1 INTRODUCTION
This is a draft measurement and verification Solar Water Heating guideline that is developed
and needs to be approved by all the M&V teams before the finalisation of the guideline.
2 OVERVIEW OF SOLAR WATER HEATING PROJECTS
2.1 Introduction
The South African government has set a target for renewable
energy to contribute 10 000 GWh of final energy consumption
by the year 2013. According to the Department of Minerals
and Energy, an estimated 23% of the target could be
contributed by Solar Water Heating.
Although the initial focus of the Solar Water Heating
programme will be on a five year period (2007 - 2012), it
forms part of Eskom’s Demand Side Management (DSM)
programme, planned until 2025.
This draft Guideline describes how measurement and verification (M&V) is performed on
Solar Water Heating programme, as well as the basic M&V deliverables associated with it. Adetailed description is provided on the data that need to be gathered in order to develop the
project Baseline as well as the procedures that calculate the impact of the Solar Water
Heating programme.

2.2 Parameters in Solar Water Heating
In the world of Solar Water Heating, there are four primary aspects that play vital roles in the
performance of a Solar Water Heating System. Some of these parameters do not vary as
time goes by where others may vary significantly. To incorporate such changes in a SolarWater Heating model, a clear understanding of the four parameters are needed. A brief
discussion of the four parameters follows:
2.2.1 Solar Water Heating System
Many different types of Solar Water Heating Systems, each with their own performance
characteristics, will be distributed all across South Africa. To ensure that the National DSM
Solar Water Heating initiative is implemented with optimum effect, all systems need to
undergo and pass specific SABS tests.
The test results from SANS 6211-1:2003[1]
, which is set out by the SABS, characterises a
Solar Water Heating System in terms of its Energy Output (Q). The test method correlates
the Energy Output (Q), to the Solar Energy (H) incident on the system and the difference
between the daily average ambient temperature (Ta) and the incoming cold water
temperature (Tc). The following equation describes the correlation between the above
mentioned variables:
Q = Alpha1 x H + Alpha2 x (Ta - Tc) + Alpha3
Where,
Q, is the heat output in Mega Joules;
Alpha1, is the coefficient in the equation for heat output of the system in square
meters;
H, is the radiation received by the surface over a specified time interval in
Mega Joules/square meter;
Alpha 2, is the coefficient in equation for heat output of the system in
Mega Joules/Kelvin;
Ta, is the daily average ambient temperature in Degrees Celcius/Kelvin;
Tc, is the incoming cold water temperature in Degrees Celcius/Kelvin;
Alpha 3, is the coefficient in equation for heat output of the system in Mega Joules;

http://slidepdf.com/reader/full/mv-solar-water-heat-guide 7/31
Measurement & Verification Guideline: Solar Water Heating
The three Alpha coefficients are unique to a specific Solar Water Heating System and are
determined through regression when the energy obtained from the Solar Water Heating
System is compared to the radiation received from the sun. When the Alpha values are used
in conjunction with the equation mentioned above, the energy obtained from a Solar Water
Heating System can be determined according to varying environment conditions.
2.2.2 Solar Water Heating System Installation
2.2.1The radiation (H) mentioned in section above is dependant on the installation of a Solar
Water Heating System and influences the Heat Output (Q) of such a system.
The way in which a solar collector (solar panel) is tilted, determines the amount of radiation
that is incident on it and that can be absorbed by it. There are two degrees of freedom for the
installation:
Slope of the collector (measured from the horizontal angle)
Orientation of the collector
Figure 1 shows the slope of a solar collector and the slope-angle which is measured from the
horizontal.
Figure 1: The Slope and Slope-angle of a solar collector
Figure 2 shows the orientation of a solar collector which is measured from the True North
position. When converting Magnetic headings into True Headings one should subtract the
variation from the Magnetic Heading if the variation is west and add the Variation to the
Magnetic Heading, if the Variation is east.
A description of the variation, also referred to as declination, is attached in Appendix C. More
information regarding variation can also be viewed on www.thecompasstore.com.

Figure 2: The Orientation of the solar collector
The location of a Solar Water Heating System is also very important, as each location has its
own radiation level. Figure 3 shows how the Annual Solar Radiation varies at different location
in South Africa.

Measurement & Verification Guideline: Solar Water Heating
2.2.3 Solar Water Heating Hot Water Usage Profile
A Hot Water Usage Profile not only indicates the amount of hot
water used but also the time of use. This hot water usage profile
may vary according to the individual needs of persons living in ahousehold.
The hot water usage profile may also vary from household
to household. Many reasons for the variation exist but for
the purpose of this guideline the variance in hot water use
will only be linked to two factors:
Number of people living in a specific household
Occupancy during the day
The number of people living in a household will have a
direct influence on the hot water usage profile. Some
households accommodating only four people will use
approximately 135L of hot water per day where as a household with 5 or more people will
consume 175L of hot water per day.
The hot water time of use is equally important and should also be taken into consideration
when the hot water usage profiles are classified.
It should be noted that for the purpose of this guideline, a household appliance that draws
high quantities of hot water will be classified as an additional person.
At the time of this report ten different households, each with their own hot water usage profile,
have been identified and can be found in the SWH Hot Water Usage Profile Database. The
classification was based on Eskom’s indication of optimal SWH system size to be installed as
stated in the Eskom DSM-Solar Water Heating Operational Plan v5[6]
. The households are
classified as follow:
1. Household occupied during the day with:

