SUNSET – Your solar partner History At the end of the 1970s the idea was born to create an environmentally friendly, renewable and free source of energy with the help of the sun’s rays. SUNSET, with its head office in Adelsdorf near Erlangen in northern Bavaria, Germany, was founded in 1979. Since then, SUNSET has pursued this goal consistently and with success. Through its pioneering work SUNSET has helped solar energy be recognised as a genuine alternative to conventional forms of energy. SUNSET solar has developed into a leading privately-owned company within this new industry.

Development Meanwhile, solar technology has developed an independent source of energy. Thanks to rapid technological developments, solar energy is no longer only available for the privileged few: on the

contrary, anyone, who wants to act responsibly for their future and for posterity, is now in the position to make a prudent and affordable contribution by using solar energy.

Prospects SUNSET will continue to implement its founding ideas in the future, and will strive to improve solar technology as a professional product. The very high quality standards we set for our products are required for production in Germany. Our overseas production sites also comply to these stringent quality standards. Our European distributors and our branches around the world make SUNSET into a strong partner — now and in the future!

Why solar technology? Solar energy is environmentally friendly. Solar energy is benign. Solar energy is renewable. Solar energy is affordable for everyone. Hot water without solar energy

Hot water with solar energy

Saves 1,2 metric tons CO2

1,7 metric tons CO2

0,5 metric tons CO2 Yearly reduction of CO2 emissions through the se of a solar system by an average household with four occupants.

How does solar technology work? The principle is simple: the sun’s rays are absorbed by the collectors and heat the water of the solar energy system. The closed system extends from the roof to the cellar of the house and conducts the sun’s heat via a heat exchanger into a storage tank. The more solar collectors are installed, the more energy can be collected and used to heat hot water or to supplement a central heating system. It goes without saying that combined systems for heating swimming pools can be offered in any size.

The future will be powered by solar energy Where can solar technology be implement ed sensibly? The annual solar radiat ion in Europe is quite sufficient for the functioning of solar energy systems. Solar energy systems can save between 60 and 70 % of the energy otherwise needed to heat hot

water, year for year. In the summer months up to 100 % of energy requirements can be supplied by solar energy systems. Furthermore, solar systems can readily supplement central heating systems. Our high quality collectors can yield heat energy even with a cloudy sky.

How do solar hot water systems work?



c The sun’ s rays fall on the collector and are converted to heat. d The solar controller regulates the flow of heat to the storage tank. e The pump in the solar unit pumps the solar heat to the storage tank. Safety installations are also included in the solar unit to ensure that the whole system works reliably.

Hot water - for your swimming pool too! The solar absorber systems from SUNSET can serve to heat your private pool as well as a public open-air swimming pool and by ducing water with a temperature of between 24°C and 29°C, you can

extend the swimming season from early May to well into September, or beyond depending upon your climatic zone. A customised solution provides maximal efficiency

and effective system. The systems can be installed quickly and easily. Only high quality and recyclable materials are used. The absorber material has been given a ten year limited warranty. The cost of installing solar absorber systems for swimming pools are recovered by saved energy costs within 3 to 5 years; swimming pool heating cannot be more economical. For indoor swimming pools and for all-year operations we recommend a solar system with our high power CC-A/F EOXHcollectors.
