Description

From the listing uploaded by “appupdater”.

Note: this is the trial version of SolarTester Pro (https://play.google.com/store/apps/details?id=com.optivelox.solartester2), some functions might be limited. For more details about SolarTester Pro please contact [email protected] SolarTester is a professional tool for the calculation and assessment of worldwide photovoltaic systems. It makes performance predictions and cost of energy estimates for grid-connected power projects based on installation and operating costs and system design parameters specified by the user. You can run a simulation and generate professional reports on generation, losses and financials. With SolarTester you can also make accurate real-time measurements of the solar irradiance components, not only global irradiance as with common pyranometers or solarimeters but also diffuse and reflected components. You can assess the current performance of a photovoltaic system and measure its efficiency. SolarTester can also display the current UV index (international standard measurement of the strength of the ultraviolet radiation) and allows you to take all the necessary precautions to protect yourself from sunburns, eye damage, skin aging or worst diseases such as skin cancer. Please, note that real time measurements require a special hardware add-on (SS02 sensor) connected to the audio jack of your smartphone. For more details about SS02 please see http://optivelox.50webs.com/DL_en/ss0x.htm Typical applications - Simulation of worldwide grid-connected PV systems - Meteorology, climatology, solar energy studies and building physics - Power assessment of PV systems - Assistance in improving the PV performance through reflected irradiance - Allows you to measure UV radiation and prevent skin damages Features - Internal worldwide irradiance database (NASA data) - Hourly estimation - Simulation of PV system with shading modeling - Sun path analysis - Provides a quick estimation of: annual/monthly electricity generation, optimal tilt/azimuth angle, payback period, levelized cost of electricity and much more... - Measurements of Global, Direct, Diffuse and Reflected solar irradiances - Measurements of UV index - Global and Direct irradiance datalogger - Generation of PDF reports - Projects can be saved in int/ext memory or shared - Supported languages: en,es,de,fr,it
