The Powitt Solar M10 MONO MODULE (N-type) 580W-600W Bifacial Dual Glass series is designed for high energy yields where every meter of installation counts. The use of N-type TOPCon cells minimizes typical power losses over time and improves performance in less ideal conditions - at higher temperatures and in weaker sunlight. A key advantage is the bifacial design, which allows for energy generation from both sides, utilizing reflections from the ground - a real benefit on light-colored, membrane roofs, and in ground-mounted systems with suitable soil.

Dual glass, meaning glass on both sides of the module, contributes to durability and safe operation by stabilizing the laminate and improving resistance to moisture and environmental factors. The M10 series is suitable for PV farms, large commercial roofs, and projects where lower BOS costs are a priority, thanks to powerful modules and simpler assembly logistics. This is the choice for investors who expect long-term, predictable yields, rather than just specifications from a datasheet.

What owners get
N-type TOPCon cells

N-type TOPCon technology reduces LID/LeTID degradation and maintains higher efficiency at elevated temperatures and lower irradiance compared to older PERC cells, translating into higher real-world annual yield than nameplate power alone would suggest.

Bifacial dual-glass construction

Glass on both sides of the module improves moisture resistance and laminate rigidity, while the module also captures additional energy from light reflected off the ground - a real benefit on light-colored membrane roofs and ground-mount installations with suitable albedo.

Up to 23.23% efficiency, top of segment

The 22.46-23.23% efficiency range matches the best comparable N-type series on the market (Tongwei TWMND 72HD at 23.2%, Lexron 144 Halfcut TOPCon at 23.23%) and clearly exceeds the Talesun BISTAR TP7F78M series (21.5%) at the same 600W max power.

High module power lowers BOS costs

Up to 600Wp per module reduces the number of panels, connectors, DC cabling, and mounting hardware needed per kWp, meaningfully cutting BOS costs and installation time in PV farms and large commercial rooftops.

30-year linear power warranty

The 30-year power warranty places the M10 series in the premium segment, on par with leading N-type competitor series, giving investors long-term yield predictability for project financing horizons.

Trade-offs
Not a BNEF Tier 1 manufacturer

Powitt Solar does not appear on the Bloomberg New Energy Finance Tier 1 manufacturer list (unlike, for example, Boviet Solar, confirmed Tier 1 in Q1 2026), which can limit project bankability and complicate bank financing for larger commercial installations and PV farms.

Limited market track record

The M10 N-type Bifacial Dual Glass series was introduced in 2023, so unlike established Tier 1 manufacturers, it lacks multi-year independent field data confirming actual power degradation under operating conditions.

Common questions

6 answered
What warranty does the Powitt Solar M10 MONO MODULE N-type 580W-600W series come with?
The M10 MONO MODULE series carries a 15-year product warranty covering manufacturing defects and a 30-year linear power output warranty. The manufacturer guarantees no more than 1% degradation in the first year and less than 0.4% per year thereafter, ensuring more than 87% of rated power is retained after three decades of operation.
What is N-type TOPCon technology and why choose it over standard PERC?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture with an added passivation layer that minimizes charge carrier recombination. Compared to P-type PERC, it delivers higher efficiency (up to approx. 23.2%), a lower temperature coefficient (approx. -0.30%/°C), zero LID and LeTID degradation, and slower long-term power loss over 30 years. The practical result is more kilowatt-hours produced from the same roof area.
How much extra energy can the bifacial Powitt Solar M10 generate compared to a monofacial module?
The bifacial design of the M10 series captures energy from both the front and rear of the module by utilizing albedo light reflected from the ground surface. On ground-mounted systems with light-colored gravel or on rooftops with white TPO/PVC membranes, the bifacial gain can range from a few percent up to 25-30%. In practice this translates into a lower LCOE without increasing the module count.
Are the M10 Dual Glass Powitt Solar modules suitable for large commercial rooftops and utility-scale PV farms?
Yes, the M10 580W-600W dual glass series is specifically designed for commercial rooftops and utility-scale PV farms. High unit power of up to 600 Wp reduces BoS costs — cabling, racking, and inverters — per megawatt of installed capacity. The glass-glass construction also improves resistance to moisture, ammonia, and UV exposure, which matters in more demanding environmental conditions.
How do Powitt Solar M10 600W panels perform in high summer temperatures?
The N-type TOPCon cells used in the M10 series have a power temperature coefficient of approximately -0.30%/°C, which outperforms typical PERC modules at -0.35%/°C. When a panel heats up to 60°C during a summer day, the power loss is noticeably lower. Over hot summer months this difference can translate into 2-4% more energy generated compared to older P-type technology.
Is Powitt Solar a Tier 1 manufacturer and how does that affect project financing?
Powitt Solar is not currently listed as a Tier 1 manufacturer on Bloomberg NEF rankings. For investors financing a project through a bank loan or leasing, this is worth verifying with the lender or insurer, as some financial institutions require modules exclusively from Tier 1 producers. For retail and smaller commercial projects this typically has less impact, and the underlying N-type TOPCon technology remains fully sound from a technical standpoint.
