Solar Resource and Photovoltaic Potential in Indonesia

This report presents results of the solar resource mapping and photovoltaic power potential evaluation, as a part of a technical assistance, implemented by the World Bank, for the renewable energy development in Indonesia.

The study has two objectives: (i) Improve the awareness and knowledge of resources for solar energy technologies by producing a comprehensive countrywide data set and maps based on satellite and meteorological modelling. This report evaluates key solar climate features, and geographic and time variability of solar power potential in the country. The outcomes are supported by explanation of the methodology and evaluation of the data uncertainty. (ii) Provide support information for installation of meteorological stations in Indonesia by identifying and evaluating the most feasible areas. The data used in this report are based on the satellite and meteorological models. Due to insufficient number of high accuracy solar measurements in Indonesia, the data and the outcomes published in this study have higher uncertainty, compared to other regions. The uncertainty of the model outputs, in Indonesia, can be reduced by acquiring high quality measurements at several meteorological stations with specialised solar-measuring equipment. Satellite-based and meteorological models are used for computing solar resource and meteorological data that are suitable for production of high-resolution maps and for use in Geographical Information Systems (GIS). A set of primary data parameters is discussed in the study.The report also provides an indicative analysis of regions and areas where deployment of solar measuring stations could take place. These stations would contribute to the validation of the models and reducing the data uncertainty. Once at least one year of measurements is available the data can be used for adaptation of solar and meteorological models and for detailed analysis of solar climate at representative sites.
