M&V Solar Water Heating Guideline - Eskom

Measurement and Verification Standard Guideline for Low Pressure Solar Water Heating Systems v1r1
5.1 Tests by South African Bureau of Standards (SABS)
The Required Tests in Compliance with the relevant South African Standards for
Supplying and Installing Solar Water Heater Systems in ESKOM’s SWH Program are given
in Table 1.

5.2 Essential Information from SABS Test Reports Used to Determine the
Performance of the Low Pressure Solar Water Heating Systems
The results from the tests according to SANS 6211-1: (or part 2) 2003 are essential for
evaluating of the thermal performance of the SWH systems.
This Guideline aims to develop a performance evaluation model which uses the main SWH
system parameters experimentally determined by the SABS tests as shown in Table 2.
