Decentralized photovoltaic power plant solution
What is decentralised energy?
Decentralised energy, is characterised by generation of power nearer to the demand centers, focusing mainly on meeting local energy needs. A decentralized power system can function either in the presence of grid, where it can feed the surplus power generated to the grid, or as an independent/stand-alone isolated system exclusively meeting the local demands of remote locations. Further, decentralized power is also classified on the basis of type of energy resources used—non-renewable and renewable
Benefits of decentralized solution
⦁ Generated power where it is needed
⦁ Lowers transmission losses and carbon emissions as well as peak hour demand.
⦁ Modularity of string inverters is better for systems with different array angles and/or orientations.
⦁ Fewer arrays are impacted with one inverter failure.
⦁ Lower balance of systems costs.
⦁ Lower ongoing maintenance costs (e.g., no fans or air filters).
⦁ Simpler design and modularity; ideal for limited inverter pad spaces.
Decentralized photovoltaic power plant solution includes:
⦁ DC wiring box for String
⦁ String inverter with or without integrated DC wiring box
⦁ AC combiner box with MCB´s
⦁ Low Voltage (LV) Box
⦁ LV/MV transformer
⦁ MV switchgear
⦁ Solar monitoring system
In a ground mounted photovoltaic power plant system, multiple string inverters are connected to an AC combiner box. and multiple AC combiner boxes are connected to LV Box, LV/MV transformer and switchgear before the connection to the medium voltage grid.
Using three phase string inverters, customers can benefit from faster installation and minimal system downtime due to short replacement lead time and ease of servicing. Also the optimized design approach around standard building blocks can allow customer scale project sizes up and down with ease.
