This Android application gathers essential parameters about a solar installation from the user and from device sensors, then works with an inference engine on the server to deliver an output value prescribed by the environmental condition. It represents the practical optimal output deliverable by your system.
The app will help you determine the efficiency and health status of your solar power installation.
Our mathematical model for photovoltaic performance takes into account latitude & longitude, azimuth & tilt angle, brand & model of solar modules, irradiance & cell temperature, and time & date.
Wattminder is not responsible for any damages as a result of relying on the data presented by the app.
The usage of Solar Energy has increased recently, due to its advantages, mainly because it is a clean renewable source of energy, which its availability makes it ideal for local production of electric power.
The position of a PV panel affects its power generation. Thus, the panels should be positioned optimally for maximum efficiency.
THIS TOOL uses GPS to determine your location and the time of the day, than calculate the azimuth and the elevation of the sun. Having the sun's position calculated, your smartphone will guide you and show you how to position your panel for optimal solar energy generation.
3 operational modes available:
★ Now - The best position of the panel at the current time.
★ Year - The best position of the panel through the whole year.
★ Custom - You may choose the period for optimal power generation.
For best result, place your smartphone in a vertical position on your solar cell surface. The arrows pointing left and right indicate the pan rotation, while the up and down arrows suggest the tilt rotation. Note that the color of the arrows will change from red to green as you get closer to the desired location. We suggest to make gentle movements while the arrows are green until they disappear. When the light bulb turns on, you're on the spot! Now you can remove your smartphone from the panel, and get the most of your solar panel.

In just three easy steps, you can obtain radiation information for your desired location:
position your tablet/Smartphone as if it was a photovoltaic panel; when it is in the correct position, “print” the parameters and retrieve the data.
If you want to customize the parameters like location, orientation, or incline, you can do this by using the pencil shaped button next to each parameter. Once you have the data, you can share the data with your contacts or open it with other applications on your device.
The data contained in the app comes from either NASA or PVGIS (European Union), depending on your chosen location. PVGIS info is retrieved from this site: http://re.jrc.ec.europa.eu/pvgis/
If the data you requested has a location somewhere in Europe or Africa, then the data will come from PVGIS, and if the coordinates correspond to somewhere else on the planet, the data will come from NASA.
The radiation and the electric production data are out of our control and Irradia Energía is not responsible for the accuracy or availability of this information.
