One of the best rent-to-own offerings

Our Rent-to-Own option through Merchant West for businesses and individuals is one of the best rent-to-own offerings in our view. Here’s why:

Look before you leap into solar rental contracts – some are outright exploitative

If ever there was a cautionary tale, this is it. There are many solar rental and ‘solar as a service’ (SaaS) subscription options that have sprung onto the market that promise the world, while a deeper delve into the contract fine print leaves you cold with hefty initiation fees, onerous annual escalations, never-ending ‘ever-green’ rental terms, hefty penalties for early cancellations, de-installation costs and large buy-out clauses to own the asset after the rental period – many are simply not financially savvy at all. 

Analyse the T&Cs thoroughly

While cash/outright purchase is always first prize, it’s simply not practical or affordable for many people on higher asset values – that’s where solar rent-to-own options are especially helpful. There is of course a big caveat – carefully analyse the terms and conditions, escalations and penalties as not all rental deals are created equally.  

Always remember your primary motivation for going solar – to radically reduce your grid electricity costs and financial obligations by taking control of your electricity supply and self-generation – not to create new financial obligations by getting blind-sided into a rental subscription agreement that turns out to be a serious liability. 

One Energy provides a helpful checklist of aspects to interrogate before going into any solar rental agreement:

  • A quality hybrid solar system has a good 20-year lifespan, so ideally you want to take full ownership of your system, pay it off quickly and really get the best return on investment on your system. If you pay your system off in 5 or 6 years, you have a good 15 years of free electricity production from your solar PV system. Look to finance or rent-to-own your system over fixed term, but beware of onerous ‘buy-out’ clauses on some rent-to-own options. We cannot emphasize enough the importance of interrogating all the terms and conditions – ask for a sample contract before you sign up and actually work out the financials and do the sums. 
  • Be wary of entering into solar-as-a-service (SaaS) rentals or subscriptions without doing the math. It makes little financial sense to pay for solar-supplied energy (kW) where the rental/subscription costs increase annually by around 7%, alongside Eskom’s charges increasing alongside this every year by around 15%. Unless your system is sized to reduce your grid usage by at least 90% or more, you could be in a world of pain with your solar supplied power costing you much more than when you started after 3 years of escalations.
  • Solar subscription agreements that last a fixed term, like 5 years for example, and escalate annually, mean that at the end of 5 years you do not own the system and have absolutely nothing to show for the payments made over five years – essentially you simply bought the solar kW per month. Here’s the real clanger – when we took one of the subscription packages and analysed what such a system would actually generate in terms of kW per day – in this particular example it was 25kW – multiplied this by 30 to get the monthly generation capacity (750kW), and then divided this by the monthly rental amount, the cost per kW was R3,80 – much higher than Eskom/council cost per kW!  To add insult to injury, this cost then increases by 7% every year, for the same amount of generation.


Why would you want to pay away a monthly premium for 5 years for pure consumption kW when you can actually own the asset that will be productive for many more years and save you a fortune? On a system that would have cost you R184k on a cash purchase, you end up paying R250k after 5 years on a solar subscription – that’s a R66k premium – on equipment that still has at least another 10-year+ lifespan – and you have nothing to show for it. And you’re paying more per kW than your council charges.  Do the math!   

  • Of the solar rental offerings on the market which we analysed, all rental contracts increase the monthly instalments by between 5% – 7.5% upon the annual anniversary of the contract. This means that a monthly rental payment of around R1500 per month in year 1 will escalate each year by around 7% compounded. By year six of your contract (72 months), you will be paying almost R800 per month more! 


The point is you are looking to get your electricity at a cheaper rate than what you can buy from your council or Eskom – an ever-increasing solar rental completely defeats this objective. While these deals may sound cheap to start off with, they soon rapidly escalate as the years go on. Remember that you are also still likely to be drawing some electricity from the grid as it is very unlikely that you will be off-grid completely. Given that electricity prices are likely to increase by at least 12-15% per annum for the foreseeable future, and if your monthly solar rental increases each year by 7% – in essence you could be facing a serious financial liability. 

  • Carefully review penalty fees for early cancellation or if you want to buy out your system before the end of the rental period – these vary from supplier to supplier but can be very hefty penalty fees. 
  • If you’re on a solar subscription, the solar development company owns the equipment and not the homeowner, so any benefit on rebates, incentives and feed-in tariffs goes back to the equipment owner, and not to you. This is a big sticking point.
  • Is the solar subscription provider a solar installation specialist with inhouse technical expertise and qualified service teams, or are they simply a lead generator that outsources the installation to a panel of independent solar installation partners? It may not seem important upfront, but down the line when you need service and back up support for a technical or warranty issue, this can be a significant sticking point as to who services your needs.   

