Solar power generating systems
Off-Grid / Standalone Solar Power System
A stand-alone (off-grid) solar power system is an off-the-grid electricity system for locations not fitted with an electricity distribution network. Typical systems include one or more methods of electricity generation, energy storage and regulation, and are independent of the utility grid. Storage is typically a battery bank; power drawn directly from the battery is extra-low-voltage DC, used especially for lighting and DC appliances. An inverter generates low-voltage AC for more typical appliances.
Grid-Connected Solar Power System
A grid-connected solar power plant generates electricity and is connected to the utility grid. It consists of solar panels and one or several inverters, ranging from small residential and commercial rooftop systems to large utility-scale stations. Unlike stand-alone systems, it rarely includes an integrated battery, as they are still very expensive. When conditions are right, the system supplies excess power - beyond the connected load - to the utility grid.
Hybrid Solar Power System
A hybrid system combines the two above. It uses solar power when the sun is available, charges the battery, and - in the absence of grid power - uses the battery as the source of power. The cost of such a system is higher and it affects the overall payback period of the project.
