Waaree WSMD-540 vs Waaree WSMD-535

Q: Which panel is better: Waaree WSMD-540 or Waaree WSMD-535?

According to our database: Waaree WSMD-540 has higher module efficiency (20.98% vs 20.78%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Waaree WSMD-540 and Waaree WSMD-535?

Waaree WSMD-540 has a module efficiency of 20.98%, while Waaree WSMD-535 is 20.78%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Waaree WSMD-540 use vs Waaree WSMD-535?

Waaree WSMD-540 uses PERC cells; Waaree WSMD-535 uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Waaree WSMD-540 and Waaree WSMD-535?

Waaree WSMD-540 has a 27 years power warranty; Waaree WSMD-535 has a 27 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
