# pvCaster

pvCaster forecasts the output of your solar power plant

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.

## Parameters

#### 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.

#### 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.

#### Azimuth [°]
Azimuth is the horizontal direction of your solar power plant. 0° equals North, 90° equals East, 180° equals South, 270° equals 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.

#### Cells max power [W]
Maximum power your solar cells can deliver.

#### Cells efficiency  [%]
Portion of energy in the form of sunlight that can be converted into electricity by the solar cell.

#### Cell area [m\u00b2]
Size of the active area your solar panel.

#### 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%. 
Also depends on reflections etc.

#### 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.

#### Inverter efficiency  [%] 
Efficiency of your inverter.
