Solar Installation Guide | Tirupur Areas 2026

Tirupur district is defined by its textile industry. Known globally as the knitwear capital of India, Tirupur exports garments worth over Rs.30,000 crore annually, powered by thousands of knitting, dyeing, bleaching, and garment manufacturing units that consume enormous quantities of electricity. This single-industry dominance creates a unique solar energy landscape — one where industrial solar is not just an opportunity but a competitive necessity for businesses facing electricity costs that directly impact export margins.

Beyond the textile hub, Tirupur district encompasses a diverse geography spanning from the agricultural plains of Dharapuram and Kangeyam to the foothill areas near Udumalpet. Each area has distinct solar requirements based on its economic activity, building types, and grid infrastructure.

Tristar Green Energy Solutions serves all areas of Tirupur district from our Coimbatore headquarters, located just 50 km from Tirupur city. We have completed multiple installations for textile units, commercial buildings, and residential properties across the district, and understand the specific requirements of industrial solar in the knitwear ecosystem — from HT connection optimisation to open access procurement.

Tirupur Town — The Knitwear Hub

The Area

Tirupur town is the epicentre of India's knitwear export industry. The town and its immediate surroundings host thousands of textile units ranging from small knitting job-work shops to massive integrated manufacturing facilities. The Tirupur Export Knitwear Industrial Complex (TEKIC), SIDCO industrial estates, and numerous private industrial areas form a dense manufacturing cluster.

Beyond textiles, Tirupur town has a growing residential sector, commercial establishments, and institutional buildings.

Industrial Solar for Textile Units

The textile industry's electricity consumption is staggering:

• Knitting units: 5,000-20,000 units/month (LT-3 connections, 3-phase)
• Dyeing and bleaching units: 20,000-100,000+ units/month (HT connections, massive water heating and process loads)
• Garment manufacturing units: 10,000-50,000 units/month (cutting, stitching, finishing, AC for quality control)
• Integrated mills: 50,000-500,000+ units/month (combining multiple processes)

At TANGEDCO commercial/industrial tariffs of Rs.7-9/unit (including demand charges for HT consumers), monthly electricity bills for medium to large textile units range from Rs.1.5 lakh to Rs.40+ lakh.

Solar system sizing for Tirupur textile units:

Unit Type	Monthly Consumption	Recommended Solar	Investment	Annual Savings	Payback
Small knitting unit	5,000-10,000 units	25-50kW	Rs.12-25L	Rs.3-6L	~4 yrs
Medium dyeing unit	30,000-60,000 units	100-200kW	Rs.45-95L	Rs.12-24L	~4 yrs
Large garment factory	50,000-100,000 units	200-500kW	Rs.85L-2.5Cr	Rs.20-50L	~3.5 yrs
Integrated mill	100,000-500,000 units	500kW-2MW	Rs.2.5-10Cr	Rs.50L-2Cr	~3.5 yrs

HT Connection Savings

Most medium and large Tirupur textile units operate on TANGEDCO HT connections. HT tariffs include:

• Energy charges: Rs.6.35-7.55/unit depending on category
• Demand charges: Rs.300-350/kVA/month
• Power factor surcharge/incentive: Based on maintained power factor
• Time-of-day tariff: Higher rates during peak hours (6pm-10pm)

Solar generation during daytime hours directly offsets the highest-cost consumption periods. For HT consumers, the demand charge reduction from solar is an additional benefit — by reducing peak daytime grid draw, solar can lower the recorded maximum demand, reducing demand charges.

Open Access Solar for Large Consumers

For Tirupur's largest textile units consuming over 12 lakh units annually (average 1 lakh units/month), open access solar offers even greater savings than rooftop solar alone:

• What is open access? The consumer procures solar power from an off-site solar plant (typically 1-10 MW) through the TANGEDCO grid, paying only transmission and wheeling charges
• Cost structure: Solar power at Rs.3-4/unit + wheeling charges of Rs.1.5-2/unit = total cost of Rs.4.5-6/unit vs grid tariff of Rs.7-9/unit
• Savings: Rs.2-4/unit on every unit procured through open access
• Scale: Open access is viable for consumers with connected load above 500 kVA or annual consumption above 12 lakh units

Tristar assists Tirupur's large textile units with both rooftop solar installation and open access procurement advisory, providing a comprehensive approach to reducing electricity costs.

