Questions about this pairing
Which panel is better: Heckert Solar ZEUS 2.2-715 or Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE?
According to our database: Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE has higher module efficiency (24.00% vs 23.00%); Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE tolerates heat better (temp coeff -0.260%/°C vs -0.280%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Heckert Solar ZEUS 2.2-715 and Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE?
Heckert Solar ZEUS 2.2-715 has a module efficiency of 23.00%, while Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE is 24.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Heckert Solar ZEUS 2.2-715 use vs Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE?
Heckert Solar ZEUS 2.2-715 uses TOPCon cells; Heckert Solar ZEUS 3.0+ 108 490WP 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 2.2-715 and Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE?
Heckert Solar ZEUS 2.2-715 has a 30 years power warranty; Heckert Solar ZEUS 3.0+ 108 490WP 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 2.2-715 and Heckert Solar ZEUS 3.0+ 108 490WP PERFORMANCE bifacial panels?
Both Heckert Solar ZEUS 2.2-715 and Heckert Solar ZEUS 3.0+ 108 490WP 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.
