On this episode of the Soliverse Podcast, Peter sits down with David Spieldenner from Terabase Energy, to expose the massive bottlenecks holding solar back—and why smarter performance modeling might be the key to unlocking the next Terawatt.

David doesn’t hold back as he makes the case for PlantPredict over legacy tools like PVsyst, and highlights why accuracy isn’t enough—realism is what developers, EPCs, and banks really need.


They cover:


⚠️ Why PVsyst is holding the industry back

🧠 Why “realism” > “accuracy” in yield estimates

🔁 How sub-hourly and 3D modeling reshape performance forecasts

🔋 Why terrain-following trackers can actually boost energy yield

📈 How hybrid plants and dispatchable renewables will reshape grid planning

📊 What banks, IEs, and EPCs really need from energy modeling tools

🚀 Why Terabase is betting on AI, automation, and integrated design-to-SCADA workflows

🧩 What most solar designers miss when modeling plant performance


David also shares an exclusive offer on PlantPredict + PV Radar bundles and reveals why data centers and the AI boom are pushing solar innovation into overdrive.