Avinashi — Textile Processing and Residential

The Area

Avinashi, located between Tirupur and Coimbatore on NH544, is an important textile processing centre. The town hosts numerous dyeing and bleaching units, fabric processing factories, and a growing residential sector serving people who work in both Tirupur and Coimbatore.

Solar Profile

• Industrial: Dyeing and processing units in Avinashi's industrial areas consume 10,000-50,000+ units/month. Solar systems of 50-200kW provide strong returns
• Residential: New independent houses in expanding residential areas around Avinashi are well-suited for 3-5kW rooftop solar
• Commercial: Shops, restaurants, and commercial buildings along NH544 benefit from 5-25kW systems

Considerations

Avinashi's dyeing units present a specific opportunity: solar water heating. The dyeing process requires large quantities of hot water at 60-90 degrees Celsius. Solar thermal systems (evacuated tube collectors) can pre-heat water to 50-70 degrees, significantly reducing the electricity or steam required for the final heating stage. A combination of rooftop PV (for electrical loads) and solar thermal (for process water heating) delivers the maximum energy offset for dyeing units.

Palladam — Cotton Mills and Agriculture

The Area

Palladam, south of Tirupur, is a town with dual character. It is a centre for cotton ginning and textile-related manufacturing, and simultaneously an important agricultural area with cotton, coconut, and vegetable cultivation. The town sits at the intersection of the Tirupur textile belt and the Coimbatore agricultural belt.

Solar Profile

• Cotton ginning mills: High-capacity motors consuming 5,000-30,000 units/month. Solar systems of 25-100kW provide 3-4 year payback
• Agricultural: Cotton and coconut farming with pump sets eligible for PM-KUSUM solar pumps (90% subsidy)
• Residential: Growing residential sector with new houses suitable for 2-5kW solar systems
• Estimated residential cost after subsidy: Rs.80,000 (2kW) to Rs.2,12,000 (5kW)

Considerations

Palladam's cotton ginning mills operate seasonally (primarily October-March during cotton harvest season), which affects solar ROI calculations. Systems need to be sized based on year-round consumption, not just peak season. During the off-season, surplus solar generation is exported to the grid through net metering, maintaining value even when mill operations are reduced.

Udumalpet — Agricultural Belt and Hill Proximity

The Area

Udumalpet (Udumalaipettai) sits at the southern edge of Tirupur district, at the transition zone between the plains and the Anamalai Hills. The town is primarily agricultural — sugarcane, coconut, and banana cultivation dominate — with some textile-related industry and growing residential areas.

Solar Profile

• Agricultural: Extensive irrigation pump set usage for sugarcane and coconut. PM-KUSUM solar pumps (90% subsidy) are highly relevant
• Commercial: Moderate commercial activity with shops, hospitals, and educational institutions. 5-25kW systems provide good returns
• Residential: Independent houses in the expanding town area suitable for 2-5kW solar systems
• Tourism: Proximity to Amaravathi Dam and Indira Gandhi Wildlife Sanctuary drives some tourism-related hospitality

Considerations

Udumalpet's proximity to the hills means slightly higher rainfall during the southwest monsoon and occasional grid reliability issues in rural areas. For properties in the rural-hill fringe, hybrid systems with battery backup are recommended. The flat agricultural land around the town is suitable for ground-mount solar installations.

Dharapuram — Handloom Weaving and Agriculture

The Area

Dharapuram, in the eastern part of Tirupur district, has a rich handloom weaving tradition alongside significant agriculture. The town is known for its handloom sarees and cotton textiles, produced by thousands of small-scale weavers operating power looms from their homes and small workshops.

