About this app

Maximize your solar energy harvest with precision.

Whether you are a solar installation professional or a homeowner looking to optimize your rooftop system, this app provides the accurate, data-driven insights you need to get the most out of every sunbeam.

Key Features:
Scientific Accuracy: Powered by the European Commission’s PVGIS (Photovoltaic Geographical Information System), our calculations leverage over 18 years of historical climate and solar radiation satellite data for your exact location.

Optimal Tilt & Orientation: Stop guessing. Get the recommended tilt angle and orientation optimized for your specific site, ensuring maximum year-round energy production.

Real-Time Hardware Integration: Use your phone’s built-in sensors (Inclinometer & Compass) to align your panels physically with professional precision.

Intuitive Interface: Designed for speed and clarity. No complex spreadsheets—just the data you need, right when you need it.

Cardinal Direction Guidance: Easily interpret optimal azimuths with clear, human-readable cardinal directions (e.g., South-Southwest) alongside precise degree measurements.

Why trust our calculations?
Unlike generic calculators, our app accounts for site-specific micro-climates, ensuring that your installation is perfectly tuned for your environment. We bridge the gap between complex satellite climate data and field-level installation requirements.

Perfect for:
Solar EPC companies and field technicians.
DIY solar enthusiasts and homeowners.
Sustainability-focused building managers.

Permissions Notice:
