50 kW Solar Plant Cost — Industrial Rooftop Solar Pricing
A 50 kW solar plant generates roughly 80,000 units a year — about 215 to 225 units a day — at an indicative installed cost of ₹21,00,000 to ₹26,50,000. This is industrial territory: single-shift manufacturing units, large hotels, hospital campuses and warehouses with refrigeration.

At 50 kW the project has three engineering phases that a smaller job does not: a structural assessment that may require reinforcement, a load and protection study of the existing electrical infrastructure, and a commissioning programme that produces measured results rather than a functional confirmation. Skipping any of them is how a plant ends up underperforming with no baseline to argue from.
Specification
50 kW solar system — cost, output and requirements
Every figure below is modelled for a 50 kW array in Jaipur-region conditions — clean, unshaded and correctly designed. They are planning numbers for this capacity, not a quotation.
| System capacity | 50 kW |
|---|---|
| Indicative installed cost | ₹21,00,000 – ₹26,50,000 |
| PM Surya Ghar subsidy | Not applicable — the scheme covers residential connections only |
| Tax treatment | Accelerated depreciation available to profit-making entities |
| Daily generation | 215 to 225 units on an average day |
| Annual generation | About 80,000 units |
| Roof area required | About 3,600 sq ft, shade-free |
| Solar panels | 90 to 92 modules at present-day panel wattage |
| Indicative annual saving | About ₹7,20,000 |
| Simple payback | 3 to 4 years |
Pricing is an indicative installed-cost band, not a quotation. Roof type, structure, mounting height, cable run length and module availability all move the figure, and a firm price is issued only after a site survey. Generation assumes roughly 1,600 kWh per kWp per year; savings assume the tariff stated on this page. Subsidy figures follow PM Surya Ghar as currently notified — verify current rates at pmsuryaghar.gov.in.
In practice
What a 50 kW system actually powers
Capacity is easy to quote and hard to picture. At 215 to 225 units a day, this is what a 50 kW array covers in a real building.
- A single-shift manufacturing unit
- A large hotel or resort property
- A hospital or institutional campus building
- A warehouse with refrigeration and handling equipment
Across Rajasthan
What a 50 kW system generates in your city
The same 50 kW array does not produce the same number of units everywhere in Rajasthan. Between Southern Rajasthan and Western Rajasthan the gap is about 8,500 units a year — roughly 11% — which is worth knowing before you compare two quotes written for two different districts.
| Region | Specific yield | 50 kW annual generation | Service areas |
|---|---|---|---|
| Western Rajasthan | 1,740 kWh/kWp | 87,000 units | Jodhpur, Bikaner |
| Shekhawati & eastern Rajasthan | 1,640 kWh/kWp | 82,000 units | Sikar, Neem Ka Thana, Alwar, Ajmer |
| Jaipur region | 1,600 kWh/kWp | 80,000 units | Jaipur, Chomu, Govindgarh, Shahpura |
| Southern Rajasthan | 1,570 kWh/kWp | 78,500 units | Udaipur, Kota |
Gross generation at the regional specific yield, before system and soiling losses — the same convention as the 50 kW figures above, and the same yield table the solar calculator uses. A real site derates this for shading, dust, tilt and orientation, all of which are measured during the free site survey. Regional yields are long-run averages; any single year varies with monsoon cover.
Structural assessment comes before layout
Industrial shed roofs vary enormously in quality. Purlin spacing, section capacity, sheet condition and existing loads all decide what an array can weigh and where it can sit. We survey the structure before drawing a layout, not after.
Where a roof will not carry a ballasted array, the answer is elevation, reinforcement, or a ground-mounted plant on adjacent land. On a site with spare land the ground-mounted option is often better engineering anyway: optimum tilt, easy cleaning access and no structural compromise for twenty-five years.
The economics for an industrial consumer
At an industrial tariff around ₹9 a unit with strong self-consumption, 80,000 units a year is worth roughly ₹7,20,000. Against an installed cost of ₹21 to ₹26.5 lakh, that is a simple payback of three to four years before any tax treatment.
Accelerated depreciation improves the post-tax picture further for a profit-making entity. We provide the generation model and the cost; your finance team should run the depreciation and cash-flow treatment on top of it, because that calculation depends on your tax position rather than on the plant.
Tie-in and production continuity
Roof installation happens while you operate normally. The genuine interruption is the electrical tie-in, which needs a planned outage. We pre-fabricate and pre-test as much as possible so that outage is measured in hours, happens once, and lands inside a shutdown window you have already planned.
Commissioning then produces the documentation that makes the plant maintainable: as-built drawings, string test results, insulation resistance and earth continuity records, inverter configuration records, the O&M manual and a measured performance baseline.
No obligation, no cost

50 kW solar system — frequently asked questions
What is the cost of a 50kW solar plant?
Indicatively ₹21,00,000 to ₹26,50,000 installed in Rajasthan. Where a project falls within that band depends on roof structure and any reinforcement needed, mounting type, cable run lengths, the condition of the existing LT infrastructure and whether the site needs a ground-mounted rather than rooftop solution.
What is the payback period on a 50kW industrial solar plant?
Typically three to four years at an industrial tariff around ₹9 a unit with strong daytime self-consumption, before accounting for accelerated depreciation — which improves the post-tax position further for a profit-making entity. The variables that move payback most are your shift pattern, your tariff category and how much generation you self-consume rather than export.
Will installation disrupt my factory's production?
Roof installation proceeds while you run normally. The only real interruption is the electrical tie-in, which needs a planned outage of a few hours, scheduled into a shutdown window you have already planned. We pre-fabricate and pre-test so that window stays short and is needed once rather than repeatedly.
Can my factory shed roof take a 50kW array?
That is a structural question we answer with a survey before quoting a layout — purlin spacing, section capacity, sheet condition and existing loads all decide it. Where the shed will not carry a ballasted array we design elevation or reinforcement into the project; where the site has spare land, a ground-mounted plant is often the better engineering answer anyway.
