50 kWp Grid Interactive Solar PV Rooftop System

A. System Definition

Size:
50 kWp Total DC Capacity.
200 nos. 250-watt panels (Webel Solar)

Energy Production:

Site Location: 28º 7
Tilt Angle: 28º South
Monthly averaged radiation: 5.01 kW-hours/m2/day

Net Energy Generation Estimate: 71,000 kWhr/year*

* Assumptions:

Solar radiation data source: NASA/ PVSyst
Seasonal variation in daily/monthly/annual solar radiation will affect the energy
generation of the plant.
AC output has been arrived after considering de-rating factors such as dust, series-
parallel mismatch, cable drop, insolation, inverter efficiency, temperature.

System Description:

The main feature of the proposed system is seamless grid interactive solar energy supply to
the designated lighting load. The system always gives priority to the energy provided by the
Solar module. In combination with a controllable second source (grid supply in our case),
the energy supply remains reliable and available 24 hours a day, all year round. We shall
use the 3-Phase Solar Inverters of Solivia Delta based on its availability.
