While solar designers have long struggled with clunky simulation tools, Italy-headquartered inverter manufacturer Fimer just changed the game. The company launched PowerPHAST on February 6, 2026, and frankly, it’s about time someone fixed this problem.
This photovoltaic array sizing tool, distributed through Fimer’s cloud-based Aurora Vision platform, combines real site data and customer behavior with advanced simulations. No more guesswork. Just eerily accurate predictions.
PowerPHAST isn’t your average solar calculator. It models expected performance of photovoltaic and storage systems with precision that’ll make engineers weep with joy. The tool aligns system design with actual energy production, consumption, and storage over time. Solar panels don’t perform in a vacuum, and PowerPHAST knows it.
PowerPHAST delivers eerily precise PV modeling that finally acknowledges real-world conditions instead of theoretical ideals.
What makes it special? For starters, it has an extensive solar panel database. It calculates energy production based on azimuth and tilt. It uses site geolocation for expected irradiation. The tool also provides local irradiance calculations derived from installation and meteorological data. It’s like having a solar scientist in your pocket, minus the lab coat and awkward small talk.
The simulation capabilities are where things get interesting. Self-consumption and storage system self-sufficiency across yearly periods? Check. Easy-to-download reports? Yep. Data-driven customer information? You bet. All accessible via Aurora Vision.
Fimer, owned by MA Solar Italy, isn’t new to the solar game. With production sites in Italy and India and a global presence, they know their stuff. The tool comes at a perfect time as photovoltaic costs have dropped 82% in the past decade, making solar increasingly viable worldwide.
And they’re not stopping with PowerPHAST. The tool is designed to grow over time, expanding features and platform availability. The company will be showcasing this innovation at KEY 2026 event in Rimini, where FIMER experts will be available for in-depth discussions.
