FAQs 6

What is the wattage rating of a solar panel?

The Wattage rating of a solar panel is the most fundamental rating, representing the maximum power output of the solar panel under ideal conditions. You’ll often see it referred to as “Rated Power”, “Maximum Power”, or “Pmax”, and it’s measured in watts or kilowatts peak (kWp).

What is a power rating for solar panels & inverters?

The power rating for solar panels and inverters provides valuable data for various applications throughout the PV system lifecycle. Solar installers use rated power to calculate the number of panels and the proper inverter size needed to meet a project's energy requirements.

What is the efficiency rating of a solar panel?

Most solar panels have an efficiency rating between 17%-23%. A solar panel with a 21% efficiency rating means it converts 21% of the sun’s energy striking it into electricity. Do not confuse the efficiency rating with the rated output. A 23% efficiency rating does not mean the panel will only produce 23% of its rated output in watts.

What does a solar panel power rating mean?

While power ratings are designed to indicate the power potential of a solar panel, efficiency ratings are another important indicator of the panel’s overall quality. Efficiency ratings continue to improve, but currently, they tend to range between 15% and 20%.

What is rated power?

Rated power definition: also known as the power rating, indicates how much power an appliance (like a solar panel) can generate under ideal test conditions. This specification details the maximum power output the manufacturer designed the solar panel to deliver.

Are solar panels rated in watts more powerful?

As you would expect, the higher the solar panel is rated in watts, the more powerful it is. These higher efficiency solar panels can produce more DC electricity in the same amount of space as similarly sized solar panel with a lower power rating.
