The Ultimate Guide to Choosing Solar Panels for Your Home

🌞 Step 1: Understand Panel Types

• Monocrystalline panels: High efficiency (19–21%), compact size, best for limited roof space.
• Polycrystalline panels: Affordable, slightly lower efficiency (16–18%), good for larger rooftops.
• Thin-film panels: Lightweight, flexible, lower efficiency, and suitable for special applications.
• Advanced panels: TOPCon (21–23%) and HJT (22–24%) offer premium performance in hot or low-light conditions.

⚡ Step 2: Assess Your Home’s Solar Potential

• Roof orientation: South-facing roofs in India maximize sunlight.
• Shading analysis: Avoid trees or nearby buildings blocking sunlight.
• Available space: Calculate how many panels fit based on your daily kWh needs.

💰 Step 3: Cost and Subsidies

• Panel costs: ₹25,000–₹40,000 per kW, depending on type and brand.
• Government subsidies: PM Surya Ghar offers up to a 60% subsidy for rooftop solar.
• Financing options: Green loans, EMIs, and PPAs reduce the upfront burden.

🛠️ Step 4: Choose a Trusted Installer

• Certified installers: Ensure MNRE-approved vendors for subsidy eligibility.
• Warranty terms: Panels typically carry 25-year performance warranties.
• After-sales service: Check for local support and monitoring apps.

🚧 Common Mistakes to Avoid

• Ignoring inverter compatibility: Match panel capacity with inverter specs.
• Skipping maintenance: Clean panels regularly for optimal performance.
• Overlooking shading: Even partial shade can reduce output significantly.
