Yiwu PV & Energy Storage Expo

In early summer of May, a gathering of thousands of merchants. From May 7 to 9, 2026, the much-anticipated "2026 Yiwu Solar PV & Energy Storage Application Products Expo" was grandly held at the Yiwu International Expo Centre.

On-the-Spot: Why Are Solar Air Conditioners So Popular?

At our booth, purchasers from Pakistan, Nigeria, Saudi Arabia and other countries frequently stopped by. The focus of their attention was highly consistent: in regions with power shortages, unstable electricity supply, or high electricity costs, how can one enjoy cooling at a low cost?

The answer provided by solar air conditioners is — letting the sun directly power the air conditioner.

Unlike the simple combination of a "regular air conditioner + rooftop solar panels", the solar air conditioner showcased by our company adopts hybrid AC/DC drive technology. It can be directly connected to solar panels, enabling an intelligent power supply mode that prioritizes solar power while using the grid as a supplement. During periods of ample sunlight, the system can operate completely off-grid, achieving "zero-electricity-cost cooling". On cloudy or rainy days, or at night, it automatically switches to grid or battery storage power, ensuring worry-free operation around the clock.

This technical approach perfectly aligns with the market demands of regions such as the Middle East, Africa, and Southeast Asia — areas that not only have abundant sunlight resources but also experience high temperatures year-round with significant cooling needs. At the same time, these regions face unstable grid coverage and continuously rising electricity costs. As a result, the value of solar air conditioners is greatly amplified.

Technical Interpretation: The Core Competitiveness of Solar Air Conditioners

Drawing on industry exchanges and market feedback from this exhibition, the competitive advantages of solar air conditioners can be summarized into the following three points:

1. High Supply-Demand Match: "It's Hot When the Sun Shines"

The greatest feature of solar air conditioners lies in the temporal synchronization between energy supply and load demand. The midday period in summer coincides with both peak cooling demand and peak solar radiation. This natural "supply-demand match" makes the system efficiency of solar air conditioners far superior to ordinary self-consumption photovoltaic solutions.

2. Significant Economic Benefits: Fast Payback, Long-Term Returns

In regions with high electricity costs — such as some African countries where industrial electricity prices exceed 2 yuan per kWh — the payback period for a solar air conditioner can be shortened to just 2–3 years. With a product design life of over 10 years, the subsequent operating cost is nearly zero. This makes it highly attractive for high-usage scenarios such as hotels, office spaces, and off-grid residences.

3. Off-Grid and Weak-Grid Adaptability

Unlike traditional air conditioners that rely on a stable power grid, our solar air conditioners support purely off-grid operation (when paired with energy storage) as well as wide-voltage grid access. This makes them the preferred cooling solution for areas without electricity — such as remote villages, communication base stations, and field camps.

Looking Ahead: Deepening Our Roots in Green Cooling, Making Coolness No Longer a Luxury

Although the three-day exhibition has come to an end, our company's exploration in the field of solar cooling has never stopped. Moving forward, we will continue to deepen our efforts in the R&D and manufacturing of solar air conditioners and DC refrigeration appliances. Through technological innovation, we aim to reduce users' electricity costs; with high-quality products, we will serve regions along the Belt and Road Initiative as well as other sun-rich areas around the globe — bringing affordable, reliable, and green cooling to more people living in power-deficient or electricity-scarce regions.
