Strategy recommendations for increasing solar energy investments

The aim of this study is to determine the right strategies for increasing solar energy investments. In this context, articles with “solar energy” in their titles for 2020 and 2021 in the Web of Science database are included in the review. In this context, 933 articles are identified. After that, the abstracts of the mentioned articles are analyzed by data mining method. To achieve this aim, the N-gram application over the KNIME program has been taken into consideration. In this process, the most frequent double words and triple words are determined. Thanks to these prominent word groups, it has been tried to determine the factors that are important for solar energy investments. The biggest contribution of this study to the literature is the simultaneous consideration of very comprehensive studies to present correct policy recommendations to solar energy investors. By examining all current studies on solar energy investments, it will be possible to determine the right strategy proposals.
