String Infrastructure, Hourly Tariffs, Sun Path
String infrastructure models inverter constraints, hourly tariffs reflect time-variable pricing, and a sun path simulation maps yearly shadow movement.
String Infrastructure
A fully integrated string infrastructure brings detailed electrical modeling into the project design flow. Define and visualize strings directly on the roof, group panels into strings and assign them to MPPTs, simulate real inverter constraints such as voltage and current limits, track cable routing, lengths, and electrical values in real time, and receive instant warnings for invalid configurations. The system calculates IV curves at both string and MPPT level, allowing solarVis to determine the optimal operating point within inverter limits for each hour of the year. This delivers significantly more accurate production simulations and feasibility outputs, moving solarVis beyond layout-based design into true system-level engineering.
Module-Level Shading & Irradiance
Shading analysis now extends from roof surfaces down to individual PV modules. Visualize irradiance on both roof faces and panels, observe real-time color changes based on tilt, orientation, and placement, analyze detailed irradiance data dynamically, and trigger instant recalculations when panel conditions change. Even small design adjustments now directly impact module-level production insights, making it easier to identify underperforming panels and optimize system layout with greater precision.
Sun Path Simulation
An interactive sun path simulation enables time-based analysis of solar exposure. Simulate the sun's position at any time, observe shadow movement across the roof and surroundings, analyze seasonal differences such as summer and winter angles, and evaluate solar exposure dynamically. Combined with real-time shading visualization, you can see exactly when and where shading occurs throughout the year and make sharper decisions on layout, orientation, and system efficiency.
DXF Export
Export the complete solar design as an industry-standard DXF file directly from the Panel Placement and Inverter Selection page. The exported file is fully compatible with tools like AutoCAD and DraftSight, allowing seamless integration into existing engineering workflows.
Hourly Time-of-Use Tariffs
Tariff modeling now supports hour-by-hour electricity pricing instead of flat-rate assumptions. Define hourly or time-band unit prices, configure separate day, peak, and off-peak tariffs, reflect the real cost of consumption based on when it occurs, and analyze cost differences between peak and off-peak hours in detail. The capability ships in response to time-variable tariff regulations now rolling out in markets such as Türkiye, where hourly net metering takes effect on 1 May 2026, and applies wherever electricity is priced by time of day. Energy cost simulations become significantly more realistic, raising the accuracy of feasibility outputs and proposal calculations.
