The Sunova TS-BGT66-G12 series (695-720 W) was designed with the goal of maximizing yield from large-scale installations, where every square meter of the structure and every hour of the installation team's work matters. These are bifacial modules in a glass-glass configuration, effectively utilizing reflected light from the ground as well, facilitating higher energy production without expanding the farm.

The key advantage is the N-type TOPCon cell technology - ensuring more stable performance over time and reduced susceptibility to typical initial losses, making the design stabilize over the long term. Additionally, the G12 format and the module architecture designed for high power density allow for reducing BOS costs and logistics in large volumes.

This series will excel primarily in utility-scale PV farms and projects, even in challenging environmental conditions, thanks to the high mechanical strength of the glass-glass construction, which genuinely reduces the risk of microcracks and claims. It is the choice for investors seeking predictable yields and longevity, rather than compromises.

Common questions

6 answered
What type of installation is the Sunova TS-BGT66-G12 series suited for?
The TS-BGT66-G12 series (695-720 W) is designed for large-scale PV farms and utility-scale projects, where high unit power and low cost per watt matter most. The large G12 format and glass-glass construction work best for ground-mount installations and large industrial rooftops, rather than typical residential pitched roofs.
How does a bifacial glass-glass panel differ from a standard glass-backsheet panel?
A bifacial glass-glass panel like the TS-BGT66-G12 generates energy from both sides of the module, capturing light reflected off the ground, roof, or albedo surface beneath the array, boosting yield by several percent or more without increasing the array's footprint. The glass-on-both-sides design, instead of a rear backsheet, also improves mechanical durability and extends module lifespan in harsh conditions.
What is N-type TOPCon technology and is it worth choosing?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces surface recombination losses and delivers more stable performance over the module's lifetime than older P-type PERC cells. In practice, this means lower initial power degradation and more predictable energy yield, which translates into a better return on investment for large utility projects over the long term.
What warranty comes with Sunova TS-BGT66-G12 panels?
Sunova offers a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the panel should still retain a significant share of its original rated power after 30 years, matching the best offers currently available for bifacial N-type modules.
Is Sunova a tier-1 manufacturer, and where are TS-BGT66-G12 panels made?
Sunova is not currently listed as a tier-1 manufacturer under the BloombergNEF classification, though it produces modules in China using modern N-type TOPCon technology. Lack of tier-1 status doesn't necessarily mean lower technical quality, but it's worth considering if project financing requires panels from that list.
Are bifacial glass-glass panels more resistant to microcracks?
Yes, the glass-glass construction used in the TS-BGT66-G12 series provides significantly higher mechanical rigidity than traditional glass-backsheet designs, meaningfully reducing the risk of cell microcracks during transport, installation, and operation in harsh climates. This results in fewer warranty claims and more predictable energy production throughout the 30-year power warranty period.
