Industrial Solar Solutions for Automotive Manufacturing
Bigfisch designs industrial solar and battery systems for automotive assembly and component plants, sized around continuous three-phase loads, critical production equipment and the site's actual energy profile.
Battery storage can be configured to support critical loads during grid faults and load-shedding, helping reduce the risk of production interruption when correctly sized and commissioned for the plant's requirements.
Industrial solar solutions can keep a continuous automotive assembly line running, provided the system and battery storage are sized to your continuous three-phase load, not just average consumption. Battery capacity is matched to the loads that cannot tolerate a gap, so the line keeps running through loadshedding stages and grid faults.
158kWp to 578kWp of continuous-load industrial solar already installed and running across Southern African manufacturing sites.
Why automotive plants choose Bigfisch for Industrial Solar
- Systems sized to your continuous three-phase loads and critical battery backup, not a generic industrial package.
- A documented, metered installation your sustainability team can report directly against OEM Scope 2 targets.
- Protection against the real cost of a stopped line, lost production time and committed labour, not just the electricity bill.

Why a stopped line costs more than the power bill
Automotive assembly runs on precision and predictability. A brief interruption does not just cost the electricity used, it costs the production time, the labour already committed, and in some cases rework further down the line. On a mid-sized assembly plant, downtime like this adds up quickly in lost production time and committed labour costs before a single unit is scrapped for rework. Every hour the line is down also pushes up the cost per unit produced that day, the metric most plants are measured against. That makes the energy reliability a production planning issue as much as a cost one.
Industrial Solar solutions for continuous three-phase load
We size systems around your three-phase load profile, not a generic industrial package, so battery storage carries the loads that cannot stop through loadshedding and grid faults. Inverter capacity is matched to peak demand, and battery capacity to the critical load that must keep running, oversizing wastes capital, undersizing leaves your line exposed.
Every system specifies tier-1 components built for continuous industrial duty. Jinko Solar panels, Solis hybrid inverters and Sunwoda lithium batteries, not a residential-grade package.

Power quality in the paint shop and on the line
Voltage dips and power quality issues can affect paint finish and assembly precision in ways a standard energy audit will not catch. We factor power quality into the system design, not just total kWh offset, so the parts of your line most sensitive to a dip in supply are the parts best protected.
Solar and Scope 2 reporting to meet OEM sustainability requirements
Automotive OEMs increasingly push Scope 2 (purchased electricity) and Scope 3 (supply chain) emission targets down to their suppliers. A documented, metered solar installation gives your sustainability team a concrete, reportable reduction, rather than a policy statement. For a global OEM’s supply chain reporting, a metered figure also stands up better under audit than a policy statement alone.
Qualifying installations may also be eligible for Section 12B deduction on qualifying renewable energy assets. Confirm your eligibility for your specific plant structure with your tax advisor.
Bigfisch cannot guarantee Section 12B deductions or payouts; eligibility depends on your tax position, so confirm with your tax adviser.
Funding the system without tying up working capital
A capital solar purchase isn’t the only route: cash purchase, asset finance, and lease-based options can all be structured around your plant’s capital position and how you’d rather treat the asset on the balance sheet. SSEG Registration and municipal grid compliance are handled by us as part of the project.

Frequently Asked Questions
Can solar power a continuous assembly line without interruption?
Yes, when the system and battery storage are sized to your actual continuous load, not just average consumption. The design accounts for the loads that cannot tolerate any gap.
How does solar support our Scope 2 emissions reporting?
A metered solar installation gives your sustainability team a documented, verifiable reduction in grid-sourced electricity, which can be reported directly against Scope 2 targets.
What size system does an assembly plant typically need?
Most automotive assembly and component plants need systems in the 100kW to 500kW+ range, depending on continuous load and available roof or ground space. A site assessment confirms the exact size for your specific line.
How long does a solar and battery system for an assembly plant typically take to pay back?
Payback depends on your current tariff, continuous load and system size, there is no single figure across all automotive plants. A site assessment gives you a firm number for your specific plant.
Can an older plant’s roof or site carry a solar installation without disrupting production?
A structural review is part of every site assessment, covering roof condition, ground space, and existing electrical infrastructure before any design work starts.
Does Bigfisch have experience with automotive-scale installations specifically?
Bigfisch has installed and commissioned continuous-load industrial solar from 158kWp to 578kWp across Southern African manufacturing sites. A site assessment shows what a single-scale system means for your plant.
