Founding the Company
Thomas Hoff, Ph.D., a Stanford graduate with a passion for renewable energy and photovoltaic (PV) economics, founds Clean Power Research as a research consultancy.
From Research to Software
A neighbor asks Tom, “What is the value of solar to me?” To answer, Tom develops Clean Power Estimator® (now WattPlan®), an online PV calculation tool that is rapidly adopted by utilities and PV manufacturers.
To alleviate the challenges of paper-based incentive application processes in the face of rapidly growing volumes, Clean Power Research launches PowerClerk. Designed specifically for utilities, PowerClerk automates and optimizes application workflows, reducing costs and processing time.
Software Services Group Is Formed
PowerClerk’s success leads to the creation of the company’s Software Services Group and marks a new focus on delivering adaptable, scalable and secure cloud software solutions to the energy industry. Jeff Ressler, a 10-plus year veteran of Microsoft, joins the company to run the new team, and the Kirkland, Wash., office opens.
A partnership with the University at Albany (SUNY) and Dr. Richard Perez leads to the development of SolarAnywhere® Data, bankable irradiance data that is at the core of the current suite of solar data and intelligence offerings
New PV Variability Method
In a paper published in the ISES journal Solar Energy, Clean Power Research shows that the relative power output variability of distributed PV fleets can be quantified. This insight helps in the management of existing PV fleets or designing new ones.
SolarAnywhere® FleetView® Launches
SolarAnywhere FleetView launches to address the need for utilities and ISOs to cost-effectively and reliably integrate distributed PV into the grid. This allows for higher PV penetration and reduces costs for utilities, ratepayers and PV system owners. A major step toward delivering software for a clean-powered planet is achieved.
PowerClerk® Interconnect Launches
Funded by a U.S. Department of Energy SunShot Initiative Incubator award, PowerClerk® Interconnect launches to help reduce solar soft costs by taking formerly paper-intensive interconnection processes online. The new PowerClerk platform provides utilities more control over their interconnection and DER program workflows to streamline processes for everyone involved.
WattPlan is developed to enable utilities to cost-effectively engage customers with highly-personalized answers to energy questions such as: “Is solar right for me?” WattPlan® incorporates newly available information such as interval data from smart meters and innovations like rate optimization to set a new standard for user-facing energy modeling tools.
Clean Power Research celebrates 20 years providing innovative, efficient and adaptable software solutions that are helping to solve the energy industry’s most challenging problems.
Data Visualization in PowerClerk®
A new Dashboards feature for PowerClerk launches that enables program administrators to support program transparency with built-in reporting and data visualization capabilities—no export, programming or third-party tools required.
More Accurate Solar Irradiance Data
SolarAnywhere® consistently derives more accurate solar irradiance data than ever before from GOES-17 satellites.
Building on Core Technologies
SolarAnywhere® deploys numerous updates building on the same core technologies that have made SolarAnywhere the most trusted source for bankable solar resource data.
