Alumo Energy Review (2026): Is Rent-to-Own Solar Worth It?

You've probably seen Alumo's adverts, or passed one of their branded vehicles in your neighbourhood, the ones that say "On our way to turn you on", or there's an Alumo quote waiting for your answer. Before you sign for seven years, you want to know two things. Is the company solid, and what does rent-to-own really cost by the end?

Alumo shows the buy-out and the cash price for every system it rents, so the second question has a real answer. In this review I've added up each term in rands, gone through what happens if you sell or rent out your home, and looked at how its customers rate it.

Who Alumo Energy is, and what it sells

Alumo Energy is a South African solar company that has been installing since 2017. Its head office is in Pretoria, with offices in Vanderbijlpark and Middelburg, and it sells solar and battery systems to homes and businesses.

What it really sells is ownership on a monthly payment. You pay nothing upfront, Alumo installs and insures the system, services it once a year, and at the end of the term you buy it for a small final amount. If you'd rather never own it, there's a subscription you can cancel after 24 months, and you can also buy a system in full.

Alumo doesn't outsource its installations. Its own teams fit every system, and it guarantees their workmanship for three years, on top of 10-year warranties on the home equipment. The home plans run on Solis inverters and Eenovance batteries, and Alumo also installs Sunsynk and AlphaESS systems.

What Alumo takes off your hands, and who it suits

Going solar on your own means choosing an installer and the equipment, finding R70 000 or more, insuring the system and arranging its servicing. Alumo turns all of that into one monthly payment, and the system becomes yours at the end of the term.

That suits a household that wants solar now without a loan or its savings, and likes having one company to call.

It suits you less if you can pay for a system in one go, because paying in full costs far less over the years. Then my ranking of nine solar companies compares kits you pay for once, though Alumo's shorter terms below are still worth a look.

My verdict on Alumo Energy

My verdict is that Alumo does what it promises. It gets you solar with no cash upfront and hands you the system at the end, and its customers rate it highly. What you give up is cost over time, which the next sections put in rands.

What's in the fee is Alumo's strongest point. Insurance, a yearly service and a swap-out warranty on the inverter and battery are the costs that catch people who buy a system and then pay for every callout themselves.

Its weak point is the total over the term, and that's the one thing to understand before you sign. Rent-to-own is a way of paying, so the shorter the term, the less you pay in total.

Alumo's home plans, from 3 panels up

Alumo's home plans start at R1 449 a month for a 5 kW Solis inverter, a 5.32 kWh battery and three panels, rented over seven years. The bigger your electricity bill, the bigger the system it quotes, up to 24 panels and two inverters at R4 349 a month. The box below has every size, and right now there's no initiation fee if you accept your quote within seven days.

Which Alumo plan to ask for

• If your bill is under R1 500 Start on the 3-panel system at R1 449 a month over seven years. It mainly carries you through power cuts, so expect a smaller bill, not a tiny one.
• If your bill is R2 500 or more Ask Alumo to price 10 panels and two batteries, from R2 399 a month. Alumo estimates that size saves you R1 991 a month.
• If you can pay more each month Ask for the three-year term. On the 3-panel system it's R2 049 a month, and about R48 000 less in total than seven years.

The entry system is small. Three panels keep the battery topped up for the evening and carry about three hours of backup, but they won't run much of your daytime use. Alumo's own calculator estimates it saves R634 a month, which is less than the rental, so at this size you're paying mainly for power through load-shedding and a system you'll own.

The savings get closer to the rental as the system grows. On 10 panels with two batteries at R2 399 a month, Alumo estimates R1 991 a month off your bill, and the rental only rises 6.5% a year. Eskom's tariffs went up 8.76% from April this year, so if your electricity keeps rising faster than your rental, the gap closes every year.

If you'd rather never own the system, Alumo's subscription starts at R1 499 a month for seven panels, a 5 kW inverter and a 5.32 kWh battery. That's more than twice the panels of the entry rent-to-own system for R50 more a month, with a once-off fee of one month's subscription. You can cancel after 24 months, and extra panels are R99 a month each.

So the choice comes down to the end of the term. Rent-to-own leaves you owning panels that Alumo expects to keep producing for 25 to 35 years, while the subscription keeps you paying for as long as you use it.

What rent-to-own costs over the whole term

Over seven years, the 3-panel system costs about R155 300 in rent and the final buy-out, against R70 691 to buy it in full. The term you pick decides most of that, so I've added up all three for the same system. The monthly rental goes up 6.5% every year, and the table counts that.

So what does the extra buy you? Seven years of insurance against damage and theft, a yearly service, an inverter and battery that Alumo swaps out under warranty, and not having R70 691 leave your account on day one. If you'd be borrowing that money anyway, a personal loan carries interest too, and it covers none of those.

You also don't have to stay for the full term. Alumo lets you buy the system out at any time, so if a bonus or a tax refund lands in year three, you can settle early and stop the escalation there.

