Detailed answers about rooftop solar, PM Surya Ghar, PM-KUSUM, state-level support, loans, net metering, installation and long-term savings.
Understand how rooftop solar works, what system size means and which system type may suit your property.
Best suited where the grid is reliable and the goal is primarily electricity-bill savings.
Designed for independent power where grid supply is unavailable or unreliable.
Combines grid connectivity with battery backup and greater energy flexibility.
Solar panels generate DC electricity from sunlight. The inverter converts it into AC electricity for use by your home or business. Depending on the system type, surplus energy can be exported to the grid or stored in batteries.
The recommendation is generally based on your electricity consumption, usable roof area, shading, connected load, local solar conditions, budget and future electricity needs. A site survey helps confirm the practical capacity.
kW indicates the rated capacity of the solar system, while kWh measures the amount of electricity generated or consumed over time. Your monthly electricity bill normally reflects consumption in kWh or units.
Yes, but generation is lower when sunlight is weaker. Solar generation naturally changes with weather, season, shading, temperature and local conditions.
Possibly. The impact depends on how much area is shaded, when shading occurs and the proposed layout. A site survey helps identify the most usable roof area and suitable design.
There is no single best system for every property. On-grid is commonly chosen for savings, off-grid for independence, and hybrid where both backup and grid connectivity are important.
Questions about central financial assistance, eligibility, application process and subsidy credit.
PM Surya Ghar provides central financial assistance for eligible residential rooftop solar installations.
Application, feasibility, installation and inspection typically involve the national portal and the relevant DISCOM.
The actual amount and eligibility depend on the approved scheme rules and installed capacity.
It is a Government of India rooftop-solar programme focused on residential consumers. Eligible households can apply for rooftop solar through the official portal and may receive central financial assistance subject to scheme conditions.
As reflected in current government-linked financing information, commonly referenced central assistance is ₹30,000 for 1 kW, ₹60,000 for 2 kW and up to ₹78,000 for 3 kW or above, subject to current scheme rules and eligibility. Always verify the amount on the official PM Surya Ghar portal before purchase.
The scheme is intended for eligible residential electricity consumers. Final eligibility depends on the scheme guidelines, electricity connection, property/roof rights, DISCOM requirements and other portal conditions.
The consumer generally registers on the official PM Surya Ghar portal, selects the relevant state and DISCOM, completes the required application steps, proceeds with an eligible installation, completes inspection/commissioning formalities and submits the required information for subsidy processing.
No installer should treat government subsidy as automatically guaranteed. Approval depends on eligibility, scheme compliance, portal processing, documentation, installation requirements and verification by the responsible authority.
Rivon can guide customers through the applicable documentation and process where such assistance forms part of the project scope. The final approval and subsidy disbursement remain with the relevant government authority and DISCOM.
Yes, financing options exist for eligible rooftop-solar projects. Some lenders allow the subsidy amount to be credited toward the loan account after it is received. Loan eligibility and subsidy eligibility are separate checks.
Use the official PM Surya Ghar portal and MNRE notifications because subsidy structures, operational procedures and amendments can change over time.
Understand solar pumps, farm solarisation and the key PM-KUSUM components.
Eligible participants can develop decentralised grid-connected renewable power plants under scheme conditions.
Supports eligible standalone solar agricultural pumps.
Covers solarisation of eligible grid-connected agricultural pumps and feeder-related models.
PM-KUSUM is a Government of India scheme designed to promote solar energy in the agriculture sector, reduce dependence on diesel and support decentralised renewable-energy generation.
Component A relates to decentralised grid-connected renewable power plants. Under the scheme framework, eligible projects can include grid-connected solar power plants on suitable land, subject to state implementation and DISCOM arrangements.
Component B focuses on standalone solar-powered agricultural pumps for eligible farmers and beneficiaries.
Component C includes solarisation of eligible grid-connected agricultural pumps and feeder-level solarisation models under the applicable implementation framework.
The official PM-KUSUM portal states that central government subsidy can be up to 30% or 50% of total cost for certain standalone solar-pump and pump-solarisation configurations, depending on the applicable category and location. State contributions, beneficiary share and financing structures can differ.
Under relevant PM-KUSUM configurations, eligible grid-connected solar power plants may sell electricity to the local DISCOM under state-regulated arrangements. Exact tariff and procurement conditions depend on the state and DISCOM.
No. The scheme is implemented through designated state agencies and state-level departments, so application windows, vendor lists, rates, beneficiary contribution and timelines can differ by state.
The official PM-KUSUM portal publishes public information including state-wise vendor lists, rate cards and scheme documents. Always verify the latest state implementation details before applying.
Central schemes may be uniform, but state incentives, DISCOM processes and implementation details can differ.
Central financial assistance follows national scheme guidelines for eligible categories.
Some states or local agencies may offer additional incentives or special programmes.
Feasibility, metering, inspection and grid procedures are handled through the applicable utility.
Central assistance under a national scheme follows central guidelines, but state-level incentives, utility procedures and additional benefits can vary. A consumer should verify both the national scheme and the relevant state/DISCOM requirements.
Check your state renewable-energy agency, electricity DISCOM and official government notifications. Additional state benefits can be introduced, modified, paused or limited by budget and eligibility rules.
Each DISCOM operates within applicable state regulations and local grid procedures. Feasibility approval, documentation, inspection, metering and turnaround times can therefore differ.
Rivon can help identify the relevant central and state-level process based on your location, but any incentive should be confirmed against the latest official state, DISCOM and government notification before finalising the project.
Do not assume residential subsidy automatically applies to commercial or industrial installations. Commercial and industrial projects are generally evaluated under different regulatory, tariff, financing and policy frameworks.
