Solar Installation & Solar EPC Company in Jaipur, Rajasthan

Judge a solar company in Jaipur on four things rather than on price per watt: whether they survey the roof and read twelve months of your bills before quoting a capacity; whether they file the JVVNL net-metering application and the PM Surya Ghar subsidy claim for you; whether the equipment is ALMM-listed and BIS-certified as the scheme requires; and whether commissioning produces measured test results and documentation rather than a switch-on. Dvaitam does all four as standard, under one accountable scope from design to handover.

Indicatively ₹55,000 to ₹85,000 per kW for residential systems, falling per kilowatt as capacity rises. A 3 kW system runs about ₹1.7–2.15 lakh before the ₹78,000 PM Surya Ghar subsidy, netting out near ₹1 lakh. A 5 kW system runs about ₹2.7–3.4 lakh before subsidy. Commercial and industrial plants price considerably lower per kW at scale. Every figure is confirmed after a site survey, because roof type, structure and cable runs genuinely move it.

Up to ₹78,000 under PM Surya Ghar: Muft Bijli Yojana. The scheme pays ₹30,000 per kW for the first 2 kW and ₹18,000 for the third, capping at ₹78,000 for any residential system of 3 kW or above. It applies to domestic connections only — commercial and industrial consumers are not eligible, though their case usually stands on displacing units at a higher tariff.

Four conditions must be met together: you are an Indian citizen, you own the house where the system is installed, the household has a valid electricity connection with JVVNL, AVVNL or JdVVNL, and you have not already claimed another central solar subsidy on that connection. The scheme covers domestic connections only — a shop, guest house or factory does not qualify even if a family lives above it.

About 1,550 to 1,650 units per installed kilowatt per year for a clean, unshaded, correctly designed array. That means roughly 4,800 units a year from a 3 kW system and 8,000 from a 5 kW system. Western Rajasthan — Jodhpur and Bikaner — generates 8 to 9% more; Udaipur and Kota slightly less. Dust matters: an uncleaned array in Jaipur can lose 8 to 15% of its output.

The physical installation of a residential system takes two to four days. The full timeline from order to a working net meter is normally six to ten weeks, and nearly all of that is DISCOM process time — feasibility approval, net-meter sanction and inspection scheduling — rather than work on your roof. Commercial and industrial projects typically run eight to twelve weeks or longer.

A correctly sized system with net metering can offset the large majority of your annual consumption, and bills falling by 80–95% are common where the capacity matches the load. It is never 100%: fixed charges, meter rent and any consumption beyond what the system generates remain. We model your actual bill and show what the residual looks like rather than quoting a headline percentage.

Work from annual consumption, which is printed on your bill, not from roof area. Each installed kilowatt generates roughly 1,600 units a year in Jaipur, so annual units divided by 1,600 gives the capacity that would fully offset your usage. A home using 5,000 units a year needs about 3 kW; one using 8,000 needs about 5 kW. Sanctioned load and available shade-free roof then confirm whether that capacity is achievable.

Roughly 70 to 80 sq ft per kilowatt, including the row spacing needed to avoid winter self-shading and enough walkway space to clean the modules. So about 220 sq ft for 3 kW, 350 sq ft for 5 kW and 700 sq ft for 10 kW. Only genuinely shade-free area counts, which on most Jaipur plots is less than the terrace looks once the mumty, water tanks and neighbouring construction are excluded.

A net meter records import and export separately, and you are billed on the net position. The process runs through your DISCOM — JVVNL, AVVNL or JdVVNL depending on location — as a feasibility application, sanctioned-load verification, installation by a registered vendor, net-meter application, inspection and commissioning certificate. Permitted capacity is tied to your sanctioned load, which is the most common reason an application is returned.

JVVNL covers Jaipur, Chomu, Shahpura, Alwar, Kota, Dausa, Bharatpur and Tonk. AVVNL covers Ajmer, Kishangarh, Sikar, Neem Ka Thana, Jhunjhunu, Bhilwara, Nagaur and Udaipur. JdVVNL covers Jodhpur, Bikaner, Barmer, Jaisalmer, Pali, Churu, Ganganagar and Hanumangarh. Each runs its own process and forms — filing under the wrong one costs weeks. We confirm it from your bill before anything is submitted.

Not if it is a standard grid-tied system. Grid-tied inverters are required by regulation to shut down when the grid fails, for the safety of anyone working on the line. If you need generation during outages — which matters more in rural and semi-urban areas than in central Jaipur — the answer is a hybrid system with battery storage covering essential circuits. It costs meaningfully more, and we will tell you honestly whether your supply justifies it.

Cleaning is the main thing, and the interval depends on where you are: every two to four weeks in Jaipur through the dry months, more often in quarry, agricultural or desert belts, and promptly after any dust storm. Annually, connections should be thermographically scanned under load, insulation resistance and earth continuity retested against the commissioning baseline, and the inverter serviced at manufacturer intervals.

For a residential system with the PM Surya Ghar subsidy, three to five years is normal in Rajasthan. For a commercial or industrial system with strong daytime self-consumption, three to four and a half years is typical before accelerated depreciation is taken into account. We model payback at a flat tariff — a projection that only works if electricity prices rise is a sales device, not an analysis.

Usually yes, and often more so than residential. Commercial tariffs run well above domestic rates, so each displaced unit is worth more, business consumption generally lines up with generation hours, and accelerated depreciation improves the post-tax position for a profit-making entity. Together those typically beat the ₹78,000 residential subsidy within the first two years.

Structural survey and any reinforcement design, load flow and protection coordination against your existing installation, detailed design with single line diagrams and cable schedules, procurement against specification, construction to method statements, a tie-in planned around your production shutdown window, and commissioning with measured results, as-built drawings, an O&M pack and a performance baseline.

Yes, and it is common — but only after the structure is assessed. Purlin spacing, section capacity, sheet condition and existing loads decide what an array can weigh and where it can sit. We survey before drawing a layout and design reinforcement where it is needed. Where a site has spare land, a ground-mounted plant is often the better engineering answer, and we will say so.

ALMM-listed modules from established manufacturers — Adani Solar, Waaree, Tata Power Solar, Vikram Solar and RenewSys among them — and inverters from brands including Sungrow, Growatt, Solis, SMA and Fronius. Selection follows the engineering: temperature coefficient and degradation for modules, and MPPT configuration, loading ratio and in-state service support for inverters.

Yes, across Rajasthan — Chomu, Govindgarh, Shahpura, Neem Ka Thana, Sikar, Alwar and its industrial belt at Bhiwadi and Neemrana, Ajmer and Kishangarh, Jodhpur, Kota, Udaipur and Bikaner. Each falls under a different distribution company with its own net-metering process, and we file under the correct one. Where a site sits outside our service area we say so at enquiry stage rather than stretching to cover it.

Your last electricity bill — ideally twelve months of them — and a photo of the roof. That is enough for an indicative capacity, generation estimate and subsidy position. A firm price follows a free site survey, because roof type, structure, mounting height and cable run length genuinely move the number and cannot be guessed from a photograph.
