The SKT680-700M12-132D5 solar panel series is an advanced solution based on M12 large-format silicon cells measuring 210 mm, which sets new efficiency standards in large-scale installations. The use of a bifacial double glass design allows for efficient energy generation from both sides of the module, significantly increasing yield in difficult ground conditions and on surfaces with high light reflectance. Thanks to the use of half-cut cell technology and multi-busbar connections, these modules minimize resistive losses and demonstrate excellent resistance to micro-cracks. For investors, the key benefit is BOS system cost optimization, as the high unit power of up to 700W allows for the installation of fewer structures and less cabling while maintaining the target power plant capacity. This solution effectively addresses the problem of limited space, offering the highest power density while maintaining a favorable temperature coefficient. This series is primarily dedicated to commercial solar farms and large industrial installations, where the priority is maximizing return on investment and long-term component reliability. It is distinguished from market competition by exceptional stability of operating parameters and reduced degradation, guaranteeing trouble-free and predictable power production for many years.

Common questions

6 answered
What warranty does the Sunket SKT680~700M12-132D5 series come with?
The SKT680~700M12-132D5 series carries a 15-year product warranty covering material and manufacturing defects. Sunket also provides a 30-year linear power warranty guaranteeing a minimum of 88% of rated output after three full decades of operation. This is one of the longer warranty schedules available in the commercial large-format module segment.
What is HJT technology used in the SKT680~700M12-132D5, and how does it compare to PERC?
HJT (Heterojunction Technology) is an N-type cell architecture that sandwiches a crystalline silicon wafer between thin amorphous silicon layers. Compared to standard PERC, it delivers higher module efficiency — 21.9–22.5% for this series — a better temperature coefficient that reduces power losses on hot days, and the complete absence of LID (Light Induced Degradation). The result is more stable and predictable energy output throughout the module's service life.
Do the SKT680~700M12-132D5 panels perform well during summer heat?
Yes. HJT technology offers a more favorable temperature coefficient than conventional PERC cells, meaning the SKT680~700M12-132D5 loses less output per degree Celsius of cell temperature rise. For commercial solar farms across Central Europe, this translates into higher energy yield during peak summer months and directly contributes to a lower LCOE over the project lifetime.
What advantage does the bifacial double glass construction of the SKT680~700M12-132D5 provide?
The bifacial design allows the module's rear side to harvest irradiance reflected from the ground surface. On ground-mounted installations with light-colored gravel or snow cover, rear-side power gain typically ranges from 5 to 15%. The dual-glass encapsulation — replacing a conventional backsheet — also improves resistance to moisture ingress, ammonia, and UV degradation, extending real-world service life beyond the stated 30-year power warranty period.
Is the SKT680~700M12-132D5 series suitable for residential rooftop installations?
The SKT680~700M12-132D5 is engineered for commercial solar farms and large industrial installations. At 2384 × 1303 mm and approximately 38.7 kg per module, on-roof handling is logistically demanding and may require reinforced racking structures not found in standard residential systems. Homeowners planning a prosumer installation would be better served by a smaller module from Sunket's lineup or another manufacturer.
What module efficiency does the Sunket SKT700M12-132D5 achieve, and how does it reduce BoS costs?
The SKT700M12-132D5 modules achieve efficiency in the 21.9–22.5% range, placing them among the top-tier commercially available large-format modules. With peak power up to 700W, fewer modules, mounting structures, and cable runs are needed to reach a target plant capacity. The resulting BoS cost optimization is especially significant for investors developing utility-scale projects above 1 MWp.
