 # solXpect
 
-solXpect forecasts the output of your solar power plant
+solXpect is an app that forecasts the output of your solar power plant by using direct and diffuse radiation data from Open-Meteo.com, calculating the position of the sun, and projecting the radiation on your solar panel. 
-
+It shows the estimated energy production for the next 16 days, with hourly values calculated for the preceding hour. As an example, if there are 150 Wh shown at 11:00 this means you can expect 150 Wh between 10:00 and 11:00 from your photovoltaic system.
-This app takes direct and diffuse radiation data from Open-Meteo.com, calculates the position
+The values starting with Σ show the cumulated energy since midnight of the first day.
-of the sun and projects the radiation on your solar panel.
+To use solXpect, you simply enter your latitude and longitude coordinates, as well as the azimuth and tilt of your solar panel. 
-It shows the estimated energy production for the next hours and up to 16 days.
+You also enter information about the peak power, efficiency, temperature coefficient, and area of your solar panel, as well as the maximum power and efficiency of your inverter.
-The hourly values are calculated for the preceding hour. So if there are 150 Wh shown at 11:00 this means you can expect 150 Wh between 10:00 and 11:00.
+Additionally, solXpect allows you to define shading on your solar panels by specifying the minimum elevation of the sun necessary for the sun to hit the solar panels, as well as the percentage of shading for elevations below this value.
+If you have multiple solar panels with the same latitude and longitude but pointing in different directions, you can define them as separate locations and use the 'show sum' feature to summarize their output.
+Overall, solXpect is a powerful tool for optimizing the use of your own energy and reduce your energy costs.

 ## Parameters
 
+#### Name
+Define a name for the location.
+If you have several modules pointing in different directions at the same location you can activate "showSum" mode in settings.
+In this case you should define your location names as 'myPV | part1', 'myPV | part2', etc. In 'show sum' mode the location is then shown as 'myPV' and '|' is taken as delimiter.
+
 #### Latitude [°] 
-Latitude specifies the north–south position of your solar power plant. It ranges from –90° at the south pole to 90° at the north pole.
+Enter the north-south position of your solar power plant, ranging from -90° at the south pole to 90° at the north pole.
 
 #### Longitude [°]
-Longitude specifies the east–west position of your solar power plant. The prime meridian defines 0° longitude. Positive longitudes are east of the prime meridian, negative ones are west.
+Enter the east-west position of your solar power plant, with 0° defined as the prime meridian. Positive longitudes are east of the prime meridian, negative ones are west.
 
 #### Azimuth [°]
-Azimuth is the horizontal direction of your solar power plant. 0° equals North, 90° equals East, 180° equals South, 270° equals West.
+Specify the horizontal direction of your solar power plant, with 0° corresponding to North, 90° to East, 180° to South, and 270° to West.
 
 #### Tilt [°]
-Tilt is the vertical direction of your solar power plant. 0° means it points up towards the the sky, 90° means it has a vertical orientation and points towards the horizon.
+Specify the vertical direction of your solar power plant, with 0° pointing upwards towards the sky and 90° being a vertical orientation pointing towards the horizon.
 
-#### Cells max power [W]
+#### Cells peak power [W]
-Maximum power your solar cells can deliver.
+Enter the maximum power your solar cells (total of all cells) can deliver. At the moment this value is only used if a value of 0 is specified for cells efficiency or cell area.
+In this case it is assumed that the cells peak power is given at an irradiance of 1000W/sqm.
 
 #### Cells efficiency  [%]
-Portion of energy in the form of sunlight that can be converted into electricity by the solar cell.
+Specify the portion of energy in the form of sunlight that can be converted into electricity by the solar cell.
 
 #### Temperature coefficient  [%/K]

+Enter the dependence of the cell power on temperature, usually in the range of -0.4%/K. Cell temperature is estimated from ambient temperature and total irradiance.
-Cell temperature is estimated from ambient temperature and total irradiance.
 
 #### Cell area [m<sup>2</sup>]
-Size of your solar panel.
+Enter the size of your solar panels (total of all cells).
 
 #### Diffuse radiation efficiency  [%]
-Efficiency of your solar power plant for diffuse radiation. When pointing up it should be around 100%, when pointing to the horizon it may be around 50%. 
+Specify the efficiency of your solar power plant for diffuse radiation. When pointing up, it should be around 100%, but when pointing towards the horizon, it may be 50% or less, depending on the environment.
-Also depends on reflections etc.
+You probably need to optimize this parameter.
+
+#### Albedo  [0..1]
+Specify the average albedo for your environment to take reflections into account. The value ranges from 0 (all radiation is absorbed) to 1 (all radiation is reflected).
+Examples: Fresh snow: 0.8, green gras: 0.25, asphalt: 0.1
+You probably need to optimize this parameter.
+
+#### Inverter efficiency  [%]
+Enter the efficiency of your inverter.
 
