A solar panel 400 W may produce around 400 watts of power under optimum conditions. However, the output may differ based on sunshine intensity, panel orientation, and weather conditions.

What is a 400-watt Solar Panel?

When characterising the size of a panel, you usually refer to its power output capability, measured in watts. Under ideal Standard Test Conditions, a solar panel 400 w may provide 400 watts of direct current (DC) electricity. 400-watt solar panels are typically 5.4 feet long and 3.25 wide, with 60 to 66 solar cells per square foot. Standard Test Conditions, or STC, are laboratory criteria against which solar panels are tested. In these perfect conditions, a solar panel 400 w will only output 400 watts of power.

How Much Power Does a Solar Panel 400 W Generate?

Power and energy are different, and understanding the distinction is critical. We stated that a solar panel 400 w will produce 400 watts of power under ideal conditions. The amount of energy produced determines how much power is generated during a given time. A solar panel 400 w on your roof will create between 1.2 and 1.5 kilowatt-hours (kWh) of electricity daily.

The amount of electricity a solar panel generates is determined by various factors, including environmental conditions and the amount of sunshine that your roof receives. The table below shows how much electricity a solar panel 400 watts will generate in various parts of the United States:

Region Solar Energy Produced Daily Solar Energy Produced Monthly
North East 1.1 kWh 34 kWh
Midwest 1.2 kWh 37 kWh
South East 1.3 kWh 40 kWh
South 1.4 kWh 43 kWh
West 1.3 kWh 40 kWh

What Does a Typical 400-watt Panel Cost?

A high-quality solar panel 400 w will cost $250 to $300 per panel. This pricing excludes any additional equipment required to use the panel or installation charges. It is improbable that you will only buy one solar panel. Installing a complete 7 kW solar system with a solar panel of 400 watts would cost $19,950 before incentives. When you include the federal solar tax credit, the price reduces to around $14,000. The cost varies depending on market conditions, your area, your solar panel brand, and the solar installer you choose.