What can I expect to save with a solar PV system?

Residential Case Study

Consider the following residential example on a current electricity bill of R3000 (around 900kWh per month based on Ekurhuleni tariff of R3,30/kWh).

  • You invest in a 5kW hybrid inverter, with 10kWh of battery back-up and a 5.4kW solar array for R141k.
  • Your PV system will generate on average 27kW per day and 815kW per month. 
  • Your batteries will provide 9kWh or usable back-up power to carry your essential and night-time loads.  
  • Your solar system will take you around 90% off the grid – in other words save you 90% on what you would need from the grid – in monetary terms, that’s around R2670/pm that you will not be paying on your municipal electricity account. That’s R32 000 per year.
  • Your solar system will fully pay for itself in just over 4 years. Considering that your system is likely to be productive for another 15+ years, that’s a phenomenal investment in your grid independence and massive savings for your pocket.  
  • On a rent-to-own option, over 72 months, your monthly repayments will be around R3100 per month (subject to your credit rating and rates applied), with no annual escalation – which is almost amortised by your monthly savings on your electricity costs.
  • Consider that with no intervention, you will have spent R280k on grid-electricity costs over five years. That’s double the cost of your R141k solar system, with absolutely zero return on investment or ongoing financial benefit to you.


So how do we get to less than R1.00 / kWH fixed for 20 years? 

  • Using the 815 kW per month above, you will generate 9780 kW in the first year. 
  • At a 1% efficiency decline per annum, you will generate 80% of this – 7824 kW in year 20.
  • So the average over 20 years is 8802 kW per annum x 20 = 176 040 kW over 20 years. 
  • The cost of the system is R141 000 so the average cost per kWh is R0,80 – that’s 80 cents  fixed for 20 years. And even after 20 years, your system will still run at 80% of the initial efficiency. 

Commercial Case Study

Consider the following commercial example of a small business with current electricity bill of R16 500 (around 5000kW per month) based on Ekurhuleni tariff of R3,30/kWh).

  • You invest in a 30kW hybrid inverter, with 32kWh of battery back-up and a 30kW solar array for R510k.
  • Your PV system will generate on average 150kW per day and 4500kW per month.  
  • Your batteries will provide 26kWh of usable back-up power to carry your essential and night-time loads.  
  • Your solar system will take you around 95% off the grid – in other words save you 95% on what you would need from the grid – in monetary terms, that’s around R14 850/pm that you will not be paying on your municipal electricity account. That’s R178 200 per year.
  • Your solar system will fully pay for itself in just under 3 years! Considering that your system is likely to be highly productive for a good 20 years, that’s a phenomenal investment in your grid independence and massive savings for your business. And you will have secured your electricity costs and security of supply for your business. 
  • Consider that with no intervention, you will have spent R1.4million on grid-electricity costs over five years. That’s almost three times the cost of your solar PV system, with absolutely zero return on investment or ongoing financial benefit to your business.
  • On our rent-to-own option for business through Merchant West, over 72 months, your monthly repayments will be around R11 000 per month (subject to your business credit rating and interest rates applied) – which is much less than what you are saving on monthly electricity costs! 
  • Your monthly rental payments are fully amortised by your monthly savings on your electricity costs with R3000 spare change, you fully own the system at the end of the rent-to-own period with the payment of just one month’s additional rental, and there is no annual escalation in the rental with One Energy’s rent-to-own solution through Merchant West. 
  • As another big financial incentive, your business can take advantage of the Section 12B tax incentive.  Section 12B of the Income Tax Act No. 58 of 1962 allows for a tax deduction in respect of certain qualifying assets (owned and brought into use after 1 January 2016) to reduce the taxable income of the taxpayer. These qualifying assets must be used for purposes of trade in the generation of electricity from renewable sources. For the period 1 March 2023 to 28 February 2025, the Section 12B allowance has been increased from 100% to 125% and no maximum cap on the output of the solar installation.
  • If your business is VAT registered, you can claim/offset the input VAT back against your output Vat for the business.

Still think it’s not worth your while to redirect the money you would be spending on grid electricity to your own solar PV system for your business?
