Offices and commercial buildings in Lucknow, Kanpur, Raebareli, and Barabanki pay UPPCL commercial tariffs between Rs 7 and Rs 9 per unit in 2026. With air conditioning, computers, lighting, and server infrastructure running eight to twelve hours a day, a medium-sized office typically spends Rs 20,000 to Rs 1,50,000 on electricity every month. A correctly sized rooftop solar system can cover 60 to 80 percent of that load, and the 40 percent accelerated depreciation benefit means most office buildings recover their investment in four to five years.
This guide covers system sizing, realistic savings numbers, UPPCL net metering, tax benefits, and the practical checks every office owner or facilities manager should make before signing a solar contract in UP.
Why Offices Are Among the Best Solar Candidates in UP
Daytime Load Alignment
Office electricity consumption peaks between 9 AM and 6 PM, which is almost exactly when a rooftop solar system generates its peak output. Unlike homes where residents leave for work and solar generation goes partly unused, an occupied office building absorbs nearly every unit the panels produce in real time. This direct consumption, rather than export to the grid, gives you the full commercial tariff saving of Rs 7 to Rs 9 per unit on every solar unit generated.
High Commercial Tariffs Make the Numbers Work
UPPCL charges commercial and non-domestic consumers Rs 7 to Rs 9 per unit in 2026, compared to Rs 5 to Rs 7 for domestic connections. Every solar unit an office consumes avoids the higher commercial rate. A 20 kW system generating 2,400 units per month saves Rs 16,800 to Rs 21,600 every month, which is a payback trajectory well under five years for most office installations in Lucknow and surrounding districts.
Flat Rooftops Built for Solar
Most commercial office buildings across Lucknow, Kanpur, and Raebareli have flat RCC rooftops that are structurally sound and require only standard mounting frames. The available terrace area on a typical three-to-five-storey building comfortably accommodates 20 to 100 kW of solar capacity, which is enough to cover the majority of office electricity consumption for most building sizes.
System Sizing and Costs for Office Buildings in UP
Sizing Your System to Your Consumption
The simplest starting point is your average monthly UPPCL bill. Divide the monthly units consumed by 120 to get a rough system size in kW. A 5 kW system generates roughly 600 units per month under Lucknow's solar conditions, a 10 kW system generates around 1,200 units, and a 20 kW system generates approximately 2,400 units.
Typical sizing examples for UP office buildings:
- Small CA firm or consultant office using 700 units/month: 6 kW system, covers 85 to 100 percent of daytime consumption.
- Medium office with 20 workstations, two AC units, using 2,000 units/month: 17 to 18 kW system, covers 70 to 80 percent of total consumption.
- Large corporate or multi-floor office using 5,000 units/month: 40 to 45 kW system, covers 60 to 70 percent, with the remainder drawn from the UPPCL grid outside peak solar hours.
Always check your UPPCL sanctioned load before finalising a system size. Net metering rules in UP do not allow solar capacity to exceed your sanctioned load.
Installation Costs in 2026
Commercial solar installation in UP costs Rs 55,000 to Rs 70,000 per kW in 2026, depending on panel brand and inverter quality. A 20 kW system for a mid-sized office comes to Rs 11 to Rs 14 lakh before tax benefits. Larger systems above 50 kW attract slightly lower per-kW pricing due to economies of scale.
Accelerated Depreciation: The Biggest Financial Lever
The most significant benefit for commercial buyers is the 40 percent accelerated depreciation available under Section 32 of the Income Tax Act. For an office registered as a company or firm, a Rs 12 lakh solar system reduces taxable income by Rs 4.8 lakh in year one alone, generating a direct tax saving of Rs 1.2 lakh at a 25 percent tax rate. Combined with monthly bill savings, the effective payback period for a commercial office in Lucknow or Kanpur typically falls between three and a half and five years.