2.2.4 Weather Information
As the driving force behind Solar Water Heating, the weather eventually decides if hot water
will be supplied to the household or not. When one thinks of the
weather factors like temperature, humidity and precipitation jumps
to mind. In the world of Solar Water Heating the following weather
parameters are required as well as a clear understanding of each:
Solar Radiation
Azimuth of the Sun
Altitude of the Sun
Ambient Temp
2.3 A National DSM Solar Water Heating Programme Procedure
Prior to understanding the M&V process of a National DSM Solar Water Heating Programme
the programme itself needs to be understood as it is different to a normal DSM project. The
process in short is as follow (please refer to Eskom’s Supplier Terms of Reference [6]
document for detailed process:)
1. Suppliers wanting to take part in the Solar Water Heating DSM Project have to complete
the necessary application forms and register each of their Solar Water Heating Systems
with Eskom. Solar Water Heating systems registered by the supplier must comply with a
set of non-negotiable factors to qualify for an incentive. One of the non-negotiable factors
is to comply with all relevant SABS standards relating to SWH Systems.
2. After the application has been approved the Supplier/Esco can now offer his/her product
to any costumer in any part of South Africa. Bear in mind that the Supplier/Esco does not
know who might walk through his door next to purchase a Solar Water Heating System.
This aspect of the programme makes pre-metering impossible.
3. Table 1 shows the installation possibilities that exist in the Solar Water Heating Project:

4. If a Solar Water Heating System is purchased the Supplier/Esco will keep book of the
purchase and claim back the incentive from the relevant parties.
5. An M&V team will be assigned to some of the Suppliers/Esco to do M&V on the Solar
Water Heating Systems which were installed by them.

3 MEASUREMENT AND VERIFICATION OF A SOLAR WATER
HEATING PROGRAMME
The M&V process is designed to provide an impartial quantification and assessment of project
impacts and savings that result from DSM activities. M&V also provide continuous feedback
to the various stakeholders (Eskom and Supplier/Esco) regarding the impacts achieved. M&V
consequently make a substantial contribution towards the sustainable implementation of DSM
and energy efficiency in South Africa[2]
.
The following sections describe the process on how to perform M&V on a Solar Water
Heating project. A number of standardised deliverables have been designed by the M&V
teams to achieve the objectives of this type of M&V project. Note that this methodology was
designed on the basis that a Supplier/Esco will be assigned to an M&V Team and will be
assessed on his/her SWH system installation country-wide.
The deliverables for the programme per assignment are:
• Scoping report;
• Baseline report; (Buy-in from the Esco/supplier should be obtained);
• Performance assessment report;
• Performance tracking reports.
The M&V plan is not omitted, since the prescribed methodology is given in this guideline.
3.1 The Scoping Study
The scoping study is the first stage in the M&V process after receiving the request to perform
M&V on a Solar Water Heating project. The purpose of the scoping study is to enable the
M&V team to gather all relevant and available information on the project.
Step 1: SWH System Characterisation
During the Supplier registration process, information regarding the SWH System
is attached to the registration forms. Included in the attachment is the Product
Information Sheet which contains the results of the SABS tests, as well as other
information that will aid in simulating the SWH System. It is the role of the M&V
team to acquire this information during the Scoping Study stage from either the
Supplier/Esco or Eskom. The M&V team can now characterise each system
according to its performance indicators and features. An example of the Product
Information sheet can be viewed in Appendix B of this report.
Page 8
7/21/2019 MV Solar Water Heat Guide
http://slidepdf.com/reader/full/mv-solar-water-heat-guide 13/31
Measurement & Verification Guideline: Solar Water Heating
Step 2: SWH System Number
A unique SWH System Number (E.g SS1) should be supplied to the
Supplier/Esco for each system that has undergone the SABS tests. The reason
for the SWH System Number is for easy identification of systems later in the M&V
process.
3.2 The Baseline
The Baseline for a Solar Water Heating project can only be developed after the Supplier/Esco
has sold the SWH System to the client. The Baseline will be a dynamic baseline which will
increase monthly as more SWH Systems are sold. For each SWH System installed an
additional hot water usage profile’s energy use will be added to the Baseline. It is for this
reason that buy-inn should be obtained from the Supplier/Esco on the ten hot water usage
profiles of which the Baseline will consist and not the for-ever-changing monthly Baseline
itself.
Step 1: Usage Profile Identification and Location
With the installation of every SWH System, the installer must complete the
Installer Sheet by asking the client several questions. General information
regarding the location of the SWH System is obtained in the first part of the form.
System installation information is obtained in the next part of the sheet after whichthe household type is identified.
The M&V team can now match the description of the household type in the
Installer Sheet to the typical hot water usage profiles in the SWH Hot Water
Usage Profile Database and select it.
The Installer Sheet is in Appendix B of this report.
Step 2: Baseline Calculation method
The Baseline calculation method is based on the assumption that the client would
have had a geyser installed prior to the Solar Water Heating initiative. Thus, the
Baseline for a certain SWH System will be the electrical energy use due to the hot
water usage profile prior to the installation of the SWH System.
The data required for the development of the Baseline is the following:
The hot water usage profile associated with each household
Number of households associated with a specific hot water usage profile
Page 9
7/21/2019 MV Solar Water Heat Guide
http://slidepdf.com/reader/full/mv-solar-water-heat-guide 14/31
Measurement & Verification Guideline: Solar Water Heating
Average Geyser size
Step 3: Baseline Simulation
The hot water usage profile can now be multiplied by the total number of each
household classification and summated to develop a collective hot water usage
profile for all the SWH Systems that were installed. The Baseline can be
simulated in the Residential Load Management (RLM) Model. The Baseline
should be updated and simulated on a periodic basis as more SWH Systems are
installed.
3.3 Impact Calculation
The Impact calculation of any DSM project is done by subtracting the actual
electrical demand profile from the baseline electrical demand profile. Solar Water
Heating Projects are no different.
A Solar Water Heating Application is used to simulate the SWH System and to
calculate the actual electrical profile. The inputs to the Solar Water Heating
Application together with weather data from an M&V Solar Water Heating
Weather Database, are then used to simulate the actual electrical profile. Typical
inputs to the Solar Water Heating Application are shown in Figure 4.

