“In a well-balanced grid-connected network, a solar array generates power during
the day which is then used in the home at night, which is especially important. Net
metering systems effectively allow solar generator proprietors to be charged if their
unit produces more power than is actually needed at home, which is generally very
important. A battery bank, charge controller and, in most situations, in a subtle
way, in off-grid solar applications, an inverter are kind of necessary components.
The solar array transmits some kind of direct current (DC) electricity through the
charge controller to the battery bank. The power is then essentially drawn from
the battery bank to the inverter which essentially converts the DC current into an
alternating real current (AC) which can be used for non-DC devices. Supported by
an inverter, in reality, arrays of solar panels can be built to meet the most demanding
electric charge requirements in an essentially large way. The AC current can be
used in a large way for driving loads in homes or particularly commercial buildings,
recreational vehicles and boats, remote cabins, cottages or houses, remote traffic
controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA
and quite a lot more” [13].
9.1.4 Photovoltaic Effect
Electricity can be produced directly from sunlight, through a process called the
photovoltaic effect, which is characterized as the generation of an electromotive
force as a result of ionizing radiation absorption. The photovoltaic effect can be
observed in virtually any junction of material with various electrical characteristics,
but the best performance to date has been from Silicon solar cells (Fig. 9.1).
9.1.5 Advantages and Disadvantages of Using Solar Panels
9.1.5.1 Advantages
Some advantages of using solar panels are: Solar Panel fuel supply is direct and
endless so no external fuel is needed, it is sunlight-cost-free, solar modules unlimited
life, quick response, and high reliability, can work in open and under high temperatures, short circuit inherently protected and safe under any conditions of load, free
from pollution, low maintenance, freelance job, simple operation, and no electrochemical reaction, and no liquid media, noise-free, because moving parts are not
present, no losses of AC to DC conversion because DC is directly generated, no loss
of transmission, as installed near the load, fits central, isolated and hilly areas, suitable
for loads/objects traveling. Since it is modular, there is provision for future capacity
expansion. It is capable of generating power from mili-watts to several megawatts.
From small electronic devices to large-scale MW power generation stations, it can
