Solar System Inverters Types

Abstract

Population growth and economic development lead to an increase the global energy consumption from (60) million barrels per day in 1980 to (96.5) million barrels per day in 2021 and consumption is expected to increase and reach (104.1) million barrels per day in 2026. Fossil fuel causes the emission of greenhouse gases such as carbon dioxide and methane which are causes what is known as global warming and it is expected it will be exhausted within (40-60) years. Solar energy does not emit any pollutants and it is permanent as the sun is always shining, so it is necessary to develop the solar energy sector to reduce the risk of climate change and to make the air we breathe safer, also to produce energy locally and reduce dependence on foreign sources of energy. A solar inverter is one of the most important elements of the solar electric power system. It converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating 220V current (AC). This AC electricity then can be fed into your home to operate your appliances. Long-lasting solar power systems require a high-quality inverter with a robust convection cooling system. Low-quality inverters have failed in generating the required power. The efficiency and reliability of the inverter are considered one of the most important factors for the success of the solar system. The appropriate inverter is selected depending on the size of the solar system and the way it is connected to the main grid. The main types of solar inverters will be introduced in this article.
