Renewable Energy Power Plants (Solar/Wind)
Get the string design wrong on a solar site and part of the array falls into shade in the afternoon, cutting the string's output.
The electrical infrastructure that sets output
On the solar side, the electrical infrastructure runs from DC cabling through inverter selection to the AC combiner panel. On the wind side, what matters is lossless transmission of power carried at medium voltage from the turbine output to the switchyard.
Solar plant electrical infrastructure
String design follows the shading profile of the panel arrays and the inverter's MPPT input range; getting the string length wrong causes a production loss.
Wind plant electrical infrastructure
Turbine output is usually at medium voltage, which reduces losses inside the plant; the collection line cross-section is sized against voltage drop.
What's Included
- Solar site survey and shading simulation
- String design and DC cabling
- Inverter selection and AC combiner panel
- MV collection line design for wind plants
- Switchyard and grid connection infrastructure
- Insulation and earthing tests
- String-level current-voltage measurement
In a phased commissioning model, actual production data from the first phase feeds directly into the investment decision for the second.
