When it comes to solar resources, 2014 was anything but average
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...
Solar forecasting goes “EPIC”
Itron and Clean Power Research are embarking on the next phase of research that will lead to high-fidelity distributed solar photovoltaic (PV) forecasts, and integration of those forecasts into net load forecasts for the California Independent System Operator (ISO)....
Understanding PV variability: Affects of the 2014 California monsoon
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...
Using ground plus satellite solar irradiance data to reduce risk, increase project profitability
If you stopped by the Clean Power Research booth (#118) at the most recent Solar Power International (SPI) Conference in Las Vegas, you would have noticed a tall metal frame supporting some measurement equipment. While this structure could have passed for a new-age...
Solar fleet modeling part 3: Balancing the variability of PV
