FAQs

Q1: Which brand offers the best value for money in 2025?

For residential installations, Canadian Solar's TOPHiKu6 and Jinko's Tiger Neo series offer excellent efficiency-to-price ratios with proven reliability.

Q2: Do higher efficiency panels justify the extra cost?

Yes, if roof space is limited. A 22% efficient panel generates 15-20% more power than a 19% panel in the same area, often justifying a 10-15% price premium.

Q3: How important is the manufacturer's warranty?

Critical for long-term investment protection. Prefer manufacturers with strong financial ratings (Canadian Solar, Trina, Jinko, Adani) who can honour 25-30 year commitments.

Q4: Should I choose Indian brands over international ones?

Indian brands (Vikram, Waaree, Adani) offer advantages including DCR compliance, faster service, local manufacturing support, and often better pricing. International brands excel in cutting-edge technology and global track records.

Q5: What degradation rate should I expect?

Premium N-type panels: 0.25-0.4% annually (REC, SunPower, Jinko Tiger Neo) Standard Mono PERC: 0.5-0.7% annually After 25 years, expect 84-92% of original capacity depending on technology.

Q6: How do Chennai's climate conditions affect panel selection?

Chennai's hot, humid climate with seasonal dust requires:

• Low temperature coefficient panels (N-type preferred)

• Regular cleaning schedules

• Corrosion-resistant mounting (especially near coast)

• Panels with good low-light performance for monsoon months

Q7: Can I mix different brands in one installation?

Not recommended. Different brands have varying electrical characteristics, potentially causing power losses and warranty complications.

Q8: What's the typical lifespan beyond warranty period?

Quality panels continue producing at 70- 80% capacity for 30-35 years, though warranties typically cover 25-30 years.
