SolarLogix Powers Laxminarayan Food Products with 258kW Solar Capacity in Purulia
SolarLogix, an Authorised EPC Channel Partner of TATA Power Solar, has completed a 258kW solar installation at Laxminarayan Food Products, a flour mill and food processing unit in Purulia, West Bengal — marking the first manufacturing unit in the district to adopt solar energy at this scale. For a district where industrial solar adoption has been limited, this project gives Purulia’s manufacturing sector a concrete, documented reference point for what solar can deliver.
Why Flour Mills Are a Strong Solar Fit
Flour milling runs a motor-heavy, largely daytime-weighted load — grinding, sifting, and packaging equipment drawing continuous power through operating hours. That daytime concentration is exactly what makes rooftop solar effective for a facility like this: generation lines up closely with when the mill’s machinery is actually running, driving strong self-consumption rather than surplus export.
Laxminarayan Food Products’ move mirrors a pattern SolarLogix has seen across West Bengal’s food-processing and milling sector more broadly — energy-intensive facilities recognising that a correctly sized rooftop system pays for itself well within its operational lifetime.

The Installation
The 258kW system was installed on Laxminarayan Food Products’ GI sheet rooftop, generating an average of 918.48 units of solar power daily. GI sheet structures are common across Purulia’s industrial units, and building on this roof type required mounting engineered specifically for sheet-roof loads — balancing structural longevity with efficient use of available rooftop space.
As an Authorized EPC Channel Partner of TATA Power Solar, SolarLogix managed the project end-to-end, from system design through installation, positioning Laxminarayan Food Products as the first reference site for manufacturing-scale solar adoption in the district.
A Good Day of Solar: What Peak Generation Looks Like
Live plant monitoring data gives a clear picture of what the system delivers on a strong generation day. On 7th June 2026, the plant generated 1,062.70 kWh — well above its 918.48-unit daily average — with the plant graph for that week showing a clean, consistent generation pattern across surrounding days (719.00 kWh, 526.40 kWh, 521.80 kWh, 825.30 kWh) before dipping on 9th June to 113.90 kWh, likely due to cloud cover, and recovering to 581.60 kWh the following day.
This kind of week-to-week variation is normal for any solar installation and reflects real irradiance conditions rather than a system issue — the plant’s CUF (Capacity Utilization Factor) tracked between roughly 8.5% and 10% on AC and DC capacity through this period, consistent with expected performance for a system of this size. The 7th June peak demonstrates the upside built into the system: on strong-irradiance days, Laxminarayan Food Products draws even less from the grid than its average-day numbers suggest.
Financial Impact
The numbers make a clear case for the investment:
- Annual savings: ₹28,49,584.20 — a substantial offset against one of the facility’s largest recurring operating costs
- Payback period: 3.51 years — meaning the system pays for itself in well under four years, with the remaining operational lifetime delivering savings directly to the bottom line
- ROI: 28.51% — a return well above what most facilities could expect from parking the same capital elsewhere
For a flour mill running consistent daytime operating hours, this kind of fast payback reflects how well the facility’s actual consumption pattern lines up with solar generation — a key reason milling and food-processing units see some of the strongest returns among West Bengal’s industrial solar installations.
Environmental Impact
Beyond the financial case, the installation delivers a substantial sustainability footprint:
| Metric | Value |
|---|---|
| CO2 offset | 5,351.49 metric tons/year |
| Equivalent forest area | 6,282.51 acres/year |
| Coal burn avoided | 2,654.02 metric tons/year |
| Equivalent trees planted | 88,561 trees |
| Petrol consumption avoided | 22,82,494.81 liters/year |
| Equivalent distance driven | 2,10,42,679 km |
These figures place Laxminarayan Food Products at the forefront of sustainable manufacturing practice in Purulia — a positioning that carries increasing weight as food-processing supply chains and buyers place more scrutiny on the environmental footprint of their manufacturing partners.
What This Means for Other Manufacturers in Purulia
Laxminarayan Food Products’ results offer a useful reference point for any manufacturing or food-processing unit in the district evaluating solar:
- Daytime-weighted loads maximize solar value. Facilities like flour mills, which run their heaviest equipment during operating hours, see especially strong self-consumption and fast payback compared to loads that run heavily outside daylight hours.
- GI sheet rooftops can support large-capacity systems. A 258kW installation of this scale demonstrates that GI sheet structures, common across Purulia’s industrial units, can support significant solar capacity with the right mounting engineering.
- Being first in a district carries real advantage. As the first manufacturing unit in Purulia to adopt solar at this scale, Laxminarayan Food Products is positioned as a reference site for the district’s manufacturing sector — an advantage worth factoring in for any facility considering an early move.
Getting Started
Every manufacturing facility has a different load profile, roof structure, and grid connection — SolarLogix’s assessment process for facilities like Laxminarayan Food Products typically includes:
- Reviewing 12 months of billing data to map operating-hours load against time-of-day consumption
- Structural assessment of the rooftop (GI sheet or otherwise) for mounting capacity
- System sizing based on actual load, not just available rooftop area
- Financial modeling for ROI, payback period, and financing options
- End-to-end EPC delivery as an Authorized Channel Partner of TATA Power Solar

Frequently Asked Questions
Why is a flour mill particularly well suited to solar power? Flour mills run motor-heavy grinding, sifting, and packaging equipment concentrated during daytime operating hours, which lines up closely with solar generation — driving high self-consumption and faster payback compared to loads that run heavily outside daylight hours.
How was the 258kW system sized for Laxminarayan Food Products? Sizing was based on the facility’s actual daytime operating load rather than available rooftop area alone, ensuring the system’s generation profile matches the mill’s consumption pattern.
What was the payback period for this installation? The Laxminarayan Food Products system has a payback period of 3.51 years, with an ROI of 28.51%.
How much does solar generation vary day to day for a system like this? Live monitoring data for this plant shows day-to-day generation ranging from as low as 113.90 kWh on a cloud-affected day to a peak of 1,062.70 kWh on a strong-irradiance day, against an 918.48 kWh daily average — normal variation for any solar installation based on weather conditions.
Who executed the Laxminarayan Food Products installation? SolarLogix, an Authorized EPC Channel Partner of TATA Power Solar, managed the project end-to-end from design through installation.
