Introduction

With electricity prices rising year after year, rooftop solar systems have become a powerful solution for Indian homes. The PM Surya Ghar Muft Bijli Yojana has further encouraged this shift by offering subsidies up to ₹78,000 for solar installations. But once your solar panels are installed, how do you make sure they perform at their best?

In this post, we’ll explore practical, India-specific ways to maximize the efficiency of your solar power system—so you get more energy, greater savings, and faster return on investment.

‍

1. Choose the Right Panel Type

Not all solar panels are created equal. For Indian rooftops, especially in sunny states like Bihar:

• Mono PERC or TopCon Bifacial panels are highly efficient and perform well even in partial shade.
• Ask your installer (like Ghar Ghar Solar) for panels with efficiency of 19% or higher.

‍

2. Optimize Panel Direction & Tilt

In India, solar panels should face:

• South for year-round efficiency
• Tilted at an angle equal to your location’s latitude (approx. 25°–30° for Bihar)

This ensures your panels get maximum sunlight throughout the day.

3. Keep Panels Clean (Especially in Dusty Regions)

Dust, bird droppings, and pollution can reduce efficiency by 15–20%. Clean your panels:

• Every 2–4 weeks, using soft water and cloth
• Early morning or late evening to avoid thermal shock

Ghar Ghar Solar offers annual maintenance contracts to handle this professionally.

4. Use a Wi-Fi Enabled Inverter

Modern inverters let you:

• Monitor power generation live
• Track performance via app
• Detect underperformance early

We install smart inverters as standard for all Bihar installations.

5. Match Load Usage to Solar Generation

Use heavy appliances (like washing machines, water pumps, or air conditioners) during daytime when your solar system is generating the most.

Tip: Shift your electricity usage between 10 AM – 4 PM to rely more on solar, and less on grid.

6. Install a Net Meter

A net meter allows you to:

• Export excess electricity back to the grid
• Get credits on your electricity bill
• Track exact savings

Ghar Ghar Solar manages your net metering application from start to finish.

7. Maximize Government Benefits (PM Surya Ghar Yojana)

With this scheme, homeowners can receive:

• ₹30,000 for 1kW system
• ₹60,000 for 2kW
• ₹78,000 for 3kW or more

Apply through pmsuryaghar.gov.in, or let Ghar Ghar Solar handle it for you. We’re already installing 100+ systems in Bihar under this scheme.

8. Schedule Annual Inspections

A yearly inspection by certified technicians can help detect:

• Wiring issues
• Panel wear & tear
• Inverter errors

This ensures long-term health of your system and maximizes your ROI.

Real Example: Patna Family Saves ₹2,800/Month

A 3kW system installed by Ghar Ghar Solar in Kankarbagh, Patna:

• Subsidy claimed: ₹78,000
• Bill before solar: ₹3,200/month
• Bill now: ₹300–500/month
• ROI: Less than 4 years

Conclusion

A solar system isn’t “set and forget”—a little care and smart usage can go a long way in maximizing savings.
Whether you already have a system or are considering one under the PM Surya Ghar Yojana, following these tips will ensure your system performs at its best.
