B. Technical:

1. Grid Tie System:-

An electric grid can be considered as a large sink of energy wherein energy generated by

Solar PV can be supplied or taken from the grid as & when required. The useful roof area

available at Proposed reconstruction of Oshiwara Maternity Home on plot bearing CTS

No. 486(pt) of Oshiwara village in K/West ward. for Solar PV system is approx 275

Sq.mtr, and the estimated capacity of the PV system to be installed is 20 KWp. The power

produced by 20 KWp PV systems is used by the local loads connected to LTMCC panel at

Oshiwara Maternity Home.

A grid connected Solar PV system typically consists of following components:

i. Solar PV array. ii. DC cabling.

iii. Grid connected Inverter. iv. AC cabling. v. AC interconnection to the existing LT panel.

vi. Solar optimizers.

2. Capacity estimation of solar PV system:-

Solar Cell is a semiconductor device that converts sun light energy into Electrical energy

directly without going through any intermediate energy conversion steps. Single solar cell

can generate very less power (Voltage and Current) like 2-3watts depending on the area of

the cell and typical DC voltage is 0.5V. In order to produce high power, the number of cells

are connected together to make a Solar PV module and several PV modules are connected

together to make PV array and PV array connected together to make a Solar PV Plant. The

PV modules are available from small wattage rating of 10Wp to 400Wp. The PV module is

characterized by main parameters useful for practical application such as maximum

current(Im), maximum voltage(Vm) and maximum power(Pm).The PV modules are

connected in series to increase the voltage. The single row of series connected PV module is

referred as PV module string. Strings are connected in parallel. Such a series and parallel

combination is referred as Solar PV array. The useful roof area available at Oshiwara

Maternity Home for Solar PV system is about 275 Sq.mtr. The typical size of the module is

approx 2m x 1m i.e.2m2 and wattage capacity is 320/325 watt per module is considered for

calculation. The output of power generated is affected when light is not falling perpendicular

to module. The modules are installed south facing at an inclination angle equal to latitude of

the location so that most of the time sunlight is close to the perpendicular. However, for the

77

estimation and capacity calculation purpose, total 63 P.V. modules can be easily

accommodate in the available area with considering sufficient area between the rows of the

Solar modules, sufficient area along the sides and area for DC-AC cabling work.

Energy Estimation calculation:-

Number of modules on the roof= 63

WATTAGE OF EACH MODULE=320WP

Total Wattage of the Plant=320 x63= 20,160Wp =( Approx 20 KWp)

3. Solar PV Module:-

Module Interconnection cable shall be provided. Photoelectric conversion efficiency of SPV

Module shall be greater than 16.5 %. Module shall have hot butyl rubber edge sealant for

module protection. The module shall be UL and CE approval. The module frame is made of

8.7 Estimation of Energy Production

The average daily solar radiation of the plane is 5KWh/m2/day.

The average daily solar radiation of 5KWh/m2/day = solar power density of

1KW/m2 for 5 hrs per day.

Monthly energy production= Plant capacity x Average sun hrs. x 31

= 20 x 5 x 31

=3100 KWh.

Considering plant performance ratio

of 70%, Monthly energy production=

0.7x 3100 =2200 KWh. Yearly

energy production=2200x12

= 26400 Kwh/year. 26,400 Kwh/year.

Production loss in monsoon /Cloudy weather conditions= 26,400Kwh x 0.2=

5000 Kwh/year. Guaranteed Yearly energy production = 26,400 Kwh - 5000

Kwh = 21,400 Kwh.
