2^nd Portion of the Biggest Rooftop Solar Power Plant

Here we will discuss only the second part of this rooftop solar PV plant.

Solar PV Module:

There are a total of 5408 solar PV modules installed in this part of the solar power plant. Each Solar PV module is monocrystalline and manufactured by Panasonic. Each solar PV module is rated as 325W in standard test conditions. There are 13 PV modules in series in each string. For some inverters, there is a total of 24 input of DC strings, and for some inverters, there are 25 inputs of DC strings.

Specifications of these solar PV modules are already discussed in the first portion of this Power plant. To read the specifications of Solar PV Modules click here.

Solar PV inverter:

There are a total of 17 solar PV inverters in this portion of the largest rooftop solar power plant of UAE. Each inverter is rated as 100KVA. These solar PV inverters are connected in parallel. All the solar inverters are installed on the rooftop. Further specifications are discussed in the first part of this article.

DC String Cables:

DC string cable used in this power plant is 6mm² copper cable with double protection. This DC cable is suitable for outdoor installations.

AC Output Cables:

There are two different sized AC cables are used in this solar power plant. From solar PV inverter to the AC combiner box Ac cable size is 70mm² and from AC combiner box to the meter cabinet AC cable size is 150mm².

AC Combiner Box:

There are three AC combiner boxes used for this portion of the largest rooftop solar power plant of UAE because there are three different points of connection for this solar power plant. All the AC combiner boxes have interface protection relays.

Breakers and Relays:

All the breakers and relays used in this biggest rooftop solar power plant are manufactured by ABB and approved by DEWA.

Mounting Structure:

There is no specific mounting structure is used in this largest rooftop solar power plant of UAE. Only clamps are used which are connected with the roof and holds the solar PV modules. There are four clamps under every solar PV module.

Cable Trays:

Different sized cable trays are used in this solar plant. There are two different sized DC cable trays are used in this plant which are 200mm and 400mm. And AC cable trays are 400mm and 600mm wide.

Weather Monitoring System:

The weather monitoring system is comprised of different components which include irradiance sensor, pyranometer, air sensor, and temperature sensor. The irradiance sensor is made by meteo control Energy and Weather Services. Whereas other components are made by Lufft. All these components of the weather monitoring systems are connected to the meteo control data logger, which is connected to the internet.

Online Monitoring System:

Like all other solar power plants, this largest solar power plant also has an online monitoring system. The online monitoring system used in this solar power plant is made by meteo control. Using meteo control online monitoring portal you can access this power plant from all over the world. Using this online monitoring system we can access that power plant and monitor its performance. You can monitor even at a string level using this monitoring portal.
