Solar for Factories
Factories with daytime shifts can use much of their solar output on site, making rooftop plants a common first step.
Checklist before planning
- 12 months of electricity bills and demand data
- Roof type, age and load-bearing capacity
- Shading from equipment or structures
- Sanctioned load and metering arrangements
Technical concerns
Large plants interact with the plant electrical system. Protection, harmonics and fault levels need engineering review.
Business view
Evaluate with your own tariff and quote using our ROI calculator, and consider maintenance in the long-term case.
Typical factory project timeline considerations
Industrial projects take longer than homes because of structural audits, approvals and equipment lead times. Plan shutdown windows early, align procurement with site readiness and agree testing steps up front. Keep a clear handover package with drawings, test records, warranties and operation instructions.
Aligning solar with shifts
Single-shift plants use almost all output directly. Multi-shift plants use less of it during peak sunlight, so the benefit per kW varies. Share your shift pattern at the first discussion.
Frequently asked questions
Will solar disturb my production?
A well-designed grid-tied plant should not, but design review is essential.
Do I need permission from the DISCOM?
Grid-connected plants generally need approvals. Confirm for your category.
