Middle of its segment, modest efficiency
MSolar MS series MONO 350-370W 9BB panels are a modern solution based on 9-busbar technology, which significantly shortens the electron flow path, reducing resistive losses and minimizing the risk of micro-cracks. The use of monocrystalline cells in this series guarantees higher efficiency even in less favorable lighting conditions, which directly translates into stable energy yields throughout the year. What sets this line apart from the competition is its high resistance to mechanical loads, making the modules perform excellently in extreme weather conditions such as strong winds or heavy snow accumulation. This series was designed for users seeking maximum efficiency from limited roof space, making it an ideal choice for owners of single-family homes and small commercial facilities. Thanks to precise quality control and an optimized temperature coefficient, these panels maintain excellent operating parameters even on hot days. By choosing MSolar MS, investors gain the assurance of long-term reliability and an aesthetic installation appearance that blends perfectly with modern architecture. It is a wise choice for those who value proven technology and solid workmanship without unnecessary compromises.
Ranking
Signals from the data
Tight roof space, roofs where every square metre has to count and weight-limited structures.
Bottom 14% of the 250-450 W band, against a median of 20.74%.
Bottom 15% of the 250-450 W band, against a median of 207.4.
Bottom 17% of the 250-450 W band, against a median of 54.4.
Nine busbars shorten the current collection path, reducing resistive losses and lowering the risk of cell microcracks, which supports more stable module performance over time.
The top efficiency figure (19.8%) is competitive within the mono segment and close to the Solitek SOLID Bifacial result (19.57%), delivering solid energy yield on limited roof area.
The module design offers enhanced resistance to wind and snow loads, making the series a suitable choice for sites exposed to harsh weather conditions.
Power up to 370W in a standard module footprint makes the series attractive for single-family homes and small commercial buildings with limited mounting area.
The panels maintain more stable performance at high temperatures, limiting energy output drops during hot summer days compared to modules with weaker temperature coefficients.
The manufacturer does not appear on the BloombergNEF Tier-1 list, which can complicate bank financing for the project and reduce investment attractiveness compared to bankable brands such as Solarwatt or Solitek.
The series' lower efficiency bound (18.75%) is clearly below comparable products at the same peak power - Selfa SV120M.3.2 (20.3%) and Solarwatt vision GM 3.0 (19.9%) - meaning the 350W variants yield less energy per unit of roof area.
Unlike the comparable Solitek SOLID Bifacial model at the same peak power (370W), the MSolar MS series is offered only as a monofacial module, excluding the extra albedo-driven energy gain available on light-colored roofs or ground-mount installations.
- At 18.8% efficiency, this panel is 3.1pp below the database median of 21.8%
- 189.2 W/m² power density is 28.9 W/m² below database median (218.1 W/m²) - requires larger installation area
- Temperature coefficient of -0.36%/°C is 0.06pp worse than database median (-0.30%/°C) - higher losses in summer heat
- Weight of 22.0 kg (4.5 kg below database median of 26.5 kg) allows easier transport and roof mounting
- Ranked #13047 out of 14005 panels for efficiency in the database
