- ~21% efficiency — among the highest available for residential solar in India
- 2.5–3 units per panel per day — so this pack of 2 generates 5–6 units/day
- Excellent low-light performance — continues generating power even on cloudy or overcast days
- 27-year performance warranty — the longest in its class, giving you decades of guaranteed output
- 12 Bus Bar (12BB) technology — enhanced crack tolerance and reduced power loss
- Dual glass construction — superior durability against moisture, humidity, and mechanical stress

❓ Frequently Asked Questions
Q: What is the advantage of bifacial panels over standard panels?
A: Bifacial panels generate electricity from both the front and rear surfaces. The rear captures reflected sunlight from the roof or ground, adding 10–25% more energy output compared to standard mono panels of the same wattage.
Q: How many of these panels do I need for a 5 KW system?
A: You would need approximately 10 panels (5,400W ≈ 5 KW). This listing is for a pack of 2, so you would need 5 packs.
Q: Are these panels compatible with my existing inverter?
A: Yes, these panels are compatible with all standard MPPT solar inverters. Check that your inverter's input voltage range covers the panel's Voc of 49.61V when connecting in series.
Q: What does the 27-year warranty cover?
A: The 27-year performance warranty guarantees that the panels will produce at least 80% of their rated output after 27 years. Visit waaree.com for full warranty terms.
Q: Is installation included?
A: Panels are supplied only. Installation is by the consumer or a local solar installer. We provide technical guidance post-purchase.
Q: How long does delivery take?
A: Delivery typically takes 5–10 business days. Pan-India delivery available.
