Bonito Max from Navitas Solar is a series of 144-cell modules engineered for large-scale commercial installations and solar farms, where every percentage point of energy yield matters. At the core of the design is half-cut mono PERC technology with 10 busbars, which lets the panel operate like two independent circuits wired in parallel - this approach delivers increased shade tolerance, limiting power losses even when part of the module is partially shaded by leaves, bird droppings, or nearby structures. The cells are separated using a non-destructive laser cutting (NDLC) process, eliminating the microcracks typical of mechanical wafer cleaving and translating into greater long-term durability. The series spans a wide power range, making it easier to match the number of panels to a planned installation without mixing different models. Thanks to PID degradation resistance and a sturdy anodized aluminum frame, the modules hold up well under demanding operating conditions. For investors and installers, a key advantage is lower LCOE - a reduced cost of energy generation over the system's full lifecycle, driven by the combination of high efficiency, long lifespan, and minimized generation losses. It's a strong choice for those seeking a proven balance between cost and performance in utility-scale projects.

What owners get
Half-cut PERC 10BB with NDLC laser cutting

144 half-cut mono PERC cells with 10 busbars operate as two independent parallel circuits, improving shading tolerance. Non-destructive laser cutting (NDLC) eliminates microcracks typical of mechanical wafer breaking, translating into lower long-term degradation.

Efficiency on par with segment leaders

Peak efficiency of 21.67% matches the best comparable 144-cell PERC modules on the market - Exiom EX540-560M(B) (21.7%) and Fellow Energy FE72-18X (21.7%) - a gap of under 0.1 percentage point.

Wide power spread of 525-560 Wp

8 power variants in 5 W increments (525-560 Wp) allow precise matching of panel count to the target commercial or utility-scale installation capacity without mixing models, simplifying string design and logistics.

PID resistance and robust frame

PID (potential-induced degradation) resistance combined with an anodized aluminum frame ensures stable performance in demanding climates, relevant for large ground-mount and industrial installations.

Established manufacturer track record

Navitas Solar has operated since 2013, has roughly 3 GW p.a. of manufacturing capacity, and ranks among the top 10 Indian module manufacturers per JMK Research, reducing counterparty risk on long-term warranties.

Trade-offs
PERC technology, not TOPCon

The series relies on older mono PERC cells, while Navitas Solar itself already produces a TOPCon line with higher efficiency and lower LID degradation. Buyers seeking the latest N-type cell generation won't find it in the Bonito Max series.

No bifacial option

Unlike the comparable Premier Energies model (144 Half Cut PERC Bifacial Dual Glass, 560 Wp), Bonito Max is offered only as a monofacial module, ruling out additional rear-side energy gain in ground-mount installations or on high-albedo surfaces.

Common questions

6 answered
How many Bonito Max panels are needed for a 10 kWp installation?
With a unit power of 560 Wp, roughly 18 Bonito Max modules are needed to reach 10 kWp (18 x 560 Wp = 10,080 Wp). The exact count depends on inverter sizing and available roof or ground area, so it's best to confirm the design with an installer, especially for the large commercial installations this series targets.
How does Bonito Max's half-cut, 10-busbar technology differ from standard mono PERC panels?
In half-cut technology, cells are cut in half and wired as two independent circuits connected in parallel. This means partial shading, from leaves or a nearby structure, for example, only affects one half of the panel instead of the whole module. The additional 10 busbars improve current collection from each cell, boosting efficiency and reducing resistive losses compared to standard PERC panels.
What warranty does Navitas Solar offer on the Bonito Max series?
Navitas Solar provides a 10-year product warranty covering material and workmanship defects, plus a 25-year power output warranty guaranteeing sustained energy generation over the panel's lifetime. This is a standard protection level for commercial-grade panels, giving investors confidence in the long-term returns of their installation.
Is Bonito Max suited for large solar farms or also for residential installations?
The Bonito Max series was designed primarily for large commercial installations and solar farms, where maximizing energy yield across large surface areas is critical. Its high 560 Wp power rating, shading tolerance, and lower LCOE make it well suited for utility-scale projects, though it can also work in larger residential or business installations.
What does NDLC cell cutting mean in Bonito Max panels and why does it matter?
NDLC, or non-destructive laser cutting, splits cells into halves without mechanically breaking the silicon wafers. Unlike traditional mechanical cutting, the laser process avoids creating microcracks along cell edges, reducing the risk of hot spots and power degradation over time. This helps Bonito Max panels maintain higher durability and stable output throughout their service life.
Are Bonito Max panels resistant to PID degradation and harsh operating conditions?
Yes, Bonito Max modules carry certified resistance to PID, or potential-induced degradation, a power loss issue caused by voltage differences between cells and the frame or ground, common in large installations with long strings. The sturdy anodized aluminum frame also provides corrosion resistance and withstands wind and snow loads, making the panel suitable for harsher climates.
