Who Should Read This?

This guide is for:

• Homeowners exploring solar for the first time.

• Current solar users wondering why their system shuts down during blackouts.

• Anyone looking to protect their home from unexpected power outages.

Why Do Power Outages Happen—and Why Does It Matter for Solar Users?

India’s electricity grid, while improving rapidly, is still prone to outages caused by:

• Summer overloads (especially in Tier 2/3 cities and rural areas)

• Storms and weather-related faults

• Maintenance or infrastructure issues

When the power goes out, the behavior of your solar system depends on which type you’ve installed.

Types of Solar Systems and How They Respond to Outages

1. Grid-Tied Solar Systems (Most Common in India)
   “Why doesn’t my solar system work during a power cut?”

How it works:

• Panels generate power and send excess energy to the grid (net metering).

• During outages, the system automatically shuts down (anti-islanding) to protect utility workers.

Result during outage: Your home won’t get power, even if it’s sunny.

2. Off-Grid Solar Systems (For Full Independence)
   “How can I keep my home powered without relying on the grid?”

How it works:

• Completely disconnected from the grid.

• Batteries store excess solar energy, powering your home 24/7.

Result during outage: Uninterrupted power, regardless of grid failures.

Best for: Remote areas, farms, or homes with frequent outages.

3. Hybrid Solar Systems (Backup + Savings)
   “Is there a system that gives me savings and backup?”

How it works:

• Connected to the grid (for net metering).

• Includes batteries that store power for emergencies.

• Smart inverters switch to battery mode during blackouts.

Result during outage: Lights stay on, appliances keep running.

Best for: Urban households wanting both savings and security.

Why Battery Backup Matters (And How Asian Powertech Helps)

Most grid-tied systems in India don’t come with battery backup by default—but Asian Powertech’s systems are battery-ready, meaning you can add storage anytime.

Benefits of Solar Battery Backup:

• Power Security: Stay powered during grid failures.

• Cost Optimization: Use stored energy at night or during peak rates.

• Peace of Mind: Critical loads like lights, Wi-Fi, fans, and fridges keep running.

“With battery storage, you’re not just saving on bills—you’re buying energy freedom.”

What’s the Cost of Adding Battery Backup?

Adding battery storage is an investment—but one that pays off over time. Factors affecting cost:

• Backup Size Needed: Full home or essential loads only?

• Solar System Type: Hybrid or new installation?

• Battery Brand & Capacity: Lead-acid, lithium-ion, etc.

Asian Powertech provides a free, personalized solar evaluation to help you understand:

• Upfront vs. long-term costs

• Payback period

• Available financing options or solar PPAs (Power Purchase Agreements)

Should You Wait to Add Batteries Before Going Solar?

No! Many homeowners start with a standard grid-tied system and add batteries later as needs evolve.
