2. Function description:
(1)Solar cell module
    Solar cell module is the major part in the solar power system, also is the most valuable
part in the system, it converts the solar radiation energy into DC energy;
The solar cell module is a solar generating device that converts the solar energy into DC
energy directly. According to user's requirements to the power and voltage, it can be prepared
into single solar cell module or solar array that is composed of many solar cell modules by
means of serial connection (to meet the voltage requirement) or parallel connection
(to meet the current requirement). It is featured with high power-to-area ratio, long service life and high reliability, in 20 years of service life,
its output power decrease generally not exceed 20%.
Generally speaking, the generated energy of solar cell module will scale up along
with the increase of sunlight intensity, and reduces slightly along with the increase of
surface temperature of the solar cell module. It's peak power Wp means the value of
Imax*Umax when the sunlight intensity is 1000W/M2, AM is 1.5, panel surface temperature
is 25ºC.
Along with the temperature change, the current, voltage and power of solar cell module
will change correspondingly, so the designer must take the voltage negative temperature
coefficient into consideration when connecting the solar cell modules in series.
(2)Solar charging and discharging controller
It is also called "photovoltaic controller", it regulates and controls the electric energy
generated by the solar cell modules, and charges the storage batteries to the largest extent,
while, carries out overcharge and overdischarge protection to the storage batteries.
In places where have large temperature difference, the solar controller also should have
function of temperature compensation.
The solar controller is mainly used to regulate and control the DC energy generated by
the solar cell modules, it also has intelligent management function to the battery charging
and discharging. In places where have large temperature difference, the solar controller also
should have function of temperature compensation.
Select suitable solar controller according to the DC voltage class of system as well as the
power of solar cell modules, the frequently used voltage classes of solar controller are
DC12V, 24V, 48V, 110V, 220V.
(3)Storage battery
It is mainly used to store energy for nights or rainy days, arrange the number of
serial/parallel connected storage battery according to system's DC voltage class; try to use
1-2 groups of storage battery of large capacity, the frequently used specifications are
12V and 2V;
Please follow these principles when connecting the storage batteries in parallel: same
model, same specification, same manufacturer, same batch, install and use at the same
time.
(4)Off-grid inverter
It is a core component in the off-grid power generating system, it converts the direct current into alternating current for AC
loads. In order to improve the overall performance of solar generating system, guarantee
long-term stable operation of power station,
it is very important to choose inverters of high performance indexes.
Off-grid inverter is an important device in the solar generating system,
model selection of the inverter depends on load characteristic
(such as resistive, inductive or capacitive) and magnitude of load power.
