Simulated Solar Inverter

Configurable solar PV inverter with realistic generation patterns based on panel characteristics.

Configuration

{
  "Name": "sim-solar",
  "DeviceClass": "SimulatedSolarInverter",
  "AssetType": "Solar",
  "SimulatedSolarInverter": {
    "InstalledCapacityW": 10000.0,
    "RoofAngleDegrees": 30.0,
    "OrientationDegrees": 180.0,
    "Technology": "Monocrystalline"
  }
}

Configuration Options

Property	Description	Default
InstalledCapacityW	Installed capacity in watts	10,000 W (10 kW)
RoofAngleDegrees	Panel angle from horizontal (0°=flat, 90°=vertical)	30°
OrientationDegrees	Panel azimuth (0°=north, 90°=east, 180°=south, 270°=west)	180° (south)
Technology	Panel technology type	Monocrystalline
InitialExportRegisterWh	Initial export energy register	5,000,000 Wh (5 MWh)

Panel Technologies

Technology	Efficiency	Characteristics
Polycrystalline	15-17%	Lower cost, lower efficiency
Monocrystalline	18-22%	Standard choice, good efficiency
Heterojunction	21-24%	Premium, highest efficiency
ThinFilmAmorphous	10-12%	Better low-light performance

Angle & Orientation

Roof Angle

Optimal angle depends on latitude. For most of Europe/US:

Angle	Description
0°	Flat roof (suboptimal)
25-35°	Optimal for mid-latitudes
45°	Steeper roofs, good for winter
90°	Vertical (façade-mounted)

Orientation

Degrees	Direction	Output
0°	North	Minimal (northern hemisphere)
90°	East	Morning peak
180°	South	Maximum annual output
270°	West	Afternoon peak

Features

• Technology-based efficiency: Different panel types with realistic efficiency curves
• Angle optimization: Output affected by roof angle (optimal ~30-35°)
• Orientation effects: South-facing panels produce most energy in northern hemisphere
• Profile-based generation: Uses SimpleSolarProfile for time-of-day curves
• Cloud cover simulation: Random variance for realistic patterns

Custom Solar Profiles

Override the default SimpleSolarProfile by implementing ISolarProfileProvider:

public interface ISolarProfileProvider
{
    double GetSolarOutput(DateTime utcTime, double installedCapacityW);
}

Register your custom provider via DI:

services.AddSingleton<ISolarProfileProvider, MyCustomSolarProfile>();
