UAB PVCase
Our vision is to accelerate global transition to clean energy. Renewable energy is set to overtake coal and gas by the end of 2024 with solar energy being the key driver of this transition. Although it evolves faster than wind and hydro due to the falling development costs, further solar PV technological innovation along the entire value chain is needed to meet the growing demand. Despite considerable resources already invested in the solar market, the solar engineering industry has struggled to maintain the pace and is lacking significant digitization. PVcase is determined to play a vital role in this transformation. By connecting the entire solar planning workflow, our solutions empower companies to make data-driven decisions with confidence when optimizing designs and assessing the viability of commercial and utility-scale power plants.
