Not Enough Sun? Think Again!

Monday, April 2, 2012

One concern we hear often from those considering solar is whether there is enough solar in their area to make the investment worthwhile. The short answer: absolutely!

For the long answer, let’s take a look at this map, put out by the National Renewable Energy Laboratory1–click to zoom in.

NREL Solar Map

Taking a closer look at this map, we get a clear story of just how perfect for solar the United States is:

  • With the exception of Alaska, the entirety of the continental United States and Hawaii fall within the 1400-2500 kWh/m2/year range.
  • Germany has the largest solar market in the world2, and the photovoltaic resource potential for the entire country are in the lowest ranges of the chart.

The takeaway here is that the United States is above-average territory for photovoltaics (PV), and we have only just begun to realize the true and total potential for solar energy here.

No matter where in the country you’re located, there is enough sun for solar to work. PV is a smart choice–one that will save you money and save the environment we depend on.

NREL maintains monthly solar maps on their website if you’d like to learn more. Contact us if you have any questions or are interested in going solar.
