Installation Guide for a 15kW Solar Panel System
Step 1: Assess Your Energy Needs
Calculate your average electricity consumption to determine if a 15kW system is sufficient for your needs.
Step 2: Site Inspection & Feasibility Study
A solar expert will inspect your roof or land to ensure it receives enough sunlight and has the capacity to install solar panels.
Step 3: Choose the Right Solar System
Decide whether you need an on-grid, off-grid, or hybrid system based on your energy consumption and budget.
Step 4: Get Approval & Apply for Subsidy
If you are installing an on-grid system, apply for subsidy approval from the government portal.
Step 5: Installation & Net Metering
The solar panels, inverter, and batteries (if required) are installed. For on-grid systems, a net meter is installed to track electricity generation and usage.
Step 6: Inspection & Commissioning
After installation, authorities inspect the system, and once approved, you can start using solar power.
