Purpose: The purpose of this study is to investigate whether solar cells could have supplied to the energy needs of a construction project during its building phase and see which advantages and disadvantages this would have brought the company.

Method: A case study has been carried out on a selected project with help from a selected company. The data collection methods that have been used for the empirical work have been literature research, document analysis, calculations from a solar cell simulation program and interviews.

Findings: The results of the study answer the questions of the study and show how much solar cells could have contributed to the project, relative to the project’s electricity use. The findings also show how the placement of solar cells on the barracks and tool containers could have been carried out in order to retrieve as much energy from the sun as possible.

Implications: The conclusion of this study is that the solar cells require a considerable amount of space, and therefore the case study project could not have used solar cells only to cover the project’s energy needs. Solar cells require maintenance and are a great cost to the companies involved, but can also promote the company’s reputation and contribute to a more sustainable society.

Limitations: The study has been limited to one construction project of a tennis arena located in the Stockholm region, which was built by a construction company between August 2016 and February 2018. The study only takes the electricity usage during the production phase into account and the aim were to see if electricity from solar cells in the construction area could have contributed to the electricity needs during this period. The focus of the report is not costs, use of batteries, or regulations concerning the project, but these aspects are briefly covered.
