Why financing solar has become normal in South Africa
A decade ago, solar was something you paid for in full or not at all. That has changed completely. With Eskom tariffs climbing well above inflation year after year, and load-shedding making backup power a near-necessity, installers and banks have built a whole range of finance products around solar.
The result is that you no longer need R50,000 in the bank to start. You can move to solar for a fixed monthly amount that often lands close to — or below — your current electricity spend. That's the real shift: solar has gone from a luxury purchase to a monthly utility you can own.
Option 1: Buying solar outright
Buying outright means you pay the full system cost up front and own everything from day one.
The upside
- Lowest total cost. You pay no interest or finance charges, so over the life of the system this is always the cheapest route.
- Immediate savings. From the day it switches on, the money you'd have paid Eskom stays in your pocket.
- It's your asset. A paid-off solar and battery system adds appeal and resale value to your property.
The trade-off
You need the cash. A typical Alumo home system runs from around R44,980 to R51,357 outright, depending on size. If that lump sum would drain your emergency fund or come off a high-interest debt like a credit card or bond, financing may actually leave you better off month to month.
Outright purchase suits homeowners who have the savings available, plan to stay put for years, and want the maximum long-term return.
Option 2: Rent-to-own
Rent-to-own is the middle path, and it's the most popular choice for good reason. You pay a fixed monthly amount over a set term — commonly 3 or 7 years — and at the end of the term the system is yours.
With Alumo, the entry-level Bronze package pairs a 3.6kW Sunsynk inverter with a 3.8kWh battery and four panels from R1,911/month on a 3-year rent-to-own. The Gold package — a 5kW inverter, 5.32kWh battery and six panels — comes in around R2,423/month. Longer 7-year terms (like Alumo's BrightStart) push the monthly figure down further, from around R1,339/month, in exchange for paying over more years.
Why people choose it
- No large deposit — you keep your savings intact.
- Predictable monthly cost you can budget around.
- You end up owning the system, unlike a pure rental.
- The monthly amount is often similar to your current electricity bill, so you're redirecting money you already spend into an asset.
The trade-off
Because you're paying over time, the total cost is higher than buying cash. You're paying for the convenience of not needing a lump sum — the same trade-off you make with any vehicle or home finance.

Option 3: Monthly subscription
A subscription is the most flexible and lowest-entry option. You pay a monthly fee for the use of the system, and Alumo's Hot Deal subscription starts from R1,299/month for an AlphaESS 5kW inverter with a 3.6kWh battery and four panels — with the option to cancel after 24 months.
Why it appeals
- Lowest monthly entry of all the options.
- Maximum flexibility — useful if you're not certain about your long-term plans.
- No large commitment locked in for years.
The trade-off
You don't own the system while you subscribe, so you're not building towards an asset in the same way as rent-to-own. It's best thought of as a way to slash your bill and get backup power now, with room to change your mind later.
How to choose: a simple decision guide
Ask yourself three questions:
1. Do I have the cash — and is it "spare" cash?
If you can pay outright without touching your emergency fund or taking on debt, buying is usually the best long-term value. If not, financing is the sensible route.
2. How long will I stay in this home?
Planning to stay five years or more? Rent-to-own or buying both make strong sense, because you'll enjoy years of ownership and savings. Less certain about your plans? A subscription's flexibility may suit you better.
3. What matters more — lowest total cost, or lowest monthly cost?
- Lowest total cost → buy outright.
- Lowest monthly cost with eventual ownership → rent-to-own (a longer term lowers the monthly figure).
- Lowest monthly cost with maximum flexibility → subscription.

Frequently asked questions
Is rent-to-own more expensive than buying cash?
Over the full term, yes — you pay for the convenience of not needing a lump sum, similar to financing a car. But if paying cash would mean draining savings or taking on high-interest debt, rent-to-own can leave you better off overall.
Do I own the system with rent-to-own?
Yes. At the end of the rent-to-own term, the system becomes yours. With a subscription, you don't own it while you subscribe — that's the main difference between the two.
What happens if I sell my house?
This depends on the finance agreement and where you are in the term. Alumo can explain your options, including settlement or transfer. It's worth raising during your quote if a move is on the cards.
Can the monthly amount really be close to my current bill?
Often, yes. Because Eskom tariffs are high and still rising, many households find the rental lands near what they already pay for electricity — the difference being that you're paying towards a system you'll own rather than a bill that only goes up.
How do I find out the exact price for my home?
