5.0.0. OVERVIEW OF SOLAR PV PLANT

The 1x50 M Wp solar photovoltaic pow er plant for M / S NTPC at M andsaur District in M adhya
Pradesh, comprises of an array of solar PV modules that produce DC output. Pow er
Conditioning Units (inverters) are deployed to convert the electricity from DC to AC. The
inverter output is further stepped by outdoor transformers. Power generated is exported to
transmission grid. The various electrical panels such as inverters, circuit breakers (VCB),
AC/ DC distribution boards, UPS panels etc. are housed in 11 nos. rooms. Among these, 10
nos. are inverter rooms of PEB type for w hich foundation up to plinth level is of RCC structure
and above plinth, PEB steel structures/ sheets shall be used for construction. Generation from
each PEB inverter room is 5M Wp. Thus, all 10 nos. inverter rooms collectively generate
45M Wp. In addition to the inverter rooms, t he securit y room (~4 sqm) is also of PEB type.

The 10 nos. PEB inverter rooms are located at distribut ed locations w ithin the pow er plant.
AC outputs from all these rooms are combined at CM CS room. Security room is located near
the entrance gate.
