Solar Panel - Mono PERC, Bifacial, and TOPCon
Solar technology has rapidly evolved, offering a range of panel types designed for greater efficiency, durability, and energy output. At Powertech Electro Mechanical Industries Pvt. Ltd. (PEMI), we specialize in advanced solar panel technologies that power everything from homes and offices to large-scale industries.
A solar panel is a device that captures sunlight and converts it into electricity using photovoltaic (PV) cells. These cells are made from semiconductor materials, usually silicon, which generate direct current (DC) electricity when exposed to sunlight. This electricity is then converted to alternating current (AC) via inverters for practical use in homes, industries, and the grid.
Types of Advanced Solar Panels:
Mono PERC Half-Cut Solar Panels
Bifacial Solar Panels
TOPCon (Tunnel Oxide Passivated Contact) Solar Panels
Mono PERC Half-Cut Solar Panels
Mono PERC (Passivated Emitter and Rear Cell) technology is an enhanced version of traditional monocrystalline solar panels. Half-cut cells mean each cell is split into two halves to reduce electrical resistance and power loss.
Key Features:
- Higher Efficiency – Typically 18%–21% efficiency, better than standard panels
- Half-Cut Cell Design – Minimizes resistive losses and improves shade tolerance
- Lower Temperature Coefficient – Performs better in high-temperature areas
- Compact & Powerful – More power output in smaller spaces
Ideal For:
- Residential rooftops
- Industrial & commercial spaces with limited space
- Areas with high daytime temperatures
Bifacial Solar Panels
Bifacial panels generate electricity from both the front and rear sides of the panel. While the front side absorbs direct sunlight, the back side captures reflected sunlight from the ground or nearby surfaces, enhancing overall energy yield.
Key Features:
- Up to 15% More Energy – Thanks to dual-side power generation
- Durable Glass-Glass Structure – Increases panel lifespan
- More Output per Square Foot – Excellent for utility and ground-mounted setups
- High ROI – Especially when installed over reflective surfaces like white concrete or sand
Ideal For:
- Solar farms
- Industrial rooftops
- Ground-mounted solar installations
- Carports and open parking lots
TOPCon (Tunnel Oxide Passivated Contact) Solar Panels
TOPCon panels represent the latest innovation in PV technology. They use a thin tunnel oxide layer and advanced contact design to minimize recombination loss and increase efficiency even further than PERC or Bifacial panels.
Key Features:
- Ultra-High Efficiency – Exceeds 22% in lab and >21% in real-world installations
- Excellent Low-Light Performance – Generates more power on cloudy days and mornings
- Longer Life Span – Lower degradation rates than traditional panels
- Great ROI – Ideal for large-scale commercial projects seeking fast payback
Ideal For:
- Utility-scale solar farms
- High-efficiency commercial installations
- Projects with limited space but high energy demands
