The MY Solar G&A N-Type TOPCon Bifacial series is an advanced solution for demanding investors who prioritize maximum efficiency and installation durability. The use of N-Type TOPCon cells ensures that these panels are characterized by near-zero light-induced degradation and outstanding efficiency even in low-light conditions. A key advantage is bifacial energy generation, which allows for a significant additional power yield from reflected light reaching the back of the module. This design effectively solves the problem of power loss over time, offering significantly slower material aging compared to traditional technologies. The series is ideal for professional ground-mounted installations and modern commercial roofs where maximizing return on investment is key. What sets them apart from the competition is primarily an exceptional temperature coefficient, which guarantees stable operation and lower energy losses during hot days. It is the choice for those seeking high-resistance technology against external factors, combining innovation with long-term reliability in Polish climatic conditions. By eliminating the LID phenomenon, these panels maintain the highest operating parameters through decades of use, making them a cost-efficiency leader in the premium segment.

What owners get
N-Type TOPCon cells, low degradation

N-Type TOPCon technology eliminates Light Induced Degradation (LID) typical of older PERC cells, resulting in a significantly slower power decline in the early years of operation and better performance under low-irradiance and diffuse-light conditions.

Bifacial dual-side generation

The bifacial design enables additional energy harvest from light reflected onto the rear side of the module, which is particularly beneficial in ground-mount installations on high-albedo surfaces (e.g., gravel, white roofing) and high-albedo commercial rooftops.

30-year linear power warranty

The 25-year product warranty combined with a 30-year linear power warranty is standard for top-tier N-Type modules and clearly exceeds older PERC terms (typically 25-year product / 25-year power warranty ending around 80.7%), translating into a longer period of predictable, guaranteed energy output.

Favorable temperature coefficient

TOPCon cells typically feature a lower power temperature coefficient (around -0.29%/°C versus roughly -0.35%/°C for PERC), reducing efficiency losses on hot days and supporting stable performance during Polish summer conditions.

Trade-offs
Efficiency below peer group average

The series' maximum efficiency is 22.95%, while comparable modules with the same maximum power of 620 Wp (HT-SAAE HT66-18X(ND)-F, Weran Solar LR7-72HTH, Astronergy ASTRO N7) reach 23%. The gap is modest but implies a slightly larger module area is needed to match equivalent output.

Not on the BNEF Tier 1 bankable list

MY Solar is not listed as a BNEF Tier 1 manufacturer, unlike many competing brands in this segment. This can complicate bank financing for large-scale projects and may affect insurance terms and resale valuation on the secondary market.

About the G&A N-Type TOPCon Bifacial series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the MY Solar G&A N-Type TOPCon Bifacial series carry and what does it cover?
The MY Solar G&A N-Type TOPCon Bifacial series comes with a 25-year product warranty covering defects in materials and workmanship, plus a 30-year linear power output warranty - one of the longest in the premium segment. The extended power guarantee is made possible by N-Type TOPCon cell technology, which degrades at only 0.4-0.5% per year, significantly slower than conventional PERC modules.
How does bifacial energy generation work in the MY Solar G&A series and how much extra output can I expect?
MY Solar G&A bifacial modules harvest reflected (albedo) light through their active rear surface in addition to the front side. In ground-mounted systems with light-colored gravel or soil, the rear side can contribute 10-25% additional yield on top of the 620 Wp nameplate rating. The rear-side bifacial factor reaches approximately 80-85% of front-side efficiency, making these modules especially cost-effective in open ground installations where reflected irradiance is available.
Do MY Solar G&A TOPCon panels suffer greater power loss on hot days compared to standard modules?
On the contrary - the G&A N-Type TOPCon series has a superior temperature coefficient of approximately -0.30%/°C, compared to around -0.40%/°C for PERC technology. At a typical summer module temperature of 65°C, TOPCon panels lose roughly 7.5% less power than an equivalent PERC module, resulting in measurably higher energy yield during peak summer hours.
Are the MY Solar G&A panels susceptible to LID (Light-Induced Degradation)?
No. The N-Type TOPCon cell architecture used in the G&A series is inherently immune to both LID and LeTID. In P-type PERC cells, these effects cause an initial 1-3% power drop within the first weeks of operation. N-type silicon does not contain the boron base responsible for light-activated defects, so the MY Solar G&A module delivers its full rated output from day one of operation.
Are the MY Solar G&A 620 Wp modules suitable for ground-mounted utility-scale PV installations?
Yes, the G&A N-Type TOPCon Bifacial series is designed with ground-mounted systems in mind. At 620 Wp, the module reduces the number of panels and overall BoS costs per megawatt. The bifacial design maximizes albedo gain at ground level, and the 30-year power warranty supports long-term LCOE calculations essential for utility-scale project financing.
How does the MY Solar G&A N-Type TOPCon series compare to older P-Type PERC panels from the same manufacturer?
The main advantages of the G&A series over P-Type PERC are: no LID effect, a better temperature coefficient (-0.30%/°C vs. ~-0.40%/°C), module efficiency exceeding 22%, and bifacial energy harvest that standard PERC panels typically lack. The power warranty is also extended to 30 years versus the typical 25 years for legacy PERC series, resulting in a substantially better LCOE over the system's lifetime.
