More Information on New Jersey Green Energy

New Jersey ranks pretty low in average peak sun hours compared to other states in the US, but they don’t call it the garden state for nothing, there is plenty of sun to make solar power a legitimate option for electricity production in your home or business.

The local governments understand the power of the great sun in this Atlantic coast state, offering future mandates that require the energy output of the state to be at higher levels in the near future. New Jersey, even with their lower ranked average peak sun hours, ranks very high in solar output and capacity, treading the path to becoming a global leader on solar power and other renewable energy options like wind turbines.

The summer offers higher average peak sun hours per day as New Jersey is located in the Northern Hemisphere, but the winter can still offer output with growing technology and appropriately placed and run systems.

Using averages from a fixed solar panel, there are 4.21 hours of peak sun light across the state of New Jersey. This number would vary if you were using a 1-Axis or 2-Axis tilt panel.

Taking the average daily sun light hours works well for looking at long term calculations in your area. On a daily basis this number will fluctuate due to several outside variables. For example, on a cloudy day in the winter this number would be low, but on a sunny day in the summer this number could be much higher. Looking at an average will help you calculate and plan for the output and best hours of solar insolation you can expect from your solar panels in New Jersey throughout the year.
