Domestic installations monitored by Rtone in the South of Belgium. In this region, the density of these installations is very high.

Neighbor, Could you tell me my solar irradiation?

Novelty! Neighboring installations as irradiation sensors

¿How do I know my irradiation?

Global Tilted Irradiation from weather conditions

Loreto González-Bonilla. EUREC Awards, October 2014, Brussels, Belgium 7

Cloud cover information

Cloud cover information

1. Irradiation under clear-sky conditions(Perez-Ineichen)

2. Irradiation under real state of the sky (including cloud cover)

(Myers model at NREL)

3. Global Tilted Irradiation(Hay model)
