4 FAQs about Wattage of glass solar panels

What is solar wattage?

Wattage refers to the amount of electrical power a solar panel can produce under standard test conditions (STC), which simulate a bright sunny day with optimal solar irradiance (1,000 W/m²), a cell temperature of 25°C, and clean panels. In simpler terms, a panel's wattage rating tells you its maximum power output under ideal conditions.

How much wattage does a solar panel use?

However, wattage alone doesn't tell the full story—actual solar panel output depends on sun exposure, climate, and installation quality. Large rooftops and utility-scale projects use bigger, more powerful commercial solar panels ranging from 500 to 700 watts.

How many Watts Does a solar panel produce per square foot?

The average solar panel output per area is 17.25 watts per square foot. To find out how many watts your solar panel produces per square foot, divide the specified wattage by the square footage of the panel.

How much power do solar panels produce?

About 97% of solar panels quoted on the EnergySage Marketplace in 2025 are 400 to 460 watts—expect to see panel outputs in this range in your quotes. Your panels' actual output will depend on your roof's shading, orientation, and hours of sun exposure. The efficiency and size of your solar panels drive their power output.