One cost isn't in any quote estimate. Alumo's prices exclude SSEG registrationSSEG (small-scale embedded generation)A generating or storage system connected to wiring that the municipal grid also supplies, which the municipality has to approve. It is decided by the wiring, not the technology: an inverter and battery with no solar panels is an SSEG once it is wired into the distribution board, and a unit that only charges from a wall socket is not, because it counts as an appliance. Each municipality sets its own rules and fees, so the requirements are local rather than national. Checked against a municipal SSEG FAQ on 10 September 2026.With AlumoAlumo says approval can take 6 to 12 months, depending on your municipality, and its quote estimates exclude the registration. So when the quote arrives, look for who files the application and what it costs., the municipal approval a grid-tied system needs, and its quote assumes 7 m of cabling and space for two breakers in your DB board.

If you sell, rent or move

If you sell your home, the buyer can take over your Alumo agreement, or you can buy the system out or apply to cancel early. Alumo spells out how each of these works, which matters on a contract that can outlast your time in the house.

First, a transfer is done only once your buyer has passed Alumo's credit check, signed a new rental agreement and Alumo has it back. Registering the house in their name doesn't move the agreement, and neither does a clause in the offer to purchase, so you keep paying until Alumo has that signature. Raise it with Alumo as soon as the house goes on the market.

Second, if the buyer doesn't want the system, you buy it out at the amount Alumo calculates or apply for an early cancellation. A new owner can also ask Alumo to move the system, after an assessment and at a cost.

Last, renting your home doesn't rule you out. Your landlord can co-sign the agreement, which gives Alumo access to the property without making the landlord liable for the payments.

Alumo for businesses, farms and lodges

Alumo rents business systems the same way, over seven years with a buy-out, starting at R18 000 a month for 120 kWh of batteries and a 50.05 kWp array. That system costs from R999 000 to buy, and Alumo estimates it saves R16 216 a month. Its larger tier starts at R34 000 a month, and anything bigger is designed for your site.

The business side also covers energy audits, maintenance under a service agreement, and panel washes four to ten times a year. Alumo will maintain a system it didn't install, which helps if your first installer has gone quiet.

Its lodge work shows what that looks like. At Tshikwalo Game Lodge, Alumo built a hybrid and off-grid system with 432 kWh of batteries because the council supply was limited, and the lodge's monthly spend fell from R74 850 to R31 350. At Shammah Lodge, a 50 kW system went in within two weeks, and monthly spend dropped from R29 857 to R12 503.

Alumo's other case studies include Romans Pizza's headquarters and main distribution centre and the Boundless Soweto Campus, where it says the school's monthly electricity cost was eliminated. If your business runs a cold room, a kitchen or pumps through the day, those are the closest examples to yours.

Can you count on Alumo for seven years?

From what I can see, yes. A seven-year contract is only as good as the company still answering the phone in year five, and Alumo's track record points the right way. It's been installing since 2017, it has three offices, and the people who fit your system work for Alumo.

Aftersales support runs by phone 24 hours a day, every day of the year, on 087 133 0033, and Alumo keeps DIY videos for small faults you can fix yourself. The three-year workmanship guarantee is signed off by its directors.

Its customers back that up. On Hellopeter, Alumo averages 4.7 out of 5 from 75 reviews, 88% of them five stars, and it had replied to every negative review when I looked on 30 October 2026. Reviewers often name their installers, and several say the team explained the system before leaving.

The complaints that do come up are about after-sales calls going unanswered and a few battery faults. Both are covered by what you're paying for, so if it happens to you, the warranty and the maintenance in your fee are what you call on, and the 24-hour line is the number to use.

Who Alumo suits, and who should look elsewhere

Alumo suits a household that wants solar now, doesn't have the cash for a system, and wants to own it in the end. Three situations fit it best.

A homeowner with a mid-sized bill. If you pay R1 500 to R3 000 a month for electricity, Alumo's calculator suggests 4 to 10 panels, from R1 549 to R2 399 a month. That gets you backup and a smaller bill, with the servicing handled, and an Alumo quote sizes the system to your own bill.

A tenant. Alumo lets your landlord co-sign without taking on the payments, so you can have solar in a home you don't own.

A lodge, farm or small business that runs a kitchen, cold storage or pumps through the day and wants diesel off the books. The case studies above show the savings Alumo reports on that kind of site.

Alumo is the wrong fit in two cases. If you can pay for a system in one go, buying an installed kit costs much less than renting one for seven years, and Mzansi Solar is where I'd start. And if you only want the router and the TV on through a power cut, a battery backup or a portable power station is a far smaller spend. Every kind of backup power is compared in one place, and you can work out what size you need first.

If you're comparing Alumo with other solar companies, my ranking of nine of them puts Alumo first for most homes and prices the rest side by side, including Wetility's subscription for anyone who never wants to own the system.

So is Alumo Energy worth it?

Yes, for the reader it's built for. Alumo promises solar with nothing upfront, a system that becomes yours, and someone else looking after it, and on its own terms and its customers' reviews it delivers all three.

Choose Alumo's rent-to-own if you want to own the system and don't have the cash, and ask for the shortest term you can afford. Choose its subscription if you might move within a few years and would rather be able to cancel after 24 months. And if you run a lodge, farm or business, ask Alumo to design a system for your site.

When you ask for a quote, give your address and your average monthly bill, because those two decide the system Alumo prices for you.
