The video explains the complete installation process of a 5 kW rooftop solar system by UTL Solar with government subsidy.
1. Customer Inquiry & Inspection
✓ A customer contacts the company by phone or by visiting the shop.
✓ Engineers check the electricity bill to understand the current load and energy usage.
✓ A site visit is done to inspect roof space and determine how many kilowatts can be installed.
✓ If the customer’s approved electricity load is low, it can be increased through the electricity department.
2. Payment & Loan Option
✓ Total system cost is about ₹2.5 lakh.
✓ The government provides a ₹78,000 subsidy.
✓ Customers can get up to 90% loan at low interest, paying only 10% upfront.
✓ Loan repayment period can be up to 10 years in easy installments.
3. Material Delivery & Structure Installation
✓ All equipment is delivered to the house in one shipment.
✓ Engineers select the optimal panel angle to maximize sunlight exposure.
✓ A metal mounting structure is installed on the roof using drilling and base plates.
✓ Civil foundation work with cement and concrete is added to make the structure strong against wind and storms.
4. Panel Installation
✓ After the foundation dries, solar panels are mounted on the structure using clamps.
✓ Everything is tightened and secured because the system is designed to last 25+ years.
5. Wiring & Safety Setup
✓ Panels are connected using MC4 connectors (positive and negative).
✓ DC wiring runs through protective pipes for safety and a clean installation.
✓ A lightning arrester is installed.
✓ Three earthing systems are provided:
✓ Lightning arrester earthing
✓ Structure earthing
✓ Inverter earthing
6. Inverter & Electrical Safety Boxes
✓ A 5.3 kW inverter converts DC electricity from panels into AC power for household/grid use.
✓ DCDB and ACDB safety distribution boxes are installed.
✓ All wiring is enclosed to ensure electrical safety and neat appearance.
7. Net Metering
✓ A net meter from the electricity department will later be installed.
✓ This allows excess solar power to be exported to the grid.
8. System Specifications
✓ 10 solar panels of 525 W each (total ≈ 5.25 kW system).
✓ Panels are Indian-manufactured DCR TopCon panels eligible for subsidy.
✓ 27-year performance warranty on panels.
✓ 10-year warranty on the inverter.
9. Smart Features
✓ The inverter has a touch interface and fault indicator system.
✓ It includes Wi-Fi connectivity.
✓ Using the UTL Solar mobile app, users can monitor daily, monthly, and yearly electricity generation.
Final Cost
✓ Total installation cost: ₹2.5 lakh
✓ Government subsidy: ₹78,000
✓ Effective cost after subsidy: about ₹1.7 lakh
This system helps homeowners significantly reduce or even eliminate electricity bills by generating their own solar power.
