“Are you planning to install rooftop solar but don’t know where to start? 🤔
Here are 7 must-know tips that will help you save more money, choose the right system, and get the most out of your solar investment!”
Tip 1: Check Your Roof Space & Direction
Make sure your roof gets direct sunlight for 5–6 hours a day.
South-facing rooftops (in India) are best for maximum power generation.
📌 Pro Tip: Avoid shaded areas from trees or water tanks.
⚙️ Tip 2: Choose the Right Capacity for Your Needs
Calculate your monthly electricity usage (in units).
1 kW solar = approx. 4 units/day = ~120 units/month.
If your bill is ~360 units/month → go for a 3 kW system.
💸 Tip 3: Use Government Subsidy Programs
Residential solar users can get up to ₹78,000 subsidy under national schemes.
Apply through the MNRE portal or ask your installer to assist.
🔌 Tip 4: Understand On-Grid vs Off-Grid vs Hybrid
✅ On-Grid: Cheaper, no batteries, uses net metering.
🔋 Off-Grid: Works during power cuts but costs more.
⚡ Hybrid: Best of both worlds – slightly higher cost but maximum reliability.
🛠️ Tip 5: Pick BIS-Certified Panels & Inverters
Always choose Tier-1 panels with at least 25 years warranty.
Good inverter = higher efficiency and longer lifespan.
🧼 Tip 6: Clean Panels Every 15–30 Days
Dust reduces power generation by 10–20%.
Light cleaning with water and soft cloth is enough – no chemicals needed.
📱 Tip 7: Monitor Your System Regularly
Use the mobile app provided by your installer to track daily generation.
If output drops suddenly, call your service provider for a quick check.
