LIST OF COMPLETED PROJECTS
CRSES has a team of competent engineers and project managers who can assist clients with on- and off-grid renewable energy solutions. The dynamic group includes engineering expertise in the following disciplines: Mechanical, Mechatronic, Electrical, Process and Civil. The Centre is also well positioned to assemble expertise from the broader University community and private industry to participate in multidisciplinary projects. The past projects are listed under each year below:
| 2007 projects | 2008 projects | 2009 projects | 2010 projects | 2011 projects | 2012 projects |
2010
IN-HOUSE TRAINING SINGLE BUYERS OFFICE: ESKOM
Client: Single Buyer Office (SBO)
Scope: A course on renewable energy technologies and the grid-integration thereof was presented to the staff of the Single Buyer Office (SBO) which is currently housed in Eskom
SOLAR IRRADIATION ANALYSIS BASED ON SATELLITE DERIVED DATA FOR CSP PLANTS: UPINGTON
Client: Lereko Metier, SolAfrica
Scope: To compare the satellite derived solar DNI data of two sites in the Northern Cape. Monthly data over a period of 6 years were used from the HelioClim3 data base, as well as data from various other satellite derived data bases.
In addition measured data at Upington (obtained from SAWS) was compared to data from various satellite derived data bases.
Main Conclusions: The client installed a solar measurement station to further pursue one site.
INNOVUS DESIGN AND INSTALLATION OF PHOTOVOLTAIC SYSTEM
Client: Innovus
Scope: Design and install a 1 kW PV system.
Main Conclusions: The 1 kW is insufficient for the offices to be off-grid, as well as no storage being available. The PV system is however offsetting their electricity bill along with other energy saving practises such as timers and sustainable behaviour.
Continuation: Follow up on design to make offices completely off-grid.
Budget: Donation
AGI ALUMINIUM SOLAR WATER PANEL OPTIMISATION
Client: AGI Industries
Scope: Review and optimise an all aluminium solar water heater panel.
Main Conclusions: The initial solar water heater panel design was fundamentally correct, though there were some improvements to be made. Three aspects were analyse; 1) the fin thickness, 2) spacing between riser tubes and 3) diameter of riser tubes and the effect of small fins on the inside. The optimised design was a balance between manufacturing limitations and costing.
Continuation: The panel is currently being manufactured and the Centre may be called upon to perform performance testing.
STELLENBOSCH UNIVERSITY LOW FLOW SHOWER HEADS
Client: Stellenbosch University
Scope: Review three types of low flow shower heads.
Main Conclusions: The flow rate of water is not the only consideration that needs to be brought into account when installing low flow shower heads in public institutions. Of the three tested, the ones with the best and worst flow rates were discarded after a survey was conducted to determine the best shower head. The shower head was chosen based on the opinions and not engineering parameters.
Continuation: none
Budget: Free
SOLAR IRRADIATION ANALYSIS BASED ON SATELLITE DERIVED DATA FOR CSP PLANTS: EXXARO
Client: Exxaro
Scope: To compare the satellite derived solar DNI data of various sites in the Southern African region.
To produce DNI maps of Southern Africa for the purpose of identifying viable location to construct CSP plants.
Main Conclusions: Ongoing
SATELLITE DERIVED DATA FOR PV PLANTS
Client: Solar Capital
Scope: To compare the satellite derived solar LTI and GHI data of three sites specified by the client with local and international reference sites.
Main Conclusions: Ongoing
SATELLITE DERIVED DATA FOR PV PLANTS
Client: Nilafon t/a Ecozone
Scope: To compare the satellite derived solar LTI and GHI data of three sites specified by the client with local and international reference sites.
Main Conclusions: Ongoing
SOLAR INSULATION ANALYSIS BASED ON SATELLITE DERIVED DATA FOR CSP PLANTS: UPINGTON
Client: Lereko Metier, SolAfrica
Scope: To measure and assess the solar resource at a site specified by the client. A complete service is provided including the acquisition, installation and commissioning of the measuring equipment; downloading the data and verifying the integrity thereof; comparing the measured data with satellite derived data; liaising with an international service provider (DLR) to verify the results.
Main Conclusions: Ongoing
