2. How to use SOLAR POWER for your Commercial Use?

Primarily a Solar Power system works as under

The Solar Module generates electricity when the sun shine falls

on it and through a Charge Controller it is charged into the

Battery and later using an Inverter it is connected to the load. It

can also directly feed the load without Battery using the Inverter.

Therefore there are two types of system which you can use :

1. Systems with storage or battery back up

2. Systems without battery and exporting power to grid

when not consumed through net metering.

The selection of the type of system depends on your needs.

If you are living in a power cut area and your primary need to invest on solar power system is

to have power during power cut times then you must go for SOLAR SYSTEMS with Battery

back up. In these Battery back up systems – you can also save EB bills during non power cut

times and can also use solar power during power cut times. The maximum size of OFF GRID

solar solutions can be 10 KW and if your need is more than 10 KW , you may add multiple

systems of 10 KW .

If you are living in a area where there is no Power cut at all and your primary interest to use

solar power is for saving of electricity Bill , then you can have SOLAR SYSTEM without battery.

However , the Net Metering process is unpredictable and you will not be able to use or upload

solar power in case of EB failure.

3. DIFFERENT TYPES OF SOLAR SYSTEMS FOR HOME.

SOLAR SYSTEMS WITH BATTERY BACK UP

This type of system comes with battery back-up. The Solar electricity generated, is used for

charging the battery first and once the battery is charged it is given to the load directly with

any additional requirement is taken from the normal electricity supply . There are two

choices of selection available and they are

OPTION 1:

� SOLAR - EB - BATTERY - means order of preference to the load -

First priority is Solar Power, when Solar Power is not available EB power is used and when

both not available Battery power will be used. These are ideal for buildings which have

Power Cut.

OPTION 2

� SOLAR - BATTERY - EB - means order of preference to the load -

The first priority is Solar Power, next is Battery and last will be EB Power. These are

suitable for buildings which has No Power Cut. If you are not going to be in the house in the

day time to use solar energy when generated , go for this mode. When you return back the

battery will give you the power which was saved during day time. If you use this mode – you

may not have battery storage when there is a power cut.

SOLAR SYSTEM WITHOUT BATTERY

These systems are meant for installations on your Roof top. These type of systems do not

have any battery back-up. The Solar power generation, through the inverter , is directly

given to the load in the building. When there is no consumption the solar power can be

exported to the Grid. Now we have NET METERING available and therefore every unit

exported to the Grid can save your electricity bill. These are very common for those who are

installing Roof Top Power Plant to meet the SPO obligation and for those who are primarily

installing Solar Power Plant mainly to save on electricity cost . These system generally will

have EB power source and/or diesel genset.

TIN : 33631360946



The main criteria to remember for installation this system is

� There is no storage available for the electricity generated from the solar power.

� There will no output from the inverter, if even Solar Energy is generated,

without availability of EB power or genset power.

� If the load is less than the generation of the solar power then the excess solar power

will be given back to the grid and the customer need to install NET METER.

These aspects are a must for a customer to know before choosing the system. Not many

suppliers reveal this crucial aspects of the design.

NET METERING ; The concept of NET metering allows a customer to export electricity to

Grid and claim for the units exported in their EB bills. There are separate two directional

meters available to achieve this purpose. When EB power is used the meter runs in one

direction and when Electricity is exported to Grid it runs in the opposite direction. Separate

approval must be taken from the local TANGEDCO office for this net metering installations .

Net metering is not available in Battery back up systems.

4. How to calculate System Sizing?

You can note down your EB METER Number and go into

http://tneb.tnebnet.org/newlt/menu3.html . On your entering the details of your

meter no , you will get complete details of your Tariff Code , Rate , consumption etc

etc…

From the number of units consumed a month , you can estimate your capacity of solar

system. Every 1 KW of solar system will generate a useful energy of 4 Units a day and

approximately about 330 days a year in TN.

Based on this thumb rule , you can decide what capacity of solar system you want to

have. Let us say your total monthly usage is 10000 Units. Assume you work for 23

days a month and there is no consumption after office hours. Then you daily

consumption is about 435 units. In case if you want to install 25% of this need to be

met from solar – then you need a solar plant which can generate about 110 units a

day. Then you go for a solar system of about 25 KW , which can generate about 100

units a day. On the days when you do not have usage and if there is no NET METERING

available then you must switch off the solar plant . Also you can calculate the required

solar power plant from the roof area available. For example a 10 KW solar plant

requires about 1000 sq ft of area.

5. Site Feasibility

A shadow free space (area based on system capacity) should be available in the roof top

facing South direction (North direction can be selected if South direction is not feasible).

The roof can be Flat / Angular facing south. It needs to have the approach to clean

periodically. Inverters and Batteries ( if applicable) will be kept nearer to the Main

Distribution Box. The load of each block in the building should be calculated separately. The

weight of a solar module will be about 0.20 kg per watt. Size of each module is 985 mm x

1665 mm for a 250 W module.
