Estimate rooftop-solar ROI with current official subsidy, generation, self-consumption, financing, and DISCOM rules.
Start here
Solar economics depend on usable roof area, local generation, installation quality, tariff structure, subsidy eligibility, and net-metering rules. A sales estimate is not a substitute for a site-specific proposal.
Use the ROI guide as an initial model, then verify current scheme and utility requirements before signing a contract.

Compare rooftop-solar quotes by exact modules, inverter, structure, electrical scope, approvals, generation assumptions, warranties and payment milestones—not ₹/kW alone.
For PM Surya Ghar, use the official portal and your DISCOM workflow, verify consumer details and current eligibility, choose the permitted vendor process, complete inspection and metering steps, and track subsidy only through official status.
Calculate rooftop-solar ROI in India with itemised cost, realistic generation, self-use, export rules, financing and verified subsidy eligibility.
For a rented home, do not install permanent rooftop or electrical solar equipment without written owner and building approval. Decide first who owns the system, who receives the bill benefit, and who pays for removal or roof damage.
Solar earthing and surge-protection checklist for homeowners: verify design, labels, commissioning records and safe inspection points without DIY live electrical work.
Rooftop solar maintenance schedule based on generation trends, safe inspection, condition-based cleaning and qualified electrical checks—not arbitrary calendar cleaning.
Solar loan vs cash purchase: compare finance cost, conservative bill savings, emergency liquidity and verified subsidy before choosing how to pay.
Roof leaking after solar installation? Protect safety, preserve evidence, map the leak to mounting work, obtain a cause report, and document responsibility before repair.
Mono PERC vs TOPCon solar panels: compare exact efficiency, temperature coefficient, module size, warranties, installed ₹/W and roof constraints instead of labels.
Solar inverter undersizing vs oversizing: compare DC/AC ratio, clipping, string voltage/current, MPPT layout and annual energy—not one universal sizing rule.
Understand solar product, performance, inverter and workmanship warranties in India and build a claim with serials, data and contract terms.
Recover a PM Surya Ghar application stuck at the DISCOM by confirming the exact workflow stage, consumer details, missing evidence, portal record, ticket, owner, and escalation route.
When solar generation is below expectation, compare actual weather-normalised production with the design estimate and meter data before blaming modules. Check inverter logs, grid outages, clipping, shade, soiling, string mismatch, tripped protection, meter direction, export curtailment and downtime. Preserve screenshots and interval data for the installer or warranty claim.
For how to verify an approved solar vendor before paying, verify the business and official scheme status where applicable, site-survey assumptions, module and inverter model numbers, structure and electrical scope, generation estimate, warranties, approvals, milestones, exclusions, and service responsibility. Pay against verifiable milestones—not a promise of subsidy, savings, or “lifetime maintenance.”
For solar net meter application delayed, identify the exact stage—application validation, feasibility, vendor installation, inspection, meter, commissioning, bank validation, or subsidy release—and obtain the missing action and owner in writing. Keep portal screenshots, DISCOM ticket, consumer number, installation documents, inspection result, and bank verification together.
Size a solar backup battery from essential-load watts, backup hours, inverter efficiency, usable depth of discharge, surge and ageing. Do not equate battery nameplate kWh with usable AC energy.
Solar-subsidy rejection usually traces to applicant, connection, vendor, equipment, inspection or bank-data mismatch. Use the portal status and scheme version—not installer guesses.
