Grid-Tie Systems

Grid-Tie Overview

A grid-connected PV power system is an electricity generating solar PV power system that is connected to the utility grid. A grid-connected PV system consists of solar panels, one or several inverters, a power conditioning unit and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. Unlike stand-alone power systems, a grid-connected system rarely includes an integrated battery solution, as they are still very expensive.

These systems use the available energy provided by the sun and directly converts it to usable power ready of instant consumption.

Systems must be designed in such a way the that the power production does not exceed the load during any time of the day as current grid feedback is limited to a small number of municipalities and is not in use in the greater Johannesburg area. The systems design is modular and can be extended once it becomes feasible to feed power back to the gird.

Grid-tied PV Systems have the shortest payback periods of all PV solutions and these are the most financially viable option if cost reduction is the main aim for the Business.
Systems are modular, and systems can be expanded on as and when required.
