Solar for Manufacturing and Factories in Southern Africa
Industrial solar and battery systems designed around your production load, energy costs and uptime requirements.
Solar solutions can cut a Southern African factory’s grid energy costs and keep production running through loadshedding when battery storage is sized to the site’s critical load. Bigfisch models the system against your actual consumption profile and load-shedding stage, then documents levelised cost, payback and ROI so the numbers, not a sales pitch, make the commercial case.
Why manufacturers are investing in solar and battery storage
Downtime on a production line costs more than the electricity bill, and on manufacturing margins this thin, energy is one of the few costs still within your control. Bigfisch designs and builds industrial solar solutions: solar and battery systems that put the large roof and ground space most factories already own and rarely use to work, protecting uptime, cutting opex and giving the board numbers over ten years, not a sales pitch.
Bigfisch is also one of the few solar partners in this market publishing real LCOE, IRR and payback figures up front.

Protecting manufacturing uptime
- Uptime protection: battery storage sized to your critical load keeps the line running through load shedding.
- Competitive cost advantage: our proposals model the levelised cost of solar against your actual consumption profile, tariff structure and system design.
- Financing that fits your balance sheet: outright purchase, PPA or lease, with the total cost of ownership walked through for each.
We are the accessible mid-scale industrial specialist who knows opex, downtime cost and payback.
Solar Configurations for factories
Most factory buildings already have the roof or land area a commercial solar system needs, sitting unused. Our site assessment doubles as an energy audit of your load profile, roof condition, and available ground space, so the recommendation is sized to your building and your consumption, not generic guesswork.
Rooftop solar for roofs
We assess structural capacity and orientation as part of the feasibility study, so the system fits the building rather than the other way round. For older or brownfield sites, that same assessment flags any structural reinforcement the roof needs before installation, so the cost is priced in upfront rather than around mid-project.
Ground-mount for larger sites
Where roof space is limited or unsuitable, ground-mounted arrays on adjacent land can scale to a larger system than a roof alone would allow, suited to sites with high continuous draw.
Solar carports
A carport structure generates power while doing a second job: shading vehicles and staff parking. It is an underused option where roof space is constrained but a parking area is not.
Our 102 kWp carport installation for Centurion Systems paired this with diesel backup, keeping the site running through loadshedding.

Power Factor: The hidden cost of industrial energy bills
Reactive power and poor power factor quietly add penalty charges to many industrial electricity bills, separate from the rate per kWh. It is a technical detail more competitors do not raise, but it is often a meaningful part of a factory’s total energy spend and worth reviewing alongside any solar proposal rather than after the fact.
Bigfisch reviews power factor as part of every site assessment, with any correction cost priced in alongside the solar proposal.
Eskom’s 2026/27 tariff structure shows that large-power customers can face separate energy, capacity, network-demand and reactive-energy charges, with reactive-energy charges applying under specific conditions.
Real Project Economics: LCOE, IRR, NPV and Payback
We do not deal in vague promises.
Across our commercial and industrial installations, the levelised cost of solar energy typically runs at R0.45 to R0.50 per kWh, a fraction of current grid tariffs, with system costs modelled against your consumption profile.
All our proposals include the IRR, NPV and payback period, all of which a finance team needs to evaluate the project alongside any other capital expenditure, backed by full technical spec sheets for the equipment specified.
As one example, a 100kW/240kWh system typically pays back in three years and nine months, with a 570% return over 20 years, at a modelled LCOE of R0.475 per kWh, giving a finance team a concrete industrial solar ROI benchmark rather than a rule of thumb.
Financing: CAPEX, PPA or lease.
Not every manufacturer wants to spend capital upfront, and we understand that. Bigfisch structures financing around whichever model suits your balance sheet, whether that is an outright purchase to claim the Section 12B tax allowance (subject to the applicable tax rules and the project’s eligibility), a power purchase agreement, or a lease, and can walk your finance team through the total cost of ownership for each.
Bigfisch cannot guarantee Section 12B deductions or payouts; eligibility depends on your tax position, so confirm with your tax adviser.
You can see the full breakdown of CAPEX, PPA and lease options on our Solar as a Service page.

Why manufacturers are investing in solar and battery storage
Greencape’s 2025 Energy Services Market Intelligence Report identifies cost savings, price stability, energy security and decarbonisation as key drivers for embedded solar PV and behind-the-meter battery storage in South African commercial and industrial businesses.
Proven on Southern African Factory Floors
Our manufacturing portfolio includes a 158 kWp installation for a steel production plant, a 102 kWp solar carport paired with diesel backup for Centurion Systems that kept operations on point, and further 578 kWp and 644 kWp installations across manufacturing and food production sites.
SSEG and grid compliance
Every project is delivered end to end, with a feasibility study, financing structure, EPC delivery, SSEG grid compliance and ongoing operations and maintenance. Commercial solar for factories then stays one point of accountability, not a handoff between contractors.

Frequently Asked Questions
Will a grid-tied manufacturing solar system require SSEG approval?
Depending on the system and the requirements of the relevant municipality or network operator, an embedded-generation application and grid-compliance process may be required. Bigfisch can manage the applicable SSEG process as part of the project.
Can solar keep a continuous production line running through loadshedding?
A suitably designed battery system can protect defined critical loads during grid interruptions. The protected load, duration and system configuration depend on the site’s load profile, battery capacity and operating requirements.
Rooftop, ground-mount or carport, how do we decide?
It comes down to available roof condition, land, and how much shading or dual-use value a carport would add. Our site assessment covers all three, so the recommendation is based on your site, not a default option.
What is the payback period and ROI for a factory solar installation?
It depends on the system size, current tariff and consumption profile; all our proposals include IRR, NPV and payback modelling for your site.
Should we buy outright, use a PPA or lease?
That depends on your balance sheet and whether claiming the Section 12B tax allowance matters to your finance team. We walk through the total cost of ownership for each option before you decide. See the full CAPEX/PPA/lease comparison on our Solar as a Service page.
