WHO WE ARE

Our Founding Story

HelioVolta was founded by James Nagel, PE, and David Penalva, two NABCEP-certified PV system inspectors and field engineers. They observed the rising trend of quality issues in renewable energy projects since joining the solar industry in the 2010s.

They believed rapid industry growth, inconsistent training, and evolving technology led to preventable safety and reliability failures. Their two-part solution combined independent technical services and SolarGrade, a purpose-built software platform for field operations and asset management.

HelioVolta Today

Since launching in 2021, demand for HelioVolta’s services and SolarGrade software has grown rapidly. In 2025, SolarGrade became its own affiliated company, continuing close collaboration with HelioVolta, whose field teams use the software and provide ongoing feedback to refine the platform.
