What Are Modern Solar Panels?

Modern solar panels represent the latest advancements in photovoltaic (PV) technology, designed to maximize efficiency, durability, and energy output. These panels incorporate cutting-edge materials and designs, such as Passivated Emitter and Rear Cell (PERC), bifacial, half-cut cells, and Tunnel Oxide Passivated Contact (TOPCon), and HJT (Heterojunction Technology) to deliver superior performance compared to traditional panels. With efficiencies ranging from 19–25%, modern solar panels are ideal for the sunny climate of Telangana and Andhra Pradesh, powering homes, businesses, and farms in both on-grid and off-grid systems.

Note: Unilux Solar currently offers on-grid and hybrid solar systems using modern panels like monocrystalline PERC and is exploring other advanced technologies. The information below reflects standard market practices in Telangana and Andhra Pradesh as of September 2025.

 

How Do Modern Solar Panels Work?

Modern solar panels generate electricity through the photovoltaic effect, enhanced by advanced technologies. Here’s a simple breakdown:

1. Sunlight Absorption: Solar cells, typically made of high-purity silicon or thin-film materials, absorb sunlight, exciting electrons to create a direct current (DC).
2. Enhanced Efficiency: Technologies like PERC, bifacial, or TOPCon increase energy capture, even in low-light or high-temperature conditions.
3. Power Aggregation: Panels are wired in series or parallel to optimize voltage and current, feeding into a combiner box for safety and monitoring.
4. DC to AC Conversion: An inverter converts DC electricity into alternating current (AC) for household appliances or grid connection.
5. Energy Storage or Grid Feed: In off-grid systems, excess energy charges batteries via a charge controller. In on-grid systems, surplus power is fed to the grid, earning credits from your DISCOM.

 

Types of Modern Solar Panels

Modern solar panels include several advanced types, each suited for specific needs in Telangana and Andhra Pradesh:

1. Monocrystalline PERC Panels:
   1. Made from a single silicon crystal with Passivated Emitter and Rear Cell (PERC) technology.
   2. Efficiency: 20–23%.
   3. Best for: Urban homes in Hyderabad or Vijayawada with limited roof space.
2. Bifacial Panels:
   1. Capture sunlight on both sides, reflecting light from surfaces like rooftops or ground.
   2. Efficiency: 21–24%.
   3. Best for: Sunny rural areas like Warangal or Visakhapatnam with reflective surfaces.
3. Half-Cut Cell Panels:
   1. Cells are cut in half to reduce resistance and improve efficiency.
   2. Efficiency: 19–22%.
   3. Best for: Residential complexes in Guntur or Rajahmundry with partial shade.
4. TOPCon Panels:
   1. Use Tunnel Oxide Passivated Contact technology for enhanced efficiency.
   2. Efficiency: 22–25%.
   3. Best for: Industrial setups in Medak or Kurnool requiring high output.
5. HJT (Heterojunction Technology) Panels
   1. Combines monocrystalline silicon wafers with thin-film layers.
   2. Efficiency: 23–26%.
   3. Best for: High-end projects, premium housing, and commercial malls in Hyderabad/Amaravati.

 

Components of a Modern Solar Panel System

A modern solar panel system includes the following components, optimized for efficiency and durability:

1. Modern Solar Panels: Monocrystalline PERC, bifacial, or TOPCon panels for maximum energy output.
2. Inverter: Converts DC to AC power. Modern string or micro-inverters offer up to 98% efficiency and smart monitoring.
3. Charge Controller (for off-grid systems): Uses Maximum Power Point Tracking (MPPT) to optimize battery charging and extend lifespan.
4. Battery (for off-grid or hybrid systems): Lithium-ion batteries (8–12 years lifespan) or lead-acid (3–5 years) store excess energy.
5. Mounting Structures: Pre-engineered, corrosion-resistant frames to secure panels at optimal angles, designed to withstand winds in coastal Andhra Pradesh.
6. Accessories: Includes DC/AC cables, MC4 connectors, earthing strips, and lightning arresters for safety during Telangana’s monsoons.

 

When Should You Use Modern Solar Panels?

Modern solar panels are versatile and suited for various scenarios in Telangana and Andhra Pradesh:

1. Urban Homes: Monocrystalline PERC or half-cut panels are ideal for compact rooftops in Hyderabad or Vijayawada, maximizing output in limited space.
2. Rural Areas: Bifacial or thin-film panels suit farms in Warangal or Srikakulam, especially for off-grid setups with no grid access.
3. Residential Complexes: Half-cut or bifacial panels work well for multi-story buildings in Visakhapatnam or Guntur, handling partial shade.
4. Industrial Use: TOPCon panels are perfect for factories in Medak or Kurnool, where high output is critical.
5. Eco-Conscious Households: Ideal for families aiming to reduce their carbon footprint with sustainable energy.

For urban homes with reliable grid access, Unilux Solar recommends on-grid systems using modern panels for cost savings and subsidies. Off-grid systems are better for remote areas with frequent power outages.
