Middle of its segment, heavy for its output
The MY Solar GOLD N-Type TopCon Bifacial series defines new efficiency standards thanks to the combination of N-type cells with an advanced bifacial structure. The use of TopCon technology allows for significantly higher solar energy conversion efficiency, which translates into real savings from the very first day of operation. The main advantage of this series is the minimization of light-induced degradation, which guarantees stable module power for decades. Thanks to bifacial energy generation, these panels perfectly utilize light reflected from the ground, making them an unrivaled choice for professional ground-mounted installations and flat roofs covered with a bright membrane. These modules solve the problem of efficiency drops at high temperatures, offering an excellent temperature coefficient. This is a solution dedicated to both photovoltaic farms and premium prosumers looking for maximum resistance to weather conditions and the lowest levelized cost of energy (LCOE). What sets them apart from the competition is the exceptional finishing aesthetics and high efficiency in low-light conditions, ensuring continuity of power production even on cloudy days. By choosing the GOLD series, you invest in the highest mechanical durability, which effectively protects the modules against micro-cracks and guarantees full energy security for years.
Ranking
Signals from the data
Utility-scale, commercial and hot-climate.
Weight-limited structures, roofs where every square metre has to count and tight roof space.
Bottom 2% of the TOPCon 700-750 W segment, against a median of 52.9. Ranked 9,361st in the whole database.
Bottom 7% of the TOPCon 700-750 W segment, against a median of 230.2. Ranked 3,989th in the whole database.
Bottom 11% of the TOPCon 700-750 W segment, against a median of 23.00%.
Efficiency up to 22.53% places the GOLD series among the top performers in the TOPCon segment - on par with Sunket's SKT680-700M12-132D5 (22.5%) and matching the reference Mysolar USA variant (22.53%) at the same 700 Wp maximum power.
The bifacial design captures light reflected off the ground, delivering a real energy yield boost in ground-mount installations and flat roofs with white membrane - at no extra module-level cost.
The manufacturer offers a 25-year product warranty and a 30-year linear power warranty, exceeding the standard 25-year power warranty common among many PERC and some TOPCon competitors.
N-type cells exhibit significantly lower light-induced degradation (LID) than older P-type PERC cells, resulting in more stable energy yield during the first years of operation.
Five power variants within a single series (680-700 Wp) make it easier to match module count to available roof space or inverter capacity without changing technology or mechanical specifications.
The manufacturer does not appear on the BNEF Tier 1 list (Q2 2026), which may limit access to bank financing for large-scale PV farm projects requiring modules from a bankable manufacturer list.
Peak efficiency of 22.53% is about 0.21 pp lower than the comparable Luxor Solar ECO LINE HJT Glass-Glass Bifacial series (22.74%), which can affect power density per roof area in large installations.
- Efficiency of 22.5% matches the TOPCon 700-750W median
- 225.3 W/m² power density is 4.9 W/m² below TOPCon 700-750W median (230.2 W/m²) - requires larger installation area
- Temperature coefficient of -0.30%/°C matches the TOPCon 700-750W median
- Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof
- Ranked #3982 out of 14005 panels for efficiency in the database
