The paper focuses on the possibilities of generating electrical energy by means of on-grid PV solar systems of 1 kW in the Republic of Srpska (Bosnia and Herzegovina). The paper proceeds to tackle with the le. . Economic development of countries at the end of the 19th and in the beginning of the 20th. . The paper [8] claims that in 2005 worldwide electricity generation was 17 450 TWh, out of which 40% originated from coal, 20% from gas, 16% from nuclear, 16% from hydro, 7% from o. . The PV solar system means a system by which the solar irradiation is converted into the electrical energy and is distributed to the direct and/or alternating current consumers. PV s. . Bosnia and Herzegovina has several levels of political structuring under the federal government level which are important to be considered in order to make some recommendation. . Republic of Srpska is located between 42°33′ and 45°16′ of the north geographic latitude and 16°11′ and 19°37′ of the east longitude and encompasses north and east part of the geo-ar. [pdf]
From all Balkan countries, it was found that Bosnia and Herzegovina has one of the largest potentials for the implementation of solar power plants. It was estimated that energy produced from solar power plants could be 70.5 × 10 6 GWh/year and the most suitable area is Herzegovina.
With around 60% of the land area, Bosnia and Herzegovina could have between 1.2 and 1.4 MWh/kWp of photovoltaic capacity compared to the world's solar potential. Compared to B&H and other Balkan countries, Serbia has a great potential for the implementation of solar energy.
In total, there are seven current and planned wind farms with an annual production of 936.17 GWh. From all Balkan countries, it was found that Bosnia and Herzegovina has one of the largest potentials for the implementation of solar power plants.
Concerning bioenergy, the greatest potential lies in wood residues, since forests are one of the main natural resources of Bosnia and Herzegovina. There are currently two biogas power plants, but there is no available data about biofuel and other biowaste utilization. 1. Introduction
Currently, there are 2 biogas power plants in Bosnia and Herzegovina, one in Banja Luka and the other in Lower Žabar near Brčko District. However, these are very small plants, with insufficient power and an impact on savings.
Immense potential also lies in Bosnia and Herzegovina's geothermal energy, however without significant interest of authorities in the development due to initial investments in geothermal heating, which are significantly higher compared to other conventional heating systems.

Solar energy is widely available in Armenia due to its geographical position and is considered a developing industry. In 2022 less than 2% of Armenia’s electricity was generated by solar power. The use of solar energy in Armenia is gradually increasing. In 2019, the European Union announced plans to assist Armenia. . According to the , Armenia has an average of about 1720 (kWh) solar energy flow per square meter of horizontal surface annually and has. . In Armenia, , or water-heaters, are produced in standard sizes (1.38-4.12 square meters). Solar water-heaters can be used for space heating, solar cooling, etc. In order to generate heat, they use solar energy from the Sun. Modern solar. . • • • • • • . As of April 2019 ten 1 MW strong solar stations are installed. Solar and wind stations account for less than 1% of total installed electricity generation capacities. In April 2019 it was announced that German company Das Enteria Solarkraftwerk will build. . One of the main factors preventing the development of solar energy in Armenia is the installation cost. . • • • [pdf]
In 2019, the European Union announced plans to assist Armenia towards developing its solar power capacity. The initiative has supported the construction of a power plant with 4,000 solar panels located in Gladzor. Solar power potential in Armenia is 8 GW according to the Eurasian Development Bank.
The 200-megawatt plant named Ayg-1 will be Armenia’s largest solar power plant with a capacity of around half of Armenia’s main energy generator, the Metsamor nuclear power plant․The plant is planned to be built in the Aragatsotn province in an area of over 500 hectares located in Talin, Dashtadem, Katnaghbyur and Yeghnik communities.
It is Armenia’s first large utility-scale and competitively-tendered solar independent power producer. The project will operate under a 20-year power purchase agreement and is expected to have a total cost of $55 million.
The reason for this is that average solar radiation in Armenia is almost 1700 kWh/m 2 annually. One of the well-known utilization examples is the American University of Armenia (AUA) which uses it not only for electricity generation, but also for water heating. The Government of Armenia is promoting utilization of solar energy.
Stressing that the investment program for the construction of a 200-megawatt photovoltaic power plant in the field of renewable energy in Armenia is the first step of mutually beneficial cooperation with Masdar, President Sarkissian hailed the agreement reached today on another 200 megawatt capacity.
The interlocutors also spoke about the opportunities for large-scale investments in the field of wind energy in Armenia. In November 2021, Masdar signed an agreement with the Government of the Republic of Armenia to develop a 200-megawatt (MW) solar photovoltaic (PV) plant. The Ayg-1 project will be Armenia’s largest utility-scale solar plant.

The Mubuga Solar Power Station is a grid-connected 7.5 MW power plant in . The power station was constructed between January 2020 and October 2021, by Gigawatt Global Coöperatief, the Netherlands-based multinational (IPP), through its local subsidiary Gigawatt Global Burundi SA. The off-taker for this power station is Régie de production et distribution d’eau et d’électricité (), the Burundian electricity utility. [pdf]
Burundi has natural conditions favourable to the sustainable use of water and solar energy or wind power. The solar potential of Burundi is very interesting. The average annual power received is around 2000 kWh / m² per year, equivalent to the best European regions (southern Mediterranean).
The power station is located in the settlement of Mubuga, in the Gitega Province of Burundi, approximately 15.2 kilometres (9 mi), northeast of the city of Gitega, the political capital of that country. This power station is the first grid-connected solar project developed by an IPP in Burundi.
Another estimated 25-50 people were hired to operate the power station. In May 2023, Evariste Ndayishimiye, the president of Burundi toured the solar farm and personally gave his approval for the power station's capacity to be expanded to 15 megawatts.

A 25-year power purchase agreement (PPA) governs the sale of electricity between Gigawatt Global Burundi SA and REGIDESO. The engineering, procurement and construction (EPC) contractor was Voltalia of France, which was also awarded the operations, management and maintenance contract.
