[en] The solar heating industry in Europe has reached maturity after more than two decades of technical development. High quality systems are now available with reliability and durability of the products being assured. The European solar market, now the world's largest, has been growing since the late 1980s, despite the fact that conventional energy sources are usually available and inexpensive. This is a new phenomenon and marks the beginning of changes in energy supply and consumption that will be experienced throughout the world in this new century. Almost 10 million square metres of solar thermal collectors now exist in Europe saving more than 1.5 million tonnes of CO₂ emissions and about 500,000 tonnes of oil. The solar heating industry has created some 10,000 jobs. (author)

[en] After a 10 year period of steady growth the French market of the thermal solar power dropped by 15% in 2009. Only 265.000 m² were installed instead of 313.000 m² in 2008. The main reason of this decrease is the economic crisis: the European market for thermal solar energy dropped by 10%. The second reason is the unfair competition of the photovoltaic power that benefits from very favourable electricity purchase prices, from higher subsidies and from a better image in the public's eye. Another competitor on the market is the new equipment called 'thermodynamic water heater' that involves a heat pump, this equipment is cheaper but only on a short term basis. (A.C.)

[en] The market potential for active solar thermal systems in the institutional, commercial and industrial sectors of the Canadian economy was investigated, the objective being to identify markets and to prepare action plans as the foundation for developing these markets by Natural Resources Canada and the industry. In the process of researching the market, barriers to market development in these sectors of the economy were also identified as well as actions to overcome these barriers. Nine potential applications were modelled to determine their energy, economic and environmental performance. Of these four attractive applications have been selected for more detailed treatment. Separate action plans have been developed for Natural Resources Canada, the Canadian Solar Industries Association and the active solar thermal industry. The close cooperation of all three partners is considered essential for a successful marketing effort. A marketing plan which gives due consideration to the product, planning, packaging, price and promotion, is also considered to be a vital ingredient, as is a meticulous follow-up on 'leads' created by exposure to the target market. Solarwall'TM' for preheating of ventilation air to new school buildings and solar domestic hot water heating for camp grounds have been identified as the most attractive candidates for marketing at this time. Highlights of marketing plans for these two options are included for purposes of illustrating the essential ingredients of marketing plans. 1 fig

[en] This report is based on a previous, related, one which was quantitative in character and relied on 500 telephone interviews with house-owners. The aim of this, following, report was to carry out a more deep-going, qualitative analysis focussed on persons who already own a solar heating system (purchased during 1992) or were/are considering having one installed. Aspects studied were the attitudes, behaviour and plans of these two groups with regard to solar heating systems. Some of the key questions asked concerned general attitudes to energy supply, advantages and disadvantages of using solar heating systems, related decision-making factors, installation problems, positive and negative expectations, evaluation of the information situation, suggestions related to information systems regarding themes etc., dissemination of information, sources of advice and information, economical considerations, satisfaction with the currently-owned system which would lead to the installation of another one in connection with the purchase of a new house. The results of this investigation directed at Danish house-owners are presented and discussed, and proposals for following activities within the marketing situation are given. It is concluded that the basic attitude in both groups strongly supports environmental protection, renewable energy sources and is influenced by considerations of prestige and independence. Constraint factors are confusion about environmental factors, insecurity in relation to the effect of established supplementary energy supply and suspicion with regard to the integrity of information received.

[en] In the nineties the 'project approach' has been developed in The Netherlands to overcome prevailing market barriers for the large scale market introduction of Solar Water heaters: poor economics, low acquaintance at consumer as well as at urban planning and architect level, a supposed low quality perception, complex subsidy handling and unfavorable building codes. Within this approach solar technology is offered to customers in different market segments in packages combining: the economy of scale, quality control, high quality solar energy systems and back-up heating systems, selective marketing and publicity focussed on the target group, financial, logistic, installation and after sales services. Since 1990 the annual solar collector sales in The Netherlands have increased from 5,000 m² to approx. 30,000 m² in 1999 due to a government program in which the project approach has been developed and repeatedly executed in new housing developments, renovation projects and in campaigns focussed at individual home-owners and more recently in the market segments were large scale solar systems can be applied. The project approach effectively triggers off long term market development. This takes place by the numerous follow-up projects and knowledge transfer to organizations participating in the various projects. Other important spin off for long term market development is the establishment of national solar installation/lease companies, the development of new financing and marketing methods and new kinds of promoters like banks and NGOs.

[en] In 2008, the European solar thermal market put on a strong spurt only to mark time in 2009 with about 4.2 million m² installed, which is 450000 m² less year-on-year. The main reasons of the decrease is the financial crisis and the low oil price, other reasons more specific to the country exist, for instance the property crisis has dragged the Spanish market down. In 2009, the solar thermal collector surface area in service in the European Union is of the magnitude of 32.6 million m², equivalent to a capacity of 22.8 GWTh. The solar thermal sector is one of the renewable sectors that creates the highest number of jobs and wealth, partly because the vast majority of the system components sold in Europe are produced in Europe and partly because the sale, installation fitting and maintenance are labour-intensive. In 2009, there were 50000 direct or indirect jobs in the European solar thermal sector. The main European actors in this sector are GREENoneTEC, Bosch-Thermotechnik, Viessmann, Vaillant and Solvis. No clear recovery is expected before 2011. (A.C.)

[en] This article focuses on applications of solar energy in Scandinavia. The development of retrofit solar techniques for houses, use of solar collectors, solar district heating, the Danish National Solar Test Laboratory for thermal and photovoltaic solar collectors, solar architecture, and solar equipment manufacturers are considered.

[en] The objective of the project is to develop and improve large procurements of solar heating systems in order to be able to place large orders with manufacturers and suppliers. The project work will be carried out as an international co-operation under IEA Task 24 with the title 'Solar Procurement'. By co-ordinating the effort between the 4-6 participating countries, the objective is to purchase at least 10,000 solar heating systems, of this amount 1,000-2,000 in Denmark. Such large orders make it possible for manufacturers and suppliers to deliver systems considerably cheaper, and it will be possible to develop systems for given specifications on output and efficiency. These co-ordinated large orders are expected to improve the price/efficiency conditions by up to 50%. The so called 'procurement process' (co-ordinated international procurement based on goal-oriented system development in co-operation between customers and suppliers/manufacturers) will in the project be followed up by information/marketing, education, financing schemes, service schemes, quality assurance and technical support. The project is divided into two main areas (IEA subtasks). 1: 'Procurement and Marketing' and 2: 'Creation of Tools'. Denmark has been requested to be the project manager of subtask 2, 'Creation of Tools'. (EHS)

[en] The paper describes the monitoring of manufactured solar heating systems for domestic hot water combined with space heating and systems for domestic hot water only. Results from the monitoring of 5 marketed combined systems for domestic hot water and space heating are presented. The systems situated at one family houses at different sites in Denmark have been monitored from January/February 1992. For the detailed monitoring of manufactured systems only for domestic hot water a test facility for simultaneous monitoring of 5 solar heating systems has been established at the Thermal Insulation Laboratory.

[en] The paper presents the opportunities for separate assemblage and dismounting of the structural layers of energy-accumulating panels, meant for construction of energy-active walls, which could find an application in the process of building of so called 'solar houses'. A situation has been considered, for a panel, whose structure layers after the expiration of their operational term could be dismounted separately and could be recycled for secondary use
