Panel Installation
Our Solar Panel Installation Process
At ADV Green Energy, we believe in a methodical approach that guarantees safety, efficiency, and maximum return on investment for our clients in Patna, Bihar. Our certified technicians follow a rigorous 7-step process tailored to local regulations and the specific climate conditions of the region.
Here is how we bring sustainable power to your doorstep:
Step 1: Initial Consultation & Site Assessment
Everything begins with understanding your energy needs.
- Energy Audit: We analyze your current electricity bills to determine the optimal system size you require.
- Structural Evaluation: Our civil experts visit your Patna location to inspect your roof’s condition, orientation, and structural integrity. This ensures your roof is “solar-ready.”
Step 2: Custom System Design & Proposal
We design a bespoke solar solution, not a one-size-fits-all package.
- Shade Analysis: Using advanced software, we identify potential shading issues (from trees, nearby buildings) to optimize panel placement.
- Component Selection: We select high-efficiency Monocrystalline panels and appropriate inverters (On-Grid or Off-Grid) that suit your budget and energy goals.
- Financial Breakdown: You receive a transparent proposal detailing costs, estimated energy production, ROI, and eligible government subsidies (like the PM-Surya Ghar Yojana).
Step 3: Paperwork & Government Approvals
Navigating bureaucracy can be complex; we handle it for you.
- Permitting: We manage all necessary approvals with local Patna Municipal authorities and the Bihar State Power Holding Company Limited (BSPHCL).
- Subsidy Assistance: We facilitate your application process for central and state-level renewable energy incentives.
Step 4: Procurement & Logistics
Once approvals are in place, we schedule the installation.
- Quality Components: We utilize only GST-compliant, certified components sourced directly to ensure quality assurance (GSTIN: 10CJHPS7712P1ZS).
- Delivery: All equipment is transported securely to your site in Patna.
Step 5: Professional Installation
This is where the transition happens. Our certified and insured installation team executes the plan safely and efficiently.
- Mounting Structure Setup: Installation of robust, weather-resistant mounting systems.
- Panel & Wiring: Secure attachment of solar panels and professional DC/AC wiring integration.
- Safety First: We adhere strictly to all safety standards during the entire installation process.
Step 6: Inspection & Commissioning (Net Metering)
We ensure everything is connected and legally compliant.
- Utility Inspection: The local utility company inspects the system to ensure it meets grid standards.
- Net Meter Installation: For on-grid systems, we coordinate the installation of your bi-directional meter so you can start selling excess power back to the grid.
- System Activation: We flip the switch and your home starts generating clean electricity!
Step 7: Monitoring & Maintenance Handoff
Our support doesn’t end after activation.
- System Monitoring: We set up real-time monitoring apps on your smartphone so you can track energy production instantly.
- Training & Handoff: We walk you through your new system and provide maintenance guidelines.
- O&M Services: Optional annual maintenance packages are available for worry-free solar ownership.
