Solar Ressource Assessment
In order to design profitable solar power plants, It is essential to measure the local irradiation. Depending on the type of your planned solar power plant
- PV (Photovoltaic) or
- CSP (Concentrated Solar Power)
different measurements are necessary:
|
|
Measurement instrument | Application | |
| GHI | Global Horizontal Irradiation | Pyranometer, reference cell | PV and CSP |
| GTI | Global Tilted Irradiation | Pyranometer (tilted), reference cell (tilted) | PV |
| DHI | Diffuse Horizontal Irradiation | Rotating Shadowband Irradiometer, Pyranometer with shadow ring or ball | PV |
| DNI | Direct Normal Irradiation | Pyrheliometer installed on Sun Tracker, Rotating Shadowband Irradiometer | CSP and large PV power plants |
