With its abundant sunlight and growing commitment to renewable energy, the Philippines is rapidly expanding its solar power sector with various innovations and opportunities.
One such innovation gaining traction is bifacial solar modules. It is a technology that allows the solar panel to absorb sunlight from both the front and back surfaces. Unlike monofacial panels that rely solely on direct sunlight, bifacial modules utilize reflected light from surfaces like rooftops, water, or the ground to boost energy production.
Understanding Bifacial Solar Modules
Bifacial solar modules harness light from both the front and back sides due to their dual approach tilt. This enables the modules to make use of the surroundings’ direct sunlight and any light that can be reflected off buildings, which further increases their energy production.
Bifacial solar panels can generate up to 30% more energy than monofacial ones. With the government of the Philippines encouraging solar usage, along with significant investments in renewable energy, these panels are becoming increasingly attractive for large-scale solar farms, residences, and rooftops.
How Do Bifacial Solar Modules Work?
The functionality of bifacial solar modules is rooted in their distinctive design and installation:
1. Dual-Sided Photovoltaic Cells
Both surfaces of the panel are equipped with photovoltaic cells that convert light into electricity. The rear side captures albedo light, sunlight reflected off surfaces such as the ground, water bodies, or nearby edifices.
2. Transparent Backing Materials
Unlike the opaque backing in monofacial panels, bifacial modules utilize transparent materials like glass. This transparency permits light to penetrate and reach the rear cells.
3. Strategic Installation
To maximize efficiency, bifacial panels are often mounted with a clearance between the panel and the installation surface. This setup facilitates the reflection of light onto the rear side. Additionally, adjusting the panels’ tilt can optimize exposure to both direct and reflected sunlight.
Advantages of Bifacial Solar Modules in the Philippines
Bifacial solar modules offer several benefits, particularly suited to the Philippine environment:
1. Enhanced Energy Yield
By capturing light on both sides, these panels can generate up to 30% more energy than traditional monofacial panels. This increase is especially advantageous in regions with high surface reflectivity, such as coastal areas with sandy terrains.
2. Improved Efficiency
The capability to utilize reflected light ensures that bifacial modules maintain higher efficiency levels throughout the day, even when the sun is at a lower angle.
3. Durability and Longevity
Many bifacial panels are constructed with glass on both sides, offering robust protection against environmental factors like typhoons and humidity prevalent in the Philippines. This design can lead to a longer lifespan and potentially lower maintenance costs.
4. Aesthetic Integration
With their sleek, frameless designs, bifacial modules can be seamlessly integrated into modern architectural projects, enhancing the visual appeal of urban developments.
Applications of Bifacial Solar Modules in the Philippines
The versatility of bifacial solar modules makes them ideal for various applications across the Philippines:
- Ground-Mounted Systems: In open fields or solar farms, elevating bifacial panels allows them to capture reflected light from the ground, boosting overall energy production.
- Rooftop Installations: Flat rooftops, typical in urban Philippine settings, can benefit from bifacial modules, especially when the roof surface is reflective.
- Building-Integrated Photovoltaics (BIPV): Bifacial panels can be incorporated into building facades, balconies, or canopies, making efficient use of available space while enhancing the building’s aesthetics.
- Floating Solar Farms: Given the Philippines’ numerous water bodies, installing bifacial panels on floating platforms can capitalize on water surface reflectivity, leading to increased energy generation.
Growing Popularity of Bifacial Solar Modules in the Philippines
Several factors contribute to the rising adoption of bifacial solar technology in the country:
- Government Initiatives: The Philippine government aims to increase the share of renewable energy in its power mix to 35% by 2030 and 50% by 2040. This ambitious target has spurred interest in advanced solar technologies, including bifacial modules.
- Collaborative Investments: Significant partnerships, such as the $15 billion agreement between the Philippines and the UAE’s Masdar to develop renewable energy projects, underscore the nation’s commitment to expanding its solar infrastructure.
- Technological Advancements: Continuous improvements in materials and design have bolstered the performance and reliability of bifacial modules, making them a viable option for diverse environments across the archipelago.
- Market Availability: Reputable suppliers, including PHILERGY, offer high-quality bifacial solar panels tailored for the Philippine market, ensuring accessibility for both residential and commercial installations.
Considerations for Implementing Bifacial Solar Modules in the Philippines
While bifacial modules present numerous advantages, it’s essential to consider specific factors to maximize their potential in the Philippine setting:
- Site Reflectivity: The amount of reflected light significantly impacts performance. Surfaces like light-colored roofs or sandy grounds can enhance reflectivity.
- Installation Parameters: Elevating the panels and adjusting the tilt can optimize the capture of reflected light. However, these adjustments must account for structural integrity, especially in typhoon-prone areas.
- Shading Concerns: Objects casting shadows on either side of the panel can reduce efficiency. Thorough site assessment and planning are crucial to minimize shading, particularly in densely populated urban areas.
- Economic Evaluation: While prices have decreased, bifacial modules may still have higher upfront costs than monofacial panels. It’s important to assess whether the increased energy production justifies the initial investment for your specific application.
