Monocrystalline solar panels tend to be more efficient than polycrystalline solar panels, and both tend to perform better than thin-film solar panels. Polycrystalline solar panels are a popular option for homes but tend to have a lower efficiency rate than monocrystalline solar panels.
The latest version 65 of Solar cell efficiency tables, released in November 2024, is now available but requires a login or payment. Solar panel efficiency is measured under standard test conditions (STC) based on a cell temperature of 25 ° C, solar irradiance of 1000W/m2 and Air Mass of 1.5.
Monocrystalline solar panels: Monocrystalline solar panels are made from melted pure silicon formed into bars and cut into wafers. You can easily recognize them by their uniform dark color and rounded edges. They are more efficient and last longer than other types of panels.
We used six criteria, and we encourage you to use them when evaluating any solar panel brand. Here they are: The manufacturing quality of the company's factories, and the degree of integration across the solar value chain (ingots -> wafers -> cells -> panels) in their manufacturing process. Why? Less defects means less future warranty claims.
