SolarTester

SolarTester is the professional solar energy assessment tool that transforms your Android device into a complete photovoltaic analysis platform. Whether you're designing grid-connected PV systems, conducting solar research, or optimizing existing installations, this app delivers accurate performance predictions and detailed financial insights for solar projects worldwide.

Plan and simulate PV systems with confidence. SolarTester leverages NASA's global irradiance database to model photovoltaic performance across any location on Earth. The built-in simulation engine accounts for system design parameters, installation costs, and real-world operating conditions—then generates hourly estimations and professional PDF reports covering generation forecasts, energy losses, and financial metrics. Optimize your system's tilt and azimuth angles, calculate payback periods, and determine levelized cost of electricity without leaving the app. Shading modeling ensures your projections reflect actual site conditions, while sun path analysis helps you visualize solar geometry throughout the year.

Measure and monitor solar radiation in real time. Unlike standard pyranometers, SolarTester captures the complete picture: global, direct, diffuse, and reflected irradiance components. This granular data lets you assess current PV system performance, calculate efficiency metrics, and identify opportunities to boost generation through reflected irradiance optimization. The built-in UV index monitoring (based on international standards) lets you track ultraviolet radiation exposure and take protective measures against sunburns, eye damage, skin aging, and serious conditions like skin cancer.

Work smarter with integrated tools built for solar professionals. Save and organize multiple projects in internal or external storage, then share results instantly with colleagues and clients. The global irradiance datalogger records measurements over time, supporting detailed performance analysis. Multi-language support in English, Spanish, German, French, and Italian ensures accessibility for international teams. All data syncs smoothly, allowing you to document everything from initial site assessment through post-installation verification.

This trial version includes core simulation and analysis features; real-time solar irradiance measurements require the optional SS02 hardware sensor (connected via your smartphone's audio jack). Ideal applications span grid-connected PV system design, meteorology and climatology research, solar energy studies, building physics analysis, and performance diagnostics.
