Solar Subscription Explained: Pay Monthly, No Deposit
By SolarGuide8 min read
For years the barrier to going solar was the same brutal number: a cash outlay big enough to make most households flinch. You wanted out of load-shedding and off the tariff treadmill, but not badly enough to hand over a hundred thousand rand upfront. The solar subscription exists to remove exactly that barrier.
Instead of buying a system, you pay a fixed monthly fee to use one. There is no deposit, the hardware and its upkeep stay someone else's problem, and you can walk away after a set minimum period. It sounds almost too easy, so let us unpack how it actually works, who it suits, and where the trade-offs sit.
Key takeaways
A solar subscription lets you use a fully installed system for a flat monthly fee with no deposit and no ownership.
Alumo's subscription starts from around R1,299/month and you can cancel after 24 months.
Maintenance, monitoring and equipment risk sit with the provider, not you, which removes the biggest ownership headache.
You will not build an asset the way rent-to-own does, so subscriptions suit flexibility over long-term ownership.

What a solar subscription actually is
A subscription is a usage model. The provider installs a solar and battery system at your home at no upfront cost, retains responsibility for the equipment, and charges you a predictable monthly amount to use it. Think of it the way you already think about your fibre line or your DStv package: you pay for the service and the outcome, not the box on the wall.
The system still does everything a purchased one does. Panels feed your home during the day, the battery carries you through load-shedding and into the evening, and the inverter manages the flow between solar, battery and the grid. The difference is purely financial and contractual.
The headline numbers
Alumo's subscription option, sometimes badged as the Hot Deal, uses an AlphaESS 5kW inverter, a 3.6kWh battery and four panels, from around R1,299/month. Crucially, there is no deposit, and you can cancel after a 24-month minimum term. That combination — low entry, no capital, genuine exit — is what sets a subscription apart from finance.
How it differs from rent-to-own and buying outright
This is where most people get confused, so it is worth being precise. There are three distinct routes, and they solve different problems.
Buying outright
You pay the full cost, roughly R47,000 and up depending on system size, and you own everything from day one. You capture the maximum long-term saving because there is no financing cost, but you also carry all the risk and the full upfront hit.
Rent-to-own
You pay a fixed monthly amount over a term — Alumo offers 3-year and 7-year structures from around R1,911/month and R1,339/month respectively — and at the end the system is yours. It is the middle path: no big deposit, but you are building towards ownership of an asset.
Subscription
You never own the hardware. You pay for use, the provider handles everything, and you can leave. It is the most flexible and the lowest-commitment, at the cost of not building equity in the equipment.

Subscriptions shine for specific situations rather than everyone.
If you rent your home, or you are not certain you will stay put for the next decade, a subscription lets you enjoy solar without sinking capital into a property you may leave. If you simply do not want to think about firmware updates, battery health or the odd fault, handing that risk to the provider is worth a lot. And if your priority is escaping load-shedding this year without a credit-heavy purchase, the no-deposit entry gets you there fast.
It also suits the cautious. Committing to owning a system for 15 years is a big call. A 24-month minimum with a clean exit lets you prove the savings to yourself before you decide whether to pursue ownership later.
Where it is the wrong fit
If your goal is the lowest possible lifetime cost and you plan to stay in your home for many years, buying or renting-to-own will almost always beat a subscription over time, because you eventually stop paying and own an asset that keeps saving you money. A subscription, by design, is an ongoing fee for as long as you use it.
The practical details worth checking
Before you sign anything, get clear on a few points. Confirm what the monthly fee includes — a good subscription bundles monitoring, maintenance and repairs, so you are never billed for a failed component. Check the cancellation terms beyond the minimum period, including what happens to the equipment when you leave and whether removal is handled for you. And make sure the system is sized to your actual consumption rather than a generic default, because an undersized subscription that still leaves you buying heavily from Eskom defeats the purpose.
All of this comes out of a proper site assessment, where the provider looks at your roof, your usage and your load-shedding exposure. Get a free quote → to get numbers matched to your home rather than a generic estimate.
Is a subscription the right call for you?
Run it against a simple test. If flexibility, zero maintenance worry and no upfront cash matter more to you than eventually owning the hardware, a subscription is a strong fit. If squeezing out the lowest lifetime cost matters most and you are staying put, lean towards rent-to-own or an outright purchase.
There is no universally correct answer — only the one that matches your plans, your cash flow and your appetite for commitment. The good news is that all of these routes get you the same practical result: lights and appliances that stay on when the grid does not, and a smaller Eskom bill every month.

Frequently asked questions
Do I own the solar system on a subscription?
No. With a subscription you pay a monthly fee to use a system that the provider owns and maintains. This is the key difference from rent-to-own, where you are working towards owning the equipment at the end of the term.
Is there really no deposit?
Correct. Alumo's subscription requires no deposit, which is one of its main attractions. Your first commitment is the monthly fee, and the arrangement is subject to a site assessment and credit approval.
What happens if I want to cancel?
Alumo's subscription allows cancellation after a 24-month minimum term. Always confirm the exact cancellation process and what happens to the installed equipment when you leave, as this is handled by the provider under the agreement.
Who fixes the system if something breaks?
On a subscription, the provider carries responsibility for the equipment, including monitoring, maintenance and repairs of covered components. That transfer of risk is one of the biggest practical advantages over owning outright.
Is a subscription cheaper than buying over the long run?
Usually not, if you stay in your home for many years. A subscription is an ongoing fee for as long as you use the system, whereas buying or renting-to-own eventually ends and you own an asset.
