SolarAnywhere® 2019 weather report: Midwest solar energy resource downturn continues for second year
In July 2019 we posted an article about unprecedented weather affecting the solar energy resource across much of the U.S. during 2018 and the first half of 2019. In that article, we anticipated a rebound during the second half of 2019. So now that 2019 is over, where...
A long history of data is key to solar project bankability
While the average power purchase agreement (PPA) price falls to keep solar competitive, the amount of global solar capacity developed in the past two-years has increased at a rate of roughly 30% year-over-year. This means that project developers are being forced to...
SolarAnywhere now-casts to support EDD-led U.S. DOE project to improve grid resiliency with interconnected DERs

At Clean Power Research, we think of ourselves as a modestly sized company doing big work. We are a passionate team of engineers, scientists and customer-obsessed service professionals focused on delivering world-class software solutions to utilities and the solar...
Could distributed solar + storage protect Californians from precautionary power outages?
Wildfires & California: A major concern California has experienced multiple devastating wildfires over the past two years. The Wine Country Fires that started on October 8, 2017, in Napa County killed 44 people and cost $15 billion. The Camp Fire, an even more...
Three keys to unlocking DER program management excellence
A question we often hear from utilities is: “What makes an effective distributed energy resource (DER) program management solution over the long-term?” The question is often rooted in concern for making the best choice between developing an in-house solution or...
PowerClerk Dashboards deliver key data visualization capabilities to energy program managers
Advancements in data visualization reporting tools are helping companies make sense of ever-increasing data volumes and complexity. The right tools help increase efficiency and make data visualization more approachable for all users. Improved application design has...
Demand for firm power driving innovation in solar forecasting
Since 2014, compelling economics have made renewable energy the preferred source of new power generation capacity in the United States. Energy cost parity with traditional sources has been well-established by the International Renewable Energy Agency (IRENA) and other...

When it comes to understanding solar resource risk, not all datasets are created equal
When it comes to ensuring that solar investments live up to power-production expectations, one important element is understanding the uncertainty of the solar resource. The lower the uncertainty of the background solar resource, the higher the likelihood a solar...
Intersolar North America 2014: The year of O&M and bankability
I often hear complaints that solar tradeshows aren’t offering much that is new and exciting—but I beg to differ. Every year I see trends emerging—trends that are often overlooked until months after the show. Intersolar North America was no exception. This year I was...
CSI RD&D project results: Forecasting behind-the-meter PV for the California ISO
In a recent NREL report, interviews of 13 operating entities in the Western Interconnection found that “Variable generation (VG) forecasting is widely considered to be a key means of integrating wind and solar power efficiently and reliably as these resources become...
Just how great was the solar resource in 2013 in California? Record setting!
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...
The solar value proposition part 2: Charting a new path using data and analytics
In Part 1 in our series on the solar value proposition, we looked at a new approach to valuing PV. With this new approach, there is a need to quantify deferred and avoided generation, as well as transmission and distribution capacity increases through peak-load...
Solar forecasts generated from satellite images help balance power grid
What do NASA and NOAA’s Geostationary Operational Environmental Satellites (GOES) have to do with balancing the power grid? Plenty, it turns out, for areas with a high penetration of solar energy production. Read about the link in NASA’s Energy Innovations blog...
Impact of the North American Monsoon on solar variability
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...
2014 solar trends episode 3: Solar Financing – A New Hope
Financing has been with solar since its earliest days. Before the lease and the power purchase agreement (PPA), residential solar customers would often purchase systems with cash. Cash payments are a form of financing, as the customer is choosing to purchase a solar...
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...

Solar Power International 2015: Solar in Disneyland
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...
Tapping the win-win-win of rate reform
Utilities nationwide are adding variety to residential electric rate plans and reconsidering how to value rooftop solar. Rate changes being considered include demand charges and net metering “2.0” policies that provide customers less than full retail credit. These...
Hot topics at Intersolar NA 2015: ITC, solar + storage and snow!
San Francisco once again played host to the Intersolar North America conference in July. For industry veterans, this year’s event was familiar: crowded registration lines, bumping into old friends and a busy exhibition floor. On the other hand, this year’s hot...
