Pro Tips for Solar Buyers in India
Expert advice to maximize your rooftop solar investment
Optimize Roof Direction
South-facing roofs yield the highest generation in India. East/West roofs work but generate about 10-15% less power annually.
Verify Net Metering
Ensure your state electricity board (DISCOM) supports Net Metering so you get financial credit for excess power sent to the grid.
Panel Technology
Choose Monocrystalline Half-Cut panels for limited space—they perform significantly better in high temperatures and low light.
Regular Maintenance
Dust accumulation can drop efficiency by 15%. Wash panels every 2 weeks with soft water for maximum ROI.
Inverter Selection
String inverters are cost-effective, but if your roof experiences partial shading, Microinverters or DC Optimizers are crucial.
Understand Warranties
Differentiate between a 10-12 year ‘Product Warranty’ (for defects) and a 25-year ‘Performance Warranty’ (guarantees 80%+ output).
