Solar energy is the most abundant, inexhaustible and cleanest of all renewable energy resources to date. The power from the Sun intercepted by the Earth is about 1,8 × 1011 MW, which is by many times bigger than the present rate of all the energy consumption. Solar energy is one of the best renewable energy sources with the least negative impacts on the environment.
One of the most popular techniques of solar energy generation is the installation of photovoltaic (PV) systems using sunlight to generate electrical power. There are many factors affecting operation and efficiency of the PV based electricity generation systems, such as PV cell technology, ambient conditions and the selection of required equipment. There is scarce study that presents all factors affecting efficiency and the operation of the entire PV system.
Electricity from photovoltaic cells can be used for a wide range of applications, from power supplies for small consumer products, to large power stations feeding electricity into the grid. PV solar system can function independently of the electric power network (off grid) or it can be connected to it (on grid). Depending on the components that comprise it, an off-grid PV system can supply the consumers with DC current or AC current. An offgrid PV system that gives consumers DC current is composed of solar cells, batteries and batteries charge controllers. An off-grid PV system that provides consumers with AC current consists of solar cells, battery charge controllers, batteries and DC to AC inverter. On- grid PV systems consist of solar cells, inverter, monitoring system, distribution boxes, switches and related connections. On-grid PV systems are most frequently used for PV solar plants, residential and office buildings, etc.
PV solar plants mostly use solar modules made of monocrystalline and polycrystalline silicon, and rarely, modules made of thin film materials such as amorphous silicon, CdTe and CopperIndium-Diselenide (CIS, CuInSe2). Depending on the climate conditions of the given location, fixed PV solar plants, one-axis and dual–axis tracking PV solar plants are being installed worldwide. Fixed PV solar plants are used in regions with continental climate and tracking PV solar plants are used in tropical regions.
Different countries have different solar energy policies to reduce dependence on the fossil fuels and increase domestic solar energy powered energy production. The solar energy sector in Bosnia and Herzegovina is not fully developed yet. Our goal is to become and remain the biggest private producer of solar energy in Bosnia and Herzegovina, while providing clients with turn-key projects globally.
