Previously, the standard was single-sided modules that work only from the front side. Now it is more profitable to choose double-sided panels that produce more energy by using reflected light. Let's figure out what is the difference between these types of panels and why double-sided panels are more efficient.
10–30% More Energy Thanks to Reflected Light
Double-sided panels generate electricity not only from the front, but also from the back, catching reflected light (albedo). This allows you to get 10–30% more energy depending on the surface under the panels and the height of their installation.
The Price Is Almost the Same, the Quality Is Higher
Today, the market is massively switching to double-sided modules: they cost a little more than single-sided ones, but have much better characteristics. The production of single-sided panels is gradually being phased out.
Longer Service Life
Double-sided panels have a warranty of up to 30 years, single-sided ones — 25. In addition, they degrade more slowly: 0.4% per year versus 0.55% for conventional modules. This means stable operation for decades.
Reliable Construction
Such panels are usually made in a glass-glass format. This makes them resistant to moisture, hail, corrosion, and mechanical damage. They also work better in the heat.
Better Performance in Different Weather Conditions
Double-sided modules are ideally combined with solar trackers and vertical structures (for example, solar fences or carports). They provide an increase in generation in the morning, evening, and even in cloudy weather, better capturing scattered light.
Lower System Costs and Higher Economic Efficiency
Thanks to higher efficiency, fewer panels are needed for the same power. This means savings on installation, cables, and labor. As a result, the cost of energy produced is lower in the long run.
