This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The solar cells produce electricity to the archives and to the adjacent preschool Tingsgården. at the Blekinge archive
The renovation and extension of the archive began spring 2014. The building project was completed in 2015. The existing building has been renovated and has received an addition. The actual archive now has a newly built area of 1,000 m2. The old archive building that has been renovated has an area of 600 m2.
Ronneby Municipality chose to invest in solar cells, when their buildings need to be able to produce their own electricity. In this case, the solar cells are located on the roof of the newly built archive building. The roof surface is 500 m2. The building is filled with archives, which means that electricity is needed during the summer to cool the building. In order to keep the records in the archive properly, it must not be too hot in the building. Even the older building with research rooms, conference rooms and offices is supplied with electricity from the archive. If the produced electricity is not used by the archives, it also supplies the pre-school, which is adjacent to the archive. Surpluses are sometimes sold to the grid.
The roof of Blekingearchive is a slab with slight slope. To optimize power generation, the solar cells are mounted on inclined positions. The advantage of such positioning is that it is that they are easy to move if you need to access any part of the roof.

Resources needed
The solar installation cost 52 000 Euro to build. 35% of the cost was financed through government grants, ie 18 000 Euro. Projecting was a small part of the overall planning of the new archive building. It has not needed any resources for the operation of the installation.
Evidence of success
The solar cell plant produces 35 MWh per year. The plant shows a good result and requires no maintenance.
Potential for learning or transfer
The solar cell plant is a good example of how solar energy can be produced for self-consumption and also contribute to electricity production for adjacent buildings. Since the archive has a cooling need during the summer, much of the electricity produced can be used directly in the business. The Blekinge archive is also a good architectural example where the solar cells fit well into the building.
