8,760-Hour Annual Shade Simulation
SurgePV's solar shading software simulates shading for every hour of the year across your entire project site. As a complete pv shading tool, it identifies obstructions from trees, buildings, and adjacent structures — then optimizes panel placement to recover lost energy. Combine this with our full solar design workflow for end-to-end project planning.
Hour-by-Hour Analysis
Full-year simulation showing exactly when and where shadows fall on your panels - every hour, every day.
Sun Path Visualization
Interactive sun path diagrams showing seasonal solar angles and shadow patterns for any location on earth. Try our sun angle calculator to check angles for your site.
Obstruction Modeling
Model trees, buildings, chimneys, and nearby structures that cast shadows on your array throughout the year.
Color-Coded Irradiance Maps for Every Surface
Visualize solar irradiance across every roof face and ground surface. Find the optimal tilt and azimuth combination that maximizes energy harvest - before you place a single panel.
Irradiance Mapping
Color-coded irradiance maps for every roof surface to identify optimal tilt angle and azimuth orientation.
Surface-Level Analysis
Break down irradiance by individual surface sections - pinpoint exactly where shading losses are highest.
Placement Optimization
Use irradiance data to auto-position panels in the highest-performing zones on complex multi-pitch roofs.
P50/P90 Energy Reports Banks Actually Accept
Generate investor-grade energy yield reports with ±3% accuracy compared to field measurements. Reports include monthly and annual energy production, performance ratios, and detailed loss breakdowns - ready for financing. Feed results directly into our energy yield simulation for complete financial modeling.

What Solar Engineers Say
Our system performance predictions are now within 3% of actuals. SurgePV's shading analysis helped us recover 15% more energy on a 500kW project.
Luca Rossi
Lead Solar Consultant, MedSolar Italia · 500kW project
"The irradiance mapping saved us from a bad design on a complex commercial roof. We moved 40 panels and gained 12% more output."
Emma Larsson
Solar Project Designer, Nordic Energy, Stockholm
"P50/P90 reports that banks actually accept. We stopped using separate simulation tools entirely and saved $1,500/year per license."
Kenji Tanaka
Senior Solar Engineer, NipponSolar
What is solar shading analysis?
Solar shading analysis is the process of modeling how trees, buildings, and other obstructions block sunlight from reaching solar panels. SurgePV runs 8,760-hour simulations to calculate energy losses and optimize panel placement for maximum yield.
How accurate is AI-powered shading analysis?
SurgePV's shading analysis software is calibrated to within ±3% of field measurements. It models hourly sun paths across the full year, accounting for seasonal changes, obstruction geometry, and reflected light — producing bankable reports accepted by lenders.
Do banks accept software-generated shading reports?
Yes. SurgePV generates P50/P90 energy yield reports with detailed loss budgets that meet financing standards. These reports are accepted by banks and institutional investors in 18+ countries for project finance and due diligence.
Frequently Asked Questions
How accurate is SurgePV's shading analysis?
SurgePV delivers ±3% accuracy compared to field measurements, 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, chimneys, 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 with banks and institutional investors.
Does SurgePV include energy simulation?
Yes. SurgePV includes full energy simulation capabilities with ±3% accuracy, plus integrated design, proposals, and financials - all in one platform.
What is solar shading analysis software?
Solar shading analysis software models how obstructions like trees, buildings, and chimneys block sunlight from reaching solar panels. SurgePV runs hour-by-hour simulations across 8,760 hours per year, then generates color-coded irradiance maps and bankable energy reports that lenders accept.
How does shading analysis recover lost energy?
By identifying underperforming areas before installation, shading analysis lets designers relocate panels, adjust tilt, or remove problematic strings. SurgePV users report recovering 10–15% more energy per project by optimizing placement based on shade simulation data.
