Why Knitting Units Are Perfect Solar Candidates
Purely Electrical Loads
Unlike dyeing units (which also burn gas for steam), knitting machines run entirely on electricity. Every rupee saved on electricity directly reduces your production cost. Solar self-consumption rates for knitting units running day shifts are typically 85–95%.
Predictable Load Profile
Knitting machines run at near-constant load once spinning. The electricity consumption profile is smooth and predictable — making solar sizing straightforward and ROI calculations highly accurate. No large motor-start spikes or batch-process variability to account for.
Available Roof Space
Knitting halls are large, low-rise structures with flat or slightly pitched roofs — ideal for solar. Even a 50m × 40m shed provides 2,000 m² of panel space, enough for a 200kW system. Multi-shed operations can install 500kW–1MW+.
Competitive Solar Economics
At Rs. 42–55/unit industrial tariff, a 200kW solar system generating 25,000 kWh/month of solar saves Rs. 1.0–1.4M/month. At Rs. 36M installed cost, payback is 2.5–3 years. Then 22+ years of near-free daytime electricity — a transformational competitive advantage.
Solar Sizing Guide — Knitting Units
| Unit Scale | Machines (Approx.) | Recommended Solar | Est. Monthly Saving | Approx. Payback |
|---|---|---|---|---|
| Small unit | 10–25 circular machines | 50–100 kW | Rs. 400K–800K | 3–4 yr |
| Medium unit | 25–60 circular machines | 100–250 kW | Rs. 800K–2M | 3–4 yr |
| Large unit | 60–150 machines | 250–500 kW | Rs. 2–4M | 2.5–3.5 yr |
| Integrated knitting + cutting | 150+ machines + sewing lines | 500kW–1MW+ | Rs. 4M+ | 2.5–3.5 yr |

Specific Solar Solutions for Knitting Sub-Sectors
Circular Knitting Units
Single jersey, double jersey, and rib knitting machines each consume 2–8 kW. A 50-machine circular knitting hall draws 150–300 kW continuously. Solar covers this cleanly with a 100–200kW rooftop system, leaving a buffer for auxiliary loads and future expansion.
Recommended: 100–200kW on-grid 3-phase systemFlat Knitting & CNC Knitting
Modern computerised flat knitting machines (Shima Seiki, Stoll, Brother) draw 3–12 kW each. They run predominantly in day shifts due to operator requirements. Solar aligns near-perfectly with their operation schedule, achieving 90%+ self-consumption rates.
Recommended: 50–150kW system matching machine countHosiery & Sock Manufacturing
Hosiery machines are typically smaller (0.5–3 kW each) but facilities run 100–500 machines simultaneously. Total load of 200–800 kW with high ancillary load from linking machines, boarding, and packaging. Solar offsets 50–70% of these loads efficiently.
Recommended: 100–400kW based on machine countOur Installation Process for Knitting Units
Free Load Analysis
Share 12 months of WAPDA bills. We calculate exact solar savings, determine optimal system size, and prepare an ROI projection — before you commit to anything.
Site Survey
Our engineers visit your facility to measure roof space, assess structure, check panel orientation, and plan cable routing to the main distribution board. Takes 1–2 hours with no disruption to your operations.
Installation (1–5 Days)
LONGi panels mounted on galvanised steel structures. 3-phase string inverters installed in a suitable indoor location. DC and AC cabling run in cable trays. Most knitting unit installations complete in 2–3 working days.
WAPDA Net Metering
We prepare and submit the complete net billing application, coordinate WAPDA meter installation, and follow up until activation. You start exporting surplus to the grid and see credits on your next bill.
