<h2>Overview</h2>
|
||
|
||
This app takes direct and diffuse radiation data from Open-Meteo.com, calculates the position
|
||
of the sun and projects the radiation on your solar panel.
|
||
It shows the estimated energy production for the next hours and up to 16 days.
|
||
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.
|
||
|
||
<h2>Parameters</h2>
|
||
|
||
<h3>Latitude [°]</h3>
|
||
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.
|
||
|
||
<h3>Longitude [°]</h3>
|
||
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.
|
||
|
||
<h3>Azimuth [°]</h3>
|
||
Azimuth is the horizontal direction of your solar power plant. 0° equals North, 90° equals East, 180° equals South, 270° equals West.
|
||
|
||
<h3>Tilt [°]</h3>
|
||
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.
|
||
|
||
<h3>Cells max power [W]</h3>
|
||
Maximum power your solar cells can deliver.
|
||
|
||
<h3>Cells efficiency [%]</h3>
|
||
Portion of energy in the form of sunlight that can be converted into electricity by the solar cell.
|
||
|
||
<h3>Temperature coefficient [%/K]</h3>
|
||
Dependence of the cell power on temperature (usually in the range of -0.4%/K).
|
||
|
||
<h3>Cell area [m<sup>2</sup>]</h3>
|
||
Size of your solar panel.
|
||
|
||
<h3>Diffuse radiation efficiency [%]</h3>
|
||
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%.
|
||
Also depends on reflections etc.
|
||
|
||
<h3>Inverter power [W]</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.
|
||
|
||
<h3>Inverter efficiency [%]</h3>
|
||
Efficiency of your inverter.
|
||
|
||
<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%.
