Brazil: Impact of São Paulo Solar Obligation

Submitted by Baerbel Epp on November 13, 2015
Velp Mais BrazilSão Paulo’s around 30,000 new building permits per year and a municipality bylaw (Number 14449/2007) which has required construction companies to make solar water heating part of almost every newbuild since 2008 have created expectations for a flourishing solar thermal sector in this Brazilian city. Independent consultancies estimate that the local solar obligation has led to 110,000 m² of collector area installed at residential buildings.

Austria: Mysolar Offers to Replace Old Solar Thermal Collectors

Submitted by Baerbel Epp on November 9, 2015
DünhofenIn a country with a high market penetration of solar water heaters and a decline in new installations, companies have to look for new business opportunities elsewhere. For example, Austrian installation company Mysolar specialises in replacing old solar water heaters which have been losing efficiency because of aging collectors. At a fixed price, the company will replace old collectors by new ones.

Report on Solar Water Heating in the Tourism Industry (with a focus on the Caribbean Region)

Submitted by Francesco Gattiglio on October 29, 2015

Tourism is one of the main economic drivers in the Caribbean region. For many islands in the region, tourism is a major source of GDP and employment. Like all companies, tourism businesses seek to reduce operating costs and increase revenues. In the Caribbean region, tourism businesses face high and fluctuating energy prices because most islands rely almost entirely on imported liquid fossil fuels for energy generation.

In addition, Caribbean tourism businesses are facing increasing pressure to improve their environmental performance to meet the growing demand for greater sustainability in the travel and tourism industry. By implementing sustainability measures, the tourism industry can contribute to the region’s ambitious targets to reduce fossil fuel consumption and increase the share of renewable energy to total electricity generation. There are a wide range of sustainability strategies tourism businesses can pursue to minimize their environmental impact including adopting renewable energy technologies.

This report provides a starting point for tourism businesses that are interested in exploring the opportunity of Solar Water Heating (SWH), specifically, for small to medium sized hotels.

European Energy Labelling: Solar Manufacturers Have Doubts

Submitted by Baerbel Epp on October 27, 2015
Solrico energy labellingThere is great scepticism among Europe’s solar thermal collector manufacturers about whether or not the energy labelling will increase demand for solar thermal systems. In a survey carried out by German agency solrico, more than 50 % of the European solar thermal manufacturers disagreed with the statement “The energy labelling will foster your solar sales”. All in all, 158 solar collector and solar tank manufacturers in Europe answered the multiple-choice question (Do you agree with the following statement – The energy labelling will foster your solar sales?) by ticking one of five answers: strongly agree, agree, tend to agree, disagree and strongly disagree. The chart shows the results at national level. The figures in brackets display the number of valid answers from each country.

Solar Water Heating TechScope Greenhouse Gas (GHG) Reductions Calculator

Submitted by Francesco Gattiglio on October 16, 2015

The Solar Water Heating (SWH) TechScope Greenhouse Gas (GHG) Reductions Calculator is an Excel-based evaluation tool integrated as an additional module into the SWH TechScope Market Readiness Analysis Tool.

The SWH TechScope GHG Calculator provides complementary functions designed to help policymakers quantify GHG emissions reductions associated with increased development of SWH systems.

Solar Water Heating TechScope Market Readiness Assessment for Eight Caribbean Countries

Submitted by Francesco Gattiglio on October 16, 2015

This regional assessment report applies the SWH TechScope Market Readiness Assessments Methodology in eight Caribbean countries: Aruba, Bahamas, Barbados, Dominican Republic Grenada, Jamaica, St Lucia and Trinidad and Tobago. It is recommended that the SWH TechScope Market Readiness Assessment Report be read in parallel with this report.

The assessment report highlights that solar water heating (SWH) systems can be highly cost-effective across the Caribbean, taking advantage of the region’s abundant solar resource. The report remarks that persistent barriers to SWH adoption remain across many Caribbean countries, such as financial barriers, weak enabling policy environments, lack of public awareness, and small and fragmented SWH industries.

Technical Study Report on Measuring, Remote Monitoring and Remote Controlling for Solar Thermal Systems

Submitted by Francesco Gattiglio on October 15, 2015

Solar thermal suffers in the market, the media and the policy arena, because solar thermal energy is seldom accounted for, and the amount of solar thermal heat supplied is neither measured nor displayed in a transparent way. This also results into problems/malfunctions not being spotted quickly.

This technical study report on measuring, remote monitoring and remote controlling for solar thermal systems aims at contributing to making measuring, monitoring, and remote controlling more mainstream for smaller systems. It also intends to make use of some information from larger systems, where measuring, remote monitoring, and remote controlling are already common.

Technical Study Report on Solar Thermal Technology LCIA Methods and LCC Models

Submitted by Francesco Gattiglio on October 15, 2015

Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) Analysis are powerful tools to determine the impact of a product not only by its use but also its whole life cycle from cradle to grave. In order to establish reliability and comparability of Life Cycle Assessment, a comprehensive set of rules has been defined within international standards regarding LCA.

This technical study report on solar thermal technology Life Cycle Impact Assessment (LCIA) methods and Life Cycle Costing (LCC) models, aims at contributing to the demonstration of the advantages of solar thermal systems, taking the life cycle into account. This means assessing both environmental and economic benefits of the systems over their operation period. These methods allow to exemplify the diverse benefits of this technology during the life cycle of a system, in spite of its high upfront investments costs.

Austria: Hope for Market Decline Slowdown

Submitted by Baerbel Epp on October 9, 2015
Austria market developmentThe market report Innovative Energy Technologies in Austria. Market Development 2014 published by the Austrian Federal Ministry for Transport, Innovation and Technology (bmvit) shows that in 2014, the national solar thermal industry had to deal with declining sales for the fifth time in a row. The solar thermal market in Austria dropped by 15 % from 2013 to 2014, resulting in a total annual volume of 108.6 MWth (155,170 m²) last year. The pie chart shows the share of different segments in the collector area newly installed in 2014 [2013]. Multi-family buildings have significantly increased in importance. According to recent data by the industry association Austria Solar on the first two quarters of 2015, the decline seems to be slowing down, partly because of a new federal incentive programme.
