While solar designers have struggled with accuracy issues for years, Italy’s Fimer has finally stepped up with a solution. Their new PowerPHAST tool is changing the game for photovoltaic array sizing. It’s about time someone fixed this problem. The advanced simulation tool combines actual site data with customer behavior patterns to deliver scarily accurate predictions of how solar systems will perform in real life. No more guesswork. No more disappointed customers.
PowerPHAST runs exclusively on Fimer’s Aurora Vision cloud platform, making it accessible for designers working remotely. The tool’s database is massive. It calculates energy production using azimuth tilt parameters and estimates annual production capacity per square meter based on geolocation. Pretty fancy stuff.
Local irradiance calculations pull from both installation data and meteorological services, creating a complete picture of what to expect. Launched on February 6, 2026, the system even simulates self-consumption patterns throughout different seasons. Want to know how storage systems handle winter versus summer? PowerPHAST has you covered.
It compares alternative design scenarios too, so installers can show customers exactly why one configuration works better than another. Data doesn’t lie. Much like geothermal energy’s impressive 96% capacity factor, PowerPHAST’s simulations provide reliable performance metrics that customers can trust. For the tech nerds, there’s a LAB section displaying photovoltaic and current-voltage curves of the solar generator. Practical and informative. Designers can validate their choices before spending a dime on installation. That’s just smart business.
Reports are easily downloadable for project documentation—essential for keeping clients informed and installations on track. The tool stays current with Fimer’s evolving solar solutions, meaning designs remain cutting-edge. With operations in 26 countries worldwide, Fimer provides exceptional technical support to both installers and end users utilizing their monitoring tools.
Let’s be real. Solar design has been a frustrating guessing game for too long. PowerPHAST eliminates the gap between expected and actual performance. The result? Systems that deliver what they promise. No surprises, no disappointments. Just solar installations that work exactly as predicted. What a concept.
