300–449 W solar panels represent the small and medium-power category, which are ideal for solar systems for single-family homes, smaller buildings and outbuildings. These modules are typically manufactured using monocrystalline PERC technology, which ensures reliable operation and an efficiency of between 20–21%. Due to their compact size, the panels in this category can be easily installed on smaller roof surfaces, while providing stable performance even in poor light conditions.

Featuring quality modules from JA Solar, Trina Solar, Longi, Risen and Hyundai, these solar panels are built with a durable aluminum frame and tempered glass for long-term reliability. These solar panels are a good choice for those looking for an affordable yet efficient solution for smaller or expandable solar systems.
