Customer Scope
• The present DB may be renovate as per KSEB Inspectorate recommendations.
• Price includes 15 meter cables ( AC and DC ) other than will be charged
• The system price is for a normal flat roof. Any additional structure work as per
customer requirement will be charged extra
Project Description:-
SoftiBuy recommends a Solar Grid Synchronous system (without batteries) that maximizes on
bill reductions and saves on diesel consumption. Through this system the facility will be able to
make the most of “Net Metering” policy if applicable, where the customer can export extra
units back to the Grid and avail usable credits. This can be beneficial during Sundays and
vacations when consumption is minimal.
GRID-TIE SOLAR SYSTEM
• This is the best option where energy consumption during the daytime is large,
when the sun is out.
• Elimination of battery backup reduces initial costs and maintenance issues.
• For a location where net-metering is in force, this option is ideal as it would help
the building in reducing electricity bills
WORKING PRINCIPLE :-
• The solar modules when exposed to sunlight generate DC electricity.
• Solar Grid Tied Inverter performs the conversion of the variable DC output of the
PV modules into a clean sinusoidal AC power.
• This inverter needs a synchronizing power which will be either the Grid or DG
• The Solar Current will be given lead angle in synchronization process and it will
be forcefully injected into the bus bar
• The Loads will be supplied with Solar Power as a prime source of energy and Grid
and DG power will supply remaining part of requirement.
SYNCHRONIZATION :-
The inverter measures the grid (voltage, frequency, phasing) and uses this information
to synchronize the internal regulation. It means the inverter starts up with an open grid
contactor and with a grid independent frequency. Then the controller changes the internal
frequency, voltage and phasing so long as this is absolutely identical to the given values from
the grid. Now the electronics will close a soft start contactor to pre magnetize the internal
transformer. Few parts of a second later the main grid contactor will close and the inverter
will feed in. If the grid values are changed when the inverter feeds in the grid, monitoring will
detect it and the controller will adjust the internal regulation so that the inverter is
synchronized with the grid all the time.
PROTECTIONS :-
• DC Side modules will be given DC Dis-connector Switch which will protect the
System
• For all kinds of faults the Solar Inverter will react first and ISOLATE itself from the
system in Microseconds of time
ADVANTAGES:-
• Simple and Safe system which gives Direct Savings in Electricity Bill
• Efficient, fit and forget system with least losses
• 25 years of Guaranteed Generation with Payback Period of 4-7 years
• 1 kWp of Solar Power Plant Generates 3.9- 4.4 Units of Electricity per day
• Accelerated Depreciation on the Investment
LIMITATIONS :-
• No Back up will be given from the system, since solar power directly utilized
• When power goes off (Grid or DG) Inverter will isolate from the system, stop
feeding and Solar Power will go waste
• Normal meters will rotate in the same direction even when is exported to the
grid and feed power will be charged, so load analysis is critical without net
metering
