Sunlike Solar panels from the SKT490-510M12-108D4 series are an advanced solution based on N-Type TOPCon cells, which provide significantly higher efficiency compared to older technologies. Thanks to the use of bifacial technology, i.e., double-sided energy generation, these modules maximize yield per square meter of surface area, which is crucial when installation space is limited. The use of large M12 silicon wafers allows for achieving high unit power while maintaining the compact dimensions of the 108-cell design. This solves the problem of mounting structure costs, as a smaller number of modules generates the same system power. This series stands out with a low temperature coefficient, which makes the panels operate stably even on hot days, minimizing energy losses. The product is dedicated to both prosumer and commercial installations, where long-term durability and resistance to LID and LeTID degradation matter. Compared to the competition, Sunlike Solar offers an excellent price-to-performance ratio, using double tempered glass, which guarantees excellent mechanical protection and resistance to harsh weather conditions. It is an investment in energy stability and a faster return on investment.

Common questions

6 answered
Is the Sunlike Solar SKT490-510M12-108D4 series still available for purchase?
The SKT490-510M12-108D4 series has been discontinued and is being replaced by the manufacturer's newer models. Units may still be available from distributors as remaining stock, though quantities are limited. For larger installations, it's worth confirming availability of the required number of modules with matching batch numbers from your supplier beforehand.
How does the N-type TOPCon technology in this series differ from classic PERC panels?
The N-type TOPCon cells used in the SKT490-510M12-108D4 series offer higher conversion efficiency and significantly lower degradation over time than older P-type PERC cells. An additional tunnel oxide layer reduces electron recombination, resulting in higher energy yield, especially under high temperature and irradiance, plus longer real-world system lifespan.
How much extra energy do I really gain from the bifacial technology in these panels?
Dual-side generation in the bifacial SKT490-510M12-108D4 series can yield an additional 5-20% energy from the rear side, depending on ground albedo, mounting height, and tilt angle. Best results are achieved over bright, reflective surfaces such as gravel or white roofing, and with ground-mount structures that provide sufficient clearance beneath the module.
What warranty comes with the Sunlike Solar SKT490-510M12-108D4 series?
The manufacturer offers a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means that even after three decades of operation, the module should retain a guaranteed, high percentage of its original rated power, making this series a solid long-term investment.
Do the large M12 wafers and 108-cell layout make this panel too heavy or large for a pitched roof?
Modules built on M12 wafers in a 108-cell configuration have a larger surface area and higher power output than standard panels, meaning fewer modules and less mounting hardware are needed to reach the same system power. Before installing on a pitched roof, it's important to check roof load capacity and module dimensions, as the larger size may require extra care during transport and mounting.
How does the SKT490-510M12-108D4 series perform in summer heat on a hot roof?
This series features a low temperature coefficient, typical of N-type TOPCon cells, which limits power loss during heat waves compared to older P-type technologies. As a result, the panels deliver a more stable energy yield on hot summer days, when the module surface temperature on a roof can significantly exceed ambient air temperature.
