Round 3 Go! Demo Day

The American-Made Solar Prize Round 3 teams have been working tirelessly over the past year preparing their technologies for the competition finale: Go! Demo Day. Since learning of their status as Round 3 finalists in July, these 10 teams have identified pilot test partners and used continual customer and stakeholder feedback to substantially advance their solutions from proof-of-concept to prototype.

Now, these innovators will present their products to a panel of expert reviewers one last time in the hopes of becoming a Round 3 winner.

Round 3 Go! Demo Day will take place on Dec. 3-4, 2020, in tandem with an industry networking event and Round 4 semifinalist announcement. This virtual format includes:

  • Thursday, Dec. 3: teams participate in a private Q&A session with a panel of expert reviewers.
  • Friday, Dec. 4: a solar professionals networking event, including the live Round 3 winner and Round 4 semifinalist announcements.


The Solar Prize team invites friends, family, peers, industry experts, and anyone interested in solar innovation to join the U.S. Department of Energy Solar Energy Technologies Office and the National Renewable Energy Laboratory on Friday, Dec. 4, at 1 p.m. ET for the virtual networking event and live winner announcement. Energy Department leadership will announce the two final winners of the Solar Prize Round 3, each earning $500,000 in cash prizes and $75,000 in support vouchers, as well as the Round 4 semifinalists.

teams listed by alphabetical order


Team: Enertronics Inc.
Technology: Low-Cost Parallel-Connected DC Power Optimizer
Location: Blacksburg, VA
Contact: Don Collins of Enertronics
Project Summary: This team is developing a high-voltage, direct current (DC) power optimizer small enough to be built into a module junction box.
Pitch Video:
Team: infiniRel Corp.
Technology: Inverter Health Scan
Location: San Jose, CA
Contact: Bert Wank of infiniRel
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.
Pitch Video:
Team: Maxout Renewables
Technology: Evergrid: Keep Solar Flowing When the Grid Is Down
Location: Livermore, CA
Contact: Kirsten Pace of Maxout Renewables
Project Summary: This team developed a cost-effective system that turns a residential solar installation into a microgrid that can keep power on during a grid outage.
Pitch Video:
Team: Pursuit Solar
Technology: Pursuit Solar - More Power, Less Hassle
Location: Denver, NC
Contact: Eddie Bugg of Pursuit Solar
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.
Pitch Video:
Team: Renu Robotics Corp.
Technology: Robotics Changing the Landscape for Solar Farms
Location: San Antonio, TX
Contact: Tony Padgett of Renu Robotics
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.
Pitch Video:
Team: Shine
Technology: JuiceBox: Integrated Solar Electricity for Americans Transitioning out of Homelessness and Recovering from Natural Disasters
Location: Claremont, CA
Contact: Solomon Olshin of Shine
Project Summary: This team is developing a small, lightweight, low-cost PV system with battery storage that does not require technical expertise to install, making it suitable for transitional homes and emergency management response.
Pitch Video:
Team: TrackerSled
Technology: TrackerSled
Location: Chicago, IL
Contact: Lawrence Kearns of TrackerSled
Project Summary: This team is developing a mobile solar array for farms that uses tractors mounted on pontoon skis to tow two digitally controlled single-axis solar trackers. The trackers follow the sun’s movement to capture sunlight on solar panels. The array’s mobility will help farmers rotate their cash crop and cover crop fields, improving soil health, income, and power generation.
Pitch Video:
Team: Uplift Solar Corp.
Technology: Embedded, Multi-Function Maximum Power Point Tracker (MPPT) for Smart Modules
Location: Las Vegas, NV
Contact: Darius Roberts of Uplift Solar
Project Summary: This team is developing a chip that is both a direct-current converter and an MPPT that can be embedded in a module. It will have a microprocessor that enables power line communication, ensuring module compliance with code updates.
Pitch Video:
Team: Verify Energy Inc.
Technology: Powerfly: A Plug-and-Play Solar Monitoring Device
Location: Berkeley, CA
Contact: James D’Albora of Verify Energy
Project Summary: This team is developing a self-powered device for utility-scale PV plants that monitors communications by combining the data logger, cellular modem, and data plan.
Pitch Video:
Team: Wattch Inc.
Technology: Beyond Monitoring – Next Gen Software and Hardware
Location: Atlanta, GA
Contact: Alex Nussey of Wattch
Project Summary: This team combines cost-effective hardware with secure, scalable software to deliver insights and increase operational efficiency for PV plants. This will result in predictive maintenance schedules that lower downtime, improve remote and automated diagnostics, and better model a plant’s lifetime energy yield.
