Series 6

Optimized Design. Lower LCOE. Superior Return.

First Solar Series 6 and Series 6 Plus photovoltaic (PV) modules set the industry benchmark for reliable energy production, optimized design and environmental performance.

Series 6

420 - 450 watts / up to 18.2% efficiency

Superior temperature coefficient, spectral response and shading behavior means more energy per watt vs. conventional c-Si modules
Innovative under-mount frame with SpeedSlots enable the industry’s fastest installation times and lowest mounting hardware costs
Dual junction box design reduces wire management complexity and cost
Best-in-class durability and reliability
No power loss from LiD or LeTID
Immune to and warranted against power loss from cell cracking
Industry’s best environmental profile with the lowest carbon and water footprint, and fastest energy payback

Series 6 Plus

430 - 460 watts / up to 18.3% efficiency

Includes all of the advantages of Series 6
Larger form factor provides more watts per module, with minimal impact to structure design
Enhanced BOS savings through fewer connections and less mounting hardware per watt
Series 6 Plus will be available in two product variants that are easily matched to structure zones:

Interior array modules - a lighter load-compliant module that will occupy the interior rows of an array. The reduced weight enables faster install velocity
Exterior array modules - a higher load module that ensures an appropriately robust perimeter for an array

Overall lower LCOE for a competitive return on investment
