1 INTRODUCTION

On May, 20, 2015, two senior technicians of the company, GEONICA, traveled to Dar es Salaam city to install the

Automatic Weather Station supplied to the Solar Consortium led by CENER, inside the ESMAP Project with ID:

P145287 and Selection # 1139235.

The objective was to install an Automatic Weather Station in the installations of the University of Dar es Salaam

(UDSM) as a part of the Phase 2 of the project. This is the first installation that the consortium is doing in Tanzania.

2 SITE DESCRIPTION

The emplacement identified is sited on the rooftop space above the main of the physics department building. The

campus is sited in Ubungo district of the Dar es Salaam City.. Fig 1 contains the aerial view of the campus and the red

circle signs the exact point of the emplacement. The site is currently specifically provisioned for meteorological

monitoring equipment.

Fig 1 Aerial view.

Fig 2 Details of the rooftop space to do the installation of the AWS type TIER 1.




December 2015

The exact coordinates of the Automatic Weather station Type TIER1 are the following:

Latitude 06º 46’ 51,9” S

Longitude 39º 12’ 14,0” E

Altitude above the sea level 122m

In the horizon analysis made in the site visits, it is determined that none critical obstacles are presented. Directly to the

east and west, in the middle distance, there are isolated trees whose crowns reach to an angle of 5˚ above the horizon

in both cases. The panoramic picture from the emplacement can be seen in Fig 3

Fig 3 Site Panorama

The other conditions that affect the suitability of the emplacement are all of them favourable

Dust: No nearby sources of dust; the campus is vegetated and surrounds the building for kilometres on all sides.

Access for O&M: The roof is easily accessed by spiral staircase, and is wide, flat and fitted with safety rails.

Heat Interference: None likely; the rooftop is isolated from its surroundings by plenty of open space.

Security: The University compound is guarded. The roof is accessible from the main building, and the access door

can be locked.

Future Interferences: There are no plans for new building works in the immediate vicinity of the emplacement,

Communications: There is 3G network coverage noted for Vodacom, Airtel, Zantel, Tigo.

3 AUTOMATIC WEATHER STATION CONFIGURATION

3.1 AWS SETUP

According to World Bank’s requirements for the Energy Sector Management Assistance Program (from now on

ESMAP) the Automatic Weather Station (from now on AWS) type TIER1 has to provide the highest accuracy

measurements, and use thermopile radiometers to measure all three components (GHI, DNI, and DIF). The sensors

chosen for the GHI and DIF measurements must meet ISO 9060:1990 Secondary Standards. The sensors chosen for

the DNI measurements must meet at least ISO9060:1990 First Class.

4 SUMMARY OF THE INSTALLATION OF AWS

May 20th

, 2015.

After the first visit to the location selected, it is confirmed that the foundations are not ready, so we had to talk with the

head of maintenance of University. We agreed with him, to prepare concrete foundation on the rooftop where it will be

fixed the anchors and the base plate of the tower and the solar tracker support with Epoxy resin

Foundations are made by the joint of 3 blocks concrete of 50*50*5 cm joint with cement. It is also specified that the

distance between both foundations, must be 4 meters.

Fig 7 Image of the concrete blocks used to make the foundations.

Fig 8 Detail of the foundations with the anchors and baseplate of the meteorological tower and solar tracker support.




December 2015

Fig 9 Detail of the distance between foundations

May 21st, 2015.

After solving small problems with the drills for the anchors of the foundations that it didn’t fit perfectly with the base of

the tower and the solar tracker support it is started with the mounting of the 3 meters tower and the solar tracker

support. The solution was to made new drills that match perfectly with the base plates.

Fig 10 Detail of the deviation of the drills on the foundations

Once the meteorological tower and the solar tracker support were fixed to the foundations, technicians started to install

all solar and meteorological sensors one by one.




December 2015

The solar radiation sensor for the measurement of global horizontal irradiance (GHI) was installed in the railing of the

rooftop. The decision to install here was to assure that nothing could generate shadows over the pyranometer that

could affect to the quality of the measurements.

Fig 11 View of installation of the pyranometers used for the measurement of GHI.

Once all sensors and equipment were mounted and installed, it is made a functional test of the complete AWS.

Communications through GPRS are tested from Madrid, SPAIN and locally by using a Computer of the University with

internet communications. All test run satisfactorily.

At the end of the installation, the technicians made a short training course to the staff of the university based, mainly,

on the maintenance of the weather station and the cleaning of the solar radiation sensors.

Communications software is also installed on a computer of the staff of the university.
