Analysis of a Closed Loop Solar Energy System Using the -f Chart Method: Effect of Different Brazilian Locations (2013)

Submitted by Raquel Ponte Costa on January 6, 2015

This study, conducted by Alexandre M.S. Costa of the State University of Maringá and published by the State University of Ponta Grossa in Brazil, analyzes the annual energy performance of a closed-loop hot water solar thermal system under various weather conditions in 6 Brazilian cities (Curitiba, São Paulo, Rio de Janeiro, Recife, Salvador and Brasília) using the -f chart method. This method is based on 2 different approaches. It calculates the fraction (f) of monthly heat load that comes from solar energy.

Worldwide: Largest Flat Plate Collector Manufacturers in 2013

Submitted by Baerbel Epp on November 5, 2014
The number one in the ranking of the worldwide largest flat plate collector manufacturers based on collector area produced in 2013 is still Austrian OEM collector manufacturer Greenonetec, followed by three non-European manufacturers from BRICS countries: Soletrol from Brazil, as well as two companies from China, Prosunpro and Five Star. Germany’s largest flat plate collector manufacturer, Bosch Thermotechnik, only came in fifth place, down from being second in the previous ranking in 2012. German agency solrico created the ranking after carrying out a worldwide survey among companies serving the solar thermal sector in September and October 2014. Who has ranked how well this year shows a lot about the international trends of the global solar thermal industry.

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.

Brazil: Solar Thermal Market Diversifies in 2013

Submitted by Baerbel Epp on July 25, 2014
Brazil Market Statistics 1In 2013, the Brazilian solar thermal market grew significantly in both the unglazed segment of swimming pool absorbers and the glazed collector segment of solar hot water systems. According to the annual market statistics gathered in February 2014 by DASOL, the Solar Heating Department of the Brazilian Association of Refrigeration, Air Conditioning, Ventilation and Heating, ABRAVA, the glazed collector market continued its steep increase with another 20 % of growth last year. Regarding the unglazed market segment, the anonymous survey of the Brazilian market reveals that 2013 was a strong year, showing a growth rate of 18 % after two stagnating years (see the chart on the left). The total newly installed solar collector area was 1.38 million m2 – 20 % more than in 2012 (see 2012 market statistics). The share of glazed collectors was again at around 55 %. 

REN 21: Solar Thermal Contributes Significantly to Hot Water Production

Submitted by Baerbel Epp on June 30, 2014
top ten 2012According to REN21’s Renewables 2014 Global Status Report, which was published at the UN-hosted Sustainable Energy for All Forum in New York at the beginning of June, solar thermal technologies contribute significantly to hot water production in many countries and increasingly to space heating and cooling, as well as industrial processes. REN21 is a global multi-stakeholder network for renewable energy policy, connecting key actors from governments, international organisations, industry associations, science and academia, as well as civil society. First released in 2005, the report provides a comprehensive and timely overview of renewable energy markets, industries, investments and policy developments worldwide. The renewable energy data is provided by an international network of more than 500 contributors, researchers and authors. According to report data, the world added 55.4 GWth (more than 79 million m2) of solar heat capacity in 2012, increasing the cumulative installed capacity of all collector types in operation by over 14 % for a year-end total of 283.4 GWth. The chart above shows the shares in global capacity in operation across 2012’s top ten countries.

Guatemala: Growth without Subsidies

Submitted by Baerbel Epp on June 26, 2014
EnersolDespite the total lack of public incentives, the Guatemalan solar thermal market is growing at a steady rate. High electricity prices combined with a welcoming climate and market environment are turning solar thermal into an increasingly attractive technology. One of the country’s main solar thermal installers, Enersol, has been around for almost 30 years and installs both unglazed collector fields for swimming pools (left) and hot water systems for hotels and residential users (right).
