Middle of its segment, modest efficiency
The Kyocera KK275P-3CD3CG solar panel series is the answer to the needs of investors seeking maximum durability in rooftop and ground-mounted installations. The use of patented polycrystalline cell technology makes these modules characterized by exceptional operational stability even in varying sunlight conditions, which directly translates into predictable energy gains. The design based on three-busbar photovoltaic cells minimizes the risk of micro-cracks, solving the common problem of mechanical panel degradation in the harsh Polish climate. This solution is dedicated primarily to demanding commercial systems and households, where maintaining high efficiency for decades, and not just in the first years of operation, is key. What distinguishes the KK275P-3CD3CG series from the competition is total vertical production integration - from raw silicon to the finished module - which guarantees unprecedented repeatability of technical parameters for every unit. Thanks to the use of a reinforced frame and advanced insulating materials, these panels offer increased resistance to the PID phenomenon and extreme weather loads, such as strong wind or heavy snow. By choosing this series, the user opts for Japanese technical culture, which effectively eliminates the risk of a premature drop in installation performance.
Ranking
Signals from the data
Residential and commercial.
Tight roof space and roofs where every square metre has to count.
Bottom 24% of the 175-375 W band, against a median of 18.40%.
Bottom 24% of the 175-375 W band, against a median of 183.4.
Kyocera manufactures from raw silicon through to the finished module in-house, reducing unit-to-unit parameter variance - a rare capability among polycrystalline module makers in the 275 Wp power class.
The manufacturer guarantees a linear power output over 25 years, a premium standard for the polycrystalline segment and in line with tier-1 commitments for this product class.
The use of triple-busbar (3BB) cells reduces the risk of microcracks and localized current losses compared to older dual-busbar designs, improving mechanical durability.
Tempered glass, a reinforced aluminum frame, and EVA/backsheet lamination confirmed in Kyocera's official datasheet provide resistance to high snow and wind loads, relevant for the Polish climate.
Kyocera has operated since 1959 and is one of the longest-standing silicon technology manufacturers, reflecting mature quality processes in PV cell production.
Module efficiency of 16.7% is notably lower than the comparable Loom Solar SHARK (20.65%) at the same 275 Wp power rating, meaning a larger required mounting area per kWp.
Kyocera exited North American panel sales in 2016 and closed its Tianjin (China) factory in 2022, concentrating production mainly on the Japanese and Asia-Pacific markets - this may limit warranty service and parts availability in Europe over a 25-year warranty term.
The 10-year product/materials warranty is shorter than some tier-1 competitors offering 12-15 years against manufacturing defects, despite an identical 25-year power output warranty.
- Efficiency of 16.7% is 5.1pp below the database median (21.8%)
- At 167.1 W/m², this panel generates 51.0 W/m² less per unit area than database median (218.1 W/m²)
- 19.0 kg weight - 7.5 kg lighter than database median (26.5 kg), reducing installation effort
- Ranked #13522 out of 14005 panels for efficiency in the database
