Shortly after signing the collaboration agreement with the world’s largest producer of flat solar collectors, Aalborg CSP received the first order to deliver a 1.9MWth solar district heating plant consisting of GREENoneTEC flat panels in the southern part of Denmark.

Client:      Solrød Fjernvarme a.m.b.a.
End user/Owner:        Solrød Fjernvarme a.m.b.a.

Status:   Under construction

Solar heating technology matching the customer's energy needs

Aalborg CSP has investigated the potential to use solar heating to reduce the Danish district heating plant’s (Solrød Fjernvarme a.m.b.a.) natural gas dependency as well as to stabilize energy prices. To match the client’s energy requirements at the lowest possible cost, Aalborg CSP’s technology selection favored a 2,569m2 flat panel system along with a 1,250m3 heat storage accumulation tank providing 350 households with sustainable heating.

The company’s first flat panel project was secured shortly after signing the distribution agreement with GREENoneTEC Solarindustrie Gmbh, the world’s largest producer of flat plate solar collectors. The aim of this agreement has been to strengthen Aalborg CSP’s solar portfolio and to provide the district heating clients with more technology alternatives suitable to their individual energy needs. 

A competitive solar plant

The plant’s competitiveness is well illustrated in the fact that Solrød Fjernvarme’s natural gas dependency as well as the citizens’ heating bills will be reduced.

“Today we use natural gas to provide heating for the inhabitants of Havdrup, but when the new solar field goes operational it will be able to cover 28% of the town’s heat demand. At the same time, our consumer prices are expected to be lowered which not only provides us with a more sustainable solution but also with a more economical one” – says Kaj Holm Rasmussen, Operation Manager of Solrød Fjernvarme a.m.b.a.

The solar plant will consist of 13 rows of GREENoneTEC collectors from the GK 3003 series with up to 20 collectors placed in one row. The 13,3m2 optimized panels have shown the highest performance among all known mass-produced large-scale solar collectors on the international market. This enables the solar energy system in Havdrup to become one of the most efficient flat panel fields in the country.

Besides offering a cost competitive solution for heat production, the solar plant also avoids the emission of at least 233 tons of COannually.

Reduced time for construction and installation

Construction of the plant was commenced in the middle of September. The mounting system, which permits time-saving installation by crane, and the hydraulic connection considerably reduce the overall time and effort required to install the solar panels. It is expected that the solar energy system together with the storage tank are installed in short five weeks.
