Installing rooftop solar in Noida follows a clear sequence: you choose an installer, complete approvals, get the system installed, and then switch on net‑metered solar power. The process is similar across Uttar Pradesh but involves specific steps with your local DISCOM and the national rooftop solar portal.
Step 1: Assess Your Home and Shortlist an Installer
Start by checking your last 6–12 months of electricity bills to understand your average monthly units and sanctioned load. This helps decide the right system size for your Noida home. Next, shortlist a few rooftop solar companies active in Noida, such as SIA Solar and other empanelled vendors, and request a site visit and basic proposal.
Step 2: Site Survey and Technical Design
Your chosen installer will conduct a detailed site survey, measuring roof space, checking structure strength, and studying shading from nearby buildings or trees. They also inspect your existing wiring, meter location, and main distribution board, then prepare a system design showing panel layout, inverter sizing, safety devices, and expected yearly generation.
Step 3: Apply on the National Rooftop Solar Portal
For subsidy‑linked systems under PM Surya Ghar, you must register your Noida home on the National Rooftop Solar portal. The installer usually helps you upload documents like your electricity bill, ID proof, property details, and proposed plant size, after which the local DISCOM carries out feasibility checks.
Step 4: Net Metering and Local DISCOM Approvals
In Noida, net‑metering for rooftop solar is processed by the local DISCOM (for example, NPCL in certain areas) following state regulations. After technical scrutiny and approval, the DISCOM issues permissions and confirms that your proposed solar capacity matches your sanctioned load and grid safety norms.
Step 5: Actual Installation on Your Roof
Once approvals are in place, the installer mobilises materials and starts physical work at your home. They fix mounting structures, install solar panels at the optimum tilt and orientation, run DC and AC cables, connect the inverter, provide proper earthing, and integrate surge and safety protection as per standards. After wiring, they test the system, verify all electrical connections, and prepare documentation such as single‑line diagrams and completion reports.
Step 6: Meter Change, Commissioning, and Subsidy Processing
The DISCOM then schedules an inspection and replaces your existing meter with a bidirectional net meter that records both import and export of electricity. After successful inspection and synchronisation with the grid, your rooftop solar system is officially commissioned, and your installer uploads post‑installation documents so that eligible subsidies can be processed into your bank account.
FAQs
Q1. How long does it take to install rooftop solar for a Noida home?
Physical installation usually takes a few days, while approvals, net‑metering, and subsidy processes can extend the overall timeline to several weeks.
Q2. Do I need to apply myself on the rooftop solar portal?
Yes, the application is in your name on the national portal, but your installer generally assists with filling forms and uploading documents.
Q3. Is net‑metering mandatory for Noida rooftop solar systems?
Net‑metering is strongly recommended for grid‑connected homes in Noida because it allows you to export surplus power and receive credits on your bill.
Q4. Who handles inspections and meter replacement in Noida?
Your local DISCOM manages technical inspections and installs the bidirectional net meter once your rooftop system is ready and compliant.
Q5. When is the solar subsidy released to homeowners?
Subsidy is typically released to the homeowner’s bank account after commissioning, inspection, and successful verification of all documents on the rooftop solar portal.
