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 CO₂ – 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 m2_{about a fifth of the price of a} small-scale system fitted to the roof of a house. Three large-small-scale solar collectors can provide as much energy annually as that required to provide an average single-family 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.

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.

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.

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.

Specially designed to meet the characteristics and requirements of large-scale solar heating plants, the hT solar collector has higher output than any other collector on the market.

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 instal-led by ARCON Solar. The oldest plant can celebrate its twenty-fifth anniversary in 2013, provi ding unique historical documentation of operating results and efficiency.

We work closely with external consultants and district heating engineers, and are used to participating in all types of project, whether it be turnkey contracts or individual trade contracts.

ARCON Solar wishes to be the preferred solar collector supplier. To this end, we must provide the best product, high quality, professional documentation and project management, and expert technical sparring which ensures the best overall solution.

Our many years’ experience and countless references have given us a unique insight into the various stages involved in the planning and installation of a solar heating system. From consideration, decision taking and approval, through financing, authority approval, earthworks and installation, to testing and commissioning.

As the leading manufacturer of large-scale solar heating systems, ARCON Solar has comprehensive documentation which can be used for techni-cal analyses, techni-calculations and outline proposals.

ARCON Solar performs annual service checks, including physical inspec-tions, to ensure optimum system operation.

ARCON Solar can help define relevant objectives during this stage and can provide input for preliminary overall calculations. ARCON Solar has also considerable experience in selecting suitable installation sites.

ARCON Solar's solar collec tors can be installed at lowest possible cost as they are designed for large-scale installations and can be easily connected in series.

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.

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.

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.

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.

By using tried-and-tested materials from european suppliers and manufacturing the solar collectors in our own production facil-lities, we ensure high quality, low transport costs and least possible CO₂ impact.

eXCePTIONAL

DuRABILITY

MANuFACTuReD

BY ARCON SOLAR

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.

OPTIMISeD

DeSIgN

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%.

(11)

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.

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.

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.

Standard solar collectors are supplied with 28 mm connectors and 10 mm strips. 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.

Since 1974, we have installed more than 300,000 m2_{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.

A solar heating plant supplies a known amount of free energy each year, thus help-ing to stabilise heathelp-ing costs. The price of all other fuels is expected to rise over time.
