The biggest difference compared to classic installations is **BIPV integration**, making it easier to maintain architectural coherence, especially with new construction and public buildings. In practice, the series addresses typical investor concerns: worries about appearance, risk of leakage, and cumbersome installation. Weather-resistant construction (including solutions against water, wind, and fire) and a ventilated design, which supports the roof's stable operation, have been implemented. Installation is facilitated by the **modular snap-lock structure**, speeding up roofing work and servicing. For investors focused on yield and longevity, it is important to note that the roof tiles utilize **high-efficiency cells** and are designed for low degradation. This solution is ideal for residential, multi-functional buildings, and roofs where appearance matters without compromising energy production. ## Notable figures - Efficiency of 13.5% is 2.5pp below the \*\*TOPCon 0-400W\*\* median (16.0%) - Power density of 134.7 W/m² is 25.1 W/m² below \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - needs more roof space - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 0-400W\*\* panels - Weight of 7.7 kg (15.8 kg below \*\*TOPCon 0-400W\*\* median of 23.5 kg) allows easier transport and roof mounting - In the top 100% for efficiency among all TOPCon panels ## Questions ### How do Trina Solar TEG Solar Tiles differ from regular panels installed on an existing roof? TEG Solar Tiles are a BIPV (Building Integrated Photovoltaics) solution - instead of being added on top of a finished roof, the tiles replace conventional roofing and serve as the waterproof roof layer itself. This keeps the building envelope visually clean and uniform, without visible mounting hardware, which matters especially for new construction and public buildings where architects prioritize a consistent facade. ### What warranty comes with Trina Solar TEG Solar Tiles solar roof tiles? The manufacturer provides a 10-year product warranty covering material and workmanship defects, plus a 25-year power output warranty. Trina Solar is a Tier 1 manufacturer with long-standing market presence, which supports warranty reliability - important given that this product simultaneously functions as the actual roof covering for decades. ### Are TEG Solar Tiles resistant to strong wind, rain, and fire? Yes, the construction is engineered for real roofing conditions, including wind resistance, watertightness against rainfall, and fire resistance classification. A ventilated substructure design also supports heat and moisture dissipation beneath the tiles, reducing the risks typically associated with fully roof-integrated PV systems. ### What is TOPCon cell technology used in TEG Solar Tiles, and is it worth it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology offering higher efficiency and lower degradation compared to older P-type PERC cells. In practice this means better energy yield over the system's lifetime and slower power decline year over year, which is meaningful given Trina Solar's 25-year power warranty on this series. ### Is installing TEG Solar Tiles more complicated than a standard PV panel installation? Installation is simplified by a modular snap-lock construction that connects individual tiles without complex per-unit wiring. This speeds up roofing crew work and simplifies servicing, since a single defective tile can be swapped out rather than an entire section of the array. However, it does require an installer familiar with BIPV systems rather than standard rail-mounted PV. ### What is the power output of a single TEG Solar Tile, and how many are needed for a typical house roof? A single tile in the TEG Solar Tiles series reaches up to 110 Wp maximum power. For a residential system around 5-6 kWp, roughly 45-55 tiles are typically needed, though the exact count depends on solar exposure, roof pitch, and the layout designed by a BIPV installer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/datasheet-teg-solar-tiles-e3b48c9e76cb.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | +40 W, +9.5 pp, +5 yr warranty | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | +20 W, +9.5 pp, +5 yr warranty | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | +30 W, +9.5 pp, +5 yr warranty | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | +20 W, lighter, +7.8 pp | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | +20 W, lighter, +7.8 pp | | [Renesola YH120W-18M](https://comparepv.com/panel/renesola-yh120w-18m) | 120 W | Hotter, +6.1 pp, +5 yr warranty | | [Easun Power YH100W-12M](https://comparepv.com/panel/easun-power-yh100w-12m) | 100 W | Hotter, lighter, +6.1 pp | | [Isola New Energy YH120W-18M](https://comparepv.com/panel/isola-new-energy-yh120w-18m) | 120 W | Hotter, +6.1 pp, +5 yr warranty | | [Isola New Energy YH100W-12M](https://comparepv.com/panel/isola-new-energy-yh100w-12m) | 100 W | Hotter, lighter, +6.1 pp | | [Centro Energy CE-100M36](https://comparepv.com/panel/centro-energy-ce-100m36) | 100 W | +20 W, hotter, +6.1 pp | | [Trina Solar TEB-NEGA2CD.48-85W (Clay)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-48-85w-clay) | 85 W | +0.8 pp | | [Trina Solar TEB-NEGA2CD.48-90W (Clay)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-48-90w-clay) | 90 W | +10 W, +1.7 pp | | [Trina Solar TEB-NEGA2CD.45-100W (Black)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-45-100w-black) | 100 W | +20 W, +3.3 pp | | [Trina Solar TEB-NEGA2CD.45-105W (Black)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-45-105w-black) | 105 W | +25 W, +4.2 pp | | [Trina Solar TEB-NEGA2CD.45-110W (Black)](https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-45-110w-black) | 110 W | +30 W, +5.0 pp | | [SunKean SKT110M10](https://comparepv.com/panel/sunkean-skt110m10) | 110 W | +30 W, hotter, +1.9 pp | --- Source: https://comparepv.com/panel/trinasolar-evergreen-shanghai-pv-tech-co-ltd-teb-nega2cd-48-80w-clay Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
