Solar technology is evolving quickly. Our 2025 guide explains the latest advances like TOPCon, HJT, and back contact panels. Discover the six main types of solar panel, including thin-film, perovskite, and the best type for your home: monocrystalline. What kind of home do you live in? When you're considering whether to get solar panels, it's a good idea to look into all the different types, to ensure you choose the best. Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%. Each kind of solar panel has different characteristics, thus making certain panels more suitable for different types of solar installations. When acquiring new solar panels, customers consider aspects like power output, efficiency, aesthetics, and even solar cell technology like Interdigitated Back Contact (IBC) or Passivated Emitter and Rear Contact (PERC), but few pay attention to the inner layers of the cell that constitutes an. Solar technology is evolving quickly. Learn how each performs in efficiency, durability, and real-world applications. Still, every home is different, and most will benefit.
