Factories and plants
Daytime load, a sheeted roof and an HT connection. That is work we already do.
A system sized to the plant's daytime load, its case made on the tariff it displaces, by the firm that already does the structure, the HT and LT work and the DISCOM paperwork.

Your estimate, as text
Solar estimate: Factory or plant, bill Rs 3 lakh a month System size: 327 kWp. Assumes 39,216 kWh a month at Rs 7.65 per unit, 4 sun hours a day (1,460 kWh per kWp a year) and 85 sq ft of roof per kWp. Monthly saving: about Rs 2.7 lakh. Assumes 90% of the generation offsets the bill through daytime use and net metering. System cost: Rs 1.3 to 1.7 crore. From the MNRE benchmark cost for rooftop solar, general category states: Rs 50,000 per kW for the first 2 kW and Rs 45,000 per kW after, in force from 13 Feb 2024, with a band of 0.9x to 1.15x. Checked 5 Sep 2026. PM Surya Ghar assistance: none. The scheme covers homes and housing societies; a factory's case rests on the tariff it displaces. Source: MNRE operational guideline for PM Surya Ghar, OM 318/17/2024-GCRT of 7 Jun 2024, checked 5 Sep 2026. Cost after assistance: Rs 1.3 to 1.7 crore. Payback: 4 to 5 years. The cost after assistance divided by a year of the saving. Kept over 25 years: Rs 8.1 crore. The monthly saving over 300 months, before tariff rises and without panel degradation. Tariff as of 5 Sep 2026: TGERC retail supply tariff order FY 2025-26, HT-I(A) industry at 11 kV, energy charge only. This is an estimate from the assumptions above. A roof survey and a written proposal replace it. https://leo-solar.in
How we got this, and your own tariff
How we got this. Tariff Rs 7.65 per unit (HT-I(A) industry at 11 kV, energy charge only, Telangana), 4 units per kWp per day (1,460 a year, a normal south Indian rooftop yield), 85 sq ft of roof per kWp. Benchmark cost Rs 50,000 per kW for the first 2 kW and Rs 45,000 after (MNRE, 13 Feb 2024), with a band of 0.9x to 1.15x. No central assistance for a factory or plant; the case rests on the tariff displaced (MNRE guideline, 7 Jun 2024). Tariff from the TGERC retail supply tariff order FY 2025-26, checked 5 Sep 2026. Daytime use assumed at 90%. This is an estimate; the number that matters comes from a roof survey, in writing.
The record
The firm on record
Approvals, coordination and charging with a distribution utility are routine here rather than an unfamiliar obstacle, because the firm's existing distribution work runs through the same offices.
- 2014Trading since
- 50Qualified staff
- 95Projects delivered
- 11 KVRegistered vendor since 2018
The record of Leo Enterprises, the parent firm, across all of its work; none of these is a solar installation.
The registration
Registered with the utility
Leo Enterprises has been a registered vendor to the Telangana distribution utility for 11 KV installation and distribution since 2018. The registration is held in the parent firm's name; the certificate is shown here once the client has confirmed it in writing.
The engineering
The engineering scope
Factory, warehouse, office, hospital and hotel roofs, sized against the plant's own daytime load and tied into distribution the same firm already builds.
Suited to
- Plants with a large sheeted or RCC roof already carrying the load
- Sites paying an industrial or commercial tariff on a high daytime demand
- Operations that cannot take an unplanned shutdown for the installation
The structural check
Structural assessment of the existing roof before anything is fixed to it. Mounting frames are fabrication and the roof underneath is a structural question. Civil construction is the discipline this firm was founded on in 2014.
HT and LT tie-in
Tie in to the plant's existing LT or HT distribution. The firm is a registered vendor to the Telangana distribution utility for 11 KV installation and distribution, and does HT and LT cable laying, termination and testing. A rooftop tie in is the small end of that work, not a new discipline.
Earthing and lightning protection
Earthing and lightning protection for the array, the inverter and the structure, tested and recorded before the tie-in. DC and AC cabling, combiner and inverter installation.
Shutdown planning
Operations that cannot take an unplanned shutdown for the installation get a planned one: the tie-in is the one step that needs the supply off, and it is booked to a window the plant chooses, with the switching written down before the day.
Net metering sets the rooftop's generation against the bill of the connection it sits on. Open access buys or wheels power under a separate agreement with the DISCOM and the regulator, with its own charges and its own paperwork. A rooftop sized to the plant's own daytime load usually runs on net metering; which route fits your connection is settled at the survey and written into the proposal.
The proposal
The survey packet
What the written proposal contains, and what you hold before anything is ordered.
Step 03, System design and written proposal
Sizing, layout, the mounting arrangement, the electrical scheme and the price, in writing. Nothing is ordered before this is agreed.
- Sizing
- The system against the plant's daytime load and the roof that can carry it.
- Layout
- The array on the roof plan, around the existing plant, walkways and skylights.
- The mounting arrangement
- The structure and the fixings, to the structural check.
- The electrical scheme
- The tie-in point, the protection and the metering, and where each sits.
- The price
- In writing, for the scope above, before anything is ordered.
Start with the survey.
An engineering visit to the roof and the supply, not a sales visit; then the packet above, in writing.
