Made in India, Powering America: The Rise of Indian Solar Modules in the US Market

The global solar industry is witnessing a shift. At the heart of this shift lies India’s rise as America’s solar manufacturing partner of choice.

Just three years ago, India’s solar module exports to the world totaled $85 million. Today, that figure has grown to billions, signaling a fundamental shift in the global solar ecosystem. Indian manufacturers have emerged as the reliable, quality-driven partners the world has been looking for.

The Numbers That Changed Everything

The numbers tell a clear story of market dominance. According to a report by the Institute for Energy Economics and Financial Analysis (IEEFA) and JMK Research, India’s solar module exports hit $2 billion in fiscal 2024 which is a massive jump from previous years. What’s more important is how the United States has become India’s main customer, taking 97% of India’s solar exports in fiscal 2023 and 99% in fiscal 2024.

This goes beyond just numbers, it’s about trust. When American solar companies put almost all their Indian solar purchases in one market, it shows they believe in the quality and reliability of Indian manufacturing. The data shows that India has taken over the India-to-America solar trade.

India also surpassed South Korea last year to become the fifth-largest solar exporter to the United States. This puts Indian manufacturers among the top suppliers to the world’s second-largest solar market, showing how quickly the industry has grown and focused on strategy.

Convergence of Market Forces

Several connected factors have created the right conditions for India’s solar export boom, each one strengthening the others to build momentum that keeps growing.

Supply Chain Diversification Imperative

The “China Plus One” strategy has become a must-have. Companies around the world are working to diversify their supply chains and reduce their dependence on single-source manufacturing. India has become the best alternative, offering manufacturing capability, competitive costs, and political stability that few other countries can provide.

This diversification is about managing risk and creating strong, sustainable supply chains that can handle global disruptions while keeping quality high and costs reasonable. Indian manufacturers have positioned themselves perfectly to meet this demand.

Domestic Market Dynamics Creating Export Opportunities

India’s own policy changes have actually helped boost exports. The delayed implementation of the Approved List of Models and Manufacturers (ALMM) in April 2024 temporarily reduced domestic demand for solar modules. Instead of seeing this as a problem, Indian manufacturers shifted their focus to international markets, especially the United States.

Evolving Trade Landscape

The end of certain Free Trade Agreements and ongoing antidumping and countervailing duty investigations have changed the competitive landscape. With these changes, India could potentially replace Southeast Asian countries as the leading solar exporting region to the United States. This shift represents a chance for Indian manufacturers to build long-term partnerships with American stakeholders.

Strategic Benefits: A Partnership That Works

The surge in Indian solar exports to America benefits both markets in ways that go far beyond trade numbers.

For Indian manufacturers, working in the demanding US market drives improvement and growth. As Vibhuti Garg, Director – South Asia at IEEFA and contributing author of the key report, explains: “Focusing on the US market can benefit the Indian PV manufacturing ecosystem. The exposure to the US market will enable Indian PV manufacturers to attain economies of scale, ultimately enhancing their product quality and competitiveness.”

This touches on a basic principle of manufacturing excellence: demanding customers drive innovation and quality improvements that benefit everyone. American buyers, known for their strict standards and quality requirements, push Indian manufacturers to continuously improve their processes, products, and capabilities.

GREW Solar: Leading India’s Manufacturing Excellence

Within this broader story of Indian solar success, GREW Solar shows how Indian manufacturers are not just participating in the American market but leading it through innovation, quality, and strategic vision.

GREW Solar’s approach to the American market reflects the broader Indian strategy of delivering superior quality products that meet the high standards of US buyers while maintaining the cost competitiveness that makes solar energy accessible and economical. With manufacturing facilities strategically located across 350+ acres in Rajasthan, Madhya Pradesh, and Jammu & Kashmir, GREW Solar has built the scale and capability needed to serve large American projects while maintaining the flexibility to meet diverse customer requirements.

The UFLPA-compliant supply chain addresses one of the most critical concerns for American buyers i.e. transparency and ethical sourcing. In a market increasingly focused on supply chain integrity, GREW Solar’s commitment to responsible manufacturing practices provides American customers with the confidence they need to specify its products for their projects.

The Road Ahead

The transformation of India from a small player to a major force in the American solar market represents the emergence of a sustainable, long-term partnership that benefits both nations’ clean energy goals.

For India, success in the American market proves the country’s manufacturing capabilities and opens doors to other international opportunities.

How Much Roof Space Do You Need for Solar Panels?

Introduction

Thinking of installing solar panels on your rooftop? One of the first questions homeowners ask is, “How much roof space do I need for solar panels?” This is a smart question because the amount of space on your roof directly affects how many panels you can install, how much electricity you can generate, and how much money you can save in the long run.

Whether you’re planning to lower your electricity bills, reduce your carbon footprint, or invest in a long-term energy solution, understanding the space required for solar panels is essential. In this guide, we break it down simply and clearly, helping you figure out what you need, what to check for, and how to plan a rooftop solar system for your home in India.

Solar panels are not one-size-fits-all. The number of panels — and thus the space you need — depends on your energy consumption, the type of solar panels you use, and the layout of your rooftop. This makes early planning essential. A good understanding of these factors will help you make smarter choices, whether you’re going fully off-grid, partially offsetting your energy usage, or exploring government subsidy benefits.

