In sunny states like California, Arizona, and Florida which get around 5.25 peak sun hours per day (or more), the average 400W solar panel can produce more than 61 kWh or more of electricity per month.

To help you determine the right solar system size for your home, use our Solar kW Calculator. This tool estimates the system size based on your monthly electricity bill, cost per kWh, and
knowing how many peak sun hours on average your location receives is useful because it lets you easily estimate how many solar panels or installed capacity needed to fulfill
To illustrate how many kWh different solar panel sizes produce per day, we have calculated the kWh output for locations that get 4, 5, or 6 peak sun hours. Here are all the results, gathered in
In sunny states like California, Arizona, and Florida which get around 5.25 peak sun hours per day (or more), the average 400W solar panel can produce more than 61 kWh or more of electricity per month.
Below is a month-by-month comparison of how average Florida solar radiation levels compare to average levels in an area with historcially high levels (NV) and one with historically low levels
According to the U.S. Energy Information Administration (EIA), the average Florida household uses about 1,110 kilowatt-hours (kWh) per month—which equals roughly 37
Data is from the NREL.gov app for average solar radiation energy per day in Jacksonville, Florida. We used this reference point to compute the solar radiation energy production per day (in
In sunny states like California, Arizona, and Florida which get around 5.25 peak sun hours per day (or more), the average 400W solar panel can produce more than 61 kWh or
Now we can multiply 1.75 kWh by 30 days to find that the average solar panel can produce 52.5 kWh of electricity per month. In sunny states like California, Arizona, and Florida which get around 5.25 peak sun hours per day (or more), the average 400W solar panel can produce more than 61 kWh or more of electricity per month.
A 300-watt solar panel will produce anywhere from 0.90 to 1.35 kWh per day (at 4-6 peak sun hours locations). A 400-watt solar panel will produce anywhere from 1.20 to 1.80 kWh per day (at 4-6 peak sun hours locations). The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations).
A 400W solar panel receiving 4.5 peak sun hours per day can produce 1.75 kWh of AC electricity per day, as we found in the example above. Now we can multiply 1.75 kWh by 30 days to find that the average solar panel can produce 52.5 kWh of electricity per month.
first you need to know the number of peak sunlight hours at your location. Let's assume you live in Austin, Texas, US. In Austin you can expect to receive about 4.9 peak sun hours per day on average. Once you calculate the system size, you can determine the number of solar panels or installed capacity needed to meet the energy requirements.
The calculator will do the calculation for you; just slide the 1st wattage slider to ‘100’ and the 2nd sun irradiance slider to ‘5.79’, and you get the result: A 100-watt solar panel installed in a sunny location (5.79 peak sun hours per day) will produce 0.43 kWh per day.
Two variables dictate how much energy your solar panels produce: 1. Solar Panel Wattage: Higher-wattage panels generate more kWh. Common sizes include 100W (small setups), 300-400W (residential), and 500W+ (commercial systems). Example: A 500W panel produces 50% more energy than a 250W panel under the same conditions. 2.
