What Are Polycrystalline Solar Panels?
Polycrystalline solar panels are made from multiple silicon crystals melted together, giving them a distinctive blue, speckled appearance. While slightly less efficient than monocrystalline panels, they are more cost-effective, making them a popular choice for budget-conscious homeowners and businesses in Telangana and Andhra Pradesh. With efficiencies of 15–18%, polycrystalline panels are ideal for larger rooftops or areas with ample sunlight, converting sunlight into electricity for on-grid or off-grid solar systems.
Note: Unilux Solar currently offers on-grid and hybrid solar systems using polycrystalline panels and is exploring their integration into other applications. The information below reflects standard market practices in Telangana and Andhra Pradesh as of September 2025.

How Do Polycrystalline Solar Panels Work?
Polycrystalline solar panels generate electricity through the photovoltaic effect. Here’s a simple breakdown:
- Sunlight Absorption: Solar cells, made from multiple silicon crystals, absorb sunlight (photons), exciting electrons to create a direct current (DC).
- Power Optimization: While less efficient than monocrystalline panels, modern polycrystalline panels may include technologies like half-cut cells to improve performance in partial shade.
- Power Aggregation: Panels are wired in series or parallel to optimize voltage and current, feeding into a combiner box for safety and monitoring.
- DC to AC Conversion: An inverter converts DC electricity into alternating current (AC) for household appliances or grid connection.
- 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.
Features of Polycrystalline Solar Panels
Polycrystalline panels are known for their unique characteristics:
- Cost-Effective: Lower production costs make them more affordable than monocrystalline panels (₹40–50/Wp vs. ₹50–70/Wp).
- Moderate Efficiency: 15–18% efficiency, suitable for larger rooftops in rural or semi-urban areas.
- Distinctive Appearance: Blue, speckled look due to multiple silicon crystals, less uniform than monocrystalline panels.
- Durability: Last 20–25 years with coatings to withstand coastal humidity and monsoons in Andhra Pradesh.
- Versatile Applications: Ideal for budget installations in homes, farms, or small businesses.
Components of a Polycrystalline Solar Panel System
A solar system using polycrystalline panels includes the following components, optimized for cost and reliability:
- Polycrystalline Panels: Multi-crystal silicon cells, sometimes with half-cut designs for improved performance.
- Inverter: Converts DC to AC power. Modern string or micro-inverters offer up to 97% efficiency and smart monitoring.
- Charge Controller (for off-grid systems): Uses Maximum Power Point Tracking (MPPT) to optimize battery charging and extend lifespan.
- Battery (for off-grid or hybrid systems): Lithium-ion batteries (8–12 years lifespan) or lead-acid (3–5 years) store excess energy.
- Mounting Structures: Pre-engineered, corrosion-resistant frames to secure panels at optimal angles, designed to withstand winds in coastal Andhra Pradesh.
- Accessories: Includes DC/AC cables, MC4 connectors, earthing strips, and lightning arresters for safety during Telangana’s monsoons.
- When Should You Use Polycrystalline Solar Panels?
Polycrystalline solar panels are ideal for various scenarios in Telangana and Andhra Pradesh:
- Budget-Conscious Homes: Perfect for households in Warangal, Guntur, or Rajahmundry looking for affordable solar solutions with ample roof space.
- Rural Areas: Ideal for farms in Srikakulam or Nalgonda, especially in off-grid setups with no grid access.
- Small Businesses: Suitable for shops or small factories in Telangana’s Medak or Andhra’s Kurnool, balancing cost and performance.
- Large Rooftops: Best for homes or complexes with sufficient space, where efficiency is less critical than cost.
- Eco-Conscious Households: Great for families aiming to reduce their carbon footprint on a budget.
For urban homes with reliable grid access, Unilux Solar recommends on-grid systems using polycrystalline panels for cost savings and subsidies. Off-grid systems are better for remote areas with frequent power outages.
Estimated Costs of Polycrystalline Solar Panel Systems in Telangana and Andhra Pradesh (2025)
The cost of a polycrystalline solar panel system is lower than monocrystalline systems due to simpler manufacturing. Below are approximate costs for 2025:
| System Capacity | On-Grid Cost (After Subsidies, ₹) | Off-Grid Cost (₹) |
| 2 kWp | 80,000–1,30,000 | 1,50,000–1,90,000 |
| 3 kWp | 90,000–1,40,000 | 2,30,000–2,80,000 |
