PV RURAL ELECTRIFICATION OF 79 ANDALUSIAN DWELLINGS

Ziel

To demonstrate that isolated rural areas in regions of high annual irradiance, unconnected to the grid can be electrified by photovoltaic systems. Detailed load analysis in the different sites have been made and the sociological effects in the small rural communities have been studied. (Acceptance of electrification).
The systems operate since October 1988 (on DC) and since October 89 (on AC), but there were previous and subsequent problems with the inverters, especially at the Rio Madera (!). Two sites (I and III) are now to be connected to the grid and the pv systems shall be possibly used for grid boosting.
The knowledge obtained through this project by the contractor (Compania Sevillana de Electricida) to solve technical and social problems is a valuable experience for future pv projects.
79 dwellings are electrified with 39 individual and centralised sub-systems. At the five locations different subsystems are installed.
220 AC: at sites I, II, IV, V: centralized; at site III: individual.
24 V DC: at site IV, V: centralized; at site III: individual.
12 V DC: at site II: centralized.
I: RIO MADERA. 27 houses. At that site, with grouped houses, a new grid has been installed. Local grid: air lines, typically several hundert meters long.
II: LOS MORALEJOS. 17 houses. The houses have already individual.
12 V DC supplies, which have been modernized. An additional grid has been installed.
III: PRADOS DELLA PRESA. 15 houses. At this site with isolated houses, 12 houses have been equipped with an autonomous 24 V DC supply and a 220 V AC supply, three houses with 12 V DC supply. No local grid is installed. IV: FUENTE DE LA HIGUERA. 14 houses. The existing, autonomous 12 V installation has been replaced by a 24 V DC grid and a supplementary grid has been installed.
V: LA CANALICA. 6 houses with systems similat to site IV.
Nr. of subsystems : I:3. II:1(central)+17 indiv. III:15 indiv. IV: 3. V:1
Power of subsystems : I: 2.7+3.6+3.6 = 9.9 kW. II: 2.4 kW +0.8 kW
= 3.2 kWp. III:4.6 kW.
