South Africa has the largest carbon footprint in Africa and contributes 40% of the total CO2 emissions in the continent. As the world evolves in response to climate change concerns, the way business is done in South Africa will need to change.

In addition to the critical need for every business to contribute to broadly reducing the carbon footprint, the introduction of a number of policies, incentives, and changes in the business environment are resulting in a rapidly strengthening economic case for renewable energy. With factors such as the Renewable Energy Independent Power Project Procurement Program (REIPPPP), tax incentives for businesses, decreasing costs of solar system components, increasing tariffs charged by Eskom (the largest utility in South Africa), load shedding, and finance options now available, the positive impact to a company’s bottom line is impossible to ignore.

Aside from the well-known cost implications of load shedding for most businesses, this article reviews a few key considerations when thinking about installing a solar power system for your business.

SSEG and Net Metering

Small-scale embedded generation (SSEG) has been piloted in the Western Cape for a number of years, and other provinces are beginning to follow suit. SSEG refers to renewable power generation under 1 MW, located on residential, commercial, or industrial sites.

Most of the power generated by an SSEG user is consumed on site, but there may be times when generation exceeds consumption, and typically a limited amount of power is allowed to flow onto the municipal electrical grid. One of the major advantages of such a system is that it can help reduce or eliminate the need for backup batteries that off-grid or grid-tied systems often include.

Under a net-metered system, when the solar system generates more power than your business consumes, the excess power goes back into the grid and you receive a credit at a fixed rate. All indications are that the South African government will begin to facilitate SSEG through more active implementation of the existing policy, and more progressive policy changes in the years to come.

Electricity tariffs have increased by 300% in South Africa over the last 10 years. Given the current debt trap caused by new power plants such as Medupi and Kusile, this rapid rate of increase is set to continue into the foreseeable future. According to University of Cape Town’s Energy Research Centre, South Africa has reached a point where electricity generated from new wind and solar power plants is currently 200% cheaper than electricity generated by Medupi and Kusile.


There are a number of financing options available to a business wanting to install solar. These include straight financing of the system via a loan, power purchase agreements (PPAs), and rental agreements. The long-term rental option is the most feasible for the majority of businesses. There are a number of key advantages to renting including:

  • Less Cash Needed. Long-term rental requires no deposit
  • Production Value. International case studies have proven that the use of equipment is far more important to the production of income than owning that equipment.
  • Off Balance Sheet Financing. Rentals are a non-balance-sheet item, and therefore do not affect the financial gearing of the company. They have no effect on the return on assets managed, and actually have a positive effect on the return on assets owned.
  • Inflation Hedge. When compared to conventional forms of financing, rental agreements, with their flexible structures, offer a hedge against inflation. Payment is not linked to uncontrollable financial factors and instead is linked to pre-agreed terms and conditions with no deposit requirements.
  • Tax Advantages. Value-added tax (VAT) is payable on monthly rentals as they fall due. In other forms of financing, VAT is payable on the capital value of the equipment all at once.
  • Diversification of Financing Sources. Large companies obviously require financing for a wide spectrum of assets and projects. Vehicles and buildings are but a few. Rental facilities offer the end-user a new source of finance due to their off-balance-sheet nature. In addition, renting provides breathing room to acquire other financing as needed.
  • Conservation of Working Capital. As no deposits or initial lump-sum payments are required, rental offers a low entry-level cost, reducing the use of working capital.
  • After-Taxation Present Value of Cost. In terms of total after-tax present value of costs, renting may be cheaper than conventional financing. However, it is important to note that this situation only occurs when the renter is in a tax-paying situation
  • Flexibility. Payment structures and terms are only limited by the economic lifespan of the equipment and the end-user’s budgetary constraints.
  • Maintenance. As ownership of the equipment is not vested in the user, the owner is responsible for ensuring equipment is in operational order at all times, shouldering the costs and time commitments to do so.

Tax Incentives for Solar Energy

Should a business still feel that they would prefer to purchase a solar system outright, there are some tax incentives available. Not many businesses in South Africa are aware that as of Jan. 1, 2016, an amendment to Section 12B of the Income Tax Act (Act 58 of 1962) provides for depreciation in the year of commissioning of the full (100%) cost of a grid-tied solar PV system of less than 1 MW used for electricity generation by a business in the course of its operations.

The capital depreciation allowances for solar PV systems greater than 1 MW did not change, but the legislation continues to allow full depreciation over three years—50% of the capital cost in the year of commissioning, 30% in the subsequent year, and 20% in the third year. This depreciation allowance for solar PV systems applies regardless of who installs the system for a business, whether by contractors or developers, or paid for by the business in a credit sale agreement (as defined in Section 1 of the Value-Added Tax Act)—either upfront in a single payment or in multiple payments over an extended period.

As confirmed by a binding private ruling (BPR 311) by the South African Revenue Service (SARS) dated Oct. 11, 2018, the cost of the solar PV system allowed for accelerated depreciation includes its full direct capital cost: design and engineering, project planning, delivery, foundations and supporting structures, solar PV panels, AC inverters, DC combiner boxes, racking, cables and wiring, and installation. Finance costs are excluded.

It is easy to see that government policies and tax law have turned the tide in favor of renewable energy for South African business owners. Installing a solar power system to run a company can pay for itself over the course of its life. With credits granted for excess power production, a spike in tariffs for standard electricity, an increase in access to financing options, and tax incentives for solar power system owners, the economic case for clean energy in this country has never been stronger.
