Solar price comparison: Rental vs. financing vs. rent-to-own

As load-shedding plagues South Africans, acquiring a backup power system is crucial, yet daunting. With the cost of solar panels, inverters, and batteries decreasing, options to fund these systems monthly emerge. Choose rental services for flexibility but face potential cancellation fees. Major banks offer loans specifically for alternative energy financing, allowing payments over six years. Opt for rent-to-own for ownership with full maintenance, albeit at a higher cost. Alumo Energy, among others, provides various configurations. Make an informed decision with our detailed comparison of pricing and terms.

South Africans seeking a backup power system to shield them from load-shedding can fund their purchase in one of three ways if they don’t have the cash to buy it outright.

The prices of solar panels, inverters, and batteries have decreased substantially in the past few months.

However, it will still cost the average South African household tens of thousands of rand to buy a system capable of providing sufficient backup power during load-shedding for their essential appliances.

Most people don’t have that type of money lying around, particularly when high inflation has forced many households to tighten their budgets.

Fortunately, there are ways to pay a monthly fee for such a system to make it more affordable.

Below, we have explained the three main ways to get a backup power system by paying for it monthly.

Rental or subscription service

The first option to consider is a rental or subscription service, which gives you the benefit of a backup power system without the responsibility of owning and maintaining it.

This is the best choice for those who don’t necessarily want to sign up for a long-term financial commitment or those who cannot get approval for a loan.

The effective cost of the system will also be lower than the actual premium because you can reduce your grid-consumed electricity bill substantially if you choose to include solar panels in your plan.

However, despite this being the most flexible option, there are some significant drawbacks to consider.

Firstly, all the money you spend will be purely for relief from power cuts and a potential reduction in your electricity bill.

There is no long-term benefit where the system will eventually have paid for itself through electricity savings.

Secondly, cancelling a rental plan can come with a substantial cancellation fee.

One popular provider — Goslr — charges de-installation fees starting at R22,770.

Its packages operate on an evergreen contract, so there appears to be no time at which this cancellation fee no longer applies.

The table below compares Goslr and Hohm Energy’s Glint solar subscription services.

Standalone or home loan-linked financing

Responding to the intensified power cuts over the past few years, all of South Africa’s major banks now offer personal loans specifically for alternative energy financing, similar to vehicle finance.

This allows you to pay the system off in monthly premiums over up to six years (72 months), depending on the bank, at an interest rate that matches your credit profile.

You can buy your system from one of numerous accredited solar installers in South Africa and pay for it with financing.

This includes companies like Alumo Energy, AWPower, Hohm Energy, LookSee, and Solar Advice.

The typical approach to apply for a loan would be to submit a quote from your chosen installer for approval.

The bank will then pay the installer the full price of the system, which you will repay to the bank.

Those with a home loan can add a financed solar system to their existing bond at an additional monthly cost. The combined financing of the home and system will be treated as a single loan.

The advantage of this option is that you can get the best possible interest rate for your profile and pay the equipment off over the number of years left on your home loan.

The downside to financing is that you are at the mercy of warranties or insurance when it comes to repairs or replacements. You must take out appropriate insurance and keep your premiums up-to-date to avoid disaster should something go wrong.


For those who want to end up owning the system but also need the peace of mind of full maintenance and technical support, rent-to-own is the way to go.

With this approach, you will generally pay more than when renting or financing a system of the same size, but you may get benefits like insurance, regular maintenance, repairs, and replacements in the event of damage that did not occur by your hand.

Alumo Energy is among the well-known companies that offer this model.

It has a range of preconfigured systems for grid-tied and off-grid backup systems with capacities to suit households with widely varying electricity consumption habits.

Alumo Energy offers contracts over three, five, and seven years, after which you can either choose to have the system removed or pay a fixed fee to become its owner. The buy-out amounts for each system are shown on its website.

For an entry-level system with 3.6kW output, 3.6kWh backup, and no solar panels, this can be as low as R5,100 after a 7-year contract is over.

The same system’s buy-out will increase to over R20,000 over the shortest 3-year term.
