RECOMMENDATIONS FOR SMALL RENEWABLE ENERGY AND HYBRID SYSTEMS FOR RURAL ELECTRIFICATION - PART 7-1: GENERATORS - PHOTOVOLTAIC ARRAYS
This Malaysian Standard specifies the general requirements for erection and operation of PV arrays in decentralized rural electrification systems.
This Malaysian Standard gives requirements for d.c. voltages below and above 120 V. However for rural electrification projects it is strongly recommended to choose a voltage in the range of extra low voltage, taking into account the assumed skills of the operators,
installers and users. Nevertheless, designers have to be aware that decreasing the voltage means increasing the current and thus transferring voltage hazards to current risks (risk of fire, etc.).
The following PV array configurations are considered:
a) single string of modules;
b) multi-string PV array; and
c) PV array divided into several sub-arrays.
Direct current systems, and photovoltaic systems in particular, pose various hazards in addition to those derived from conventional a.c. power systems, for example the ability to produce and sustain electrical arcs with cu
