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. ## Notable figures - 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 ## Questions ### What warranty does MY Solar offer on the GOLD N-Type TOPCon Bifacial series? MY Solar provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty for the GOLD N-Type TOPCon Bifacial series. The 30-year power guarantee is among the longest available on the market, giving investors confidence in long-term energy yield projections. Keep purchase documents and the warranty card on file for any future claims. ### Are MY Solar GOLD TOPCon Bifacial panels suitable for ground-mount or flat-roof installations? Yes, the GOLD N-Type TOPCon Bifacial series is specifically optimized for ground-mount systems and flat roofs with light-colored membranes. The bifacial design captures energy on both the front and rear sides of the module, utilizing light reflected from the ground surface to boost annual energy yield by up to 10–15% compared to monofacial panels. The lighter the surface beneath the array (white TPO membrane, light gravel), the greater the rear-side gain. ### What is TOPCon technology and why does the GOLD series perform better in high temperatures? TOPCon (Tunnel Oxide Passivated Contact) uses an N-Type silicon cell with an ultra-thin tunnel oxide layer that reduces carrier recombination. This results in higher conversion efficiency and a better temperature coefficient than conventional PERC cells. MY Solar GOLD modules lose less power as cell temperature rises, delivering higher real-world energy yields during summer heat and a lower LCOE over the system's lifetime. ### What is the maximum wattage available in the MY Solar GOLD N-Type TOPCon Bifacial series? The top power rating in the MY Solar GOLD N-Type TOPCon Bifacial series is 700 Wp, measured under Standard Test Conditions (STC). This figure does not include additional energy harvested from the rear side of the bifacial module. In real ground-mount installations the effective power output can exceed the STC nameplate rating, making this series particularly attractive for utility-scale PV projects where every additional watt directly impacts ROI. ### Does the GOLD series perform well on overcast days and in low-light conditions? Yes, the N-Type TOPCon cells used in the MY Solar GOLD series deliver strong low-light performance. Compared to P-Type PERC technology, TOPCon cells generate proportionally more energy under diffuse and overcast irradiance conditions. This is especially relevant in Central and Northern European climates where a significant share of annual solar radiation arrives as indirect, scattered light during autumn and winter months. ### Is MY Solar a Tier 1 manufacturer, and is the GOLD series a good investment for residential prosumers? MY Solar is not currently listed as a Tier 1 manufacturer under Bloomberg NEF classification; however, the GOLD N-Type TOPCon Bifacial series delivers premium-class specifications: TOPCon cell technology, bifacial design, up to 700 Wp output, and a 30-year power warranty. For premium prosumers prioritizing high efficiency and low LCOE, it is a compelling option. We recommend verifying local warranty service availability with your installer before purchasing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/mysolar-gold-topcon-n132-framed-bifacial-module-680-700w-202-8ee898cab5c6.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -50 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | Cooler, lighter, +2.3 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | Cooler, lighter, +2.3 pp | | [MY Solar MS400N-HJTPB](https://comparepv.com/panel/my-solar-ms400n-hjtpb) | 400 W | -300 W, lighter, -9.7 pp | | [MY Solar MS405N-HJTPB](https://comparepv.com/panel/my-solar-ms405n-hjtpb) | 405 W | -295 W, lighter, -9.5 pp | | [MY Solar MS410N-HJTPB](https://comparepv.com/panel/my-solar-ms410n-hjtpb) | 410 W | -290 W, lighter, -9.3 pp | | [MY Solar MS415N-HJTPB](https://comparepv.com/panel/my-solar-ms415n-hjtpb) | 415 W | -285 W, lighter, -9.2 pp | | [MY Solar MS420N-HJTPB](https://comparepv.com/panel/my-solar-ms420n-hjtpb) | 420 W | -280 W, lighter, -9.0 pp | | [MY Solar MS680N-DHBG](https://comparepv.com/panel/my-solar-ms680n-dhbg) | 680 W | -20 W, -0.6 pp | | [MY Solar MS685N-DHBG](https://comparepv.com/panel/my-solar-ms685n-dhbg) | 685 W | -15 W, -0.5 pp | | [MY Solar MS690N-DHBG](https://comparepv.com/panel/my-solar-ms690n-dhbg) | 690 W | -10 W, -0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +105 W, cooler, +2.6 pp | --- Source: https://comparepv.com/panel/my-solar-ms700n-dhbg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
