PVcase

PVcase is a Lithuanian solar project design software platform, founded in 2017 in Vilnius by David Trainavicius alongside a team of engineers with direct experience in solar project development. The product automates the most complex and time-consuming technical phases of solar design — from panel layout to shading analysis and energy yield calculations — drastically cutting the time solar developers need to go from concept to executable design. The company's funding path reached a turning point in July 2023, with a $100 million Series B led by Highland Europe and Energize, with participation from existing investor Elephant, bringing total funding to approximately $123.6-124 million across four rounds. It was one of the largest rounds ever raised by a Lithuanian startup, a signal of international investor confidence in the growth potential of vertical software for the solar industry. As of April 2026, PVcase's headcount stood at 343 employees, reflecting the scale the company reached after its Series B round, although no new public funding announcements have surfaced for 2025-2026. The company continues operating in the solar design software market, structurally supported by the global expansion of installed photovoltaic capacity, where design automation tools are a critical factor in reducing development costs and accelerating time-to-commissioning for new plants, amid growing margin pressure on solar developers.
