The global off-grid solar market is set to grow from $1.9 billion in 2021 to $5.8 billion by 2031, driven by falling system costs, technology advances, and rising demand for decentralized energy in remote and rural regions.

According to a new report published by Allied Market Research, the off-grid solar market share was valued at $1.9 billion in 2021 and is projected to reach $5.8 billion by 2031, registering a robust CAGR of 12.3% from 2022 to 2031. This strong growth trajectory reflects rising demand for decentralized energy solutions, especially in regions with limited or unreliable grid infrastructure.

Introduction: Understanding Off-Grid Solar Systems

Off-grid solar refers to a power generation system that operates independently of the conventional electricity grid. These systems use solar photovoltaic (PV) panels, batteries, and power electronics to generate and store electricity for use in homes, businesses, and communities that lack access to centralized power networks or prefer energy self-reliance.

The off-grid solar market plays a crucial role in expanding energy access in remote and rural regions while supporting sustainability goals. By enabling decentralized electricity generation, off-grid solar reduces reliance on fossil fuels and costly grid expansion projects.

By Region

Region-wise, the off-grid solar market is analyzed across North America, Europe, Asia-Pacific, and LAMEA.

Asia-Pacific held the largest market share in 2021 and is projected to maintain its dominance throughout the forecast period. Rapid population growth, rural electrification programs, and supportive government policies in countries such as India and Southeast Asian nations are key growth drivers.

Africa and LAMEA regions also present significant growth potential due to widespread energy access gaps and increasing international funding for off-grid renewable energy projects.

Market Dynamics

Growth Drivers

One of the key factors driving the off-grid solar market growth is the significant decline in system costs over the past decade. Advancements in solar panel efficiency, battery storage technology, and power electronics have made off-grid solar systems more affordable and reliable. Improved panel efficiency allows higher energy output per unit area, while modern batteries offer better durability, longer lifespans, and greater storage capacity.

In addition, economies of scale in manufacturing and global supply chains have further reduced system prices. Compared to the high cost of extending transmission and distribution networks to remote areas, off-grid solar presents a cost-effective alternative for decentralized electricity generation. These benefits are accelerating adoption across residential, commercial, and industrial applications.

Opportunities

The off-grid solar market offers substantial opportunities through decentralized energy generation and economic empowerment. By reducing dependence on centralized power plants and long transmission lines, off-grid solar enhances energy resilience and minimizes the risk of outages caused by natural disasters or grid failures.

Moreover, access to reliable electricity supports productive activities such as agricultural processing, small businesses, and cottage industries. This leads to improved productivity, income generation, and overall economic development in underserved regions.

Continuous research and development in solar PV, battery storage, and energy management systems is fostering innovation. Emerging business models, including pay-as-you-go solar and community microgrids, are further expanding the market's potential.

Market Restraints

Despite its advantages, limited energy storage capacity remains a key restraint for the off-grid solar market. Most off-grid systems rely on batteries to store electricity for use during nighttime or periods of low sunlight. However, current battery technologies still face limitations related to capacity, lifespan, and performance during extended periods of cloudy or rainy weather.

High electricity demand during peak usage periods can exceed battery capacity, leading to power shortages. These challenges may restrict system reliability in certain applications, particularly in industrial settings with high and continuous energy requirements.

Segmentation Overview

The off-grid solar market share is segmented by application and region, offering insights into demand patterns and growth opportunities.

By Application

Based on application, the market is categorized into residential, commercial, and industrial segments.

The industrial segment dominated the market in 2021, driven by demand for reliable power in mining, manufacturing, and agricultural operations located in remote areas.

The residential segment is expected to be the fastest growing during the forecast period, supported by rising rural electrification initiatives and increasing adoption of solar home systems.

Competitive Landscape

The off-grid solar market is moderately fragmented, with global and regional players focusing on product innovation, strategic partnerships, and geographic expansion. Key players profiled in the market include ABB Ltd., Schneider Electric SE, Canadian Solar, Engie, SMA Solar Technology AG, Jinko Solar Holding Co. Ltd., SunPower Corporation, Delta Electronics, Greenlight Planet, and Hanwha Group.

These companies are investing in advanced solar modules, hybrid storage solutions, and digital energy management systems to improve system reliability and customer affordability.

Conclusion

The off-grid solar market is poised for strong growth over the next decade, supported by declining system costs, technological advancements, and the global push for universal energy access. While storage limitations pose challenges, ongoing innovation and supportive policies are expected to unlock new opportunities. Off-grid solar will continue to play a vital role in delivering sustainable, reliable, and affordable electricity worldwide.