 #### Inverter power  [W]
-Maximum power of your inverter. If it is lower than the maximum power of your panels the output power of your system will be limited by this parameter.
+Specify the maximum power of your inverter. If it is lower than the maximum power of your panels, the output power of your system will be limited by this parameter.
 
-#### Inverter efficiency  [%] 
+#### Central inverter
-Efficiency of your inverter.
+Select this checkbox to apply the inverter limit to the entire system. When in 'show sum' mode, the power limits of all inverters with this checkbox enabled will be aggregated and used as the system-wide power limit.
 
 #### Shading
 In this section you can define the shading on your solar panels.
 For each azimuth angle range, you can specify the minimum elevation of the sun that is necessary for the sun to hit the solar panels.
 For elevations below this value you can set the percentage of shading. For example, a building will reduce radiation by 100%, a tree maybe only by 60%.
+You can use the sun icon button in the main window to get information about the current azimuth and elevation of the sun to determine at what elevation the sun gets above buildings or trees.

+Die Android-App solXpect prognostiziert den Ertrag Ihrer Photovoltaik-Anlage. Sie lädt direkte und diffuse Strahlungsdaten von Open-Meteo.com, berechnet die Position der Sonne und projiziert die Strahlung auf Ihr Solarpanel.
-der Sonne und projiziert die Strahlung auf Ihr Solarpanel.
+Anschließend wird die geschätzte Energieproduktion für die nächsten Stunden (bis zu 16 Tage) dargestellt, wobei stündliche Werte für die vorangegangene Stunde gelten. Wenn zum Beispiel um 11:00 Uhr 150 Wh angezeigt werden, bedeutet dies, dass Sie zwischen 10:00 und 11:00 Uhr 150 Wh erwarten können.
-Es zeigt die geschätzte Energieproduktion für die nächsten Stunden und bis zu 16 Tage an.
+Die mit &#8721 beginnenden Werte zeigen die kumulierte Energie seit Mitternacht des ersten Tages.
-Die Stundenwerte werden für die vorangegangene Stunde berechnet.
+Um solXpect zu verwenden, geben Sie einfach Ihre Breiten- und Längenkoordinaten sowie den Azimut und die Neigung Ihres Solarpanels ein.
-Wenn also um 11:00 Uhr 150 Wh angezeigt werden, bedeutet dies, dass Sie zwischen 10:00 und 11:00 Uhr mit 150 Wh rechnen können.
+Sie geben auch Informationen über die Spitzenleistung, Effizienz, Temperaturkoeffizienten und Fläche Ihres Solarpanels sowie die maximale Leistung und Effizienz Ihres Wechselrichters an.
+solXpect ermöglicht es Ihnen auch, Verschattungen auf Ihren Solarzellen zu definieren, indem Sie die minimale Sonnenhöhe angeben, die erforderlich ist, damit die Sonne auf die Solarzellen trifft, sowie den prozentualen Schatten für Höhen unter diesem Wert.
 
 <h2>Parameter</h2>
 
+<h3>Name</h3>
+Definieren Sie einen Namen für den Standort.
+Wenn Sie mehrere Solarpaneele mit denselben Breiten- und Längenkoordinaten, aber in unterschiedliche Richtungen ausgerichtet haben, können Sie sie als separate Standorte definieren und die Funktion "Summe anzeigen" verwenden, um ihre Leistung zusammenzufassen.
+In diesem Fall sollten Sie Ihre Standortnamen als "myPV | part1", "myPV | part2" usw. definieren. Im "Summe anzeigen"-Modus wird der Standort dann als "myPV" angezeigt und "|" wird in diesem Fall als Trennzeichen verwendet.
+
 <h3>Breitengrad [°]</h3>
-Der Breitengrad gibt die Nord-Süd-Position Ihres Solarkraftwerks an. Er reicht von –90° am Südpol bis 90° am Nordpol.
+Geben Sie die Nord-Süd-Position Ihrer Solaranlage an, die von -90° am Südpol bis 90° am Nordpol reicht.

