## **Step-by-Step: How Solar Panel Installation Actually Works**

[Solar panel installation](https://kondaas.com/) sounds technical, but it’s straightforward. Certified teams handle everything. Here’s exactly what happens when you say yes:

## **1. Free Home Assessment (Day 1)**

A technician visits your home. They check:

- Roof space and sunlight hours (most Indian homes get 4-6 peak sun hours daily)
- Your electricity bills (to size the perfect system)
- Shading from trees or buildings

**Result**: Custom quote showing exact system size (1kW, 3kW, 5kW) and subsidy eligibility. It takes 30-60 minutes.

## **2. System Design & Paperwork (Week 1)**

Your installer designs the layout and handles approvals:

- Net metering permission from electricity board
- Subsidy application on pmsuryaghar.gov.in
- Electrical safety certificates

> **You do nothing,**they manage all bureaucracy. Most approvals take 7-15 days.

## **3. Installation Day(s) (2-3 Days Total)**

**Morning**: Team installs mounting racks (15-20° south-facing tilt for max sun capture).
**Afternoon**: Fix high-efficiency panels (540W each), connect wiring.
**Day 2**: Install inverter (converts solar DC to home AC power), net meter, safety earthing.

Professional teams use stainless steel clamps, anti-corrosion bolts, and weatherproof wiring built for Indian monsoons.​

## **4. Inspection & Grid Connection (Day 4)**

Electricity inspector verifies safety. The system switches on. You start generating free power immediately. Excess power feeds the grid for bill credits.

**Total timeline**: 2-4 weeks from quote to power generation.