Understanding the Basics of Solar Panels

Before calculating space, let’s look at the basics:

What is a solar panel? A solar panel is made of photovoltaic (PV) cells that convert sunlight into electricity.

Types of Solar Panels

Monocrystalline (efficient, compact, slightly more expensive)

Polycrystalline (affordable, needs more space)

Thin-film (flexible, less efficient, needs lots of space)

Each panel type has different energy efficiency ratings. For example, monocrystalline panels can reach up to 20–22% efficiency, meaning they need less surface area to produce the same power. On the other hand, polycrystalline panels usually have 15–17% efficiency, requiring more rooftop space.

Average Size of a Solar Panel Standard residential solar panels in India are around 6.5 feet by 3.2 feet (roughly 21 square feet) and have a capacity of about 330 to 550 watts per panel. So, if your home requires 3 kW of solar energy, and you choose 450W panels, you’ll need approximately 7 panels.

How Much Electricity Does Your Home Need?

The next step is figuring out how much power your home uses.

Step-by-step Guide:

Check your electricity bill: Look at your last 6–12 months.

Average monthly usage: In India, average households use 200–500 units (kWh) per month.

Target offset: Most homeowners aim to cover 70–100% of their usage.

Example: If your average usage is 400 kWh/month, and you want to offset 100%, you’ll need a 4 kW system.

Each kilowatt of solar capacity generates around 120–140 units per month in most Indian cities. So, a 4 kW system can generate around 5,000–6,000 units per year.

How to Calculate Roof Space for Solar Panels?

Now, the big question: how much area do you need for a 1 kW solar system?

1 kW system = 3 to 4 solar panels

Area required per kW = 80 to 100 sq. ft. (for standard panels)

Area Required Table

Pro Tip: Use a solar panel roof space calculator or consult with a solar EPC company like The Grew Solar to get an exact estimate based on your panel type and roof design.

Additionally, some space will be lost due to panel spacing, tilt angle, and pathways for maintenance access. Always plan for 10–15% more space than the bare minimum.

Factors That Affect Space Requirement

Not all roofs are created equal. Here are things that may affect your usable roof space:

Shade from trees, water tanks, AC units, or nearby buildings

Direction and tilt of the roof (south-facing is ideal in India)

Roof shape (flat roofs vs sloped roofs)

Ventilation pipes or obstructions

Legal building codes or society norms

Roof Orientation

A south-facing roof receives the most sunlight throughout the day in India. East and west-facing roofs still work, but efficiency drops by about 10–20%.

Roof Type

Flat concrete rooftops are ideal for customizable mounting angles and efficient layout. Sloped roofs need specialized mounting and may have limited usable space.

Real-Life Examples from Indian Homes

Let’s see how this plays out for different homes:

Case Study 1: 2 BHK Apartment in Ahmedabad

Average bill: ₹1,500/month

Installed: 2 kW system

Roof space used: 180 sq. ft.

Savings: ₹13,000/year

Payback: 5.5 years

Case Study 2: Independent Villa in Bangalore

Average bill: ₹2,800/month

Installed: 5 kW system

Roof space used: 420 sq. ft.

Savings: ₹35,000/year

Payback: 4.5 years

Case Study 3: Duplex in Delhi

Monthly usage: 600 kWh

Installed: 6 kW system

Roof space used: 540 sq. ft.

ROI: 16–18% annually

Payback: 4.2 years

How to Maximize Your Roof Space?

Tips to make the most of what you have:

Choose monocrystalline panels for higher efficiency

Go for elevated mounting structures if roof space is small

Consider solar carports or awnings for extra panel space

Use part of your garden, backyard, or boundary wall for hybrid layouts

Keep the panels clean and maintain optimal angles

Use east-west mountings for higher density installations

If you’re short on space, focus on maximizing efficiency per square foot. Newer technology even offers bifacial panels that absorb light from both sides.

Structural Load and Roof Strength

Each solar panel weighs about 18–25 kg. With mounting structures, the load is typically 10–15 kg per square meter.

Concrete rooftops in India are usually designed to handle up to 150 kg/sq. m, so solar panels pose no threat to structural safety. Still, it’s a good idea to have a site engineer inspect your roof before installation, especially for older buildings.

Frequently Asked Questions (FAQs)

Q: Can I install solar if my roof is small? A: Yes. Even 100 sq. ft. can support a 1 kW system using high-efficiency panels.

Q: What if I have shade on my roof? A: Partial shade reduces efficiency. Consider microinverters or choose a different location on your property.

Q: How heavy are solar panels? Will my roof support them? A: Most panels weigh 18–25 kg each. Normal concrete roofs in India easily support them.

Q: Can I expand the system later if I don’t have space now? A: Yes. Modular solar setups let you add more panels later.

Q: Is there a minimum system size for net metering in India? A: Most states require at least 1 kW to apply for net metering benefits.

Final Thoughts: Plan Smart, Save Big

Knowing how much roof space you need for solar panels is the first step to a greener, more cost-effective home. By understanding your power needs, panel types, and space options, you can design the perfect rooftop solar system.
