Investing in solar energy is one of the smartest decisions homeowners and businesses in Bangalore can make today. With rising electricity bills, climate change, and government subsidies, solar power is no longer a luxury—it’s a necessity.
But here’s the thing: not all solar panel systems are created equal. And if you’re new to solar, navigating the options can feel overwhelming.
At Pai Power Solutions, we’ve helped hundreds of customers make the right solar choices. Based on our experience, here are the top 5 things you must check before buying a solar panel system in Bangalore.
☀️ 1. Solar Panel Efficiency & Type
The most important component of your solar system is the solar panel itself. Its job is to absorb sunlight and convert it into usable electricity.
🔍 What to Check:
- Efficiency: This refers to how much sunlight your panel can convert into electricity. Most panels range from 15% to 22% efficiency. Higher efficiency = more power from less space.
- Type of Panels:
- Monocrystalline (Mono): High efficiency, long life, sleeker look. Best suited for limited rooftop space.
- Polycrystalline (Poly): More affordable, slightly lower efficiency. Suitable if space is not a constraint.
- Thin-Film: Lightweight and flexible, but less efficient. Rarely used for residential projects.
✅ Pai Power Tip:
We recommend Tier-1 Monocrystalline panels for most Bangalore homes due to their superior performance, even in cloudy weather.
⚙️ 2. Inverter Quality & Technology
Your solar panels generate DC (Direct Current) power, but your home uses AC (Alternating Current). That’s where the inverter comes in—it converts DC to AC and ensures smooth power flow.
🔍 What to Check:
- Inverter Type:
- String Inverters: Common and cost-effective. Suitable for clear, unobstructed rooftops.
- Microinverters: Installed with each panel. More expensive but ideal when there’s partial shade or panels face multiple directions.
- Hybrid Inverters: Combine solar and battery input. Ideal if you want battery backup for power cuts.
- Brand Reputation: Choose inverters from trusted manufacturers with proven performance and after-sales service.
- Warranty: Look for at least 5–10 years warranty.
✅ Pai Power Tip:
We offer SMA, Fronius, and Growatt inverters—global leaders known for durability and smart features like app-based monitoring.
🧾 3. System Size Based on Your Needs
Many customers make the mistake of either under-sizing or over-sizing their solar system. The right capacity depends on your monthly electricity usage, rooftop space, and budget.
🔍 How to Calculate:
Here’s a quick reference:
| Monthly Bill (₹) | Recommended System Size |
|---|---|
| ₹1,500 – ₹2,500 | 1.5 kW – 2 kW |
| ₹3,000 – ₹4,500 | 3 kW – 4 kW |
| ₹5,000+ | 5 kW and above |
Also consider future usage (e.g., if you plan to add an EV or AC later) when deciding system size.
✅ Pai Power Tip:
We offer site surveys to evaluate your roof and calculate the most efficient solar setup for your home or business.
📄 4. Warranties, Durability & Maintenance
A solar system is a long-term investment, expected to last 20–25 years. That’s why it’s crucial to check for proper warranties and durability features.
🔍 What to Check:
- Performance Warranty: Panels should come with a 25-year performance guarantee (usually 80–85% output retention).
- Product Warranty: Typically 10–12 years for panels, 5–10 years for inverters.
- Durability: Panels should be certified for wind, dust, and weather resistance—important in Bangalore’s varied climate.
- Support & AMC: Does your installer offer Annual Maintenance Contracts?
✅ Pai Power Tip:
All our solar panels and inverters come with genuine warranty certificates, and we provide dedicated AMC packages for long-term peace of mind.
📋 5. Subsidies, Net Metering & Installer Credentials
Many customers are unaware of the benefits they are eligible for—and end up missing out.
🔍 Government Subsidies:
Under the Rooftop Solar Programme Phase II (MNRE), homeowners can get:
- Up to 40% subsidy for systems up to 3 kW
- 20% subsidy for 4–10 kW systems
Subsidies are transferred directly to your account, but only when you go through a registered channel partner like Pai Power Solutions.
🔍 Net Metering:
With BESCOM net metering, you can:
- Export extra power to the grid
- Get credits in your monthly bill
- Reduce payback period to 4–5 years
🔍 Installer Checklist:
- MNRE-registered vendor
- Proven project portfolio
- End-to-end services (survey, approval, installation, maintenance)
✅ Pai Power Tip:
We handle all documentation, subsidy application, and BESCOM approvals—so you can relax while we do the work.
