Yes, you can mix solar panels with different wattages—but there's a catch. " Explore the electrical science behind mixing panels, learn which connection methods work best, and discover the technologies that can help your mixed-panel system perform at near-perfect efficiency. This is because the voltage gets added up, while the current stays the same. When your panels have the same voltage but different current, you need to. . Does anyone know if you can use a string of panels of say 48 volts and another string of 24 volts into a combiner box then into a charge controller? Or do they all have to be the same voltage. While it is technically possible, it is not generally advised due to reduced efficiency and power output.
