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.

The PV*SOL app helps homeowners and system planners in making the decision for a PV system. In four simple steps, the app determines the necessary data and calculates the possible solar output:
1. Smart with Smartphone: you can type in or determine the orientation and pitch of the roof with the help of the sensors in your mobile phone.
2. Opt for one of three types of modules: monocrystalline, polycrystalline or thin film.
3. Enter the desired approximate size of the module area or the peak power.
4. The location of your PV system determines the possible solar yield. The PV*SOL app uses the Valentin Software climate data database.
If your mobile phone has GPS, your location will be shown on a map. Otherwise, enter the name of your location.
The characteristics of your PV system are calculated with the climate data for this location.
The simulation uses the PV*SOL calculator on our server to calculate the system quality and yield with the following results:
- Annual irradiation (kWh/a)
- Annual irradiation on the tilted surface (kWh/a)
- Feed-in (kWh/a) - depending on the feed-in tariff, you can easily convert this value into the annual feed-in payment
- Performance ratio
Send your results by Bluetooth, e-mail or text, depending on which options your mobile phone/mobile phone contract provides.
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.

The use of this App has technical limitations because of the conditions while using Bluetooth. These limitations are inherent to the App and have nothing to do with the SMA
Switch on your bluetooth.
Hit the menu button and select 'Settings', then 'Inverters' to list your current inverters.
To add new ones select 'Scan for devices'.
If new ones have been found you can select one of them, enter its password, select the model and click on 'Save'.
Go back to the settings screen to select this new inverter as the current one.
Next hit the menu button and select 'Connect inverter' to begin reading the production data of the current day.
You can use a sideways swipe gesture to access the daily production, total production and lastly a screen with detailed info about the inverter.
Swipe up or down to change the day, week or month.
If your inverter doesn't broadcast itself you can manually enter the inverter info with 'Manual setup'.
Select 'Date' to select the current day. If no values are found the screen will be black and you ought to connect to your inverter.
To switch to another inverter select 'Settings' and choose the one you want.
To be able to export to pvoutput.org go to settings and select 'PVOutput'. Click the 'Add' button to add your pvoutput specific data. Be careful with that api key, it is error prone. Next click save and when going back to the settings screen you must select a current pvoutput system.
I noticed that exporting to pvoutput is unfortunately not allowed beyond 2 weeks in the past. :-/
You can also export the current day to a csv file. I took over the format used by SMA. The files are stored in /Android/data/be.geek.smandroid/files/.
This has been tested with a HTC Desire running Gingerbread 2.3.3 and a SMA Sunny Boy 2000HF-30 inverter.
If you have one of those select '3000TLHF' as model.
Be aware that after a few weeks of daily intake your application's data size can grow considerably. Use the 'Delete' button in the inverter detail screen (or use the 'Clear data' button from app management).
Or use the Delete menu option from the main menu.
You can switch to an alternate view from Settings. Select 'Current view' to choose between a dayly (default), weekly or monthly view.
If you choose a weekly or a monthly view you can now retrieve data from the displayed date range. Be aware that reading an entire month can take a considerable time.
The 'Live' option allows you to read inverter data continuously. Select the current day first (I'll sort it out automatically in a next update). The update interval is specified in Settings by selecting 'Current live delay'.
If you have a pvoutput system it will then export to this.
Important note for those with problems: this is essentially a java port of sma-bluetooth.
Consider joining the sma-bluetooth mailing list if you're having problems with your type of inverter. If you get helpful answers you can relay them back to me and I'll see what I can do.
Your android device and inverter must first be paired before being allowed to connect. Usually a notification will pop up the first time you try to connect allowing you to enter the pairing password.
Some users have been unable to connect with their HTC Desire HD devices with v2.3.5. I will try to trace the source of this problem.
Apparenly the inverter code for 5000TL-21 is still wrong. Could somebody confirm this?
The calculations are based on the equivalent lumped electrical model of four parameters with a correction on the value of the module’s internal resistant.

Note1: The scientific equations used for calculating temperature effect on the PV modules have demonstrated in literature to provide optimal results for poly/mono crystalline based modules, but no reference for thin film modules is purveyed.
Note2: The app calculates the theoretical maximum for installations with solar tracking system, considering that the modules are always oriented towards the sun. Accordingly, the real production for fixed installations will always be smaller than the production estimated by the app.
Languages supported: English, French, German, Spanish and Catalan.
LITE version has several limitations. Get the full version and obtain the following features:
1) No advertising.
2) No limits number of installations.
