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.


B. System Components 1. Solar Panels The technology chosen specific to the project site is Polycrystalline PV modules manufactured by Webel Solar. The solar modules generate DC energy output. Note: Subject to availability at installation time, a different panel from a leading vendor may be selected without affecting system size and performance.

Make: Webel Solar Technology: Poly Crystalline PV Quantity: 200 Wattage: 250 W No. of Cells: 60 Nominal Voltage: 37.7 V DC Isc: 8.68 A DC Vmp: 30.5 V DC Imp: 8.2 A DC Dimensions: 1645X992X42 (mm)Limited Warrantee: 25 yrs Weight: 21 kg Operating Conditions: -40 to +90 C Maximum System Voltage: 1000 Vdc


2. Solar Inverter Solar array produces DC energy output. The DC energy, thus produced has to be utilized to maximum and supplied to the DC bus for inverting to AC voltage. Power Conditioning Unit does exactly this job using its MPPT control to extract maximum energy from solar array and provides 415Vac, 3-ph 50Hz to synchronize with local grid. Additionally, it has protection features such as, over current, short circuit, over temperature to name a few. It has user friendly LCD display for programming and view on line parameters. The typical specification is listed out below.

Make: Solivia Delta Energy (CS 44) Technology: MPPT Solar Inverter Quantity: 1 Nominal AC Power: 50 kW Maximum Output Power: 44.4 kW AC Voltage: 3Phase 415V, +/-10% Frequency: 50Hz Total Harmonic Distortion: <3% AC Over Voltage Protection: Yes Phase Shift (Cos Phi): 1 PV Entries: 3 Maximum DC Voltage: 880V MPPT Voltage Range: 450-800V Maximum DC Current: 105 A DC Voltage Ripple: <3% DC over voltage Protection: Yes Maximum Efficiency: 95.6% Ambient Temperature Range: 15-95% Degree of Protection: IP54

Grid Tied Central Solar Inverter


3. Mounting Structures

Panels shall be mounted on galvanized MS Steel frames on the roof surface. The structure is designed in such a manner that module can be replaced easily and in line with site requirements and it is easy to install and service in future. The frames will be supported by angle legs of suitable lengths to provide the pre-determined inclination. All fasteners, nut and bolts are made of Stainless steel - SS 304 5.4.6 PCC. The structures shall be pre engineered to meet special requirements of placing the modules on the corrugated rooftops. The legs of the structures made with GI angles are made of fixed and grouted in the PCC foundation columns made with 1:2:4 cement concrete.


4. Electrical Accessories

Cables will conform to IS 694 and shall be of 650 V/ 1.1 kV grade. Interconnections, array to junction boxes, junction boxes to DCDB, DCDB to PCU etc will be selected to keep voltage drop and losses to the minimum. The bright annealed 99.97% pure bare copper conductors offer low conductor resistance, result in lower heating thereby increasing cable life and efficiency.. These wires are insulated with a special grade PVC compound formulated and manufactured in-house. Working voltage: up to 1100 V Temperature range: -15 deg C to +70 deg C Sizes: Suitable sizes Color codes: Red, Yellow, Black, Blue, Green

5. Battery

The Solar PV Grid Interactive system obviates the need of any battery.

6. Energy Meter

The Inverter shall have a built-in meter that tracks energy production and displays it on a small LED screen. The display can be used to determine real-time production, daily production, and yearly production. For more sophisticated analysis and visual data management, Solar Access modules can be included.
