Solar Dryer Market Growing at 8.02% CAGR from 2025-2035 | Market Research Future Market Perspective

According to MRFR analysis, the solar dryer market stood at USD 17.62 billion in 2024. It is expected to grow from USD 19.03 billion in 2025 to USD 41.17 billion by 2035, achieving a CAGR of 8.02% during the forecast period.

The solar dryer market is gaining increasing importance as industries and agricultural communities seek energy-efficient and sustainable methods for drying food and other products. Solar dryers use solar energy to remove moisture from crops, food items, herbs, fish, and industrial materials, helping preserve quality while reducing energy consumption. Compared to traditional open sun drying or fuel-based dryers, solar dryers offer improved hygiene, faster drying times, and better control over drying conditions.

With rising concerns over energy costs, food waste, and environmental sustainability, solar dryers are emerging as a practical solution across agriculture, food processing, and small-scale industries. Their ability to extend shelf life, maintain nutritional value, and reduce post-harvest losses is driving steady growth in the global solar dryer market.

Market Drivers

One of the major drivers of the solar dryer market is the increasing focus on reducing post-harvest losses in agriculture. A significant percentage of fruits, vegetables, grains, fish, and spices are lost each year due to improper drying and storage. Solar dryers provide a controlled drying environment that minimizes spoilage, improves product quality, and enhances income for farmers and producers.

Rising energy costs and limited access to electricity in rural and remote areas are also fueling demand for solar dryers. Conventional mechanical dryers rely on electricity or fossil fuels, which can be expensive or unreliable. Solar dryers offer a low-cost and decentralized alternative, making them especially attractive in developing regions with abundant sunlight.

The growing emphasis on sustainable and renewable energy solutions further supports market growth. Solar dryers operate using clean solar energy, reducing greenhouse gas emissions and dependence on non-renewable fuels. Governments, non-governmental organizations, and development agencies are promoting solar drying technologies as part of broader clean energy and climate resilience programs.

The expanding food processing and agro-based industries are contributing to increased adoption of solar dryers. Demand for dried food products such as fruits, vegetables, herbs, spices, and seafood is rising due to changing dietary habits and increased awareness of food preservation. Solar dryers help maintain color, flavor, and nutritional value, making them suitable for both domestic consumption and export markets.

Additionally, increasing awareness of food safety and hygiene is driving the shift from traditional open sun drying to enclosed solar drying systems. Solar dryers protect products from dust, insects, animals, and environmental contaminants, improving overall quality and meeting food safety standards.

Technology Advancement

Technological advancements are significantly enhancing the efficiency, versatility, and usability of solar dryers. One of the key developments is the improvement in dryer design and airflow management. Modern solar dryers use optimized air circulation systems, improved insulation, and better heat retention materials to ensure uniform and faster drying.

Indirect solar dryers are gaining popularity due to their ability to prevent direct exposure of products to sunlight. By separating the solar collector from the drying chamber, these systems help preserve color, nutrients, and texture, making them ideal for high-value crops such as fruits, herbs, and medicinal plants.

Hybrid solar dryers represent another important technological trend. These systems combine solar energy with auxiliary heating sources such as biomass, electricity, or heat storage systems. Hybrid dryers ensure continuous operation during cloudy weather or at night, improving reliability and productivity, especially for commercial-scale operations.

Advancements in thermal energy storage are also influencing the market. The integration of phase change materials and thermal storage units allows solar dryers to store heat during peak sunlight hours and release it during low-sun periods. This enhances drying efficiency and reduces dependence on backup energy sources.

Digital monitoring and control technologies are increasingly being adopted. Sensors and controllers help monitor temperature, humidity, and airflow in real time, enabling better control over drying conditions. These features improve product consistency, reduce drying time, and minimize energy losses.

Manufacturers are also focusing on modular and portable designs. Compact, easy-to-install solar dryers are particularly beneficial for smallholder farmers and rural communities. Lightweight materials, corrosion-resistant structures, and low-maintenance designs improve durability and ease of use, supporting wider adoption.
