Solar Finance in SA: Loan vs Rent-to-Own vs Subscription
By SolarGuide10 min read
Very few South Africans pay cash for solar, and there's no reason you should feel you have to. The whole appeal of financing solar is that it turns a big, off-putting upfront cost into a manageable monthly payment, often one that's close to, or below, the Eskom bill you're already paying. The catch is that there isn't one way to finance solar. There are several, and they work quite differently.
The three you'll run into most are a loan, a rent-to-own plan, and a subscription. Each answers three questions differently: who owns the system, what happens if your plans change, and what it costs over time. This guide lays them out plainly so you can match the finance method to your situation. No invented figures, just how each one actually works.
Key takeaways
The main routes are a loan (you own it, you owe the money), rent-to-own (own it at the end of a term), and subscription (you never own it, but you can cancel).
Ownership and flexibility pull in opposite directions — the more flexible the plan, the less likely you own the asset.
Rent-to-own is the popular middle ground: fixed monthly cost now, ownership later.
Subscription offers the lowest commitment and easiest exit, ideal if you're unsure or might move.
Whichever you choose, the key test is whether the monthly cost beats your rising Eskom bill.

Why finance solar at all
Start with the logic, because it reframes everything. When you finance solar, you're not really taking on a new expense. You're redirecting money you already spend. You pay Eskom every month regardless. Financing swaps some or all of that payment for a solar repayment that gives you backup power, a fixed cost, and in most cases eventual ownership of an asset.
Because Eskom's tariffs keep rising while a fixed repayment stays put, the deal tends to improve every year. That's the backdrop for all three finance options. The differences between them are about ownership, flexibility and long-run cost, not about whether financing makes sense in the first place.
Option 1: A solar loan
A loan is the most familiar route. You borrow the money, often as an extension of your home loan or a dedicated energy loan, buy the system outright, and repay the debt over time. From day one, the system is yours.
The upside: ownership and lowest long-run cost
Because you own the asset immediately, a loan usually delivers the lowest total cost over the long run. You're paying for the system plus interest, and nothing more. Once the loan's repaid, your power is effectively free for the rest of the system's life, which can be decades. If your priority is maximum long-term value and you can access affordable credit (a home-loan extension is often the cheapest), a loan is hard to beat.
The trade-offs
The flip side is commitment and qualification. You're taking on debt, it typically needs credit approval or available bond capacity, and the responsibility for the system, maintenance and insurance included, sits with you as the owner. It's the most grown-up option: best value, most commitment.
Option 2: Rent-to-own
Rent-to-own is the popular middle path, and it's the backbone of most of Alumo's packages. You pay a fixed monthly amount over a set term — commonly three years, with longer terms available — and at the end of it, the system is yours. It blends the affordability of a monthly plan with the eventual ownership of a purchase.
Why it's so popular
The appeal is obvious. There's little or no big upfront outlay, your monthly cost is fixed and predictable, and you walk away owning the system once the term ends. The Silver "Eishkom Ex" from around R2,035 a month and the Gold "Power Bae" from around R2,423 a month are classic rent-to-own deals: a fixed monthly figure that often lines up neatly against your current Eskom bill, with ownership waiting at the finish line.
There's also a longer-horizon version, a seven-year rent-to-own like the BrightStart plan from around R1,339 a month, which stretches the term to bring the monthly figure right down for households wanting the smallest possible payment while still ending up as owners.
The trade-offs
You're committed for the term, and it typically requires credit approval. Over the full period you'll generally pay somewhat more than a straight cash purchase, which is the cost of spreading it out and avoiding the upfront lump sum. For most households, that's a very acceptable trade for the cash-flow relief and eventual ownership.

A subscription flips the ownership question entirely. You pay a monthly fee for the use of a solar system — but you never own it, and crucially, you can cancel after a minimum period. Alumo's subscription starts from around R1,299 a month and can be cancelled after 24 months.
The upside: lowest commitment, easiest exit
This is the option for flexibility. It usually carries the lowest monthly figure and the smallest commitment, and because you can walk away after the minimum term, it suits anyone who's unsure, might relocate, or just doesn't want to own and maintain the hardware. Maintenance and warranty concerns sit with the provider, not you. It's the closest thing to solar as a service: power and load-shedding protection for a monthly fee, no long-term strings.
The trade-offs
You don't build ownership. Pay a subscription for years and you've bought a service, not an asset. There's no paid-off system at the end, no resale-value bump that belongs to you. Over a long enough horizon, a route that ends in ownership will usually work out better in pure rands. Subscription trades that long-run value for flexibility and the lowest barrier to entry.
There's no universal winner. It depends on what you value most. If you want the lowest long-term cost and immediate ownership and can access affordable credit, a loan wins. If you want a fixed, affordable monthly cost now and ownership later, rent-to-own is the sensible middle ground most people land on. And if you want maximum flexibility, the lowest entry point and the freedom to walk away, a subscription fits.
Run each against the one test that matters: does the monthly cost beat your current Eskom bill, given that Eskom's will keep rising and this won't? For most households, on all three routes, the answer is yes. So the real decision is about ownership and flexibility, not whether to finance at all. Want to see which plan fits your budget and home?

What are the main ways to finance solar in South Africa?
The three most common are a loan (you borrow, buy and own the system outright), rent-to-own (a fixed monthly payment over a term, after which you own it), and a subscription (a monthly fee for the use of a system you never own but can cancel). Cash purchase is a fourth option for those who can afford the lump sum.
Is rent-to-own or a subscription cheaper?
A subscription usually has the lower monthly figure and lets you cancel, but you never own the system. Rent-to-own costs a bit more per month but you own the asset at the end of the term. Over the long run, ending in ownership generally delivers better total value; a subscription buys flexibility instead.
Which solar finance option lets me own the system?
Both a loan and rent-to-own end in ownership — a loan immediately (you own it while repaying the debt) and rent-to-own at the end of the term. A subscription does not; you pay for the use of the system without owning it.
Do I need to qualify or be credit-approved for solar finance?
Generally yes — loans, rent-to-own and subscription plans typically involve credit approval, and a home-loan extension depends on available bond capacity. The exact requirements vary by product and provider.
How do I choose the right solar finance option?
Match it to what you value: lowest long-term cost and ownership (loan), affordable monthly cost plus eventual ownership (rent-to-own), or maximum flexibility with an easy exit (subscription). Then check the monthly cost against your rising Eskom bill. SolarGuide is an independent referral partner — Alumo supplies, installs, finances and warrants the systems.
