With the SOLCAL app for MsWindows the energy performance of a solar device is calculated, based on component test data, for use in the European Energy labeling regulation. The app is a follow-up of the successful Excel SOLCAL application offered by vAConsult that has been downloaded by more than 5000 users up to now.
The SOLCAL app is equipped with two implementations of the SOLCAL method:

- The commonly applied method described in the European publication (03.07.2014, C 207/22)
- The new implementation described in the FprEN 15316-4-3, annex F (*)

Pricing of the SOLCAL App:
- Budget edition: 100,- (excluding VAT)
- Professional edition: 150,- (excluding VAT)

The SOLCAL software is available in two configurations:

Just enter the components data, select one of the SOLCAL implementation and read the calculation results. This version is perfect for organizations that are only interested in the calculation results.

The same basic functionality, but now with professional added values, like saving data, composing new solar devices from previously defined component data, reports and the required ErP documentation. This version is a 'must have' for companies supplying solar devices.

(*) SOLCAL method explained
The SOLCAL method is one of two designated methods in the European energy label regulation (CDR 812/2013) to determine the energy performance of a solar device for water heating. The SOLCAL method, based on the CEN EN 15316-4-3 method B, uses component performance data from component tests to calculate the performance of a solar device.
Currently the SOLCAL implementation described in the European publication (03.07.2014, C 207/22) is commonly applied. Unfortunately, this implementation contains faults, causing too low performance results.

This year the CEN FprEN15316-4-3 has been accepted and will be published soon. Annex F of this standard gives a new and improved implementation of the SOLCAL method. Although this method of the FprEN15316-4-3 is not yet formally harmonized, this new implementation can be applied for better results, with reference to article 5 of the CDR812/2013:

The information to be provided pursuant to Articles 3 and 4 shall be obtained by reliable, accurate and reproducible measurement and calculation methods which take into account the recognized state-of-the-art measurement and calculation methods, as set out in Annex VII and Annex VIII.
