13 helioscope pvpmc 2017v4

  1. 1. HelioScope Updates May 2017 1
  2. 2. About 2 • Cloud-based software • Integrates system design and performance modeling • Similar math and accuracy to PVsyst • .PAN file compatibility • Transposition models • Cell temp models • Temp coefficients • Exception: component-by-component circuit simulation
  3. 3. About 3 • Considered bankable by IEs, banks, owners, and developers • Residential, commercial, and utility- scale • 600k projects to date in 160 countries • Taught at universities across the world
  4. 4. Updates to HelioScope Performance Modeling • Spectral adjustment for CdTe modules • Next generation shading engine Engineering Process • Team management & design defaults • Single line diagram • Financial integration (Energy Toolbase) • Standardized shade reports Design Environment • Interactive 3D environment • Field segment heights • East-west racking • Automatic stringing based on ASHRAE data • Dual-MPPT inverters • LiDAR • Faster layout algorithm 4 Oct 2016 May 2017
  5. 5. Spectral Adjustment • First Solar Spectral Adjustment 𝑀 ≈ 1.266 − 0.091𝑒1.199 ∙ (𝑝 𝑤𝑎𝑡+0.5)−0.21 𝑀 = spectral shift 𝑝 𝑤𝑎𝑡 = precipitable water • Default for CdTe modules • Weather Data - the biggest barrier – Only 10% of >300k datasets in HelioScope contain 𝑝 𝑤𝑎𝑡 – 𝑝 𝑤𝑎𝑡 calculated from Relative Humidity or Dew Point Temp for majority of datasets 5 Image curtesy of Lee, M. et al, PVSC 2015
  6. 6. Updates to HelioScope Performance Modeling • Spectral adjustment for CdTe modules • Next generation shading engine Engineering Process • Team management & design defaults • Single line diagram • Financial integration (Energy Toolbase) • Standardized shade reports Design Environment • Interactive 3D environment • Field segment heights • East-west racking • Automatic stringing based on ASHRAE data • Dual-MPPT inverters • LiDAR • Faster layout algorithm 6 Oct 2016 May 2017
  7. 7. Next Generation Shading Engine • Unified math behind several shading subsystems • Performance Improvements – Replaced “infinite-sheds” heuristics – Calculates diffuse individually for each module by sampling >200 points across the celestial vault considering the full scene • Native C code – Optimized from the ground-up for the solar use case – Fast! 7 Image curtesy of Rehman et al, 2015
  8. 8. Standardized Shade Reports • Accurately model shade without on-site measurements • All calculations are module-level and site-specific • Meets reporting requirements re Solar Access, TOF, TSRF • Approved by incentive authorities in CA, NY, OR, TX, RI, NJ, and more 8
  9. 9. Revised Layout Algorithm Up to 50x faster computational speeds 9
  10. 10. Financial Integration with 10
  11. 11. DEMO http://help.helioscope.com/article/14-5-minute-overview https://www.helioscope.com/webinars 11
  12. 12. Product Roadmap • Financial and utility rate engine • Customer-facing proposal tool • Single-axis trackers • and many more; see blog.helioscope.com for the latest 12
