Uttar Pradesh is home to some of India's most significant textile clusters. Varanasi is synonymous with Banarasi silk weaving, Kanpur has a large power loom and garment manufacturing base, Mau is known for synthetic fabric production, and Muradabad has significant textile-related processing units. What these clusters share in 2026 is a growing electricity bill problem. UPPCL industrial tariffs have climbed to Rs 7-9 per unit, and power looms run on predictable, high-consumption daytime cycles that make them among the most natural candidates for rooftop solar in the state.
Understanding the Power Load Profile of a Weaving Shed
A typical power loom shed runs multiple looms simultaneously during daylight hours. A single automatic loom draws roughly 1-2 kW of connected load. A small shed with 10 looms has a load of 10-20 kW; a medium operation with 25-30 looms has a daytime load of 25-60 kW depending on the type of fabric and loom speed. Lighting, fans, humidifiers, and auxiliary equipment add another 10-20 percent to the load. The load profile is highly predictable and concentrated between roughly 7 am and 7 pm.
This predictability is exactly what makes weaving units ideal for solar. The peak generation window for a solar system in eastern UP, typically 9 am to 4 pm, aligns precisely with the hours when a working loom shed draws the most power. Unlike residential customers who use most electricity at night, a weaving shed can consume almost all of its solar generation directly on-site, avoiding the grid at peak tariff hours.
Why Solar Suits Textile Operations Better Than Most Businesses
Operational Hours Match Solar Hours
A single-shift weaving operation running 8 am to 6 pm will see its solar system generate the bulk of its output during exactly those hours. A 30 kW system in Varanasi generates roughly 120-150 units on a clear day, which at Rs 8 per unit represents Rs 960-1,200 in direct savings that day. Over a year with seasonal variation, a well-sized system achieves 85-90 percent direct self-consumption, meaning very little exported energy goes to waste.
Grid Unreliability in Eastern UP
Power loom operators in Varanasi, Mau, and surrounding districts regularly deal with grid outages and voltage fluctuations that damage sensitive loom electronics and cause production stoppages. A solar plus battery combination reduces dependence on the grid during daytime hours, maintaining power supply for critical loads even when UPPCL supply is interrupted. This operational continuity benefit is separate from the energy cost saving and has real value in terms of reduced machine downtime and lower rejection rates.
3-Phase Connection Requirements
Industrial looms and large shed operations typically run on 3-phase power. Solar systems for these applications must be designed with 3-phase inverters or balanced 3-phase output configurations, which is standard for commercial and industrial solar installations above 5 kW. UPPCL commercial and industrial connections of this type can apply for net metering under the state's rooftop solar regulations, meaning any surplus units generated when the shed is not at full load are credited against the bill.
System Size Recommendations for Textile Units
Based on typical load profiles for UP weaving sheds, these are practical starting points for system sizing. A small unit with 8-15 looms and a daytime load of 15-25 kW benefits from a 15-20 kW solar system. A medium shed with 25-40 looms running 30-50 kW of load is well served by a 30-40 kW installation. A large production unit running 75 kW or more of continuous daytime load should consider 75-100 kW of solar capacity, sized to offset the base load while leaving headroom for expansion.
These figures assume south-facing rooftop area is available. A 30 kW system requires approximately 200-230 square metres of usable roof, which most medium sheds can accommodate.
ROI Example: 30 kW System in Varanasi
Consider a Banarasi silk weaving unit in Varanasi with a daytime load of 30-35 kW, running six days a week for approximately 280 working days per year. A 30 kW rooftop solar system costs approximately Rs 10-12 lakh installed in 2026. It generates roughly 3,600-4,200 units per month in Varanasi's solar conditions. At Rs 8 per unit avoided, that is Rs 28,800-33,600 per month in electricity savings. Allowing for a small net metering credit on surplus units during lower-production months, total annual savings range from Rs 3.2-3.8 lakh.
Simple payback on the Rs 10-12 lakh investment comes out to roughly 3-4 years before tax benefits. Adding the 40 percent accelerated depreciation under Section 32 of the Income Tax Act, which allows a Rs 4-4.8 lakh first-year tax deduction on the system, the effective payback for a tax-paying unit drops to 2.5-3.5 years. After that, the system produces electricity at near-zero marginal cost for another 20-plus years.
Government Schemes for Textile MSMEs
Textile and weaving units registered as MSMEs in UP have access to multiple support channels for solar adoption. The UP government periodically runs capital subsidy programs for MSME solar installations through UPNEDA and the MSME department. These subsidies, where available, can reduce the installed cost by 15-25 percent on top of the central government schemes. Weaving units in Varanasi, Mau, Kanpur, and Muradabad that are registered with the MSME ministry should check current scheme availability with UPNEDA before finalising their procurement, as scheme windows open and close during the financial year.
Sunwize works with textile units across UP to design systems that account for 3-phase load requirements, structural roof conditions typical of industrial sheds, and the full financial case including depreciation and available subsidies. For an industry where margins are tight and power costs are a significant variable expense, the shift to self-generated solar power is one of the most impactful financial decisions a weaving unit can make in 2026.
