African photovoltaic panel specifications

What is a photovoltaic (PV) panel?

Photovoltaic (PV) panels are the core of any solar power system. Understanding key specifications will help you compare quality, performance, and long-term reliability across different brands and technologies. This guide explains the most important technical terms so you can make an informed solar investment.

What are the solar PV installation guidelines?

It should be noted that Solar PV installers are advised to use the Solar PV Installation Guidelines in conjunction with all relevant national electrical codes, building codes and regulations. Furthermore, metering and exporting of solar-generated electricity must be done in compliance with the actual legal requirements. Introduction

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.

Where can I find a comprehensive overview of photovoltaic systems?

In order to gain a more comprehensive overview of all kinds of PV installations, we recommend to study the DGS Manual Planning and Installing Photovoltaic Systems – A Guide for Installers, Architects and Engineers(as published by the German Solar Energy Society, DGS).

Is SseG possible through rooftop solar PV?

The potential for SSEG through Rooftop Solar PV is extremely important when aligned with the Government objective to provide access to a reliable, affordable and environmentally friendly energy supply. South Africa’s PV market is quickly growing with more than 300 MWp of rooftop systems installed at the end of 2016.

What irradiation value should a PV module have?

On most data sheets for PV modules the values given are at STC and NOCT. Some manufacturers also provide the efficiencyreduction for an irradiation of 200 W/m² as a percentage value. The information on the data sheet (below) is required for sizing a PV system. Always read the correct value.
