South Africa: Incentive Programme Nears Government Approval

Submitted by Baerbel Epp on June 28, 2015
SESSAUntil recently, the solar water heater (SWH) rebate programme of state-owned power provider Eskom had been a key element in South Africa´s endeavour to cope with continually unstable power supply and become a more environmentally friendly society. Eskom granted refunds to customers replacing conventional geysers in households and commercial buildings with solar thermal ones. The result: 85,000 high-pressure solar water heaters funded by the rebate programme since 2008, according to estimates by the Sustainable Energy Society of Southern Africa (SESSA). The non-governmental organisation representing the local solar thermal industry wrote in its weekly newsletter, Energy Fix – Week 21, that 330,000 low-pressure systems were installed from 2010 until the end of 2012.

Local Employment through the Low-Pressure Solar Water Heater Roll-out in South Africa (2013)

Submitted by Raquel Ponte Costa on February 18, 2015

This study has been conducted by the Energy Research Center of the University of Cape Town and aims at demonstrating how developing low-pressure solar water heaters (LP SWH) can have an impact on reducing poverty and inequality and creating employment possibilities in South Africa.

South Africa: Building Regulation Not Applied as Intended

Submitted by Baerbel Epp on February 1, 2015
SOLTRAIN stakeholder meetingExtended South African National Standard SANS10400 XA, Energy Usage in Buildings, is the big hope of the country’s solar thermal system suppliers. Part XA 2, which was added to SANS 10400 in September 2011, reads: "A minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels.” The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority (for more details, see the attached architectural guide). After a transition period and a broad discussion among those affected by the new regulation, XA officially became law on 9 September 2014.

National Building Regulation in South Africa

Submitted by Baerbel Epp on February 1, 2015
Since September 2014 the extended South African National Standard SANS10400 XA is in force that stipulates that a minimum volume fraction of 50 % of the annual average heating requirement for hot water shall be provided by means other than electric resistance heating or fossil fuels. The regulation applies to all new buildings with hot water consumption, as well as refurbished ones if the refurbishment requires planning approval from a local authority.

Submitted by Baerbel Epp on January 20, 2015
The 3rd Southern African Solar Energy Conference (SASEC 2015) will be held from 11 to 13 May 2015 Conference Centre in the Skukuza Rest Camp, Kruger National Park, South Africa. The conference will focus on Photovoltaic and Solar Thermal technology, systems and applications and will provide the opportunity for solar energy researchers, engineers, technologists and individuals to share and discuss recent developments in their field.
 

The South African Solar Thermal Technology Road Map (2014)

Submitted by Francesco Gattiglio on December 5, 2014

This document illustrates the strategies of the South African Solar Thermal Technology Roadmap (SA STTRM), a project within the South African Solar Thermal Technology Platform (SA-STTP) which supports the use of solar energy sources for applications such as water heating, (solar) cooling, process heat and low temperature steam.

South Africa: Fresnel Collectors Keep It Cool in MTN’s Server Rooms

Submitted by Baerbel Epp on August 28, 2014
Industrial SolarSince June 2014, a Fresnel collector field with 242 kWth has been feeding into the district cooling system of the MTN Group at its headquarters in Johannesburg, South Africa. MTN, which has more than 200 million customers, as well as subsidiaries in 22 countries across Africa and the Middle East, is one of the leading mobile operators in South Africa – and it is aware of the impact of global warming. “We continuously explore ways in which we can lessen the impact of our operations on the environment. This initiative will not only reduce our carbon footprint but it will substantially reduce our electricity consumption, which will release additional capacity for the national grid,” MTN’s CEO, Zunaid Bulbulia, was quoted as saying in a press release from 17 July 2014. The concentrating solar thermal plant powers the double-effect absorption chiller whose cooling capacity of 330 kW keeps temperatures low in the data centre at MTN’s head office.
