How to reduce solar risk from seasonal variability: Part II
How to reduce solar risk from seasonal variability: Part II

As we discussed in an article last month, it’s no secret that solar power generation can vary from season-to-season based on local weather conditions. So given this variability, how do PV system owners—whether residential, third-party, commercial or utility-scale...

Reducing PV project risk (and costs) with better PV modeling
Reducing PV project risk (and costs) with better PV modeling

Investment in PV presents unique risks, as the amount of energy a PV system produces is as variable as the weather. Unfortunately, quantifying PV risk can be just as daunting as predicting the weather. Today, researchers have access to more research methods and more...

See for yourself: 2012 was a good year for solar
See for yourself: 2012 was a good year for solar

Not only was 2012 a record-shattering year for PV system growth in the U.S., it was also a good year for solar power production. Compare our monthly average maps for 2011 and 2012 to see that many locations in the U.S. experienced significantly higher PV energy...

Tilt vs. flat-mount PV: does it really matter?
Tilt vs. flat-mount PV: does it really matter?

Have you ever wondered if PV system orientation really makes that much difference to the amount of power produced by a PV system? As the map below illustrates, the answer is typically yes, but to varying degrees. This ‘Energy Gains’ map depicts how tilting solar...
