Introduction

Bifacial solar panels represent an advanced evolution in photovoltaic technology. Unlike traditional monofacial panels that capture sunlight only from one side, bifacial panels harvest solar energy from both sides, offering various performance and efficiency benefits. This article outlines these benefits, backed by numerical analyses, and looks at solutions provided by Tongyao company.

Benefits of Bifacial Solar Panels

Increased Energy Yield

Bifacial panels can increase energy output by capturing sunlight reflected from the ground and surrounding surfaces. On average, they can generate up to 30% more energy than monofacial panels, depending on the installation environment and conditions.

Enhanced Efficiency

The efficiency of bifacial panels typically ranges between 20% to 22%. This is higher than many conventional solar panels due to the additional energy captured from the rear side, optimizing space utility.

Durability and Longevity

Bifacial panels are often built with double glass instead of a backsheet, enhancing their durability. This construction minimizes the risk of micro-cracks and other damages, extending the lifespan beyond the typical 25-30 years of standard panels.

Reduced Levelized Cost of Energy (LCOE)

The increased energy output and efficiency result in a reduced Levelized Cost of Energy, making bifacial technology economically advantageous in the long term. The average LCOE can be reduced by about 5-10% compared to conventional panels.

Improved Performance in Diffuse Light Conditions

Bifacial panels perform better in diffuse light conditions, such as cloudy or overcast days, due to their ability to capture light from multiple angles. This adaptability leads to more consistent energy production.

Numerical Analysis of Bifacial Panels

To understand the impact of bifacial panels, consider a 100 kW installation:

• Monofacial Panel Output: Generates about 150,000 kWh per year.
• Bifacial Panel Output: Generates approximately 195,000 kWh per year, showing a 30% increase.

The increased output reduces the payback period by about 2-3 years, significantly impacting the return on investment (ROI).
