8,760-Hour Annual Shade Simulation
SurgePV simulates shading for every hour of the year across your entire project site. Identify obstructions from trees, buildings, and adjacent structures — then optimize panel placement to recover lost energy.
Hour-by-Hour Analysis
Full-year simulation showing exactly when and where shadows fall on your panels.
Irradiance Mapping
Color-coded irradiance maps for every roof surface to find optimal tilt and azimuth.
Sun Path Visualization
Interactive sun path diagrams showing seasonal solar angles and shadow patterns.
Obstruction Modeling
Model trees, buildings, and nearby structures that cast shadows on your array.

P50/P90 reports that banks actually accept. We stopped using PVsyst entirely and saved $1,500/year per license.
Frequently Asked Questions
How accurate is SurgePV's shading analysis?
SurgePV delivers ±3% accuracy compared to PVsyst, validated across hundreds of real-world installations. The analysis accounts for hourly sun position, nearby obstructions, and seasonal variations.
Can I model obstructions like trees and buildings?
Yes. You can add trees, buildings, and other structures to your 3D model. SurgePV will calculate their shadow impact on your array for every hour of the year.
Do banks and investors accept SurgePV energy reports?
Yes. SurgePV generates P50/P90 bankable energy reports that meet financing standards. Many EPCs have successfully used these reports for project financing.
Can I replace PVsyst with SurgePV?
Yes. SurgePV includes comparable energy simulation capabilities with ±3% accuracy, plus integrated design, proposals, and financials — all in one platform.
