Tunisia: Ups and Downs of Prosol Subsidy Scheme

Submitted by Baerbel Epp on December 15, 2014

Tunisia’s incentive and low-interest loan scheme Prosol can already celebrate its tenth anniversary next year. Since 2005, the Tunisian Company of Electricity and Gas, STEG, has been managing the programme, which enables end consumers to repay a loan for a solar water heater over five years by having the instalment amount charged to their monthly STEG electricity bill. The programme was praised as an ideal showcase for the entire region, because market volume grew by more than a factor of ten in only five years. Before the start of the grant programme in 2005, Tunisia had only had an annual installation figure of 7,000 m2. In 2008, the subsidised collector area was already at 80,000 m2. But last year, market volume dropped to 53,000 m2 because of several factors listed below.

Namibia: Solar Water Heaters as Demand-Side Measure

Submitted by Baerbel Epp on December 3, 2014
NamibiaNamibia has an abundance of solar irradiation – but a lot of electric hot water boilers. Solar water heaters are seen as a strong demand-side measure to save about 30 % of the electricity consumption across the country. This was the key message by Helvi Ileka, Project Officer at the Namibia Energy Institute (NEI) at the Polytechnic of Namibia, during her presentation at the Solar Energy Technology in Development Cooperation conference in Germany at the beginning of November 2014. The government in the southern African country has been promoting solar water heaters since 2007, when the cabinet approved a directive that requires all public and parastatal buildings to cover their hot water needs by solar thermal. Namibia’s Vision 2030 goes far beyond that.

Canada: Aéronergie’s Acquisition of Enerconcept Leaves Company and Product Names Intact

Submitted by Baerbel Epp on December 3, 2014
Lubi WallAt the beginning of October, Canadian air collector manufacturer Enerconcept became part of Canadian engineering company Aéronergie. Aéronergie is a young company, founded three years ago with the aim of offering efficient heating solutions to manufacturers which “keep spending large amounts on energy in spite of unseen substantial savings,” according to a press release from 7 October. “With the acquisition of Enerconcept, Aéronergie extends its portfolio into solar in a big way,” the press release adds. Aéronergie and Enerconcept have been working together since 2012, the former as a complete solution provider and the latter as an installer. Both companies realised a number of projects together by offering comprehensive packages to industry owners and reducing their heating costs by 60 to 90 %. The photo shows one of these projects - a 230 m² Lubi wall with a cross-flow heat recovery unit at the industrial painting specialist Fuzion TK in the town of Drummondville in the Québec province.

USA: Saving Money with Solar Heat – A Brochure Highlights 27 Commercial Case Studies

Submitted by Baerbel Epp on December 2, 2014
Buggy Bath Car Wash“We use solar-heated water,” says a large advert sign in front of the Buggy Bath Car Wash in Bozemann, in the US state of Montana. The owner decided to install a solar water heater system not just to save money, but also to attract customers. The drainback system with eight collectors from Californian manufacturer Sunearth cost around USD 11,900 after incentives and saves around USD 1,400 annually. The payback period is estimated at 8.5 years. This solar car wash is one of 27 commercial solar heating and cooling case studies which were described in a new study released in October 2014 by the Solar Energy Industries Association (SEIA). The report is the first of its kind and focuses on the technical, as well as the economical aspects of the installations.
