2 The world s best energy is free and fiery One thing is certain: the sun rises each and every day. Besides giving light and life, the sun emits enormous amounts of energy and heat. A solar heating system from ARCON Solar can help ensure the lowest possible heating costs. Besides which, the sun is the cleanest of all energy sources it emits no CO 2 and solar heating systems make no noise and do not spoil the look of the countryside. In contrast to most other energy sources, solar heating systems ensure fixed low energy costs for many years to come. That is why there has been considerable growth in the number of new, large-scale solar heating installations, especially in connection with district heating plants. Many additional installations are in the pipeline and many of the plants that already have solar heating wish to expand their capacity. Similar developments are expected within industrial process heat. A large-scale solar heating system costs per m 2 about a fifth of the price of a smallscale system fitted to the roof of a house. Three large-scale solar collectors can provide as much energy annually as that required to provide an average singlefamily house with district heating. It is, in other words, not so much a question of whether or not to invest in solar heating but more of identifying the best solar heating solution. 2

In some cases by as much as 20%. Independence Stabilise the price of your heating While the price of fuels will rise in future, the sun provides energy at a fixed price: zero. As a result, the greater the proportion of a district heating plant's energy requirements which can be met by the sun, the better it will be for the plant's customers. Environment Reduce global warming Contribute to a sustainable future. The sun is our most powerful source of sustainable energy. A typical solar heating installation will reduce a district heating plant's CO 2 emission by about 1 ton for each household it supplies. 3

4 the world s leading supplier of largescale solar heating plants No-one knows more about large-scale solar heating plants than Arcon Solar. More than half the large-scale solar heating plants in Europe have been installed by ARCON Solar. The oldest plant can celebrate its twenty-fifth anniversary in 2013, provi ding unique historical documentation of operating results and efficiency. Flexible approach Solar heating systems from ARCON Solar can be installed in conjunction with any type of heating plant. Solutions can be chosen which provide as much as 50% of the energy produced. And if a smaller system is initially installed, it can always be extended later. Experience, competence and know-how ARCON Solar has worked with solar heating for more than 35 years and has installed more square metres of large-scale solar heating plants that any other company. Besides unique knowledge of the solar collectors themselves, ARCON Solar has extensive experience in all aspects of solar heating plant installation and can therefore help with system design, dimensioning and optimisation. Best product Specially designed to meet the characteristics and requirements of largescale solar heating plants, the HT solar collector has higher output than any other collector on the market. 4

5 The 10 largest solar heating installations in Europe ARCON Solar is behind most of the large-scale solar heating plants already established. 15 of the 25 largest plants were installed by ARCON Solar. In 2011 alone, ARCON Solar installed 48,000 m 2 of new solar collectors.

8 Why not use the world s most efficient solar collector? ARCON Solar s solar collectors are designed and developed for optimum performance in large-scale installations. Combining 40 years experience with the very latest technology, we offer high-performance solar collectors capable of operating perfectly at high temperatures for many years. ARCON Solar s solar collectors are the ideal choice for installations at district heating plants, where it is often necessary to increase production temperature, for energy storage purposes for example. 8

9 Efficiency ARCON Solar s solar collectors are among the most efficient in the world. Their high output is due among other things to the foil used, combined with the anti-reflection treated glass and laser-welded absorber.

10 Performance guarantee on the world s best solar collector Common for all our solar collectors is that they do the job better than any other solar collector. That s why we are not afraid to provide a performance guarantee. Although we have listed some of the most important advantages below, we are always delighted to discuss our products in greater detail. Exceptional durability ARCON Solar constantly seeks to find new ways of increasing the durability of its solar collectors. Weather-resistant aluminium frame and brazed joints ensure long service life. Our first large-scale solar heating plant, installed in Denmark (Saltum) in 1988, is still in operation. Optimised design Our solar collectors are designed to provide high temperatures. Besides the insulating foil, a high-performance, laser-welded absorber is used. This has an aluminium surface covered in a special selective coating, which ensures that almost all the sun's rays are captured and converted to heat. Manufactured by arcon solar By using tried-and-tested materials from European suppliers and manufacturing the solar collectors in our own production facillities, we ensure high quality, low transport costs and least possible CO 2 impact. Section of HT-SA solar collector Anti-reflection treated glass Foil tensioning Aluminium frame FEP foil Side insulation Rear insulation Absorber Foil between absorber and glass Foil positioned 20 mm from the glass creates an insulating effect, which reduces heat loss. In addition to this, the solar collector is insulated with an extra thick layer of mineral wool. The combined effect increases efficiency by up to 20%. 10

11 Low installation costs Thanks to low pressure drop, up to 22 solar collectors can be connected in series simply by attaching a flexible, stainless steel pipe. Piping is thus kept to a minimum, ensuring simple, cost-effective installation. Flexible product range Our solar collectors can be combined at will, i.e. different collectors can be installed in the same row. While solar collectors without foil are good at low temperatures, the insulating foil increases output at high temperatures. A combination of the two types provides optimum efficiency along the entire row of collectors. Performance guarantee The high quality and durability of our solar collectors, together with our many years' experience, mean we can offer a performance guarantee on our installations.

Commonly known as 28/10. To ensure optimum pressure throughout the field, collectors are also available in 35/10 and 28/8 variants. Our solar collectors are thus available in six different variants, which can be combined at will. 11

12 Our SOLAR COLLECTORS provide unlimited efficiency for large-scale heating solutions Since 1974, we have installed more than 300,000 m 2 of solar collectors in Denmark and other countries. We have installed systems in a great variety of locations, including heat stations, decentralised district heating plants, housing complexes, sports centres and swimming pools, holiday centres and camping sites, hotels and conference centres, care centres, schools, offices and businesses. 12

13 District heating plants A large-scale solar heating installation is the perfect supplement to a district heating plant, regardless of the fuel type used. A fixed low heating price can thus be assured for many years to come. Care centres, holiday centres and housing complexes ARCON Solar has good experience with systems installed in buildings where large quantities of hot water are required. In such cases, any surplus heat produced can be used to heat either rooms or swimming pools. Industrial process heat As industry uses energy both for heating purposes and for industrial processes, it can utilise the high temperatures obtainable in a solar heating system. 13

14 District heating A large-scale solar heating installation is the perfect supplement to a district heating plant, regardless of the fuel type used. Lower heating price Stable heating price Full flexibility A solar heating plant can give good savings. We have seen examples where average households can save up to DKK 3,500 in the first year. And this saving will rise in step with increasing cost of other energy types. A solar heating plant supplies a known amount of free energy each year, thus helping to stabilise heating costs. The price of all other fuels is expected to rise over time. Our solar heating systems can be installed in conjunction with any type of heating plant. Solutions can be chosen in which solar heating provides up to 50% of the energy produced. And if a smaller system is initially installed, it can always be extended later.
