Running a Factory on Sunlight: Our Solar Transition

How large-scale solar is cutting scope 1 and 2 emissions across our production lines.

Garment factories run on electricity. Knitting machines, sewing lines, cutting tables, compressors, lighting and cooling all draw power for every hour of every shift. For most of our history, that power came from the grid and from backup generators, both heavily dependent on fossil fuels.

Moving to solar is the biggest single step we've taken to cut the emissions behind every garment we make. Here's why we did it, how it works and what it means for brands sourcing from us.

Why solar, and why now

Pakistan gets strong sunshine for most of the year, and Punjab is no exception. At the same time, grid electricity prices have risen sharply and supply has been unreliable, with outages forcing factories to fall back on diesel generators. Solar lets us generate our own clean power on site, during the daytime hours when our lines are busiest.

There's also growing pressure from the brands we work with. Many now report on the emissions in their supply chain, and they need suppliers who can show real reductions.

Understanding scope 1 and 2

Emissions are grouped into three scopes:

  • Scope 1: direct emissions from sources we own, like diesel generators and boilers.
  • Scope 2: indirect emissions from the electricity we buy from the grid.
  • Scope 3: everything else in the value chain, including our clients' supply chain emissions, which our factory emissions become part of.

Solar cuts scope 2 by replacing grid electricity, and scope 1 by reducing how often we run generators. For our clients, that lowers the scope 3 footprint of every product they buy from us.

“Every kilowatt-hour from our roof is one that doesn't come from a generator or a gas-fired plant.”

How the system works

Solar panels across our factory roofs feed power into inverters, which convert it for use on the production floor. During the day, solar supplies a large share of our electricity. When demand exceeds what the panels produce, or after sunset, the grid makes up the difference.

We monitor generation and consumption continuously, so we can see how much of each day's power came from the sun and adjust energy-heavy processes to run during peak generation where possible.

Beyond the panels

Generating clean power is only half the job. Using less of it matters just as much. Alongside solar, we've been:

  • Replacing older motors on sewing machines with energy-efficient servo motors.
  • Switching lighting across the factory to LED.
  • Fixing compressed air leaks, one of the most common hidden energy losses in factories.
  • Tracking energy use per garment so improvements can be measured.

What it means for your brand

Lower emissions at the factory mean a lower footprint for your products. We can share energy and generation data to support your sustainability reporting and supplier assessments, and we're happy to talk through the numbers behind your specific orders.

Key takeaways
  1. Rooftop solar supplies a large share of daytime power, when production lines are busiest.
  2. Solar cuts scope 2 by replacing grid power and scope 1 by reducing generator use.
  3. Lower factory emissions reduce the scope 3 footprint of every garment our clients buy.
  4. Efficiency upgrades like servo motors and LED lighting cut demand alongside clean generation.

FAQ

Does solar power the factory at night?

No. After sunset, and when demand exceeds generation, the grid supplies the difference.

Can you share energy data for our reporting?

Yes. We can share solar generation and energy consumption data to support your emissions reporting.

Does solar affect pricing or lead times?

No. If anything, more stable on-site power means fewer disruptions from grid outages.

What are you doing about scope 3?

Our solar and efficiency work lowers the emissions our clients count as their scope 3. We also work with fabric and trim suppliers on lower-impact materials.
