Your estimate, as text
Solar estimate: Home, bill Rs 2,500 a month System size: 2.5 kWp. Assumes 325 kWh a month at Rs 7.70 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 2,100. Assumes 90% of the generation offsets the bill through daytime use and net metering. System cost: Rs 1.1 to 1.4 lakh. 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: Rs 69,000. Home rule: Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the third, capped at Rs 78,000. 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 41,300 to 71,900. Payback: 2 to 3 years. The cost after assistance divided by a year of the saving. Kept over 25 years: Rs 6.2 lakh. 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, LT-I(B)(ii) domestic, 201 to 300 units a month. 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. Tariff Rs 7.70 per unit (LT-I(B)(ii) domestic, 201 to 300 units a month, 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. PM Surya Ghar assistance Rs 30,000 per kW for the first 2 kW and Rs 18,000 for the third, capped at Rs 78,000 (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.
Rooftop solar for homes, housing societies, factories and public buildings, from the roof survey through to the net meter and the subsidy paperwork.
Illustrative image, not a Leo installation. The plants, the capacity and the states come from the client's project register of September 2026. The capacity counts the 12 plants of 24 whose works order states one, so the real total is higher, and it leaves out plants we were asked to finish rather than build. Leo Enterprises has traded since 2014.
Our services
Houses and housing societies under the central subsidy, factory and plant roofs on the tariff alone, and public buildings to the department specification.
Talk to an expertHomes & societies
Rooftop systems for houses and housing societies, sized against your own bill, with the PM Surya Ghar application filed for you.
Businesses & industry
Factory, warehouse, office, hospital and hotel roofs, sized against the daytime load and tied into the distribution this firm already builds.
Public sector
Institutes, campuses and offices, placed through CPWD, MES and GeM and built to the department specification and inspection.
After handover
We hold maintenance contracts on 5 of the plants on our register, from one to three years: cleaning, inspection, inverter and earthing checks, and the paperwork with the utility.
Every project
The structure, the electrical work and the utility paperwork are three jobs. This firm does all three, so the roof, the tie in and the approvals do not sit with three different contractors.
System sizing, structural checks and yield modelling.
Paperwork and utility liaison handled end to end.
Safe, precise installation and grid connection.
Cleaning, inspection and the utility paperwork, under contract on the plants we maintain.
Why Leo Solar
The mounting frames are fabrication, the roof under them is a structural question and the tie in is electrical work. This firm has done all three since 2014, and has been a registered vendor to the Telangana distribution utility for 11 KV work since 2018.
On the register
13 plants handed over, and the same engineers on the maintenance afterwards.
See the projectsMounting frames are fabrication and the roof underneath is a structural question. Civil construction is the discipline this firm was founded on in 2014.
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.
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.
Sizing, layout, the mounting arrangement, the electrical scheme and the price, in writing. Nothing is ordered before this is agreed.
Most of the register is work placed through CPWD, MES, GeM and DGD, in 10 states, built to the department specification and passed by its own inspection.
5 of the plants on the register are under a maintenance contract with us, from one to three years, run by the same service engineers.
How it works
Two of them are the ones most installers leave off the diagram: the structural check before anything is fixed to the roof, and who files the paperwork with the utility.
A conversation about what you are paying now, what you consume during daylight, and what the roof is. Most of what decides whether rooftop solar is worth it is in the first two.
The roof is inspected for structure, orientation, shading and access, along with the existing electrical supply and where the system would tie in. This is an engineering visit, not a sales visit.
Sizing, layout, the mounting arrangement, the electrical scheme and the price, in writing. Nothing is ordered before this is agreed.
The application to the distribution utility, and for residential systems the central subsidy application, are prepared and submitted. This is the step that most often decides how long the whole job takes.
Mounting structures fabricated and installed to the survey, fixed so that the roof's waterproofing survives the installation.
Panels, inverter, DC and AC cabling, protection, earthing and lightning protection, and the tie in to your existing distribution.
The installation is tested, then charged and commissioned with the utility's meter in place. You are shown what the system is doing and how to read it.
Documentation handed over, with maintenance support afterwards through the same service engineers who cover the rest of the firm's work.
How long it takes
The application to the distribution utility, and for residential systems the central subsidy application, are prepared and submitted. This is the step that most often decides how long the whole job takes.
Benefits of solar
Solar cuts what you pay today, protects you from what tariffs do tomorrow, and shrinks your footprint for decades.

Financial return
Generate your own power during the day and export the surplus. Most systems recover their cost within a few years, then keep saving.
