Package with SRCC rating information for concentrating solar thermal collectors

### Information

Package containing data for concentrating solar collectors. All models in the Concentraing package use EN12975 test data.

Extends from Modelica.Icons.MaterialPropertiesPackage (Icon for package containing property classes).

### Package Content

Name | Description
--- | ---
C_CogenraSunDeck | C - Cogenra Solar, Inc., SunDeck 1.0
C_VerificationModel | C - All inputs necessary for verification of EN12975 models

## Buildings.Fluid.SolarCollectors.Data.Concentrating.C_CogenraSunDeck

C - Cogenra Solar, Inc., SunDeck 1.0

### Information

Necessary data for calculating `dp_nominal`, `G_nominal` and `dT_nominal` is not provided in the EN12975 test data. All are left blank.

#### References

Ratings data taken from the Solar Rating and Certification Corporation website. SRCC# = 2011127A.

Extends from SolarCollectors.Data.GenericSolarCollector (Generic data record providing inputs for specific collector data records).

## Buildings.Fluid.SolarCollectors.Data.Concentrating.C_VerificationModel

C - All inputs necessary for verification of EN12975 models

### Information

No model on the Solar Rating and Certification Corporation website tested to EN12975 standards provides all of the necessary information for modeling. Specific limitations are `dp_nominal`, `G_nominal` and `dT_nominal`. This data record was created to allow verification of EN12975 base classes despite the limitations in available data.

Extends from SolarCollectors.Data.GenericSolarCollector (Generic data record providing inputs for specific collector data records).
