PV Glare — an Underestimated Project Risk

Solar module reflections can dazzle like a mirror. This affects residents, drivers, pilots — and ultimately your project.

Approvals at Risk

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.

Avoid Costly Retrofits

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.

Defuse Conflicts Early

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.

Traffic & Aviation Safety

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.

Who is PV-GlareCheck made for?

Whether planning, assessment, or being affected — the software supports everyone who needs to understand glare impact.

Developers & Planners

Fast preliminary glare assessment already in the site and layout phase — before detailed planning and costs arise.

Experts & Assessors

An efficient evaluation tool for reflection and glare-time calculation as a basis for your own professional assessment.

Homeowners

Simulate in advance whether your own rooftop system could dazzle neighbors — and avoid conflicts before they arise.

Affected Residents

Assess a suspected glare from a nearby system in a comprehensible way — as a factual basis for a conversation.

and many more

Energy consultants, municipalities, authorities — wherever the glare impact of PV systems matters.

Everything for a Thorough Glare Analysis

Precise simulation results, professional visualizations, and intelligent filters — all in one application.

Glare Time Heatmap

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.

Blendzeiten-Heatmap

Reflection Map

All reflection directions visualized on Google Maps. See exactly where PV modules reflect — with color coding by frequency and optional time-point view.

Reflexionskarte

3D Perspective

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.

3D-Perspektive

Intelligent Filters

Filter results by intensity threshold, core glare (specular), sun overlap, vertical glare source height, and field of view. All charts update instantly.
