🌞 A Complete Guide to Installing and Sizing a 5 kW Solar System (Using Tata Power Solar) – ecogreenxp.com

Switching to solar energy is a powerful step toward energy independence and reducing your carbon footprint. If you’re considering a 5 kW solar system for your home or small business, this comprehensive guide will walk you through everything – from sizing, choosing components, installation, and cost estimation – using Tata Power Solar, one of the most trusted vendors in India.

✅ What Is a 5 kW Solar System?

A 5 kilowatt (kW) solar system generates approximately 20–25 units (kWh) of electricity per day under optimal conditions. It’s ideal for:

• Medium-sized homes (3–4 BHK)
• Small offices or shops
• Energy-efficient homes with ACs, fridges, washing machines, etc.

📏 Step-by-Step Sizing and Installation Process

1. Energy Consumption Analysis

First, assess your monthly power usage:

With this usage, a 5 kW system generating ~22–25 kWh/day is ideal.

2. Available Rooftop Space

A typical 5 kW system requires:

• 350–400 sq. ft. of shadow-free roof area
• South-facing (or optimal angle depending on your latitude)

If space is constrained, high-efficiency monocrystalline panels are preferred.

3. System Types: On-Grid vs Off-Grid vs Hybrid

Recommended: On-grid system with net metering for urban users

4. System Components (Tata Power Solar)

Solar Panels:

• Type: Mono PERC / Mono Half-Cut
• Example: Tata Solar Mono PERC 550 Wp
• Number of panels: 9–10 panels of ~550 Wp each

Inverter:

• Type: String inverter or Micro-inverter
• Suggested: SMA, Huawei, or Tata Solar inverter
• Rating: 5 kW, MPPT-enabled

Mounting Structure:

• Rust-proof, galvanized iron
• Fixed tilt (south-facing, ~20–25° angle in India)
