American-Made Solar Prize

The American-Made Solar Prize is a $3 million competition designed to revitalize solar manufacturing in the United States. Teams will be selected from a diverse applicant pool of entrepreneurial students, professors, small-business owners, company staffers, researchers at the U.S. Department of Energy’s (DOE’s) National Laboratories, and anyone else based in the United States with a potentially marketable solar technology solution. This challenge requires competitors to make progress on a condensed timeline, form private-sector partnerships, and secure investments to make their ideas a reality.

On September 24, 2019, Round 3 of the American-Made Solar Prize was launched. To participate, competitors must identify a critical challenge related to American solar manufacturing competitiveness, create a proof of concept, and secure a partner to test a prototype. Competitors will participate in demonstration days, where they will pitch their ideas. At these national events, a panel of expert reviewers will evaluate competitors based on the quality of their solution and the progress made during the contest period.

On February 11, 2020, 20 teams representing 11 states were selected to receive $50,000 and move on to the next phase of the competition. Their concepts are grouped into two categories: photovoltaics (PV) and systems integration.

On December 4, 2020, two winning teams were announced at a live virtual event. Each team received $500,000 in cash and $75,000 in vouchers to use at the National Laboratories and other qualified fabrication facilities. The winners are:

Maxout Renewables (Livermore, CA) — This team developed the Evergrid, an appliance powered by a fly-wheel that can turn a residential solar installation into a microgrid that keeps delivering power during a grid outage while the sun is shining. The Evergrid also stabilizes the home microgrid by providing power balancing capacity when appliances like refrigerators cycle on and off.

Wattch Inc. (Atlanta, GA) — This team developed cost-effective hardware and combined it with secure, scalable software to make a solar monitoring platform to help commercial and industrial PV plants increase operational efficiency. The platform can provide predictive maintenance schedules to decrease downtime, has a universal dashboard that lets PV fleet owners and operators observe the performance of all their systems, improve remote and automated diagnostics, and better model a plant’s lifetime energy yield.

American-Made Solar Prize Round 3 Finalists and Semifinalists


Durable Antireflective and Self-Cleaning Glass 
Location: Pittsburgh, PA
Project Summary: This team’s wet-etching process creates nanostructures on the front of solar panel glass, providing enhanced antireflection, anti-soiling, and self-cleaning functions for PV panels. Corning, a company specializing in glass and other materials, will help the team develop the process and demonstrate the durability of the textured glass.

Pursuit Solar, LLC (Finalist) 
Location: Denver, NC
Project Summary: This team’s passive solar tracker enables panels to capture more solar energy without motors, controls, or external power. A small concentrating mirror system heats paraffin wax, which rotates the panels to track the sun when they’re properly positioned. 

Location: San Diego, CA
Project Summary: This team has developed a contactless imaging tool that detects water in solar modules. The tool can be used as both a static measurement device during the manufacturing process and a mobile measurement device for field monitoring.

Remotely Deployed Solar Arrays
Location: Charlottesville, VA
Project Summary: To provide options for energy production on infrequently used surfaces like driveways and parking lots, this team designed a portable system in which solar panels rise out of a storage container and retract when the land is needed for other uses.

Renu Robotics Corporation (Finalist)
Location: San Antonio, TX
Project Summary: This team is developing an autonomous electric lawnmower for utility-scale solar power plants that can maintain hundreds of acres a month without human interaction.

Simple-Assembly Storage Kit
Location: San Antonio, TX
Project Summary: This team is developing a “solar tree” kit that doesn’t need to go on a roof and is easy to install.

Solar for Snow 
Location: Duluth, MN
Project Summary: This team is developing silicon solar panels designed to work in areas that get a lot of snow and ice. A frameless panel will shed snow naturally, and a heating element will melt snow and ice.

TrackerSled (Finalist)
Location: Chicago, IL
Project Summary: This team is developing a movable single-axis tracker solar array for farms that can be towed around rotating crop fields on its pontoon skis. The array’s mobility will help farmers rotate their cash crop and cover crop fields, improving soil health, income, and power generation.

Transparent Polymer Barrier Films for PV 
Location: Bristol, PA
Project Summary: This team will develop and commercialize advanced transparent back and front sheets for bifacial PV modules.


Affordable Local Solar Storage via Utility Virtual Power Plants
Location: Parker, TX
Project Summary: This team is a veteran-owned business that’s developing a sealed-enclosure, whole-home transfer switch for inverters as a cheaper, simpler alternative to typical emergency power backup panels. The team will also implement standardized communication protocols so utilities can interact with the inverters.

Allbrand Solar Monitor
Location: Detroit, MI
Project Summary: This team is developing a universal monitor for residential PV systems that communicates with any microinverter, giving installers flexibility during installation or over the lifetime of the PV system.

Democratizing Solar with Artificial Intelligence (AI) Energy Management 
Location: Houston, TX
Project Summary: This team is combining a thin-film solar panel and smart battery with AI software for home use. The software tracks a user’s production and storage data to optimize home energy bills.

Enertronics, Inc. (Finalist)
Location: Blacksburg, VA
Project Summary: This team is developing a high-voltage, direct current (DC) power optimizer small enough to be built into a module's junction box.

infiniRel Corporation (Finalist)
Location: Santa Cruz, CA
Project Summary: This team developed a patented hardware/software system that monitors solar inverters while they’re operating to detect component deterioration as well as software control issues.
