Degradation rate is the annual percentage decline in a solar panel's power output over its lifetime. All solar panels lose performance over time due to physical and chemical changes in the cells and encapsulant.
This effect, known as the "Christmas light effect," occurs because the shaded cell reduces the current flowing through the panel, limiting the overall energy production.
Solar technology is evolving quickly. Our 2025 guide explains the latest advances like TOPCon, HJT, and back contact panels. Learn how each performs in efficiency, durability, and real-world applications.
A 305 watt solar panel is a photovoltaic module capable of producing 305 watts of power under Standard Test Conditions (STC). These panels typically feature 60-cell monocrystalline or polycrystalline configurations and measure approximately 65″ x 39″ in size.
Modern panels reach 18-23% efficiency. That means they convert about one-fifth of sunlight into usable power. But efficiency is only part of the story. Real-world performance changes with temperature, shading, tilt angle, and even the quality of the inverter or battery.