The National Rooftop Solar portal maintains DISCOM information and contact details by state. Your electricity bill also normally identifies the relevant distribution company.
No. Government incentives can change. Use official portals, DISCOM information and current scheme notifications as the source of truth.
Loan eligibility, subsidy adjustment, repayment and lender requirements explained in simple language.
Banks and lenders may finance eligible residential rooftop-solar systems subject to credit and documentation checks.
Some loan structures allow received subsidy to be credited toward the loan account.
Look beyond EMI and compare interest, tenor, margin, processing charges and insurance conditions.
Yes. Several banks and financial institutions offer rooftop-solar financing products, subject to their credit policy, documentation, project eligibility and borrower profile.
Requirements vary by lender but may include identity/address documents, electricity bill, bank details, rooftop rights or property-related proof, vendor quotation, feasibility report and income/credit documents depending on the loan amount.
Some solar-loan products disburse directly to the approved vendor, channel partner or EPC contractor. The exact disbursement process depends on the lender.
Some lenders provide for the received subsidy to be credited toward the solar loan when the borrower provides the required loan details during the subsidy process. Confirm the mechanism with your lender before signing the loan agreement.
Interest rates are lender-specific and can change. They may depend on the loan amount, benchmark lending rate, borrower profile and scheme. Always check the lender’s current published rate rather than relying on an old quotation.
Tenor varies by lender. For example, current SBI PM Surya Ghar loan information lists a maximum tenor of up to 120 months including the moratorium period for eligible products. Other lenders may use different terms.
Credit-score requirements depend on the lender and loan size. Some specific small-ticket solar loan products may have relaxed score requirements, while higher loan amounts may require a minimum score.
Compare both. A lower EMI can simply mean a longer tenor. Review interest rate, total interest, margin contribution, processing fees, insurance, prepayment terms and how subsidy will be handled.
Rivon can provide project-related documents such as quotations and applicable technical information. Final loan sanction, eligibility and lender documentation are controlled by the bank or financial institution.
Learn about export, meter changes, approvals and why your electricity bill may still include charges.
Net metering is a billing mechanism for eligible grid-connected solar consumers under which exported solar electricity is measured and adjusted according to applicable state regulations and DISCOM rules.
Depending on the applicable DISCOM process and metering arrangement, a compatible bidirectional or net meter may be required. The utility determines the applicable metering requirements.
Eligible grid-connected systems may export surplus electricity, subject to the sanctioned capacity, metering arrangement and applicable state/DISCOM regulation.
Solar can reduce energy charges, but fixed charges, minimum charges, taxes, duties, night-time consumption, seasonal variation and the applicable metering framework may still result in a payable bill.
Standard on-grid inverters generally shut down during a grid outage for anti-islanding safety. Backup during outages usually requires a suitable hybrid/off-grid configuration with battery or other approved backup arrangement.
Timelines vary by DISCOM, state, inspection schedule, meter availability and document readiness. Utility approval timelines are outside the installer’s direct control.
Where included in the project scope, Rivon can support the documentation and coordination process. Final approval, meter installation and grid permissions remain with the relevant DISCOM.
Understand roof suitability, project timelines, equipment and what happens after installation.
A site survey helps assess usable roof area, shading, structure, orientation, electrical infrastructure, cable routes, inverter location, access and safety considerations before final design.
The physical installation period depends on project size and site complexity. Utility approval, subsidy processing, meter work and commissioning can take additional time and may involve third parties.
A correctly engineered mounting approach should be selected for the roof type and structural condition. The survey and installation method are important for managing roof integrity and waterproofing concerns.
The inverter is generally placed in a suitable accessible location with appropriate ventilation, protection and proximity to electrical connections. Final placement depends on the site design and manufacturer requirements.
Panels should be kept reasonably clean. Cleaning frequency depends on dust, pollution, rainfall, bird activity and local conditions. Unsafe rooftop access should always be avoided.
Review module product/performance warranties, inverter warranty, battery warranty where applicable, mounting-system terms and installer workmanship/service commitments. Warranty length alone is not enough; exclusions and claim procedures matter too.
Yes, subject to technical feasibility, structural suitability, sanctioned electrical load, roof availability, applicable approvals and project economics. Commercial and industrial system design is usually more customised than residential rooftop solar.
Rivon’s agriculture solutions can include solar-pump and farm-energy requirements subject to site assessment, pump sizing, water source, head, irrigation requirement and applicable scheme/vendor conditions.
Savings, generation, maintenance, warranties and long-term support explained.
Savings depend on system size, solar generation, electricity tariff, consumption pattern, self-consumption, metering arrangement, financing cost and seasonal conditions. A technical and financial estimate is more useful than a generic percentage.
Do not assume a zero bill. Even when solar offsets a large share of energy consumption, fixed charges, taxes, utility rules, night consumption and seasonal variation may still produce a payable amount.
Generation depends on capacity, location, solar irradiation, orientation, temperature, shading, equipment performance, downtime and system losses. It should be estimated for the actual project location rather than treated as a fixed universal number.
Payback depends on project cost, subsidy where applicable, electricity tariff, generation, financing cost and usage pattern. Commercial and residential projects can have very different economics.
Solar can improve a property’s energy profile and reduce operating costs, but any effect on resale or rental value depends on local market conditions and should not be treated as guaranteed.
Check for unusual shading, dirt, inverter alarms, grid outages or equipment issues. If the drop persists, contact the service team so system data and equipment can be reviewed.
Rivon’s support model is designed to continue beyond installation. The exact maintenance, service and warranty scope for a specific project is governed by the accepted quotation, agreement and manufacturer warranty terms.
Yes. Use the Rivon Solar Savings Calculator for an initial estimate, then use a site assessment for the final project recommendation.
