Photovoltaic (PV) data Mersch/Luxembourg

The following PV data of 4 units is showing that this form of energy is technically mature. The units (approx. 130 m²) are producing the double in energy needed by a 6 person household. This includes the energy for heating (heatpump) and the electric car (Nissan Leaf). The data is aimed to help comparing different PV units, and to give an overview of the solar radiation in Luxembourg.

Data from two identical photovoltaic units with 4 kWp from 2002, one unit with 2.7 kWp from 2008 and one unit with 10 kWp from 2017:

  1. Unit (WG) 2002: 4 kWp, angle of inclination 45°, azimuth +15° (15° west)
  2. Unit (WP) 2002: 4 kWp, angle of inclination 30° azimuth -75° (75° east)
  3. Unit (WK) 2008: 2.7 kWp angle of inclination 19° azimuth +15° (15° west)
  4. Unit (AU) 2017: 2x5 kWp angle of inclination 10° azimuth +90/-90° (east/west)

Energy data for Luxemburg 2012 (german)

Getting Energy data for Luxembourg was not easy in the past. Fortunately for several years now, we can get data from the Luxemburgish regulatory authority and the statistical office The following course in German from the 12 class T2EE contains many information and graphics:
