Solar Spotter & PV Calculator

Solar Spotter & PV Calculator is a complete solar planning and calculation app designed for homeowners, solar installers, engineers, and anyone interested in solar energy.

Whether you're installing a new rooftop solar system or improving an existing setup, this app helps you adjust panel direction, find the right tilt angle, estimate system size, and better understand potential energy production.

Make informed solar decisions using clear data and practical tools.

☀️ PRECISION SOLAR SPOT & ALIGNMENT

Incorrect panel direction can reduce solar production.

Using device sensors and real-time GPS location data, the app calculates:

• Current orientation (azimuth)
• Tilt angle (inclination)
• Latitude & longitude
• Optimal south-facing direction
• Recommended tilt based on your location

Values update instantly as you move your device.

Better alignment can help improve energy production and reduce potential energy loss over time.

🌞 SUN PATH & SHADOW TRACKER

Even small shadows can impact panel performance.

Visualize:

• Real-time sun elevation & azimuth
• Sunrise, sunset & solar noon
• Golden hour & twilight timing
• Shadow length & direction

Use satellite map view with location pin and shadow direction indicator to plan better panel placement.

Avoid common installation positioning mistakes.
