Originally published in the March/April issue of Solar Today. Within the solar industry, it’s common knowledge that the optimal orientation of solar photovoltaic (PV) panels in the Northern Hemisphere is typically south, to maximize electricity production over...
Solar resources naturally vary from year to year, and 2014 was no exception. While the 2014 average monthly solar resource map shows expected patterns, with the greatest energy output in the southwest, the real story is revealed by the PV power variance map. The PV...
While we all know that the energy production of solar PV systems can vary temporally on the short term (e.g., hourly and daily basis), monthly to annual variability can significantly affect the ongoing status of a developed PV solar asset. For developers and owners of...
2013 marked the driest year on record in most regions of California. While this weather pattern led to many brown lawns and thirsty reservoirs, clear skies allowed many locations to experience well above-average PV energy generation potential. To better understand...
Solar energy output is predominantly affected by seasonal solar variations and weather. The angle of the sun to the solar panel changes with the time of day and seasonal variations, changing the available solar resource in predictable ways. Weather also affects the...
