PV POWER SUPPLY FOR REMOTE VILLAGE "RAMBLA DEL BANCO"

Objetivo

Test of new pv components and system technology.
Electrification (lights, cooling, TV) of remote mountain village, that had no electricity before.
Provide extra power for production and finishing industry.
The system started operation in October 1990. Load management (through the LMS system) is not yet necessary because of low consumption.
The abundance of energy continues even after year because people are moving away from the village and the remaining ones have no money to buy ac-appliances.
The central battery had to be replaced in 1992 (by Bosch, successor of FEMSA).
The cost per unit of energy is calculated to be 3.5 Ecu/kWh for the demonstration project and 2.3 Ecu/kWh for a replication.
A central pv system with some innovative ideas : electronic power management (reduces inverter peak power), controller for outdoor lighting, special fluorescent lamps, lightning protection.
AC and DC power available in the houses : AC during the day for refrigerators (with cold storage for the night), washing machines, kitchen appliances and for charging the decentralized batteries.
DC during night for lights and television. Some modular street lamps, type SELSET 18W.
