Demystifying battery storage for residential energy customers: an overview (Part 1)
Grid-connected battery storage is an exciting, new and rather mysterious technology. The press is particularly interested in the solar + storage technology bundle. Headlines declare how inexpensive it is to bundle PV with batteries. Some articles even suggest that an...
Change is a constant: why agile software development fits today’s utility
As a developer of software for utility companies, we're frequently asked for information about integrating PowerClerk®, WattPlan® and SolarAnywhere® into utility processes. Often these requests include long lists of questions about product features and pricing, as...
A better way for utilities to forecast DER adoption
Since the Great Recession, utility planners have consistently over forecasted peak and total load. Econometric models used in the past are failing: energy efficiency continues to decouple load growth from Gross Domestic Product and customer energy habits are changing....
New SolarAnywhere PXX Data Streamline Probability of Exceedance Energy Calculations
Until now, SolarAnywhere® has offered two types of data: time-series and typical year (TGY). Today we’ve added a third option, probability of exceedance, or PXX for short. The “XX” refers to the probability that the level of irradiance will be exceeded in a given...
Solar+ home proven: a milestone reached
This article is a follow-on to Clean Power Research’s 11-part series on Solar+ homes series. Solar+ homes describes how homeowners can combine simple energy efficiency measures, solar PV, electric vehicles (EVs) and appliance electrification to create households that...
Accurate DER data is key for utility planning: PowerClerk makes it possible
A key to managing utility distributed energy resource (DER) programs is capturing the right information—not only to complete interconnection requests, but also to support a host of emerging utility planning and business intelligence needs. As discussed in a previous...
Higher-resolution data and broader geographic access with new SolarAnywhere Data license options
Thanks to our subscribers, partners and hard-working development team, SolarAnywhere® has become the most trusted and vetted solar resource dataset available. In 2017 alone, the SolarAnywhere team: Topped an EPRI study for forecasting Spotted a calibration issue at...
Defining DERs: Does it matter that we all seem to have slightly different definitions?
Over the last few years, the term DER has become more and more commonplace in the energy space. Most of us know that this three letter acronym (TLA, get it?) stands for Distributed Energy Resources, but what Distributed Energy Resources are might be a bit fuzzier....
Hot Topics at DistribuTECH 2018: The rise of DERMS, integrated interconnection and DER adoption planning
Every year we’re inspired at DistribuTECH, where in 2018 more than 11,000 participants from over 70 countries gathered in San Antonio to discuss the latest topics on grid modernization. For Clean Power Research and our customers, there was ample evidence that many of...

Hot topic: forecasting solar for grid integration
Grid-integration of distributed generation sources continues to be a hot topic for utilities and independent system operators (ISOs). Last month, the Utility Variable Generation Integration Group (UVIG) held its 6th annual workshop on Variable Generation Forecasting...
Tilt vs. flat-mount PV: does it really matter?
Have you ever wondered if PV system orientation really makes that much difference to the amount of power produced by a PV system? As the map below illustrates, the answer is typically yes, but to varying degrees. This ‘Energy Gains’ map depicts how tilting solar...
Top 2013 trends part 3: utility and ISO integration of high penetration PV
Over the past few weeks, we’ve plotted out emerging solar industry trends for the upcoming year, including solar soft cost reductions, and a re-examination of net metering. These first two topics are primarily about the financials of PV: reducing system costs and...
NREL turns to SolarAnywhere for NSRDB
Yesterday, the National Renewable Energy Laboratory (NREL) announced the newest release of the National Solar Radiation Database (NSRDB). The database is widely used by solar system designers, building architects and engineers, renewable energy analysts and others to...
SolarAnywhere® SystemCheck™ takes PV benchmarking to the masses
We’re pleased to be announcing an addition to our SolarAnywhere® product family today – SolarAnywhere® SystemCheck™. We’ve been hearing from our customers who own fleets of residential and small-commercial scale PV systems, or who provide PV monitoring services, that...
Gearing up for Solar Power International (SPI) 2012 in Orlando
SPI is next week in Orlando! Six of us will be there from our Kirkland, WA and Napa, CA offices. If you’re attending, please stop by Clean Power Research at booth #4058, right next to the “Energy Networking Station” in Hall B. Areas of emphasis for Clean...
Solar forecasting buzz at the ASES WREF Conference and other takeaways
Last week, the American Solar Energy Society (ASES) held its annual conference in Denver in conjunction with the World Renewable Energy Forum (WREF). Clean Power Research sent four team members to support the nine sessions and panels we participated in, and to staff...

CSI program wind-down doesn’t mean the end of solar in California
As the California Solar Initiative General Market program—the largest PV incentive program in the U.S.—winds down, an interesting solar landscape is emerging in California. A number of incentive programs large and small continue to support solar adoption in the state,...
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 shines bright on Mexico at Solar World Congress 2013
The International Solar Energy Society (ISES) Solar World Congress may be an international event, but this year, Mexico stole the show. Not only was it hosted by the Asociación Nacional de Energía Solar (ANES)—Mexico’s leading solar association—in Cancun this...
Reflections on SPI: 3 signs the solar industry is maturing
Each year, Solar Power International (SPI) gives us the opportunity to take stock of the U.S. solar industry. This year’s event, held in Chicago Oct. 21-24, was no different. The 2013 version of “North America’s premier business-to-business event for professionals in...
Growing solar beyond California: financial intelligence for every state
Solar is rapidly growing beyond California. As described in the Men’s Journal article “Why Now Is the Time To Go Solar,” this growth is being driven by the availability of inexpensive panels, tax breaks, and options to lease or buy PV systems. While a recent...
