The first type: On-grid solar energy systems:
On-grid systems generate energy when the electricity grid is available (electrical facilities meters) and work to reduce electrical consumption. These systems can also export the excess energy produced to the electricity grid for use in the following months or sell it to electricity company under long term contracts. These systems contain solar panels, inverters, cables and protection circuit breakers.
The second type: Off-grid solar energy systems:
Off-grid systems are completely separate from the public electricity grid. They are fully independent and self-sufficient systems that cover 100% of the energy needs throughout the day. These systems are used in remote areas that far from the government electricity grid and in applications Which depends on diesel generators. These systems contain solar panels, inverters (transformers), batteries, cables and protection circuit breakers.
The third type: hybrid solar systems:
Hybrid systems combine the advantages of both on-grid and off-grid systems as they allow you to store your solar energy in batteries for use when the public electricity grid is out.
The hybrid solar system can be composed of solar plants to produce electricity during the daytime and at night generators are relied upon instead of batteries in the case of large loads. This type of hybrid stations is considered an economical solution to save the fuel consumption used to operate generators and the fuel saving rate reaches 60%. In addition to reducing dependence on the generator, thus increasing its service life and reducing maintenance work. This type of station does not require batteries for storage due to the combination of solar systems and the generator.
Fourth type: solar energy systems for agriculture and irrigation:
Solar energy systems for agriculture and irrigation are completely independent from the public electricity grid, as it operates all types of pumps during the daytime and directly, such as submersible and surface pumps. It is considered as an alternative system to traditional diesel generators to run irrigation systems on farms.
