JUSTIFICATION OF INVESTMENT IN THE CONSTRUCTION OF SOLAR POWER PLANTS IN AREAS WITH CONTINENTAL CLIMATE
Investment in the construction of solar power plants is also justified in areas with a continental climate.
Continental climate
Continental climate is a
type of climate that occurs in the continental area of the central part of
the northern hemisphere. It is an area in the zone of westerly winds; similar
climates exist on the east and southwest coasts of the same continents and in
other higher parts of the world. This climate is characterized by harsh and
cold winters, at least cold enough to keep the snow cover for a longer period
and relatively dry summers with little rainfall, while some eastern coasts,
like the North American coast, are much rainier in the summer. Only some areas
of Iran, Turkey, and Central Asia show maximum amounts of snow during the
winter that melts in early spring and results in short-term flooding.
These regions usually have
either forests or meadows with tall grass as a natural cover and include some
of the most productive areas in the world. These types of climates have at
least three months when the temperature is higher than 10 ° C and winters with
at least one month when the temperature is lower than 0 ° C.
In such climatic zones, the
average summer temperature is between 21 ° C and 32 ° C during the day and between
10 ° C and 18 ° C during the night. The average winter daytime temperature is
from -12 ° C to 7 ° C, and the nighttime temperature is from -23 ° C to 4 ° C.
Spring temperatures begin to occur in early March in the southern parts, and in
the northern in mid-April. The annual rainfall in these zones is usually
between 61 cm and 122 cm. Most precipitation is during the winter, in the form
of snow. The sunniest periods are in summer, and the most cloudy and gloomy in
winter, although winters can sometimes be full of sunny days.
Justification of investment in the construction of solar power plants in the northern part of Bosnia and Herzegovina
Bosnia
and Herzegovina is one of the most suitable locations in Europe when it comes
to solar energy radiation. According to available data, the sun annually
transmits, on 1m2 of horizontal surface, in the north of Bosnia and Herzegovina
about 1,240 kWh of energy, and in the south of the country about 1,600 kWh of
energy. For comparison, in Germany, which is expected to be one of the leading
producers of solar energy, this amount is 1,000 kWh per year.
The
northern part of Bosnia and Herzegovina is an area with a continental and
temperate continental climate.
Since
there are still a small number of power plants in Bosnia and Herzegovina that
produce green energy, such projects for the production of electricity are
supported by various incentive systems from relevant institutions and local
communities.
Governments at various levels have
prescribed rules on the guaranteed purchase price of alternative energy for a
period of 12 years.
The price in the first 12 years,
including a trial run lasting 6 months to 1 year, is calculated as follows:
Gc = Rc x C
Rc- average production price of
electricity in B&H
C- incentive price for 12 years
In
this way, we come to the key element for assessing the cost-effectiveness of
building a photovoltaic power plant.
The
most favorable incentive purchase price of electricity for the construction of
a photovoltaic power plant is for such micro plants with a limit power of up to
23 kWp.
Considering
the location, existing layout and types of buildings, the optimal technical
performance of the solar power plant is the installation of solar panels on the
south sides of the gable roofs of business or residential buildings on aluminum
purpose-built substructures. Considering the available effective roof area, the
amount of potential investments and the incentive purchase price, the
investor's commitment should go in the direction of building a solar power
plant with a limit power of 23 kWp.
The average annual production of
23,200 kWh of electricity is expected from a solar power plant with an
installed capacity of 23 kWp. If we start from the known parameters, based on
the guaranteed purchase price of alternative energy for a period of 12 years,
we get:
Gc = Rc x C
For a solar power plant with an
installed capacity of 23 kWp with an annual production of 23,200 kWh with the
currently guaranteed price, we get that the expected income from the production
of electricity:
Gc = 0.21 EURO / kWh- unit price
0.21 KM x 23200 kWh = 4872 EURO -
annual revenues of the solar power plant based on the production of electricity.
The
only significant disadvantage of solar power plants, if it can be called that,
is the relatively large initial investment (and the construction of other
plants requires investment), but from year to year with declining prices of
basic equipment it decreases, while after the construction of photovoltaic
power plants running costs are minimal.
In
this part, we will deal with the approximate investment costs of the solar
power plant in question, assuming that the investor owns a facility in a
suitable location for the construction of the power plant, whose roof has a
favorable slope with good orientation.
We will make an assessment depending on the choice of
photovoltaic panels as the most important items in the investment:

By simply comparing the value
of the investment costs with the total estimated annual income from electricity
production, we get that the investment for the construction of a solar power
plant with an installed capacity of 23 kWp pays off within 4.0 - 5.0 years when
current operating costs and costs are taken into account. registered
electricity generation companies. Based on the shared experiences of other
electricity producers and the existing norms for current maintenance, we have
predicted a 2% value in money from total annual revenues.

Conclusion
Therefore,
since the profitability of the investment in question is estimated at 4.0
years, ie 5 years, we conclude that it will generate significant revenues in
the next 8 years, ie 7 years, with an extremely favorable incentive purchase
price, while in the remaining period until the end of service life (remaining
13 to 18 years) to generate income at guaranteed reference prices.
Based
on the presented indicators, it can be concluded that this is a profitable investment,
which is primarily a safe investment with the desired product, a secure
customer and a secured price for a longer period. Also, the investment in
question represents a reliable and respectable source of financing in the long
run, as well as a contribution to energy efficiency.
