- 1. PlantPredict : Solar Performance Modeling Made Simple
- 2. PLANTPREDICT: SOLAR PERFORMANCE MODELING MADE SIMPLE Reviewed by: • Generate quick, contract-grade predictions via a streamlined user interface • Designed specifically for utility-scale solar — Sub-hourly and multi-year predictions — Direct weather download — Built-in spectral correction — Cloud-based application • Independently reviewed and benchmarked against more than 1 GW of operating facilities
- 3. THE BENEFITS OF PLANTPREDICT • Reduce prediction time by up to 75% — Easy to learn, short learning curve • End-to-end utility-scale modeling — Built-in MV and HV transformers, Tx lines — Built-in availability and LGIA losses — No need for pre- or post-processing • Pre-loaded with industry standard weather, module, and inverter files • Optimize your design with “Clone” and “Quick Edit” • Cloud-hosted for ease of sharing and data security

Hinweis der Redaktion
- All modeling algorithms visible Easy to clone and compare predictions Regularly updates according to new industry technologies Cloud-based for easy sharing and enhanced data security Cloud security – data is safe if you lose your computer Can share predictions within or outside company, as desired Built-in weather download functionality Industry supported Validated by IEs
- By running quick, accurate predictions, your engineers can use their time doing real work instead of spending hours clicking around in clunky software. PlantPredict is so easy to use, by the end of this webinar I have full confidence that if you know how a solar plant works, you can run a model in PlantPredict. With everything you need for a utility-scale prediction, there is no longer a need for Excel workarounds for spectral modeling, unavailability, transformers, transmission lines, or any complex plant architecture. It comes pre-loaded with hundreds of industry standard files, and we have made it easier than ever to import files from your desktop or other tools With the super-handy “Clone” and “Quick Edit” features, you can infinitely tweak and optimize your plant for tilt angle, row spacing, or any desired parameter PlantPredict is hosted entirely on the cloud, so your data is completely secure and off your desktop. The added benefit is that you can easily share files and predictions within your company, without having to export and email any files!
- How long did it take to run the 100 predictions?
