The operation of a stand alone system

A Solar Cell System consists of only three basic units, which makes it a very reliable energy source

The solar radiation creates a current in the Solar modules (1). The effect depends on the size of the Solar modules and the intensity of the solar radiation. This current is led through the Solar Charge Controller (2) to the Battery Bank (3). Hereby the energy can be stored and used when needed.


Solar modules
A Solar modules consists of a number of Solar Cells made of silicon plates. When the plates are exposed to solar radiation, a current is produced. This current is later used to operate electrical devices Volt . Note that you need an Inverter to be able to use normal 220 AC installations.

Solar Charge Controller
The Solar Charge Controller is the operating system of the Solar Cell System and it’s task is:

to prevent overcharging of the Battery Bank, to ensure optimum charging rate, to manage the different consumption and charging rates.

Battery Bank
The Battery Bank stores the current created by the Solar modules. To reach an optimum use of the system the Battery Bank must be able to:

charge even low currents, ensure a large number cycles of charges and discharges, endure frost condition in cold areas, have a small self-discharge rate.