PM Surya Ghar Subsidy and Commercial Offices
The PM Surya Ghar Muft Bijli Yojana central subsidy of up to Rs 78,000 applies only to residential consumers on domestic tariff connections. Office buildings on commercial or LMV-2 connections are not eligible for this subsidy. However, the accelerated depreciation benefit available to commercial entities typically delivers a larger financial saving than the residential subsidy for systems above 10 kW.

UPPCL Net Metering for Commercial Offices
How Net Metering Works in Practice
A well-designed solar system for an office that operates six days a week will export very little to the grid, since the building's loads consume most of the generation during working hours. Net metering matters most on Sundays, public holidays, and during peak generation months when the office is closed but the panels are still producing.
UPPCL credits exported units against future consumption at the applicable rate. Commercial consumers in UP receive a carry-forward credit for three to twelve months depending on their DISCOM. Any remaining credit at the end of the settlement year is settled at the approved feed-in tariff.
Net Metering Application Steps for Offices in Lucknow and Kanpur
For offices in Lucknow under LESCO (Lucknow Electricity Supply Company), or in Kanpur under KESCO, the net metering process involves:
- Submit a net metering application to your DISCOM with load sanction details and a proposed system size.
- Receive feasibility approval based on your sanctioned load and local transformer capacity.
- Install the solar system using a UPPCL-empanelled or MNRE-registered installer.
- Apply for a bidirectional meter. UPPCL installs the meter at no cost to the consumer.
- Commission the system after a UPPCL inspection, at which point net metering becomes active and your bill starts showing solar generation.
The total timeline from application to commissioning is typically four to eight weeks for commercial connections, though it can be longer in congested urban areas where transformer capacity is limited.
Practical Checks Before Installing Solar on Your Office
Sanctioned Load and Load Enhancement
Many older office buildings in Lucknow, Barabanki, and Raebareli have sanctioned loads of 10 to 20 kW even when actual consumption is significantly higher. If your sanctioned load is lower than the system size you need, you must apply for a load enhancement with UPPCL before your solar application is approved. Budget an additional Rs 30,000 to Rs 80,000 and four to eight extra weeks for the enhancement process.
Roof Ownership and NOC Requirements
If your office occupies a floor in a commercial complex you do not own, such as buildings in Hazratganj, Gomti Nagar, or the Kanpur city center, you will need a written no-objection certificate from the building owner before UPPCL approves net metering on your connection. This is one of the most common delays in commercial solar projects in UP, so confirm roof access and ownership early in the process.
Panel Soiling in UP Summers
Lucknow and surrounding districts experience heavy dust deposition during April and May, which can reduce panel output by 15 to 25 percent on uncleaned surfaces. For an office building, include panel cleaning in the building's regular maintenance schedule or take an annual maintenance contract with your solar installer. Most commercial installations in UP need cleaning once a fortnight during the dry season and once a month after the monsoon.
Structural Assessment for Older Buildings
Solar panel mounting structures typically add 15 to 20 kilograms per square metre to a rooftop. For most post-2000 RCC office buildings this is well within structural limits, but older buildings in commercial areas of Lucknow and Kanpur may need a structural engineer's sign-off before installation. A reputable installer will include a structural assessment in the site survey, and you should decline any quote that skips this step.
Realistic Savings Numbers for UP Office Buildings
For an office in Lucknow paying Rs 8 per unit on a commercial tariff, a 20 kW system generating 2,400 units per month saves approximately Rs 19,200 per month in energy charges. Against a post-depreciation effective cost of Rs 8 to Rs 9 lakh (after the year-one tax saving), the simple payback period is under four years. Over 25 years, the same system delivers an estimated Rs 60 to Rs 80 lakh in cumulative electricity savings at today's tariffs, before accounting for future tariff increases.
These figures apply to offices in Lucknow, Kanpur, Raebareli, and Barabanki. Offices in smaller district towns with older infrastructure and longer power cuts may see additional savings from reduced generator runtime if they add a battery backup system, though the payback on the battery component is calculated separately.
