The Sunlike Solar SERIES 5 has been designed to maximize energy yield under real-world operating conditions, even when the roof is not perfectly sunlit or the installation operates at varying temperatures. The use of N-type cells in the TOPCon technology reduces typical power losses over time and improves production stability, which translates into more predictable benefits for both consumers and businesses. The modules utilize a half-cut architecture and multi-busbar connections, allowing them to better handle partial shading and microcracks, while also distributing the current more evenly.

Bifacial variants further allow for the utilization of reflected light from the ground, which is particularly beneficial on bright roofs, ground-mounted structures, and carport installations. SERIES 5 is suitable for both residential and commercial applications, where high power density, durability, and aesthetics (e.g., full black versions) are important. Compared to many panels based on older P-type cells, this series focuses on higher resistance to degradation and more stable performance over the years.

Common questions

6 answered
What warranty does the Sunlike Solar SERIES 5 come with?
The Sunlike Solar SERIES 5 is backed by two separate warranties: a 12-year product warranty covering manufacturing defects and mechanical damage, and a 30-year linear power output warranty. This level of long-term coverage is made credible by the N-type TOPCon cell technology, which degrades more slowly than older P-type cells, ensuring the power guarantee holds real value over the module's lifespan.
Do Sunlike Solar SERIES 5 panels perform well in hot summer conditions?
Yes. The N-type TOPCon cells in SERIES 5 have a temperature coefficient of approximately -0.31%/°C, which is better than typical PERC modules at around -0.38%/°C. This means the panel loses less output as cell temperature rises on hot days, directly translating into higher annual energy yield compared to older P-type technology in warm climates.
How does the Sunlike Solar SERIES 5 differ from older PERC-based modules?
SERIES 5 uses N-type TOPCon cells, which are immune to Light-Induced Degradation (LID) and LeTID — issues common in P-type PERC panels. In practice, this means slower power loss over time (approximately 0.4%/year vs. 0.6–0.8% for PERC) and more stable output throughout the full 30-year warranty period. The half-cut cell architecture and multi-busbar interconnections further improve resistance to partial shading and microcracks.
Will Sunlike Solar SERIES 5 panels hold up with partial shading from a chimney or dormers?
Yes. The half-cut cell architecture and multi-busbar design used in SERIES 5 make it more resilient to partial shading than conventional full-cell modules. When part of the module is shaded, power losses are limited to the shaded area rather than the entire string. For installations with significant or consistent shading, pairing the panels with power optimizers or microinverters is also worth considering.
How many Sunlike Solar SERIES 5 panels do I need for a 10 kWp system?
The top variant in the SERIES 5 lineup reaches 600 Wp. At that power rating, a 10 kWp system requires only 17 modules — fewer components and connections compared to older 400–450 Wp panels. This high power density is especially valuable when roof space is limited or when maximizing energy output within a constrained installation area.
Are Sunlike Solar SERIES 5 panels bifacial?
The standard SERIES 5 configuration is not bifacial — only the front side of the module is active. Sunlike Solar does offer bifacial variants within its broader product range, but this version of the series harvests energy solely from direct irradiance on the front surface. This keeps installation straightforward and makes the module well suited to conventional pitched-roof mounting without the need for special racking to allow rear-side light access.
