A work on the review of integration of solar power into electricity grids is presented. Integration technology has become important due to the world's energy requirements which imposed significant need for different methods by which energy can be produced or integrated, in addition to the fact that integration of solar energy into non-renewable sou. IntegrationSolar powerElectricity gridGrid connectionsSolar-grid integration is a network allowing substantial penetration of Photovoltaic (PV) power into the national utility grid. This is an important technology as the integration of standardized PV systems into grids optimizes the building energy balance, improves the economics of the PV system, reduces operational costs, and provides added value to the consumer and the utility. Solar-grid integration is now a common practice in many countries of the world; as there is a growing demand for use of alternative clean energy as against fossil fuel. Global installed capacity for solar-powered electricity has seen an exponential growth, reaching around 290 GW at the end of 2016. According to IRENA's Renewable Energy Capacity Statistics (2017), currently China is the leading producer of solar power followed by Japan, Germany, and United States. Also, solar installed capacity by region has Europe leading with over 98.8 GW, closely followed by Asia with 92.3 GW. Africa is least in solar installed capacity with about 1.92 GW,,. However, Africa is highly abundant in solar radiation with most of the African countries receiving a very high amount of bright sunlight resource of days per year that can be used for electricity generation. Notable areas include the deserts of North & West Africa like Egypt, Nigeria and some parts of Southern and East Africa which receive long periods of sunny days with a very high intensity of irradiation. According to the IRENA's Renewable Energy Capacity Statistics (2017), Africa has nearly r. Basically, there are two types of solar power generation used in integration with grid power - concentrated solar power (CSP) and photovoltaic (PV) power. CSP generation, sometimes known as solar thermal power generation, is much like conventional thermal power generation that converts thermal energy (steam) into electricity. However, Photovoltaic. Solar-Grid integration is the technology that allows large scale solar power produced from PV or CSP system to penetrate the already existing power grid. This technology requires careful considerations and attentions including in areas of solar component manufacturing, installations and operation. The levels of solar energy penetration must be interconnected effectively onto the transmission grid; such interconnection requires an in-depth understanding of the effects on the grid at various points.Photovoltaic plant which uses PV modules to feed into the grid essentially consists of different components, but basically the inverter is the most important component for integration. Other components include PV generator (solar modules), Generator junction box (GJB), Meters, Grid connection, and DC and AC cabling as shown in Fig. 1. Inverters play a crucial role in any solar energy system and are often considered to be the brains of a project. An inverter's basic function is to “invert” the direct current (DC) output into alternating current (AC) which is the standard used by all commercial appliances. Inverters are required to supply constant voltage and frequency, despite varying load conditions, and need to supply or absorb reactive power in the case of reactive loads. Apart from inverting, inverters do reconcile the systems with each other and to feed the solar power into the grid with the highest possible efficie.
