Azimutis is a professional solar shade measurement and PV site survey tool. Measure shading and obstructions directly on site, build a horizon profile and assess their impact on the PV project during the site survey. From the field data captured on site, Azimutis evaluates solar access, shading losses and estimated energy production. But Azimutis goes beyond shade measurement. You can also measure usable roof area, position PV modules and obstructions, determine potential system size and compare different project scenarios before leaving the site. MEASURE SOLAR SHADING • Fast on-site shade measurement • Horizon profile and sun path diagram • Near and far shading analysis • Solar Access and sun path data • “No Shading” mode for unobstructed sites • Height simulation to assess changes in the shading profile CHECK WHAT CAN ACTUALLY BE INSTALLED • Measure usable roof area • PV module layout • Position modules and roof obstructions • Determine module count and potential system size • Inclinometer and compass for roof pitch and orientation • Compare multiple project scenarios ASSESS THE PV PROJECT ON SITE • Solar irradiance • Shading impact • Estimated PV energy production • Production losses • Financial and environmental indicators DOCUMENT AND EXPORT THE SITE SURVEY • Customizable PDF report • CSV horizon data for PVsyst workflows • TXT export for PVGIS workflows • HOR export for PV*SOL and HelioScope • Project management and synchronization Azimutis is designed for solar installers, PV contractors, technical sales teams, engineering firms, architects and solar professionals carrying out site surveys. The goal is to verify project assumptions against actual site conditions, obtain useful results while still in the field and prepare the next design stage without having to reconstruct the site survey back at the office. Azimutis complements your existing solar design, simulation and sales software. It provides the field data needed at the point where project assumptions meet actual site conditions.

Verdict

The call

The clearest difference is review sentiment: PV Calculator Lite Version at 100% against Azimutis's 50%. PV Calculator Lite Version also leads on in-app purchases (none vs 2) and iOS requirement (13.4 vs 18.0). Azimutis's advantage is update cadence (every 4 days vs every 10 days). On price, ads and device support there is nothing between them.
