Abstract
The demand for energy is enlarged nowadays while the existing energy sources have decreased.
So, efforts were adopted to search for alternative energy. One of the most common kinds of alternative
energy is solar energy. The purpose of this work is to estimate the cost of building a standalone
photovoltaic system to generate electricity for-farmer house and farmland in a remote area in Karbala
City, Iraq, and compare this cost with the other generator sources. Methodology: First, the load, which
is the central part of the design, must be calculated from the ordinary electrical devices usually used in
a farmhouse and farmland, especially in Karbala. According to this load the design of the standalone
photovoltaic system was achieved by selecting the proper components such as solar photovoltaic (PV)
modules, batteries, solar charge controllers, and inverters. In addition, the total cost of the construction
of the system and the annual maintenance cost will be estimated, and the cost will be compared with
another kind of generator using gasoline. Simple manual calculations were used in all the theoretical
design step Finding: The proposed Stand-alone system will satisfy approximately the energy for entirely
the home applications chosen at complete load, at daylight, and provides about 2 days at days of
autonomy for (50%) depth of battery discharge. The total cost of the system is about 15000 $, and the
unit energy cost is 0.09 $/ Kilowatt-hour (KWh . ( Research implications: The cost of construction of a
stand-alone photovoltaic system for a city consisting of a large number of houses will reduce the cost
for one house and also enhance the stability of the demand load.Originality value: Using a solar-powered
system is a suitable choice for a house in a remote area in Kerbala city instead of an oil generator for
both cost and environment, and farmers must know that.
