Flexibility meets reliability: PVWatts and NSRDB now available through Clean Power Research API services
In keeping with our mission of powering intelligent energy decisions, Clean Power Research is introducing a 10 km Typical Meteorological Year (TMY) dataset for use in Clean Power Research API services. Programmatic access to this high-resolution dataset and the...
Power from solar: how much can you expect?
Determining whether solar is right for you depends in large part on the amount of solar resource available where you live. Each month, we generate the PV Power Map using SolarAnywhere® irradiance data. These maps provide more than just an indication of the solar...
Case study: Forecasting production of 170,000+ distributed PV systems
Falling photovoltaic (PV) system prices along with financing and installation innovations are driving continued rooftop solar growth—expected to be 30% in 2013 as reported by GTM Research. These customer-sited power generation resources are increasingly impacting...
How much is your land worth? Using solar irradiance data to quantify energy potential
Greentech Media’s recent article “How to Make Money from Land as a Solar Developer,” highlighted critical steps in the development of large solar projects that can make or break profitability. These include sizing the plant, applying for interconnection and a power...
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...
What solar leasing companies need to know to protect their investment—and their bottom line
A critical aspect of the financial health of solar leasing companies or other ‘third-party owners’ (TPOs) is the performance of their ‘fleet’ of installed PV. When a PV system is not operating at peak performance, it's not producing as much power as expected, which...
How to account for seasonal variability in solar power production
Intuitively, we know that solar power generation is dependent on seasonal weather conditions. The January and February PV Power Maps, published in the May/June 2013 issue of Solar Today, illustrate that this year was no exception, with month-to-month variability...
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
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...
