What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.260 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

According to our database: Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE has higher module efficiency (24.25% vs 24.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Heckert Solar ZEUS 3.0+ 108 490WP and Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE?
Heckert Solar ZEUS 3.0+ 108 490WP has a module efficiency of 24.00%, while Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE is 24.25%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Heckert Solar ZEUS 3.0+ 108 490WP use vs Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE?
Heckert Solar ZEUS 3.0+ 108 490WP uses Back Contact cells; Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE uses Back Contact. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Heckert Solar ZEUS 3.0+ 108 490WP and Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE?
Heckert Solar ZEUS 3.0+ 108 490WP has a 30 years power warranty; Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE has a 30 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.
Are Heckert Solar ZEUS 3.0+ 108 490WP and Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE bifacial panels?
Both Heckert Solar ZEUS 3.0+ 108 490WP and Heckert Solar ZEUS 3.0 108 495WP PERFORMANCE are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
