Two of the most popular types of solar panels, monocrystalline and polycrystalline, are categorised as Tier Just one. Monocrystalline (mono) panels supply greater performance scores and greater ability output, but they’re much more high-priced. Polycrystalline (poly) panels are more reasonably priced but give lessen effectiveness and output. Due to the fact mono panels are bigger-high-quality, they have a reduced degradation amount.
