Key technical and buying factors to check
When you compare brands and models, study these items carefully.
Panel efficiency
Higher efficiency panels make more power per square foot.
This is vital for small roofs.
Temperature coefficient
This measures power loss in heat.
Lower loss numbers are better for hot places.
Power tolerance and degradation
Check the positive tolerance and annual degradation rate.
A good panel keeps at least 80 to 85 percent output after 25 years.
Certifications and testing
Look for IEC and BIS certifications.
These show the panels meet global and Indian standards.
Warranty terms
There are two key warranties.
Product warranty covers physical defects.
Performance warranty guarantees output after a set period.
Service network and claims process
A strong local service network shortens repair time.
Ask who handles warranty claims and where to call.
ALMM and policy considerations
Some government tenders and schemes refer to the Approved List of Models and Manufacturers.
If you plan to use specific government subsidies for rooftop solar, check whether the model is eligible.
Expected price trends and panel sizes in 2025
Panel wattages for homes commonly range from 350 W to 600 W.
High watt modules help reduce roof space need.
Retail per watt prices vary with technology and brand.
Domestic manufacturing expansion in 2024 and 2025 helped supply.
This reduced some price pressure and shortened lead times in many regions. The Times of India
Always ask for an itemized quote.
The quote should list panel model, inverter model, mounting, wiring, labour, and GST.
Compare at least three quotes before you decide.
Installation, maintenance and life expectancy
Installation quality matters as much as the brand.
A skilled installer ensures correct tilt, wiring and earthing.
Poor installation can reduce output and cause safety issues.
Maintenance is low.
Panels need cleaning occasionally.
Inverters need periodic checks.
Batteries need maintenance if you have them.
A good panel will work efficiently for 20 to 25 years.
Keep serial numbers and warranty documents safe.
