The difference between grid and off grid solar generator system

The difference of Grid solar system and off grid solar power kits are different only the english word initially , now meant in the context of photovoltaics is an existing electricity grid. The two grid and off grid are essential for the photovoltaic.

A.      Grid solar System in photovoltaics

In a grid solar system is a photovoltaic system that produces electricity, this solar energy storage is then fed into an existing to public network. The solar backup power generator is NEBEM (the interconnected modules) an inverter necessary because in public power grids alternating current flows. In the grid solar systems, a distinction is in photovoltaics between different concepts:

1.       Grid Solar systems in which the photovoltaic system is used to supply a load parallel to the public grid. The decentralized solar energy storage is produced close to the consumer, so large transport losses can be excluded.

2.       Grid solar systems in which the photovoltaic system supplies the consumer an alternative to the public network. Here, the consumer is indeed also connected to the public network, the solar power backup generator is decentralized, so the draw-off produced. But instead feed surpluses into the public grid, these are primarily stored in the energy storage. This Grid Solar System provides mainly for a higher security of supply and is often used in weaker supply networks, as so-called backup system.

3.       Grid Solar systems supply consumers in parallel with the public network,the known grid solar  systems, such as are used in Germany and other industrialized countries. Grid systems that exert a so-called backup function are rather used in emerging markets or developing countries.

B.      Off Grid solar System in photovoltaics

In an off grid solar system is a stand-alone system. Such a photovoltaic system is therefore not connected to a public electricity grid and only works with energy storage. Such off grid solar systems or stand-alone systems have greater market share in the early days of Phovoltaik. Today they are primarily in cottages used, which are not connected to a public network because of the distance. Off grid solar power kits photovoltaic systems are also used in boats or caravans. Another application for Off Grid solar system photovoltaic is for example in the operation of desalination plants or water pumps. the market share is growing, especially in developing countries.