Figure 4: Inputs to the Solar Water Heating Application
If a SWH System contains an electrical backup element some where in the hot
water supply chain the Solar Water Heating Application will simulate the actual
electricity use profile. In the case where no electrical backup element is present
in the hot water supply chain the actual electricity use profile will be zero.
Once the Actual Demand Profiles are generated the impact of the Solar Water
Heating System can be calculated by subtracting the Actual Demand Profiles from
the Baseline Profiles.
Figure 5 and Figure 6 show the actual electrical profiles and impacts of a SWH
System with electrical backup and without electrical backup respectively as
calculated by the Solar Water Heating Application.

3.4 Performance Assessment
Due to the SWH System being purely seasonal dependant the performance assessment willbe done on a monthly basis over a period of a year. The purpose of the performance
assessment is to allow the ESCo to make adjustments to their DSM intervention to ensure
that it delivers what was contracted to Eskom.
The inputs needed for the Performance Assessment of a Solar Water Heating programme are
the following:
Begin and end date of performance assessment period;
Applicable energy tariff structure;
Baseline Profile for the month;
Actual electrical Profile for the month;
Conversion factors to determine the following emissions: CO2, H2O, NOx, SOx;
The output is a Performance Assessment report, containing the following:
Summary of the total monthly energy savings per billing period;
Summary of the monthly energy savings per type, per climatic region;
Monthly average impacts on energy, cost, CO2, H2O, NOx, SOx and particulate.
The reason for the monthly energy savings per type, per solar region is purely to identify SWH
Systems that perform or under perform in certain solar regions
The performance assessment reports will be sent to all project stakeholders.
3.5 Sustainability Checkups and Performance Tracking
3.5.1 Sustainability Checkups
Sustainability checkups are done by spot-checking the Solar Water Heating Systems after a
period of six and twelve months to determine the sustainability of the Solar Water Heating
project. A Fieldworker, accompanied by an M&V Fieldworker Form, gathers all relevant
information to determine the sustainability of the Solar Water heating System. The M&V
Fieldworker Form is in Appendix B of this report.
The purpose of the sustainability checkups are to determine if the Solar Water Heating
System is working satisfactory or has it been bypassed.

Measurement & Verification Guideline: Solar Water Heating
3.5.2 Performance Tracking
The Performance tracking reports provide a tracking of the savings that has been achieved
after the performance assessment stage. These reports are submitted every month to all the
DSM stakeholders. The purpose of this report is to provide verified savings to thestakeholders.
This report has the same basic structure and sections as the performance assessment report.
The only difference is the fact that the first part of the report provides the project impacts for
the month for which the report is compiled. The accumulated section provides the impacts
obtained over the total period to the date of the report for which the project delivered were
active.
In other words, each consecutive month will contain the previously installed Solar Water
Heating Systems impact as well as the newly installed Solar Water Heating Systems for that
specific month.

6 MAGNETIC DECLINATION
From Wikipedia, the free encyclopedia
Magnetic declination.
"Magnetic North" redirects here, for other uses see Magnetic North (disambiguation)
The magnetic declination (also known as grid magnetic angle in militarycircles) at any point on the Earth is the angle between the local magnetic field-- the direction the north end of a compass point -- and true north. Thedeclination is positive when the magnetic north is east of true north. The term
magnetic variation is equivalent, and is more often used in aeronautical andother forms of navigation.