 <h2>Overview</h2>
 
-This app takes direct and diffuse radiation data from Open-Meteo.com, calculates the position
+This app forecasts the output of your solar power plant by using direct and diffuse radiation data from Open-Meteo.com, calculating the position of the sun, and projecting the radiation on your solar panel.
-of the sun and projects the radiation on your solar panel.
+It shows the estimated energy production for the next 16 days, with hourly values calculated for the preceding hour. As an example, if there are 150 Wh shown at 11:00 this means you can expect 150 Wh between 10:00 and 11:00.
-It shows the estimated energy production for the next hours and up to 16 days.
+The values starting with &#8721 show the cumulated energy since midnight of the first day.
-The hourly values are calculated for the preceding hour.
+To use solXpect, you simply enter your latitude and longitude coordinates, as well as the azimuth and tilt of your solar panel.
-So if there are 150 Wh shown at 11:00 this means you can expect 150 Wh between 10:00 and 11:00.
+You also enter information about the peak power, efficiency, temperature coefficient, and area of your solar panel, as well as the maximum power and efficiency of your inverter.
+Additionally, solXpect allows you to define shading on your solar panels by specifying the minimum elevation of the sun necessary for the sun to hit the solar panels, as well as the percentage of shading for elevations below this value.
 
 <h2>Parameters</h2>
 
+<h3>Name</h3>
+Define a name for the location.
+If you have multiple solar panels with the same latitude and longitude but pointing in different directions, you can define them as separate locations and use the 'show sum' feature to summarize their output.
+In this case you should define your location names as 'myPV | part1', 'myPV | part2', etc. In 'show sum' mode the location is then shown as 'myPV' and '|' is taken as delimiter in this case.

-<h3>Cells max power [W]</h3>
+<h3>Cells peak power [W]</h3>
-Maximum power your solar cells can deliver.
+Enter the maximum power your solar cells (total of all cells) can deliver. At the moment this value is only used if a value of 0 is specified for cells efficiency or cell area.
+In this case it is assumed that the cells peak power is given at an irradiance of 1000W/sqm.
 
 <h3>Cells efficiency  [%]</h3>
-Portion of energy in the form of sunlight that can be converted into electricity by the solar cell.
+Specify the portion of energy in the form of sunlight that can be converted into electricity by the solar cell.

+Specify the efficiency of your solar power plant for diffuse radiation. When pointing up, it should be around 100%, but when pointing towards the horizon, it may be 50% or less, depending on the environment.
-Also depends on reflections etc.
+You probably need to optimize this parameter.
 
-<h3>Inverter power  [W]</h3>
+<h3>Albedo  [0..1]</h3>
-Maximum power of your inverter. If it is lower than the maximum power of your panels the output power of your system will be limited by this parameter.
+Specify the average albedo for your environment to take reflections into account. The value ranges from 0 (all radiation is absorbed) to 1 (all radiation is reflected).
+Examples: Fresh snow: 0.8, green gras: 0.25, asphalt: 0.1
+You probably need to optimize this parameter.
 
 <h3>Inverter efficiency  [%]</h3>
-Efficiency of your inverter.
+Enter the efficiency of your inverter.
+
+<h3>Inverter power  [W]</h3>
+Specify the maximum power of your inverter. If it is lower than the maximum power of your panels, the output power of your system will be limited by this parameter.
+
+<h3>Central Inverter</h3>
+Select this checkbox to apply the inverter limit to the entire system. When in 'show sum' mode, the power limits of all inverters with this checkbox enabled will be aggregated and used as the system-wide power limit.
 
 <h3>Shading</h3>
 In this section you can define the shading on your solar panels.
 For each azimuth angle range, you can specify the minimum elevation of the sun that is necessary for the sun to hit the solar panels.
 For elevations below this value you can set the percentage of shading. For example, a building will reduce radiation by 100%, a tree maybe only by 60%.
+You can use the sun icon button in the main window to get information about the current azimuth and elevation of the sun to determine at what elevation the sun gets above buildings or trees.

