Calculate your Sahiwal system size →
Sahiwal sits in the heart of Punjab’s agricultural belt. The local economy runs on farming, dairy, and food processing. Electricity demand is driven by residential cooling loads in summer and agricultural tubewells that run year-round. MEPCO serves the area with tariffs that have increased steadily and load shedding that makes grid power unreliable for both homes and farms. Solar addresses both problems at once.
Sahiwal receives 5.0-5.4 peak sun hours daily. The flat terrain of southern Punjab means minimal shading from topography. Summer temperatures push past 45 degrees Celsius, causing some thermal derating, but the long daylight hours compensate with extended generation windows. The climate is well-suited for solar, with clear skies for roughly 280 days per year.
MEPCO residential tariffs range from Rs. 50-63 per unit at upper slabs. Agricultural tubewell tariffs are subsidised but still represent a significant expense for farmers running pumps 6-10 hours daily. Solar eliminates or drastically reduces both.
Agricultural tubewells are a major use case. Farmers running 10-25HP pumps spend PKR 30,000-80,000 monthly on electricity or diesel. Solar-powered tubewells eliminate that cost entirely. Residential homes in Sahiwal city are the other growing segment, particularly families in higher consumption brackets with monthly bills exceeding PKR 25,000. Small commercial properties including shops, warehouses, and cold storage facilities are also adopting solar to reduce operating costs.
• Residential: 5-10kW hybrid system
• Residential (large): 10-15kW hybrid system
• Agricultural tubewell: 15-30kW solar pump system
• Commercial: 20-50kW on-grid system
Hybrid systems are recommended for homes due to MEPCO load shedding of 4-6 hours daily. Battery backup keeps fans and ACs running through outages. For tubewells, dedicated solar pump systems with variable frequency drives (VFDs) operate directly from solar panels without batteries, reducing cost and maintenance. Commercial installations benefit from on-grid net metering to offset daytime consumption.
A 10kW residential system generates approximately 1,200-1,400 units per month. At MEPCO upper-slab rates, that saves PKR 35,000-55,000 monthly. A 20kW tubewell system eliminates PKR 40,000-70,000 in monthly electricity or diesel costs. Payback for residential systems is 3.5-4.5 years. Tubewell systems often pay back in 3 years or less due to the high avoided cost of diesel pumping.
MEPCO handles net metering for Sahiwal and surrounding districts. Surplus export is credited at approximately Rs. 11 per unit under NEPRA’s net billing framework. Self-consumed solar saves the full retail rate. For agricultural connections, net metering eligibility depends on the connection type. For the complete MEPCO application process, see our MEPCO net metering guide.
Solar Citizen serves Sahiwal with Tier-1 panels, free professional installation, and SOL AI monitoring included with every system. We have experience with both residential rooftop installations and agricultural solar pump systems. Our engineering team designs tubewell systems matched to pump specifications, water table depth, and seasonal irrigation requirements.
We handle everything from site survey to MEPCO net metering approval.

Sahiwal is the historic centre of central Punjab’s cotton belt and a major sugarcane producer — agriculture defines the local economy and shapes solar demand. Climate is hot but slightly more humid than Bahawalpur because of upstream Ravi influence and intensive irrigation. Summer ambients reach 44-47°C in June-July; panel surface temperatures hit 62-69°C. Less extreme than Cholistan but still warm enough that N-type panels are the right choice. Annual generation in Sahiwal averages 1,590-1,650 kWh/kWp — strong, with a milder seasonality than the desert south because monsoon cloud cover (July-August) trims peak generation 8-12% for a 6-week window. Dust accumulation is high during October-November cotton harvest — airborne lint and chaff coat panels and require an unscheduled cleaning. Solar Citizen builds this into the maintenance plan for any Sahiwal install above 10 kW.
Sahiwal falls under MEPCO’s Sahiwal Circle, with sub-divisions covering Sahiwal city, Chichawatni, and Pakpattan-edge areas. Net metering clearance currently runs 28-40 days from filing to bidirectional meter — comparable to Bahawalpur. Sahiwal-specific paperwork wrinkle: agricultural tubewell meters fall under MEPCO’s agri tariff (currently subsidised) and have to be filed separately from residential. If you’re solarising a tubewell on the same property as your home, expect two parallel applications. Solar Citizen handles both. For sugarcane mill operators in Chichawatni area, MEPCO’s industrial-load process applies — different application form, longer clearance (45-60 days), and a load-flow study from a NEPRA-licensed engineer.
Sahiwal solar configurations split sharply along urban-rural lines:
Sahiwal city, 5-10 marla homes (Farid Town, Liaquat Park, Officer’s Colony): Bills PKR 16,000-32,000/month summer. 3-5 kW on-grid is the typical configuration. ROI 3.5-4 years.
1 kanal city plots (College Road, GT Road frontages): Bills PKR 30,000-55,000/month. 7-10 kW hybrid + 6-8 kWh battery. ROI 3-3.5 years.
Agri-residential properties (Chichawatni, Mian Channu road farms): Combined residential + tubewell load is the dominant pattern. A typical setup: 5-7 kW residential array + 10-15 kW for one or two tubewells = 15-22 kW combined. Cotton-farming households benefit further because cotton ginning (Oct-Dec) draws extra load, and net metering credits from summer over-generation offset the autumn ginning bill.
Sugarcane mill peripheral homes (Chichawatni mill area): Often connected to the mill’s industrial grid — solar net metering rules differ. Confirm meter classification before sizing.
For Sahiwal we maintain a roster of agricultural-specialist installers who understand both rooftop and tubewell-pump solar — these are different engineering problems and a single team that does both well is rare.
Will cotton lint damage my panels at harvest time?
No — but it cuts generation 12-18% if left uncleaned. Cotton lint settles in a film that’s harder to wash off than ordinary dust. After harvest we recommend an unscheduled cleaning. Sugarcane bagasse during ginning season is similar.
Can my tubewell run on solar all day?
Yes. A 7.5 HP tubewell needs 5-7 kW peak solar capacity. With midday irradiance peaking at 850-950 W/m² in Sahiwal, a sized array runs the pump comfortably from 9 AM to 4 PM without battery. For evening operation, add 5-10 kWh of battery.
What’s the savings on diesel-replacement for irrigation?
A diesel-powered 7.5 HP tubewell burns roughly 4-5 litres/hour. At current diesel prices, that’s PKR 1,100-1,400/hour. Replacing 6 hours of daily pumping with solar saves PKR 6,500-8,500/day during the cotton or sugarcane growing season. See our solar tubewell pricing breakdown for full math.
How does MEPCO handle dual meters (home + tubewell)?
Separate net metering applications. Different tariffs. Different timelines. Solar Citizen files both in parallel so you don’t lose 4-6 weeks running them sequentially.
