What are the advantages of bifacial solar panels? 

 The core competitiveness of the photovoltaic industry is that the cost of electricity per kilowatt hour is low enough. The key factor affecting the cost of electricity per kilowatt hour is the technical level of photovoltaic modules, because the initial investment of solar panels in the system accounts for a large proportion, which directly affects the power generation and system efficiency. Because of this, many photovoltaic power plants have begun to choose bifacial solar panels. What are the advantages of bifacial modules?

Double Sided Solar Panel

Usually the solar cells we see are single-sided solar cells, which can well accept direct sunlight and convert light energy into electricity. However, they can't do anything about some reflected sunlight. To take advantage of the reflected sunlight, double-sided solar panels must be used.

Different from the opaque back of conventional photovoltaic modules, the back of double-sided solar panels is encapsulated with glass. In addition to the normal power generation on the front, the back can also receive scattered light and reflected light from the environment to generate electricity, even in the sun. Due to the direct sunlight at sunrise or sunset, the double-sided module can generate more energy than the traditional single-sided module, so the double-sided module has a higher comprehensive power generation efficiency.

Advantages of Bifacial Solar Panels

A recent study by Singapore scientists found that the combination of double-sided solar panels and photovoltaic tracking support systems can increase power generation efficiency by 35%, and the average electricity price can be reduced by 16%. In order to maximize the power generation benefit in a limited space, recent studies have mentioned the advantages of bifacial solar energy. This kind of module with solar cells installed on both sides, in addition to the front cell can absorb sunlight, the back module can also absorb the ground reflected light and diffuse light, which can greatly improve the efficiency of solar power generation. At present, more and more power stations have begun to adopt double-sided solar technology. In countries with high latitudes, such as Europe and Japan, where it is prone to snow, the modules on the back can absorb the reflection of snow on the ground and increase power generation. Recent studies have also pointed out that bifacial solar energy can increase power generation efficiency by 15% to 20%.

How much is the power generation efficiency improved?

But despite this, the cost of bifacial solar panels is still very high at present, but the benefits it brings are also very considerable. The double-sided design enables the solar panel to receive an additional 15%~20% more energy, and placing it on some highly reflective surfaces can also effectively increase the utilization of reflected sunlight. If the price of bifacial solar panels can slide to an acceptable level, then it will certainly become a strong competitor in the renewable energy market.
