Daily Power Generation, Monthly Savings, and Payback Timeline
Basti district enjoys favorable solar irradiance, receiving over 300 sunny days annually. A professionally oriented south-facing 3kW solar system in Basti generates between 12 and 14 units (kWh) of electricity daily under standard climatic conditions, producing roughly 360 to 420 units every month and 4,300 to 4,800 units per year.
Generation levels vary across seasonal weather patterns in eastern Uttar Pradesh. Peak generation occurs during the clear summer months of March through June, averaging 14 to 16 units daily. During monsoon cloud cover and dense winter fog in December and January, daily output averages 7 to 9 units. Because the system operates on annual net metering, surplus units produced during sunny months roll forward to offset power consumed during low-generation seasons.
| Metric | Daily Output | Monthly Output | Annual Output | Estimated Financial Value (@ ₹7.00/unit) |
|---|---|---|---|---|
| Peak Summer Generation (Mar–Jun) | 14 – 16 Units | 420 – 480 Units | — | ₹2,940 – ₹3,360 / month |
| Moderate Season (Sep–Nov, Feb) | 12 – 14 Units | 360 – 420 Units | — | ₹2,520 – ₹2,940 / month |
| Winter & Monsoon (Jul–Aug, Dec–Jan) | 7 – 10 Units | 210 – 300 Units | — | ₹1,470 – ₹2,100 / month |
| Yearly Average Total | ~12.5 Units/day | ~375 Units/month | 4,300 – 4,800 Units | ₹30,000 – ₹33,600 / year |
With domestic electricity tariffs in Uttar Pradesh averaging ₹6.50 to ₹7.50 per unit in the higher residential consumption slabs, an annual generation of 4,500 units saves approximately ₹31,500 every year. Comparing these annual savings against an initial net cost of ₹85,000, homeowners achieve full capital payback in just 2.7 years. After the payback threshold, the plant continues to supply virtually free electricity for the remainder of its 25-year panel performance warranty.
What Appliances Can You Run on a 3kW Solar System?
A 3kW on-grid solar plant delivers ample generation capacity to support the complete power requirements of an active modern family home. Unlike small off-grid inverters that are strictly limited by battery surge limits, an on-grid system operates seamlessly in synchronization with the PuVVNL grid.
