Which type of solar panel has the highest efficiency but also highest cost?
- Monocrystalline
- Polycrystalline
- Thin-film
- Amorphous
Answer: Monocrystalline
Monocrystalline panels use single-crystal silicon, offering 15-22% efficiency and longer lifespan but higher cost. Polycrystalline is cheaper with 13-16% efficiency. Thin-film is flexible and lightweight but less efficient (10-13%). Choice depends on space, budget, and application. Relevant for renewable energy questions.
