Tunisia: Good Hotel and Hospital Investment Opportunities

Submitted by Baerbel Epp on June 8, 2016
Tunisia StudyA great deal of sunlight, large investment grants and subsidised energy prices: These are the factors determining the profitability of big solar thermal systems in Tunisia, according to the authors of the study Opportunities for solar thermal systems in the tertiary and industrial sectors in Tunisia, a publication by the German Agency for International Cooperation, GIZ, (see attached document in English, the French version is under consultation). Under certain circumstances, a solar thermal system can achieve a double-digit Internal Rate of Return (IRR), for example, if it is installed at LPG-dependent hotels or hospitals on the Tunisian island of Djerba. When solar replaces natural gas in commercial buildings in Tunisia’s capital, Tunis, the IRR is still significantly higher than the estimated 4.3 % inflation per year. However, there are difficulties with the economic feasibility of solar process heat applications because not even top reference cases have fulfilled investor expectations. The authors emphasise that the importance Tunisian businesses currently place on payback periods for investing may lead them to overlook valuable projects.

Armenia: Green Leasing Programme to Fund Solar Water Heaters at Hotels

Submitted by Baerbel Epp on May 16, 2016
Tufenkian Hotel 1Armenia, a small country in South Caucasus, is home to an innovative financing scheme for solar thermal systems and other energy efficiency measures. In 2014, Armenian ACBA Leasing launched the Green Leasing programme for small and medium enterprises from any industry. According to an article published on 24 March 2016 on Armenian news website news.am, Green Leasing had already helped fund several solar thermal systems for different customers, such as seven hotels, four catering businesses and more than 20 service companies. One of the most well-known customers was the Tufenkian Hotel in Yerevan, Armenia’s capital: The roof installation of 1,140 vacuum tubes was done in December last year (see photo).

Spain: EUR 2 Million in Subsidies for Solar Heat Providers

Submitted by Baerbel Epp on June 2, 2015
VillafrancaEighteen solar heat projects have profited from the national incentive scheme, Solcasa, in Spain since May 2010. The programme has been offering low-interest loans to Energy Service Companies (ESCOs), which install, operate and maintain solar thermal installations to sell their solar gains to customers, such as hotels or multi-family building owners. To date, the administrator of Solcasa, the Institute for Energy Diversification and Saving, IDAE, has granted loans of EUR 2.09 million to 18 projects totalling 2.32 MWth. The photo shows the roof installation owned and operated by Spanish company Sumersol at the nursing home in Villafranca de los Caballeros, a town in eastern Spain.

Monitoring and Modeling Hot Water Consumption in Hotels for Solar Thermal Water Heating System Optimization (2011)

Submitted by Raquel Ponte Costa on April 11, 2015

This thesis paper was written by Eric Joseph Urban at Appalachian State University. It concerns how to properly model hot water consumption in hotel lodgings in order to accurately optimize solar thermal installations.

Spain: Canary Islands Publish Guide on Hotel Solar Use

Submitted by Baerbel Epp on February 21, 2015
Reference Hotel Canary IslandThe regional government of the Canary Islands has published a guide on increasing the use of solar thermal in the local hotel sector. The government presented and distributed the study TRNSHOTEL, an analysis and proposals to optimise the solar thermal energy consumption in the Canary Islands hotel sector, during public seminars on 26 and 27 November 2014. The study can be a useful means of developing solar water heating technology in a region boasting a huge tourism sector but great untapped solar potential. The figure shows the 146-room hotel which was used as a reference throughout the study and was simulated in TRYNSYS by the Instituto Tecnológico de Canarias (ITC) to analyse building orientation and list the different solar energy yields and cooling loads (see the attached TRNSHOTEL PDF).

Jordan: “The solar bylaw is not going to have a strong impact on the market”

Submitted by Baerbel Epp on January 6, 2015
Millennium Solar EnergySince April 2013, Jordan has had a solar bylaw in place. The rules of the bylaw were stipulated in Article 10 of Law No. 73, which had already entered into force in 2012. Solar water heaters are a mandatory requirement for every new multi-family building with more than 150 m² of living space, for every new office building exceeding 100 m² of floor space, as well as each new public building with more than 250 m². There are, however, no additional regulations regarding quality standards or system sizes. Solarthermalworld.org spoke with Angelika Cerny, International Sales Coordinator at Jordan-based solar thermal turnkey-solution provider Millennium Energy Industries (MEI), about the effectiveness of the bylaw and the market development in Jordan. The photo shows an 80 m2 vacuum tube collector field which was set up in 2013 as a pergola for the office building of Jordan company EDGO Ventures in Amman.

Solar Thermal Energy in Cape Verde – State of Development (2014)

Submitted by Francesco Gattiglio on November 20, 2014

This document was presented at the ECOWAS Solar Thermal Energy Capacity Building and Demonstration Programme conference held on 13 and 14 June 2014 in Praia, Cape Verde. The presentation provides an overview of the usage of solar thermal energy in the touristic sector of Cape Verde.

Colombia: New Law Promises Tax Incentives

Submitted by Baerbel Epp on July 17, 2014
Hotel Plaza ColombiaA new law has just provided the framework to offer renewable tax incentives in Colombia. The law will now be followed by a decree, which is expected to be finalised within less than a year and will specify the objectives and support measures for different renewable energy technologies. Still, some companies are currently seeing the market grow even without any incentives in place, especially in the hotel and healthcare sector. The photo shows a field of 150 collectors on the roof of the Hotel Plaza in Bogotá. The system covers more than 40 % of the hotel’s hot water demand.

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).
