal.

  • Listings are valid for one year and will need to be renewed annually. Upon renewal, ICC-SRCC staff will confirm that there have been no changes to the product or associated manuals. If the codes and/or standards to which the product is certified have changed in the last year, ICC-SRCC staff will review the product to ensure that it complies with any new or revised requirements before issuing the recertification. ICC-SRCC staff will remind you of an upcomingrenewal months prior to the expiration to help you ensure that there is no gap in your coverage.

  • SHC Products

    Like the OG-100 and OG-300 programs, ICC-SRCC has a specific mark used to indicate that a product has received a ICC-SRCC listing shown below (specific usage is established in the ICC-SRCC Listing Program Agreement). The code listing mark does not replace the OG-100 or OG-300 marking requirements. It is applied in addition to them.For more information on ICC-SRCC requirements for marking and labelling, see the ICC-SRCC Trademark, Certification Mark and Certificate Use Policy posted in the Policies Section of the ICC-SRCC website.

    ICC-SRCC will also issue a separate listing award document (certificate) that will be available for viewing on the ICC-SRCC website in much the same way as OG-100 and OG-300 certifications. It will list the specific codes and standards to which listings are provided and the time period when the listing is valid. See the Listing Directory for current listing certificates.

  • For systems, such as solar thermal systems, listings can significantly ease the process of approval and acceptance by code officials in the field. This is especially true for unique and novel systems or where components and parts are not readily visible in an assembly.

  • No, obtaining a listing from ICC-SRCC or any other listing agency is voluntary. However a listing provides a manufacturer a proven way of demonstrating compliance with key codes and standards and can facilitate acceptance and approval in the field. It also provides a way of setting yourself apart from your competition.

    Model plumbing codes do require third-party certification to the standards referenced by a code, but not to a code itself. For example, the 2015 International Plumbing Code (IPC) reads:

    • 303.4 Third-party certification. All plumbing products and materials shall be listed by a third-party certification agency as complying with the referenced standards. Products and materials shall be identifiedin accordance with Section 303.1.

  • Possibly. Contact us to discuss the specific details of your product or system.

  • Yes. Each file may contain both collectors and systems. The only limitation is that all products or systems in a given listing file must be listed to the same selection of codes and/or standards. If you want to have some models listed to certain codes and standards and other models listed to different codes and standards, you will need to submit a separate application to get a file for each set.

  • A file is a single listing containing a number of models of collectors, systems or other solar thermal components, all evaluated to the same codes and/or standards. If you want to get some models listed to certain codes and standards and other products listed to different codes and standards, you will need to submit a separate application to get a file for each set.

  • As many as you want. There is no limit to the number of models included in a listing file, and each file may contain both systems and components. The only limitation is that all models in a given listing file must be listed to the same selection of codes. If you want to have some models listed to certain codes and standards and other models listed to different codes and standards, you will need to submit a separate application to get a file for each set. Files containing more than 100 models may be subject to additional fees. Contact ICC-SRCC for more details.

  • ICC-SRCC is accredited by the International Accreditation Service (IAS) to provide certifications and listings for Solar Heating and Cooling products, including solar thermal collectors and solar thermal water heating systems. ICC-SRCC is also accredited to offer EPA ENERGY STAR certification for solar thermal systems to the ENERGY STAR® Program for Residential Water Heaters.

    Examples include solar thermal collectors, solar thermal systems, heat exchangers and pump stations. Note that listings are only valid for use in solar heating or cooling applications, per ICC-SRCC’s accreditation.

  • In developing this program, ICC-SRCC sought to include every possible model code and standard addressing solar heating and cooling products. Our goal was to make ICC-SRCC a true one-stop-shop structured to meet all of a manufacturer’s listing and certification needs. Some codes are specific to certain types of products, applications, and certain regions of the country. There is no single plumbing or mechanical code in use in the U.S. and as a result, local requirements vary. If you are not sure which to select, ICC-SRCC staff will be happy to assist.

