You can build your independence in stages if you dream of cutting ties with the grid.

The term ‘load-shedding’ was first used in late 2007, since then South Africans have been dealing with regular power interruptions on the national grid for 14 years. There is no way of knowing how long this situation will continue, or when we will be able to rely on the grid 24/7 again. Many of us have bought diesel generators to power the essentials in our homes during outages, but that solution is noisy and expensive, while contributing to air pollution and greenhouse gas emissions.

Solar power is cheaper than ever before, practical, and available

The simplest solution is a battery and inverter system, which will supply your essential electricity needs over a few hours to cover load-shedding, after which it needs to be recharged. But if you recharge it using grid power, you’re paying the same price for grid electricity, and then adding extra expense to store it up and use it when the grid fails to deliver.

That’s why it’s worth investing in photovoltaic solar panels that turn sunlight into electricity – whether you just want to recharge a battery and inverter system that provides power during load-shedding, or if you’re even considering going off the grid completely.

Rapid advances in technology have driven down the cost of installing a solar energy system, making this far more affordable than you might think – and there are several financing options available.

Depending on your budget, it might make sense to start by installing a system just to cover your basic power needs during load-shedding.

 Solar and battery backup solutions are not cheap investments, so it’s important that all systems are correctly designed and sized to ensure that enough power and runtime are available to cover your needs, as well as to ensure optimal return on investment from your solar system. Work with a reputable solar contractor accredited by the South African Photovoltaic Industry Association (SAPVIA – the representative body of the solar PV industry in South Africa), to establish the right balance between solution sizing and your budget.

If load-shedding should continue or get worse over the next 10 or 15 years, you’ll still be spared the inconvenience, stress and lost productivity caused by power failures. It’s always best to seek expert advice on exactly what your home would need to become energy self-sufficient, so it’s important to find installers accredited by SAPVIA and who use only quality products.

Start with a load-shedding solution

Depending on your budget, it might make sense to start by installing a system just to cover your basic power needs during load-shedding. By adding solar panels and batteries to the system later, you can scale up to a full solar conversion.

As a rough estimate, a backup solution that will provide 2 to 4 hours of power will cost around R70 000 for low-use households, R95 000 for medium-use households and up to R120 000 for high-use households, including installation and a certification of compliance. A battery backup will wire into your DB board and provide a seamless transition to backup power when the grid goes down.

Generally, the battery backup should have sufficient capacity to power your lights, fridge, freezer and essential plugs, but will exclude heating appliances like ovens and toasters. But remember, the costs mentioned are for a battery backup that recharges from the grid, not a solar panel.

Building energy independence, step by step

Going completely off the grid requires a solar system capable of producing enough electricity to power your peak consumption, coupled with a battery backup that can power your house during hours where there is no sunlight.

On average, for a low-consumption household this will cost around R150 000, for a medium-sized household about R250 000 and for a large household at least R350 000. On a 10-year loan at 10.75% interest, that translates to monthly payments of R 2 045,08, R3 408.25 and R4 771.85 respectively.

This journey to energy independence doesn’t need to be tackled all at once. You will be able to scale your system as your needs grow. Discuss these options, and the stages in which to add them, when planning the conversion with your solar contractor.

Are the savings worth the cost?

Based on the figures in our examples, switching to solar could save you at least R1 700 on your monthly electricity bill from the start. Your loan repayments are likely to be slightly higher than that, so in the beginning you will be paying more for your electricity – in return for the convenience and security of uninterrupted power whenever you need it.

Once your system is paid off, though, the electricity it provides is free. That will add up to a massive saving over the years. Depending on how much power you use, doing a full off-the-grid conversion could take between 11 and 14 years before the money you’ve saved equals the cost of the system; the point at which it has paid for itself.

Using your home loan to finance a solar conversion won’t yield savings overnight, but it will in the long run.

Using your home loan to finance your solar conversion

The most affordable way to pay for your solar installation is to use your home loan, because home loans offer lower interest rates than personal loans. Financing the installation this way could add between R700 and R2 000 to your monthly loan payments, depending on the size of the system you need. Remember, though, that the increase in your home loan instalment will be offset by a decrease in your electricity bill – so the switch may not affect your monthly budget that much.

Using your home loan to finance a solar conversion won’t yield savings overnight, but it will in the long run – once it’s paid for, you’ll have permanent free electricity. Other perks are an uninterrupted power supply and reducing your household’s impact on the environment – both issues that matter just as much as cutting costs.

While it is difficult to qualify the actual value-add in monetary terms, having off the grid installations make a property more sellable.

“If there are two equivalent homes on the market and one has green features, the green home will appeal to a wider market and will sell quicker than the home without such features.” Says Shaun Rademeyer, CEO MultiNET Home Loans

An added benefit says Rademeyer “For private households, individuals who install rooftop solar panels from 1 March 2023 will be able to claim a rebate of 25% of the cost of the panels, up to a maximum of R15,000.”

“This can be used to reduce their tax liability in the 2023/24 tax year. This incentive will be available for one year,”

To qualify, the solar panels must be purchased and installed at a private residence, and a certificate of compliance for the installation must be issued from 1 March 2023 to 29 February 2024.