+<h2>Introduzione</h2>
+
+Questa app fa previsioni sulla produzione del tuo impianto fotovoltaico usando i dati di radiazione luminosa diretta e indiretta prodotti da Open-Meteo.com, calcolando la posizione del sole e proiettando la radiazione sul tuo pannello solare.
+Viene mostrata la stima di produzione del tuo impianto fotovoltaico per i prossimi 16 giorni, con valori orari calcolati per l’ora precedente. Ad esempio: se alle 11:00 viene mostrato il dato 150 Wh significa che devi aspettarti 150 Wh tra le 10:00 e le 11:00.
+I valori con il simbolo &#8721 si riferiscono all’energia accumulata dalla mezzanotte del primo giorno.
+Per usare solXpect devi conoscere alcuni parametri del tuo impianto: la latitudine, la longitudine, l’azimuth (orientamento misurato in gradi rispetto alla direzione del nord), l’inclinazione, la potenza di picco e la potenza massima dell’inverter.
+Per migliorare la stima puoi anche personalizzare altri dati ad esempio l’efficienza di conversione dell’inverter, l’efficienza dei pannelli, il coefficiente di temperatura e l’area dell’impianto.
+Infine solXpect gestisce anche gli eventuali ombreggiamenti del tuo impianto, infatti è possibile specificare l’elevazione minima del sole necessaria per illuminare i pannelli e la percentuale di ombreggiamento per le elevazioni minori di questo valore.
+
+<h2>Parametri</h2>
+
+<h3>Nome</h3>
+Scegli un nome per l’impianto.
+Se hai pannelli dello stesso impianto con direzione, inclinazione o ombreggiamento diversi puoi inserirli come impianti diversi e poi usare la funzione 'Mostra totale' per mostrare la produzione complessiva.
+In questo caso devi scegliere i nomi degli impianti come "mioFV | sezione 1", "mioFV | sezione 2", ... 'Mostra totale' utilizzerà "mioFV" come nome dell’impianto in quanto il carattere '|' viene considerato come separatore tra le diverse parti.
+
+<h3>Latitudine [°]</h3>
+Indica la coordinata nord-sud del tuo impianto, può variare tra i valori -90° (polo sud) e 90° (polo nord).
+
+<h3>Longitudine [°]</h3>
+Indica La coordinata est-ovest del tuo impianto, 0° è il meridiano di Greenwich, valori positivi indicato posizioni a est di tale meridiano, negativi l’ovest.
+
+<h3>Azimuth [°]</h3>
+Indica come è orientato sul piano orizzontale il tuo impianto, 0° indicano il Nord, 90° l’Est, 180° il Sud e 270° l’Ovest.
+
+<h3>Inclinazione [°]</h3>
+Indica l’inclinazione sul piano verticale del tuo impianto, se l’impianto punta direttamente il cielo sarà 0°, invece sarà 90° per pannelli verticali.
+
+<h3>Potenza di picco [W]</h3>
+Indica la massima potenza del tuo impianto, spesso nel progetto dell’impianto è indicata con l’unità di misura Wp. Attualmente questo valore viene utilizzato solo se è il valore dell’efficienza delle celle o dell’area è 0.
+In questo caso si suppone che che le il valore di picco delle celle si raggiunga con un’irradianza di 1000W/mq.
+
+<h3>Efficienza dei pannelli [%]</h3>
+Indica la porzione di energia luminosa che viene convertita in elettricità dai pannelli.
+
+<h3>Coefficiente di temperatura [%/K]</h3>
+Indica la dipendenza della potenza dei pannelli dalla temperatura, tipicamente è un valore attorno a -0.4%/K. La temperatura dei pannelli viene stimata in base alla temperatura ambientale e all’irradianza totale.
+
+<h3>Area dei pannelli [m<sup>2</sup>]</h3>
+Indica l’area totale del tuo impianto.
+
+<h3>Efficienza della radiazione diffusa [%]</h3>
+Indica la capacità di catturare la radiazione diffusa. Per impianti poco inclinati si avvicina al 100%, per impianti molto inclinati potrebbe essere del 50% o meno, in base all’ambiente circostante.
+
+<h3>Albedo [0..1]</h3>
+Indica la capacità dell’ambiente circostante il tuo impianto di riflettere la luce solare. I valori variano da 0 (tutta la luce viene assorbita), a 1 (tutta la radiazione viene riflessa).
+Esempi: neve fresca: 0,8 ; erba verde: 0,25 ; asfalto: 0,1 .
+
+<h3>Efficienza dell’inverter [%]</h3>
+Indica l’efficienza di conversione dell’inverter.
+
+<h3>Potenza dell’inverter [W]</h3>
+Indica la potenza massima gestita dall’inverter. Se è minore della potenza massima dei pannelli, la produzione dell’impianto verrà limitata da questo parametro.
+
+<h3>Invertitore centrale</h3>
+Seleziona questa casella di controllo per applicare il limite dell'invertitore all'intero sistema. Quando si è in modalità "mostra totale", i limiti di potenza di tutti gli invertitori con questa casella di controllo abilitata verranno aggregati e utilizzati come limite di potenza dell'intero sistema.
+
+<h3>Ombreggiamenti</h3>
+In questa sezione puoi definire gli ombreggiamenti dei pannelli.
+Per ogni intervallo di azimuth è possibile specificare a quale altezza minima il sole illumina i pannelli.
+Per altezze minori di questo valore è possibile impostare la percentuale di ombreggiamento. Ad esempio un edificio riduce la radiazione solare del 100%, un albero circa del 60%.
+Per impostare questi valori è possibile utilizzare i dati correnti di azimuth e altezza del sole che vengono mostrati premendo l’icona con il simbolo del sole che si trova nella schermata principale.