  • ICC-SRCC offers listings to all major model codes and standards that address solar heating and cooling systems. Currently, ICC-SRCC participants may apply for listings for one or more of the following:

    • International Plumbing Code® (IPC)*

    • International Mechanical Code® (IMC)*

    • International Building Code® (IBC)*

    • International Residential Code® (IRC)*

    • International Energy Conservation Code® (IECC)*

  • ICC-SRCC’s certification programs, OG-100 and OG-300 are for solar thermal collectors and solar thermal systems, respectively. They evaluate and rate models to ICC-SRCC’s Operating Guideline Documents, which in turn reference ICC-SRCC’s Consensus Standards and rating procedures. So for example, collectors are certified to ICC-SRCC’s OG-100 document. Under that program, collectors are tested in a lab to the ISO 9806 standard, and the results are evaluated using ICC-SRCC Standard 100 and rated using ICC-SRCC’s RM-1 document, as spelled out in the OG-100 document. ICC-SRCC now also offers optional listings to specific extra standards under both OG-100 and OG-300 at the request of the participant (see the following question for more information)

    Listings to codes and standards involves assessing a product or system’s compliance with the relevant requirements of one or more specific model plumbing, mechanical, building codes and/or standards adopted by jurisdictions around the U.S. Unlike the ICC-SRCC certification programs, ICC-SRCC’s listings do not result in a performance rating.

  • Yes. ICC-SRCC has been approved by the City of Los Angeles Department of Building and Safety’s Mechanical Testing Laboratory as a Recognized Listing agency for plumbing products to the ICC-SRCC 100 and ICC-SRCC 300 standards. You can view the List of Approved Listing and Testing Agencies at http://ladbs.org/LADBSWeb/LADBS_Forms/TestLab/MTL_Testing_Agencies.pdf

  • ICC-SRCC is recognized by code officials throughout North America. As a part of ICC-ES, ICC-SRCC is backed by the largest association of building officials in the country. Codeofficials know and trust the ICC-ES name. We’re even approved as a listing agency by the City of Los Angeles.

    ICC-SRCC’s solar thermal certification programs are accredited by the A2LA (Certificate #3299.03) to ISO/IEC Standard 17065 (2012), Conformity assessment - Requirements for bodies certifying products, processes and services, for the certification of solar heating and cooling equipment.

    If you ever have an issue with the acceptance of the ICC-SRCC Listing Mark in the field, ICC-SRCC staff will work with you and the code official to answer any questions regarding the listing.

    • AFFORDABILITY. ICC-SRCC charges a low flat fee for listing files. We even allow you to place collectors and systems in one file. And there is no fee for additional codes and standards.

    • EFFICIENCY. ICC-SRCC uses the information you’ve already provided for your OG-100 or OG-300 certification to conduct your listing. So there’s no need to resubmit the same information to another company. If we need additional information to process your listing, we’ll let you know.

    • FACTORY INSPECTIONS. In-person factory inspections are only required every two years. Plus, the inspections satisfy surveillance requirements for the OG-100 and 300 certification programs. You save money and avoid redundant inspections. We even offer a Global Solar Certification Network inspection option to reduce redundant inspections for other international certification programs.

    • LISTINGS BY THE EXPERTS. Listings are done by ICC-SRCC staff who are solar thermal experts, not by generalists who don’t know the intricacies of your products like we do.

    • SPEED. If you apply for listings when you apply for certification, we will get started on both right away. And since the code listings are coordinated with our certification programs, we can avoid redundancies and complete our reviews quickly.

    • VISIBILITY. Listings are linked to the ICC’s publicACCESS and premiumACCESS code portals, making it easy for users to find the SRCC Listings that apply to various sections of the I-Codes. That places your listings in front of millions of users of these online code portals. It’s a service that only ICC-SRCC and ICC-ES can offer.

    • TRUSTED. Listings are done by ICC-SRCC staffers who are solar thermal experts. We know your products and we know codes and standards. Code officials throughout North America trust and recognize our lists to provide them with the information they need to approve solar thermal products and systems. We’re even approved as a listing agency by the City of Los Angeles.