Solar Profile

• Power loom weaving: Individual weavers operate 2-4 power looms consuming 500-2,000 units/month. Small solar systems of 2-5kW can offset a significant portion of weaving electricity costs
• Agricultural: Dryland agriculture with cotton, millets, and pulses. Bore well pump sets for irrigation are eligible for PM-KUSUM
• Residential: Traditional residential areas with a mix of tile-roofed and RCC houses. 2-3kW systems for most homes
• Estimated residential cost after subsidy: Rs.80,000 (2kW) to Rs.1,12,000 (3kW)

Considerations

Dharapuram's power loom weavers represent a unique segment. Many weavers operate looms from home or attached workshops, meaning their electricity connection covers both domestic and productive use. A 3-5kW solar system can offset both household and loom electricity, providing double benefit. PM Surya Ghar subsidy applies to the residential component, while the productive-use savings add to the overall ROI.

Kangeyam — Agricultural Area and Cattle Farming

The Area

Kangeyam, located in the southeastern part of Tirupur district, is famous for its indigenous Kangeyam cattle breed and is primarily an agricultural area. The economy is built on dryland farming (cotton, millets, groundnut), cattle breeding, and dairy farming.

Solar Profile

• Agricultural: Extensive bore well irrigation with 3-7.5 HP pump sets. PM-KUSUM solar pumps are highly relevant for Kangeyam's farmers
• Dairy: Milk collection centres and small dairy processing units benefit from 5-15kW solar systems with battery backup for cold chain reliability
• Residential: Rural and semi-urban residential properties with 2-3kW system requirements
• Estimated residential cost after subsidy: Rs.80,000 (2kW) to Rs.1,12,000 (3kW)

Considerations

Kangeyam's dryland farming context means irrigation is critical and expensive. During the dry season (January-May), farmers operate pump sets for 8-12 hours daily, consuming substantial electricity. PM-KUSUM solar pumps eliminate this cost entirely, with the 90% subsidy making solar pumps accessible to small and marginal farmers.

The growing dairy cooperative movement in Kangeyam creates demand for cold chain solar solutions — solar-powered bulk milk coolers and cold rooms that maintain milk quality while reducing electricity costs.

Textile Industry-Specific: Dyeing Industry Water Heating with Solar

Tirupur's dyeing and bleaching industry deserves special attention because water heating is its single largest energy expense. The dyeing process requires water at temperatures ranging from 40 degrees to 100 degrees Celsius, consuming enormous quantities of thermal energy.

Current Water Heating Methods

• Steam boilers (coal/biomass): Most common for large units. High fuel costs, pollution concerns, and upcoming emission regulations
• Electric heaters: Direct electrical heating using immersion or flow-through heaters. Very high electricity costs at Rs.7-9/unit
• Diesel/furnace oil heaters: High fuel costs and environmental impact

Solar Thermal Water Heating for Dyeing Units

Solar thermal collectors — particularly evacuated tube collectors (ETC) — can pre-heat process water to 60-80 degrees Celsius using solar energy, significantly reducing the fuel or electricity required for final heating.

Typical solar thermal system for a Tirupur dyeing unit:

• System size: 100-500 evacuated tubes (equivalent to 5,000-25,000 litres/day hot water)
• Investment: Rs.3-15 lakh depending on scale
• Water temperature achieved: 60-80 degrees Celsius (solar only), boosted to process temperature using existing heating system
• Fuel savings: 30-50% reduction in coal/diesel/electricity for water heating
• Payback: 2-3 years

Combined PV + Solar Thermal Approach:

Tristar recommends a combined approach for Tirupur dyeing units:

1. Rooftop solar PV (50-200kW) for electrical loads — motors, lighting, compressors, pumps
2. Solar thermal collectors for process water pre-heating
3. Result: Total energy cost reduction of 40-60%

This combined approach maximises the utilisation of available roof space and addresses both electrical and thermal energy needs.
