Types of Solar Power Generation Systems

 


Stand-Alone

This is an independent system that does not use any electricity from the electric power company. It accumulates electric power that is generated by the solar cells in a rechargeable battery during the daytime, and supplies that electric power according to its demand.

Terms frequently used about Solar Power Generation

 

PV     This is an abbreviation of “Photovoltaic”, and it means “Solar Cell “ in general.
“Cell”, “Module”, “Array”

Cell   refers to a smallest unit that functions as a solar cell. It is a thin silicon plate, measuring
about 10cm, 12.5cm or 15cm square or round in general (in a crystal system).

Module refers to an arrangement of cells that are connected together and housed in a
package so that voltage can be taken out conveniently. A module is the smallest unit
or construction work.

Array refers to an arrangement of modules embedded on a mounting base so that higher
Amounts of electricity can be taken out.

 

 Power Conditioner

AC is generally used in households, offices, factories, etc., but a solar cell or rechargeable battery outputs DC.
Accordingly, in order to practical use electricity that is generated by a solar cell or that from a rechargeable battery, it is necessary to convert DC into AC.
The equipment for making such conversion is a “Power Conditioner“. In addition, the Power Conditioner not only works to convert DC into AC, but also controls the frequency, voltage, current, phase, effective and ineffective power, synchronization, output volume (fluctuations in voltage, higher harmonic waves), etc. The power conditioner has the following functions:
“Automatic Stop of Operation”, “Max. Power Follow-up Control”,
“Independent Operation Prevention”, “Automatic Voltage Adjustment
