Solar Panel Installation: A Step-by-Step Guide (2026)

In 2026, solar energy in India is no longer just a trend—it’s a household standard. Because the PM Surya Ghar Muft Bijli Yojana aims to empower 1 crore households, the installation process is now more streamlined. Furthermore, new mandatory BEE efficiency standards for inverters started on January 1, 2026, which means systems are now strictly regulated for quality.

If you are planning to switch, this definitive solar panel installation guide for 2026 ensures your system remains efficient, compliant, and ready to save you money. You can start your journey today with the experts at Solar Squad.

Installing solar panels is a long-term investment. While the physical setup usually takes only 2–4 days, the planning and quality checks determine if your system will last for the next 25 years. Consequently, Solar Squad follows a rigorous 10-step process to ensure peak performance.

Phase 1: Planning and Digital Mapping

Step 1: Energy Audit & Load Analysis Before you buy a single panel, you must know your “solar appetite.” First, our team analyzes your last 12 months of electricity bills. We also account for “future-proofing”—specifically, whether you plan to add an EV charger or another AC later in 2026. Typically, most Indian homes require a 3 kW to 5 kW system.

Step 2: Digital Site Assessment Modern installers now use drones and 3D mapping to evaluate your property. Specifically, this technology helps us identify “shadow-free” zones and determine the Optimal Tilt Angle. This ensures your roof meets the standards set by the Ministry of New and Renewable Energy (MNRE).

Phase 2: Compliance and Structural Foundation

Step 3: Paperwork & DISCOM Feasibility In 2026, the PM Surya Ghar Portal acts as the central hub for all applications. Therefore, Solar Squad applies for Technical Feasibility from your local DISCOM on your behalf. Once the department issues the “Sanction Letter,” we can legally begin the physical installation.

Step 4: Mounting Structure Installation The mounting structure serves as the “backbone” of your system. In 2026, we exclusively use high-quality Hot-Dip Galvanized (HDG) or Aluminum structures to prevent rust. Additionally, we apply specialized chemical anchoring to fix the legs, which ensures zero roof leakage even during heavy monsoons.

Phase 3: Panel Setup and Electrical Safety

Step 5: Solar Panel Mounting Once the structure is stable, our technicians bolt down the modules. For instance, in 2026, TOPCon Bifacial panels are the most popular choices. Under the latest ALMM (Approved List of Models and Manufacturers) regulations, only certified high-efficiency cells can be used in subsidized projects.

Step 6: Electrical Wiring & MC4 Connections Safety is paramount during this stage. For this reason, we use UV-protected DC cables to prevent cracking under the harsh Indian sun. Furthermore, we use MC4 Connectors for all inter-panel connections to create a waterproof and secure electrical link.

Step 7: Inverter Installation (BEE Standard Compliant) As of January 2026, all on-grid inverters must meet new BEE efficiency standards. The inverter acts as the “brain” of the system. We ensure your inverter is BIS-certified (Bureau of Indian Standards) so you remain eligible for government subsidies.

Phase 4: Protection and Grid Integration

Step 8: Earthing & Lightning Protection To protect your home from electrical surges, we install Lightning Arrestors (LA) at the highest point of your roof. Simultaneously, we dig separate earthing pits for the structure, the DC side, and the AC side to maximize safety.

Step 9: Net Metering & Grid Integration Once the system is physically ready, a DISCOM inspector verifies the installation. After approval, the utility company replaces your old meter with a Bi-directional Net Meter. Consequently, this device tracks both the energy you consume and the energy you export back to the grid.

Step 10: System Commissioning & Monitoring Finally, we flip the switch! Most 2026 systems come with Mobile App Monitoring so you can see your production in real-time. To conclude, Solar Squad provides a final walkthrough to show you how to maintain your panels for maximum yield.

Why Professional Solar Panel Installation Matters in 2026

With the new ALMM List-II mandatory for solar cells since June 2026, sourcing the right components has become highly technical. Although DIY installations may save money today, they often lead to subsidy rejection.
