The modules utilize **N-type TOPCon bifacial solar cell technology**, ensuring high efficiency even with diffused light - which is crucial for crops grown directly under the panels. The series is primarily distinguished by its **IEC 62716-certified ammonia resistance**, making it an ideal choice for livestock farms, poultry farms, and facilities exposed to aggressive chemical environments. The double-pane tempered glass structure provides a fire rating of A, exceptional resistance to hail and heavy snow loads - a reliable protection in Poland's variable climate. The **special Solrif D frame, certified by Ernst Schweizer AG**, allows for direct integration of the modules as a full roof covering, eliminating the need for additional mounting systems. As the only photovoltaic modules in the world, they hold a Cradle to Cradle Gold certification - 98% are recyclable and contain recycled glass. Manufactured in the European Union using only renewable energy, with a 30-year product and performance warranty. ## Notable figures - At 14.9% efficiency, this panel is 1.1pp below the \*\*TOPCon 0-400W\*\* median of 16.0% - Power density of 143.2 W/m² is 16.6 W/m² below \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 0-400W\*\* panels - At 35.0 kg, this panel is 11.5 kg heavier than the \*\*TOPCon 0-400W\*\* median (23.5 kg) - more demanding for installation crews - Ranked #13833 out of 14005 panels for efficiency in the database ## Questions ### Are Solitek SOLRIF D Agro modules suitable for agrivoltaic installations above crops? Yes, the SOLRIF D Agro series was designed specifically for agrivoltaics. The bifacial cells and glass-glass construction allow diffuse light to pass through, enabling crop cultivation directly beneath the panels. This means the same agricultural land simultaneously serves for energy production and full-value farming — without significant yield losses. ### What does TOPCon bifacial technology offer in the SOLRIF D Agro panels and does it matter on overcast days? N-type TOPCon cells deliver higher efficiency than standard PERC and perform better under diffuse irradiance — critical during the overcast days typical of Central European climates. Bifacial design means the module captures energy from both the front side and light reflected from the ground or snow, increasing annual energy yield by several percentage points depending on surface albedo. ### What warranty comes with the Solitek SOLRIF D Agro panels and what does it cover? The SOLRIF D Agro series comes with a 30-year product warranty and a 30-year power output warranty from the manufacturer Solitek. The power warranty guarantees the module retains a defined percentage of its nominal 300 Wp output throughout that period. This is one of the longest warranties available on the market, matching the expected investment lifetime of a PV system. ### Why is the SOLRIF D Agro recommended for livestock farms and environments exposed to ammonia? The series holds certified ammonia corrosion resistance per IEC 62716 — a standard most conventional framed panels do not meet. Ammonia fumes from pig or poultry operations corrode aluminum frames and seals, shortening module lifespan significantly. The glass-glass construction without exposed metal components allows the SOLRIF D Agro to withstand aggressive chemical environments throughout the full 30-year service life. ### Can SOLRIF D Agro panels replace a roof covering and how does the mounting work? Yes, the Solrif D frame certified by Ernst Schweizer AG allows direct in-roof integration as a fully functional roof covering. This eliminates the need for separate racking systems, reducing total system cost. The glass-glass build with tempered TVG glass provides fire class A rating and exceptional resistance to hail and extreme snow loads. ### What does the Cradle to Cradle Gold certification mean for the SOLRIF D Agro panels and why does it matter? Cradle to Cradle Gold is the highest independent sustainability rating for an industrial product. SOLRIF D Agro modules are 98% recyclable and incorporate recycled glass. They are manufactured in the European Union using 100% renewable energy. These are the only PV modules in the world holding this certification at Gold level, making them the go-to choice for investors requiring a full environmental footprint assessment. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Solrif-D-Agro-B64-300W-EN-datasheet-3ad3a981466c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | 22 kg lighter, +8.5 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | 22 kg lighter, +8.5 pp, -5 yr warranty | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, 21 kg lighter, +8.4 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | 20 kg lighter, +8.3 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | 20 kg lighter, +8.3 pp, -5 yr warranty | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | -15 W, 24 kg lighter, +8.1 pp | | [Gamko New Energy GKA182M260W](https://comparepv.com/panel/gamko-new-energy-gka182m260w) | 260 W | -40 W, 24 kg lighter, +8.1 pp | | [Gamko New Energy GKA182M270W](https://comparepv.com/panel/gamko-new-energy-gka182m270w) | 270 W | -30 W, 24 kg lighter, +8.1 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | 19 kg lighter, +8.1 pp | | [Solitek SOLRIF D Terracota Bronze 370](https://comparepv.com/panel/ginlong-solis-solrif-d-terracota-bronze-370) | 370 W | +70 W, +3.5 pp | | [Solitek Solrif D Satin 445](https://comparepv.com/panel/ginlong-solis-solrif-d-satin-445) | 445 W | +145 W, +7.2 pp | | [Solitek SOLRIF D Black 455](https://comparepv.com/panel/ginlong-solis-solrif-d-black-455) | 455 W | +155 W, +7.7 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +210 W, lighter, +10.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +195 W, lighter, +9.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +205 W, lighter, +9.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +190 W, lighter, +9.6 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solrif-d-agro-300 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
