The honest answer to "how much does solar cost?" is it depends — on the size of your home, how much backup you want, and the state of your existing electrics. But that's not very helpful when you're trying to budget. So here are real, installed prices for solar systems in Bloemfontein in 2026, what actually drives the number up or down, and how soon a system pays for itself.
The short version
- A complete, installed home system in Bloemfontein runs from about R99,000 to around R245,000.
- The battery is usually the single biggest cost — more backup means a higher price.
- Panel-only prices you see online are a fraction of what a working, compliant system costs.
- For your exact figure, use our solar calculator or request a site visit.
What you're actually paying for
A solar quote is never just panels. A complete installation bundles several parts, and each one moves the price:
- Solar panels. The most visible part, but often a smaller slice of the total than people expect. Tier-1 panels cost more than no-name ones, and last longer.
- The inverter. The brain of the system — it converts solar and battery power for your home. Its size (5kW, 8kW, 12kW) is set by how much power you use at once.
- The battery. Usually the biggest single cost, and the main reason two quotes differ. More stored backup (6kWh vs 18kWh) means a higher price.
- Mounting, cabling and installation. Roof brackets, wiring, protection and the labour to fit it all safely.
- Electrical compliance. Any remedial work to bring your DB board and wiring up to standard, plus the Certificate of Compliance that makes the system legal and insurable.
That last point matters. Our registered electricians in Bloemfontein handle the compliance side in-house, so the system is signed off correctly — not left for you to sort out later.
Why "cheap panels online" is misleading
Search for solar panels and you'll find prices that look surprisingly low. The catch: a panel on its own does nothing. To power your home through load-shedding or after dark, you need an inverter, a battery, mounting, protection, professional installation and compliance sign-off. The panels are often one of the smaller line items. So when you compare the price of a bare panel to a full quote, you're comparing a single ingredient to a finished meal.

These are Del Group's own package prices — the same ones behind our solar savings calculator. They're indicative installed prices to help you budget; your exact figure depends on your roof, your usage and any electrical remedial work, so a site visit gives the firm number.
| System (inverter + battery) | From | Typically suits |
|---|---|---|
| 5kW + 6kWh | R99,000 | Lower-use home around 300–500 kWh/month, backing up essentials like fridge, lights, plugs, Wi-Fi and TV while geyser, stove and pool pump are managed separately. |
| 5kW + 9kWh | R119,000 | Average home around 400–650 kWh/month that needs essential-load backup with a longer evening and overnight battery buffer. |
| 8kW + 9kWh | R139,000 | Medium-use home around 600–900 kWh/month needing more simultaneous power for daytime loads, appliances, pumps or occasional aircon use. |
| 8kW + 18kWh | R159,000 | Higher-use family home around 800–1,200 kWh/month wanting stronger evening backup and better overnight coverage for essential loads. |
| 12kW + 9kWh | R169,000 | High-demand home or light three-phase setup around 900–1,300 kWh/month where peak power matters more than long battery runtime. |
| 12kW + 18kWh | R199,000 | Large home or small business around 1,200–1,700 kWh/month needing both high daytime capacity and meaningful night-time backup. |
| 12kW + 27kWh | R245,000 | Very high-use home or small business above 1,500 kWh/month, or a near off-grid setup needing long evening and overnight autonomy. |
Not sure which row is you? Most Bloemfontein homes land on a 5kW or 8kW system — the solar calculator matches your monthly bill to the best-fitting options, or our solar installers in Bloemfontein can size it for you on site.
When does solar pay for itself?
Solar is a purchase that pays you back. Three things decide how fast: the size of your electricity bill, how much of your own solar power you actually use, and the tariff you'd otherwise be paying. The bigger your bill and the more of your generation you consume, the quicker the system pays for itself — and with Centlec tariffs climbing year after year, the savings grow over time rather than shrink.
Rather than guess, put your own numbers in: our solar savings calculator estimates your monthly savings and payback period from your current electricity bill.
Bringing the cost down
A few practical ways to make solar more affordable without cutting the corners that matter:
- Finance it. Del Group works with financing partners, so you can spread the cost — often close to what you're already paying for electricity. Ask about options during your consultation.
- Start right-sized, expand later. A well-designed system can be grown. Begin with the inverter and battery that fit your real usage, and add panels or storage down the line.
- Don't skimp on compliance. Skipping the COC to save money is a false economy — it can void insurance, block a future property sale, or land you with fines.
"The cheapest quote is rarely the cheapest system — a small battery and skipped compliance cost you later."
Why one quote costs more than another
If you're comparing solar quotes, the price gap usually comes down to four things: battery size (the biggest swing), the quality of the components (Tier-1 panels and reputable inverters cost more but last longer and carry better warranties), the inverter size, and whether the quote includes full electrical compliance and certification. A suspiciously cheap quote often means a smaller battery, lesser-known gear, or compliance left out. Always compare like for like.
