When exploring solar energy, one of the first questions homeowners and businesses ask is, “What are the different solar PV modules types, and which one should I choose?“
Solar PV Modules Types (commonly called solar panels) are the building blocks of any solar power system. They come in various designs, materials, and efficiency levels, each suited to different needs and budgets.
This guide will break down the main types of solar PV modules, their costs, efficiency, benefits, and best use cases in India.
What Are Solar PV Modules?
Solar PV modules are devices made up of multiple photovoltaic cells that capture sunlight and convert it into electricity. These modules are connected to form arrays and can power everything from small homes to large industrial facilities.
If you’re planning to install a Solar Electric Panel for Home, understanding PV module types is essential for making the right investment.
Main Solar PV Modules Types
The most common solar PV modules types available in India include:
1. Monocrystalline Solar Modules
- These modules are constructed from a single silicon crystal.
- The modules offer a higher efficiency of 18–22%.
- It boasts a sleek black appearance.
- Perform well in limited space.
- Costlier than other types.
👉 Best for homeowners who want maximum efficiency in smaller rooftops.
2. Polycrystalline Solar Modules
- It’s made from multiple silicon crystals melted together.
- The modules have an efficiency of approximately 15-17%.
- Bluish hue.
- More affordable than monocrystalline.
- Requires more space to produce the same energy.
👉 Suitable for budget-conscious families in India with larger rooftop areas.
3. Thin-Film Solar Modules
- Made by depositing photovoltaic material on glass, metal, or plastic.
- Lightweight and flexible.
- Efficiency ranges from 10 to 13%.
- Perform better in high temperatures but need large installation space.
👉 Ideal for commercial spaces or ground-mounted projects where weight is a concern.
4. Bifacial Solar Modules
- Generate electricity from both sides (front and back).
- Higher power generation compared to traditional panels.
- Require reflective surfaces for best performance.
- More expensive upfront.
👉Great for solar power installation projects aiming for high ROI in the long run.
5. PERC (Passivated Emitter and Rear Cell) Modules
- A technology upgrade on monocrystalline and polycrystalline modules.
- By reflecting unabsorbed light back into the cell, these modules improve efficiency.
- The high performance of these modules is making them increasingly popular in India.
It is often included ino home solar installation cost estimates for urban buyers.
Comparing Solar PV Modules Types
When evaluating solar PV panels price in India, it’s important to weigh cost vs. efficiency.
- Monocrystalline = High cost, high efficiency.
- Polycrystalline: medium cost, medium efficiency.
- Thin-film = Low cost, lower efficiency.
- Bifacial = Premium cost, highest output in the right conditions.
Checking with local Solar Energy Contractors helps match your rooftop space, energy needs, and budget to the right module type.
Solar PV Modules Price in India (2025)
The Solar Energy Panels Price in India typically falls in this range:
- Polycrystalline: ₹22–₹28 per watt
- Monocrystalline PERC: ₹28–₹35 per watt
- Bifacial panels: ₹35–₹45 per watt
- Thin-film panels: ₹18–₹25 per watt
These costs may vary by supplier, brand, and subsidy availability.
For precise calculations, compare with solar PV panels price in India based on wattage and system size.
Installation and Technology Support
The process of installing solar depends not just on panels but also on:
- Inverters (convert DC to AC)
- Mounting structures (adjust panel tilt)
- Wiring and safety gear
- Net metering setup
Modern installers also use Drone Thermal Imaging to detect faulty cells and ensure panels work at full efficiency. Advanced Top Drone Service Providers in Chandigarh even offer aerial rooftop surveys to optimize design before installation.
Benefits of Choosing the Right Module Type
- Cost Savings: Reduce electricity bills by 70–90%.
- Government Subsidies: Save 30–40% on home solar installation cost.
- Energy Independence: Reduce reliance on grid power.
- Eco-Friendly: Contribute to India’s renewable energy goals.
- Long-Term ROI: Payback in 4–6 years, with 25 years of energy production.
