Solar Power Generating Systems

Off-Grid or Standalone Solar Power System

A stand-alone solar power system, also known as off-grid solar power system, is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. Typical SAPS include one or more methods of electricity generation, energy storage, and regulation. Stand-alone solar power systems are independent of the utility grid.

Storage is typically implemented as a battery bank, but other solutions exist including fuel cells. Power drawn directly from the battery will be direct current extra low voltage, and this is used especially for lighting as well as for DC appliances. An inverter is used to generate AC low voltage, which more typical appliances can be used with.

Grid Connected Solar Power System

A grid-connected Solar power plant is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected solar power plant consists of solar panels and one or several inverters. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. Unlike stand-alone solar power systems, a grid-connected solar power system rarely includes an integrated battery solution, as they are still very expensive. When conditions are right, the grid-connected solar power system supplies the excess power, beyond consumption by the connected load, to the utility grid.

Hybrid Solar Power System

A hybrid solar power System is combined of above two systems. It will use solar power when the sun is available. It will also charge the battery and in the absence of grid-connected power, it will use the battery power as the source of power. But the cost of such system will be more and it will effect the overall payback period of the project.
