JA Solar 405W Mono PERC Half-Cell MBB All Black MC4 Solar Panel
Thinking of installing solar panels for your home, farm, or garden office? Look no further. These solar panels are reliable, efficient, and cost-effective, offering an attractive payback period. Well-designed in a durable black frame, these panels are suitable for domestic, farm, garden office, and similar rooftop installations.
The JA Solar 405W Mono PERC Half-Cell MBB Black Frame MC4 (JAM54S-31-405-MR-AB) is a 405W monocrystalline PV module with 108 Half-Cell technology. JA Solar offers a high-efficiency module with PERC cells, which, thanks to its half-cell configuration, provides high power output, better temperature coefficient, lower efficiency loss against shading, and higher resistance to mechanical loads. JA solar panels come with a 12-year product warranty and a 25-year linear output warranty.
Ideal for off-grid photovoltaic solar energy installations, these panels stand out for their incredible quality/price ratio and their great power in a small size.
Features:
- SUPER HIGH EFFICIENCY PERC MODULE: Assembled with 11 BB PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on energy generation, lower risk of hot spots, as well as enhanced tolerance to mechanical loading.
- DURABLE, DUST & WATER RESISTANT: JA solar's monocrystalline modules offer an excellent response even in extreme temperature conditions or low solar radiation, such as on cloudy days, at dawn, or dusk. The advanced, textured glass surface of the photovoltaic cells offers unsurpassed resistance to high levels of sea salt, ammonia, dust, or sand.
- MORE RELIABLE: Built-in half cut cell technology. Lower internal current, lower hot spot temperature. Cell crack risk limited to a smaller area of the cell. Innovative symmetrical module design means better shading tolerance. Heavy snow load up to 5400Pa and increased wind load up to 2400Pa.
- SUPERIOR WARRANTY: 12-year product warranty and 25-year extra linear power output warranty.
Must be installed by a licensed technician or electrician.

Frequently Asked Questions
HOW GOOD IS THE JA SOLAR PANEL?
The JA Solar panels are reasonably priced, comparable to Trina Solar, LONGi Solar, and Canadian Solar. With an average efficiency of 20%-21%, JA panels are among the most efficient in this price range. Additionally, these panels are highly durable and offer excellent shading tolerance.
WHO MANUFACTURES JA SOLAR PANELS?
JA Solar Holdings, a solar development company founded in the Yangpu district, Shanghai, manufactures JA Solar panels. They design, develop, manufacture, and sell solar cell and solar module products, operating from the People's Republic of China. Established in 2005, JA Solar has a global presence, with products sold in 135 countries and regions. Recognized for continuous technological innovation, a sound financial condition, and a well-established global sales and customer service network, JA Solar is acknowledged as a leading global manufacturer of high-performance PV products.
WHAT IS THE PRODUCTION CAPACITY OF JA SOLAR MODULES?
By the end of 2022, JA reported module orders totalling 25.47 GW, primarily comprising the 182mm size. In January and February 2023, they had already shipped 6.7 GW. The module production capacity until the end of 2022 was close to 50 GW, with wafer and cell capacity roughly 80% of the module capacity.
WHAT CLASSIFICATION DOES JA SOLAR HOLD?
JA Solar modules are classified as Class A according to the IEC 61730-2 standard. For roof installations, it is recommended to mount modules over a fire-resistant covering suitable for the application, ensuring adequate ventilation between the modules' backsheet and the mounting surface.
IS JA SOLAR CONSIDERED TIER 1?
Yes, JA Solar is considered a Tier 1 solar panel manufacturer, alongside examples such as Jinko Solar, LONGi, Trina Solar, and Canadian Solar.
WHAT DEFINES TIER 1 SOLAR PANELS?
Tier 1 solar panels are manufactured using the highest quality silicon, leading to more effective performance. Additionally, Tier 1 manufacturers employ advanced robotic methods to regulate the production process, reducing or eliminating human mistakes.
HOW LONG DO TIER 1 SOLAR PANELS LAST?
Tier 1 solar panels typically come with a 25-year industry-standard warranty. In reality, these panels often last longer, with the warranty guaranteeing efficiency above 80% after 25 years.
WHAT ARE JA SOLAR MBB PANELS?
MBB stands for Multi Busbar, indicating that a solar cell is equipped with 12 or 16 busbars instead of 4, 5, or 6. This configuration results in modules providing a higher power output and increased reliability, with approximately a 2%-2.5% power increase (in percentage range due to differences in cell efficiency and types).
WHAT IS AN MBB HALF-CELL MODULE?
Assembled with multi-busbar PERC cells, the half-cell configuration of the modules offers advantages such as higher power output, better temperature-dependent performance, reduced shading effect on energy generation, lower risk of hot spots, as well as enhanced tolerance for mechanical loading.
WHAT IS THE EFFICIENCY OF JA SOLAR PANELS?
The efficiency of JA Solar panels usually ranges between 20% and 21%, which is above average on the market. JA Solar engineers incorporate popular modern solar technologies, including half-cut cell construction, PERC cell technology, and busbars.
ARE HALF-CELL SOLAR PANELS BETTER?
Yes, since half-cell modules produce more power and are more efficient and reliable than their full-cell counterparts, their use can lead to time and money savings for the installer. By delivering more power per square meter, fewer panels are required to generate the same power.
