8. Scope of SPV AND SOLAR ENERGY
Conclusion
3. •Cells are made up of silicon.
•SPV connected assembly of solar cells.
•SPV module is used to convert sun light
into electrical energy.
•Output of each cell is 0.5 - 0.6 volt DC.
•Output Current depends on Area of the
cell and the amount of Light falling.
•Higher voltages and current are obtained by
connecting these cells in series or
parallel according to the requiiement.
4. •They are made up of Silicon which is a
semi conducting material.
•These material absorb the sunlight ,
thereby knocking out loose electrons
from their atoms, allowing the electrons
to flow through the material to produce
electricity.
•This process of converting light
(photons) to electricity (voltage) is called
the Photovoltaic (PV) Effect
•This energy is stored in batteries and can
be used in night hours.
6. Manufacturig process of SPV Modules
•Tabbing Of Cells
• Row Making
•Stringing
•Lay- Up
•Lamination
•Curing
•Trimming
•Channeling
7. 1. TabbingofCells
Normally 30 or 36 cells are connected to deliver enough voltage to charge
a 12 volt battery. These series connected cells are called a string, and the
process is called stringing. Tabbing is the process in which the cells are
connected in series.
Flat copper conductors about 2mm wide (suitable for most panels) with pre-
soldered surfaces are used to connect front bus bars of one cell to the
corresponding rear bus bars of the next cell to achieve a series
connection. Tabbing ribbons are especially made for this purpose.
Tabbing
8. 2. Row making
A row of cells is made by connecting positive surfaces of one cell to the negative
surface of another cell.
9. In a larger PV array, individual PV modules are
connected in both series and parallel. A
series-connected set of solar cells or modules
is called a "string“.
10. 3.1 Stringing checking
This String is checked visually for any kind of faults.
•Reverse string Dry point
•Dry Point
•Dry soldering
•Loose connection
11. 3.2 Lay-up
• In this process,
solar cell are put in
cells are put between
various layers for
lamination and curing
process.
•Laminating materials
are TOP Glass EVA
sheets
Hclght &Angy adjustment support
12. 4. Lamination
•Solar cells are laminated
between back sheet and high
transitivity toughened glass.
•V EVA is used to provide
environmental protection.
•The designed lay up is
sand-witched between these
layers.
•This process takes place
at1l0"C for l l minutes.
13. 5).Curing
• This process comes
after the lamination to
attain the full strength of
laminating material.
• The module is placed
into 120°C temperature
for 20 minutes.
16. 7).Channeling
•Modules are channelled from
all the four sides. Anodized
aluminium frames are used for
channelling.
• Channels prevent any damage
to the module.
•A terminal box is also fitted for
external connections.

18. FEATURES :-
•Can be designed for variety of
applications and operational
requirements.
• Have no moving parts.
•Expandable.
•Transportable.
•The fuel (sunlight) is free.
•No noise pollution or any other type
of pollution.
•Requires minimum maintenance.
•Have long service lifetimes (upto 20
years).
22. As we all know that INDIA is facing huge shortage
of Coal supply since past 1 week. In this scenario,
India and It’s people are going to be highly
dependent on Solar Energy
