1. DIY SOLAR HOME SYSTEM

1.1. MODULE 1

Module 1: Introduction to Solar Home Systems

1. Solar Energy Basics

Key Notes:

  • Solar energy comes from the sun → converted to electricity via photovoltaic (PV) panels.

  • How it works:

    • Sunlight hits solar panels → generates DC electricity.

    • Inverter converts DC → AC (used in homes).

    • Excess power can be stored in batteries or fed back to the grid.

2. Benefits of Solar Home Systems (SHS)

Key Notes:
✔ Cost-saving – Reduces electricity bills.
✔ Reliable – Works in off-grid areas.
✔ Eco-friendly – No pollution, reduces carbon footprint.
✔ Low maintenance – Few moving parts, long lifespan (20-25 years).


"Why Go Solar?"

  • 💰 Save Money 

  • 🌍 Clean Energy 

  • ⚡ Energy Independence 

3. Types of Solar Home Systems

System Type Best For Pros Cons
On-Grid Homes with grid access - Lower cost (no batteries)
- Sell excess power		 - No power during grid outages
Off-Grid Remote areas, no grid - Works 24/7 with batteries
- Full independence		 - Expensive (batteries needed)
Hybrid Best of both worlds - Uses grid + batteries
- Backup power		 - Higher upfront cost
