Thanks to the **bifacial technology**, the panels generate energy from both sides - both from the front and from the back of the glass surface, which, under optimal conditions, results in significantly higher energy production compared to traditional modules in a glass-film laminate. The series stands out for its exceptional durability - the double layer of tempered glass effectively protects the cells from mechanical damage and harsh environmental conditions, ensuring long-term reliability of the installation. Another advantage is the prestigious **Cradle to Cradle Gold** certification, which confirms the manufacturer's environmental responsibility and the possibility of full recycling of components - an increasingly important aspect for investors concerned about the carbon footprint of their investment. The manufacturer stands out in the market with an exceptionally long **product warranty**, covering high efficiency for decades of operation - one of the best standards in the industry. The series is available in frameless, aluminum-framed, and full black versions, ideal for aesthetically demanding projects. SOLID Bifacial will be suitable for standard roof installations, BIPV systems, and agrophotovoltaics, where bifacial illumination of the cells is crucial for the profitability of the project. ## Notable figures - At 19.6% efficiency, this panel is 2.3pp below the \*\*database\*\* median of 21.8% - At 195.7 W/m², this panel generates 22.4 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.36%/°C temperature coefficient - 0.06pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - At 32.0 kg (5.5 kg above \*\*database\*\* median of 26.5 kg), requires checking roof load capacity - #12718 for efficiency, #13124 for temperature performance out of 14129 panels ## Questions ### How much more energy does the SoliTek SOLID Bifacial panel produce compared to conventional glass-foil modules? Under optimal conditions, the SOLID Bifacial series can generate up to 35% more energy than standard glass-foil modules. The rear glass pane captures diffuse and reflected light from the ground and redirects it to the solar cells, increasing annual yield. The bifacial gain is highest with bright surfaces beneath the array (snow, light gravel, concrete) and elevated or tilted mounting configurations, such as agrivoltaic systems. ### What warranty does SoliTek offer on the SOLID Bifacial series and what does it cover? SoliTek provides a 30-year product warranty and a 30-year power output warranty for the entire SOLID Bifacial series. After 30 years of operation, each panel is guaranteed to retain at least 90% of its rated output power. This is among the longest warranty standards available from a European manufacturer and is particularly relevant for commercial rooftop and ground-mounted systems with long investment payback periods. ### Are SoliTek SOLID Bifacial panels suitable for agrivoltaic installations? Yes, the SOLID Bifacial series is specifically well-suited for agrivoltaic applications. The glass-glass construction provides resistance to ammonia (present near livestock operations) and salt mist, while the frameless transparent variant allows diffuse light to pass through to crops below. Elevated mounting over fields means reflected light from soil and vegetation reaches the rear cell surface, maximizing bifacial energy yield throughout the day. ### What does the Cradle to Cradle Gold certification on SoliTek SOLID Bifacial panels mean and does it matter for buyers? The Cradle to Cradle Gold certification confirms that SoliTek meets strict environmental standards covering full recyclability of components, safe material composition, responsible water management, and fair labor practices. For investors reporting carbon footprint data or applying for ESG-linked financing, this certification is a meaningful differentiator, setting the SOLID Bifacial series apart from the majority of Asian-manufactured modules that carry no equivalent certification. ### Can SoliTek SOLID Bifacial modules withstand heavy hail and high winds? Yes. The dual 3.2 mm heat-strengthened glass panes make the SOLID Bifacial series among the thickest modules on the market. The panels are rated to Hail Class 5, meaning they withstand ice balls up to 50 mm in diameter. Wind resistance has been tested up to 320 km/h, making them suitable for demanding coastal and mountain locations where standard glass-foil modules would be at greater risk of damage. ### What variants of the SoliTek SOLID Bifacial panel are available, and which one works best for a rooftop installation? The SOLID Bifacial series is offered in three variants: frameless (lightweight, ideal for BIPV and clamp-based racking systems), aluminum-framed (up to 435 W, straightforward installation on standard rooftop mounting structures), and full black (black frame and black cells, designed for aesthetically demanding projects on dark roof tiles). For a typical pitched roof, the framed variant is the most practical choice since it is compatible with the vast majority of racking systems available on the market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SOLID_Bifacial_B60_370W_EN-framed_35x30mm_compressed-a2814b487462.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, 17 kg lighter, +3.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, 17 kg lighter, +3.6 pp | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -50 W, 16 kg lighter, +3.4 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -30 W, 16 kg lighter, +3.4 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -10 W, 16 kg lighter, +3.4 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +10 W, lighter, +3.4 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +30 W, lighter, +3.4 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +30 W, lighter, +3.4 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +10 W, lighter, +3.4 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Lighter, +3.0 pp, +10 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +140 W, cooler, +5.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +125 W, lighter, +5.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +135 W, cooler, +5.1 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +135 W, cooler, +5.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +120 W, lighter, +4.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +130 W, cooler, +4.9 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-bifacial-370 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
