Average Solar Production In New York USA

Introduction – Data Source and Assumptions

Data is from the NREL.gov app for average solar radiation energy per day in New York City, New York. We used this reference point to compute the solar radiation energy production per day (in kWh/m²), which changes throughout the year according to the month. Each month is different due to the changing relative trajectory of the sun.

To get the monthly production, we simply multiplied by the number of days for each month. Finally to get the annual production, we added up all of the monthly values.

The average solar panel surface area is estimated to be 1.5 square meters. The efficiency of converting solar radiation into energy is estimated to be 15%.

Average Electricity Usage in New York and How Many Solar Panels You Need

The average monthly electricity usage in New York is 20 kWh per day, 600 kWh per month or 7200 kWh per year. Based on the data below, you would need 14-32 panels depending on the time of year to cover your electricity costs exactly. The variable factors are that electricity usage varies depending on how hot are summers and how cold are winters, and whether you use electricity based cooling and heating. Check with your solar system installer for exact numbers.
