South Africa outdoor power supply parameter configuration

How do I estimate a PV system in South Africa?

All of South Africa is covered, so estimations can be done simply by entering the coordinates of the prospective site. Other information to be entered includes the nominal PV system power, module orientation, and slope and mounting type. In addition, thin film modules or crystalline modules can be selected.

What is the minimum operation voltage in South Africa?

For most regions of South Africa, a value of 0°C can be used for the calculation. The minimum operation voltage is the MPP voltage at the highest expected module temperature. There is no temperature coefficientgiven for MPP voltage behaviour in most data sheets.

How does a PV system work in South Africa?

The energy produced by a PV system can be consumed in the same household or fed to the public grid and then consumed by another user. Because of the lack of or low feed-in tariffs, the most economical way to operate a PV system in South Africa is to use most of the PV energy in the same household.

Does South Africa have regulations on PV installations?

South Africa still has a lack of regulations and standards regarding PV installations. Nevertheless, existing regulations must be adhered to. In the NRS 097-03, the maximum size of a PV installation connected to a certain feeder is stipulated.

How is irradiation optimised in South Africa?

The unshaded annual irradiation is optimised in South Africa for an orientation to the North and a slope of roughly 30°. For an elevated system, a certain distance between the rows is necessary to reduce shading effects. If the distance is reduced, the losses and the total installed power will increase and vice versa.

Does South Africa have enough irradiation?

Nevertheless, for all geographic regions of South Africa there is sufficient irradiation to enable a PV system to provide high yield – in summer and winter. Introduction
