DC & AC Electrical Services

To have a functional solar PV system, you need to wire the panels together to create an electrical circuit through which current will flow, and you also need to wire the panels to the inverter that will convert the DC power produced by the panels to AC power.

​

It needs to be understood how different stringing configurations impact the voltage, current, and power of a solar array. As a key factor in the installation process we offer the following:

• AJB, MJB fixing as per the layout.

• Cabling – Arrays, Interconnection between Arrays and AJBs and AJBs & MJBs.

• Cable routing through structure and trenches & Cable dressing.

• DC Testing.

• Voc & Isc at Array, AJB, MJB and Inverter level

• Polarity test.

• Cable continuity.

• Installation of the junction boxes and SMUs.

• Connection Arrays to AJBs, AJBs to Combiner box, CB to Ir.

• Switch yard works.

• Control room Cabling works, Cable trenches & Cable dressing.

• Plant Grid connectivity works.

• GIS Sub Station works.

• AC cabling and termination from inverter to Inverter duty transformer.

• HT terminations and HT cable joint works.

• HT cable laying from IDT to HT panel and field HT panel to MCR room and terminations.

• Transformer installations and oil filtration test.
