Frequently Asked Questions
This measurement is carried out through global direct measurements using pyranometers in real-time. We placed dozens of pyranometers across the islands of Java, Madura, and Bali to provide accurate results.
Assessments or studies related to PV power plants always begin with collecting/analyzing irradiation data from a location. Generally, irradiation data is needed to determine the potential energy that can be generated by the plant from an area and perhaps compare it with others. In addition, this data can also be used for various other study purposes. Irradiation data is useful both for academics, research, government, and private parties engaged in the development/study of PV power plant.
We placed dozens of measurement devices all over Java, Madura, and Bali. But there are maybe times when you need irradiation data at a location where our devices are not on that exact location. Interpolation will be done by looking for the closest devices around your point at a certain radius. However, the position of our devices is spread evenly so that the interpolated data you will get is going to be quite accurate.
In the search feature on the Map page, you can find the location you want by entering the coordinates (not the address) of the location you needed. The format used is DD format (Example: -6.2441, 106.8254). After entering the coordinates and pressing enter, the system will show your location and run the interpolation if needed.
You will get a Microsoft Excel Open XML Spreadsheet (XLSX) data file-type, which appear in the form of row and column of data if you open it in a number processing software such as Microsoft Excel.
Yes, you can use this data for any purpose. We strongly support academics to conduct research in the field of renewable energy. You can mention indonesiasolarmap.com in your study report so that you can engage your school or campus environment to research in the PV power plant field as well.
We provide 4 types of access, which are free, silver, gold, and platinum access. What distinguishes these four types of access is the type of availability of the data density when downloading data. This data density may be useful depending on the purpose for which you download this irradiated data.
We dedicate this data to Indonesia, this data is available to use for any purpose. Meanwhile, access classes that need to be obtained with donations are intended solely as a source of funds for operation and maintenance.
The method we use is real-time measurements at dozens of locations that were taken in 2021 & 2022 across Jawa, Madura, and Bali. This platform is the only one that does this in Indonesia recently. Most likely the platform you are referring to has a different data collection/calculation method or data retrieval date.
