Our online tool calculates reflections, glare times, and intensities of photovoltaic systems. Create professional glare analyses directly in your browser — no installation, no waiting.
Our simulation tool supports all mounting types — from rooftop to tracker.
Roof-parallel mounting & tilted on flat roofs
BIPV, vertical facade systems & balcony PV
Large solar parks & agri-PV
Single & dual-axis tracking systems
Solar module reflections can dazzle like a mirror. This affects residents, drivers, pilots — and ultimately your project.
Many approval processes require evidence on glare impact. An early analysis shows whether your site is critical — before the authority asks or an already built system has to be modified.
Anti-glare films, changed module tilts, or even dismantling rows: Retrofit measures cost many times more than planning costs. A simulation before construction reveals problems before they become expensive.
Glare from PV modules regularly leads to neighbor complaints. A transparent glare analysis creates clarity early on for residents, municipalities, and authorities — and protects your project reputation.
PV systems near roads, railways, or airports require special care. Glare can endanger drivers and pilots. Assessments for these use cases are often legally required.
Whether planning, assessment, or being affected — the software supports everyone who needs to understand glare impact.
Fast preliminary glare assessment already in the site and layout phase — before detailed planning and costs arise.
An efficient evaluation tool for reflection and glare-time calculation as a basis for your own professional assessment.
Simulate in advance whether your own rooftop system could dazzle neighbors — and avoid conflicts before they arise.
Assess a suspected glare from a nearby system in a comprehensible way — as a factual basis for a conversation.
Energy consultants, municipalities, authorities — wherever the glare impact of PV systems matters.
Precise simulation results, professional visualizations, and intelligent filters — all in one application.
See at a glance when and how long glare occurs — for every day of the year, for every observation point. The heatmap shows glare times by time of day and date, color-coded by intensity.
All reflection directions visualized on Google Maps. See exactly where PV modules reflect — with color coding by frequency and optional time-point view.
The equirectangular projection shows PV areas, reflection zones, and the sun path from the observer's perspective. With zoom, sun display, and intensity-coded coloring.
Filter results by intensity threshold, core glare (specular), sun overlap, vertical glare source height, and field of view. All charts update instantly.
One standard price per project. Add-ons only when you actually need them.
30 simulation runs included
Only add what you really need — both are optional and independent of the per-project base price.
Book 30 additional simulation runs for an existing project.
