There are several factors that could cause the solar fraction for the Very Small Usage Pattern to be lower than the Low Usage Pattern. The DOE Hot Water Usage Patterns withdraw different amounts of water at different times of the day. The timing and amount of each hot water draw relative to the amount and […]

Who can obtain an OG-300 Puerto Rico Supplement?
Any current OG-300 certification holder may apply for a Puerto Rico Supplement to be added to their existing OG-300 certificate. Therefore only the holder of the OG-300 certificate (manufacturer, designer, etc) can apply for the supplement. Once completed, PR Supplements are added to the OG-300 certificate and are publicly available on the SRCC OG-300 Directory […]
What if I want to find out what the ratings in Puerto Rico would be without necessarily ordering the Supplement?
ICC-SRCC offers a modeling service to OG-300 certification holders to preview the ratings that would appear on a Puerto Rico Supplement. If the manufacturer then chooses to apply for the supplement after modeling, the modeling charge is credited to the application fee for the supplement. Contact ICC-SRCC for more information on modeling services.
Can a manufacturer get the Puerto Rico Supplement for a solar water heating system without first getting OG-300 certification?
No. Solar water heating systems must first have an active OG-300 certification before they are eligible for a Puerto Rico Supplement.
How long are OG-300 Puerto Rico Supplements valid?
Supplements to the OG-300 program are tied to the associated OG-300 certification. They are valid until the individual certification expired or until the manufacturer requests their withdrawal. When the OG-300 certification for the system is subject to renewal, the manufacturer can determine whether to also renew the supplement.
I received a hardcopy printout of an OG-300 Puerto Rico Supplement. How can I check to be sure that it is still valid?
ICC-SRCC posts all valid certifications and supplements on its web directory at www.solar-rating.org. You can also go directly to the OG-300 directory. Once there, look up the OG-300 certification number from the supplement. Once you find the certificate, click on the link to view the document. If the Puerto Rico Supplement is valid for that […]
If a manufacturer has an OG-300 Puerto Rico Supplement for their solar water heater, does that mean that they also have ENERGY STAR certification?
Not necessarily. ENERGY STAR certification is not required to obtain the OG-300 Puerto Rico Supplement. But if a manufacturer has ENERGY STAR certification for the system through ICC-SRCC, it will be noted on the supplement.
What are the DOE Hot Water Load Patterns used in the OG-300 Puerto Rico Supplement and ENERGY STAR certifications?
Hot water load patterns are used to indicate the size, timing and flowrate of hot water draws from the solar water heating system during a 24-hour time period. Different building types, occupancies, local practices and the time of year all impact the amount of hot water drawn from a domestic water heater. SRCC’s OG-300 program, […]
Why was the OG-300 Puerto Rico Supplement created?
Puerto Rico and other islands in the vicinity, like the US Virgin Islands, has unique conditions that differ from those in the continental US and Canada. They include: High solar radiation, relatively stable water mains temperature, and no freezing conditions. Significantly lower domestic water consumption per capita than the continental US, on average. High incidence […]
