Original answer

Short answer: Yes — high-efficiency, durable solar panels are widely available. If you want the best long-term performance, look for panels built on newer n-type cell technologies (HJT, TOPCon, and IBC) or high-quality monocrystalline PERC variants, robust materials (tempered glass, POE encapsulant), low degradation rates, and long warranties.

What “high efficiency” and “durability” mean

  • Efficiency: how much sunlight is converted to electricity. Commercial residential/commercial panels commonly range from ~18% to ~22% for standard mono‑crystalline PERC; higher‑end technologies (IBC, HJT, TOPCon, and certain bifacial/tandem designs) routinely reach mid‑20% and above in commercial products.
  • Durability: how well they resist weathering and keep producing power over decades. Durable panels have low annual degradation (often ≤0.5%/yr after the first year), robust materials, and long product & performance warranties (commonly 25 years performance).

Technologies to consider

  • Monocrystalline PERC: widespread, good efficiency/cost balance.
  • n-type TOPCon (Tunneling Oxide Passivated Contact): very good efficiency and lower light‑induced degradation; becoming a common high‑performance choice.
  • HJT (Heterojunction): high efficiency, excellent temperature performance and low degradation, usually premium priced.
  • IBC (Interdigitated Back Contact): very high efficiency, good aesthetics, often used in premium panels.
  • Tandem/perovskite-on-silicon (emerging/commercializing): promises higher efficiencies, but check for commercialization maturity and warranty.

Durability features to prioritize

  • Long performance warranty (25+ years with e.g., ≥80–90% rated output at warranty end).
  • Strong product warranty (10–25 years) and reputable manufacturer support.
  • Low degradation rates (look for specs like ≤0.5%/yr after first year).
  • Temperature coefficient: lower (more negative) values mean less loss at high temps (better is a less negative number, e.g., −0.25%/°C is better than −0.40%/°C).
  • Materials: tempered low-iron glass, corrosion-resistant frames, robust junction boxes and connectors. POE encapsulant often outperforms older EVA for long‑term resistance to browning and moisture.
  • Certifications: IEC 61215/61730, salt‑mist and ammonia resistance if you’re coastal or agricultural, and mechanical load ratings for snow/wind.

Other practical considerations

  • Installation quality and panel placement affect longevity and energy yield as much as panel choice. Proper mounting, good wiring, grounding, and avoiding hot‑spots matter.
  • Bifacial panels can increase yield in the right mounting environment but require appropriate racking and albedo conditions.
  • Watch for real-world degradation data and independent tests (PV‑lab, certification bodies) rather than just manufacturer claims.

Quick buying checklist

  • Technology: n‑type TOPCon, HJT, IBC for top efficiency/durability.
  • Efficiency: higher is better if you have limited roof area.
  • Warranties: ≥25‑year performance warranty and solid product warranty.
  • Degradation rate and temperature coefficient in datasheet.
  • Certifications for your environment (salt mist, PID resistance, UL/IEC).
  • Reputable installer/manufacturer and third‑party test results when possible.

If you want, tell me your location, roof size/tilt, and budget and I can recommend panel types or a short shortlist of specs to ask suppliers for.
