Solar resource variability is an unavoidable natural characteristic that impacts solar power forecasting. However, its impact on forecast uncertainty can be reduced by providing information on predictive uncertainty, along with deterministic forecast values. Having...
If you own an iPhone, you’ve seen the familiar message “iOS 9.3.3 is available for your iPhone and is ready to install.” If you’re like me, you hit “Remind me later” a few dozen times before you actually install the update. Call me paranoid, but I always have to take...
In our last blog, we talked about the performance of SolarAnywhere® v4 PV fleet forecasts, and discussed how accuracy was a function of the PV fleet’s geographic footprint. For instance, SolarAnywhere hour-ahead forecasts in the Western U.S. were shown to have a...
PV fleet forecasts Solar forecasts are traditionally concerned with predicting the output of solar PV systems at particular locations. Consequently, much of what is known about solar forecast accuracy is centered on point validations. Fleet forecasts consider the...
The capacity of behind-the-meter PV systems is growing steadily. Figure 1 illustrates that there is over 5 GW of PV in California alone. The number is continuing to increase. The result is that behind-the-meter PV fleet forecasts are becoming increasingly important...
Bankable solar irradiance data is crucial to minimizing cost of capital for solar projects. Check out this infographic to find out what you need to know when selecting resource data. Want to see the infographic in full size? Download it now: Download...
Utilities and grid operators need to procure and provide generation sources for anticipated load demands. As both grid connected and behind-the-meter photovoltaic (PV) systems continue to grow in number, total system load, including the load being served by solar, is...
In recent years, Clean Power Research created a solar forecast method to accurately predict power production of “invisible,” behind-the-meter PV systems—typically those found on homes and commercial buildings. In our approach, forecasts are generated by simulating the...
Disneyland provided the backdrop for the Solar Power International (SPI) conference in Anaheim this year. As the biggest solar-focused conference in the U.S., exhibiting at SPI provides a great opportunity to find out firsthand what is on the mind of the industry—that...
