Solar Market Outlook in South Africa

South Africa is striving to reduce its reliance on the state-owned utility for electric generation. Therefore, it is exploring sustainable solutions and renewable energy sources like solar provides the most viable answer. In addition, the current electric utility is unable to meet the power demand due to operational and financial issues. 

The South African government recently considered solar and renewables to address power shortage. The South Africa Photovoltaic Industry Association reported that the new PV systems installed in the country generated a total capacity of 1,313 MW. Of the new installations, about 813 MW of them were dedicated for utility scale and the remaining 500 MW were from distributed generation arrays. By the end of December 2020, the total solar capacity in South Africa reached 4,172 MW. The residential installations contributed to 20% of the country’s current solar capacity. 

The continued expansion of solar capacity in the commercial and industrial scale has prompted the government to continually evaluate its policies. It is also integrated into the government’s post-covid economic recovery plans.

Wholesale Disconnects for Solar Systems

Essentially, safety disconnects allow users to rapidly shut down the system in case of an emergency. For this reason, disconnect switches are required to comply with electrical codes and pass inspection. 

A solar PV system usually has two safety disconnects. The first is the PV disconnect (or array DC disconnect). This kind of disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. 

The second disconnect is the AC disconnect. The AC disconnect is used to separate the inverter from the electrical grid. In a solar system, the AC disconnect is typically mounted to the wall between the inverter and utility meter. This kind of disconnect may be a breaker on a service panel, or it may be a standalone switch. Additionally, it is sized based on the output current of the inverter. 

How to Size an AC or DC Disconnect?

Generally speaking, sizing refers to equipment, components, and connectivity (wiring) throughout a solar system as it relates to NEC requirements. The following terms are used to determine component output: 

  • Voltage
  • Circuit load
  • Amps or breaker size
  • Wiring or cables
  • Sizing and Protection of the AC Disconnect

NEC 690.10 stipulates that the circuit conductors between the inverter output and the building or structure disconnecting means shall be sized based on the output rating of the inverter. These conductors shall be protected from overcurrents in accordance with Article 240. The overcurrent protection shall be located at the output of the inverter. 

Important Features to Look For in Disconnect in Bulk?

Disconnects are incredibly useful for solar systems, and so, it is important to get the best possible disconnect for your own solar system. The following are the core features to look for in a disconnect: 

  • Offers bi-directional functionality, which breaks the arc regardless of normal or a reverse current flow
  • Includes all required components to meet NEC 690 requirements, including jumpers and labels
  • Guards against accidental contact with live parts with clear polycarbonate dead fronts
  • Available with modifications that allow customization to meet any application need
  • Sizing of Module Interconnection Conductors and DC Overcurrent Protection

According to NEC 690.80, where a single overcurrent device is used to protect a set of two or more parallel-connected module circuits, the ampacity of each of the module interconnection conductors shall not be less than the sum of the rating of the single fuse plus 125% of the short-circuit current from the other parallel-connected modules.

Distributors

Solar Products Distributors

Distributors are those companies working as big warehouses that served as the middlemen between the consumer/customer and the manufacturer. Typically, in distribution, a company is handling the sourcing, stocking and logistics but nowadays they are also helping manufacturers in product designing and solving other business conflicts. 

Aside from other industries, distributors also play a vital role in the solar industry. Solar distributors become long-term partners of solar manufacturing companies and even solar contractors. They are not only serving as warehouse facilities but partners that also provide strategic solutions to help solar companies achieve their desired outcomes. Solar distributors assist solar manufacturing companies by storing. handling and shipping their solar products to their buyers. On the other hand, they help solar contractor companies in outsourcing high-quality solar products. 

These solar distributors are the ones who deal with homeowners who want to go solar, businesses that work with the solar industry and solar installers who offer solar system services to both residential and commercial customers. But on top of that, the solar distributor’s main role is to maintain its commitment to outsourcing and handling high-quality products and delivering them to customers at a good value. 

Up to these days, many solar distributors have been operating and helping many solar companies in distributing their products. So, if you are looking for the most trusted and reliable solar distributor, you can easily find one by checking out solar outsourcing companies that provide easy access to reliable information, news, data and a list of solar suppliers and distributors near you.
