How detailed do external expertise, equipment and infrastructure (for investment) have to be defined in the AF? For instance, the small scale investment is a small solar plant – do we have to input costs for every part of the equipment (solar panels, inverters,…) or can we put down a sum of costs for equipment in one line?

The budgeted elements should be as detailed as possible, provided that they remain clearly recognizable for the assessment of the project activities. One line can be used with detailed information (e.g: 1 small solar plant including solar panels, inverters, …).
