Topics We Learnt At REIL

Solar Photo Voltaic (SPV) Cell Production

Renewable Energy

Agro-Diary Products

Other Projects ( Fire alarm, Energy meter, CCTV )

12

Why Solar Energy?

It is Free.

It is Clean.

It is Infinitely renewable.

It can reduce our utility cost.

It increases our energy self reliance.

It is extremely reliable.

13

Solar Photo Voltaic (SPV)Modules

Connected assembly of solar

cells.

Output of 0.5 - 0.6 volt DC.

Output Current depends on Area

of the cell and the amount of

Light falling.

So efficiency is determined by the

area of a module.

14

How PV Cells Work?

Composed of ultra-thin layer of N type silicon on top of a

thicker layer of P type silicon.

Manufacturing Process ofSPV Modules

Processes during manufacturing of SPV modules :-

Part I Part II

1. Tabbing of Cells 1. Lamination

2. Row Making 2. Curing

3. Stringing 3. Trimming

4. Lay up 4. Testing

5. Terminal Box Fitting &

Soldering

17

Manufacturing Processin Detail

1. Tabbing of Cells Process of making terminals of a bare cell by soldering

copper strips to the bus bar.

18

Manufacturing Process in Detail(Contd..)

2. Row Making

A row of cells is made by connecting positive surfaces of one cell to the negative surface of another cell.

19

Manufacturing Process in Detail(Contd..)

3. Stringing The rows of SPV cells are connected in series to get

desired power rating.

20

Manufacturing Process in Detail(Contd..)

4. Lay-up

In this process, solar cells are put in between various layers for lamination and curing process.

Pros & Cons of PV Cells

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 othe type of pollution. Requires minimum maintenance. Have long service lifetimes (upto 20 years).

Advantages

23

Pros & Cons of PV Cells(Contd..)

High Cost. Large Surface Area. Doesn’t work at night. Not reliable unless kept in a very sunny climate.

Disadvantages

24

Conclusion

Provided me the knowledge about industrial management, technology involved, structure and functioning of the company

Gave me experience of working in a professional environment.

Given me an idea regarding how the theoretical things are put into application and the errors that are encountered during execution.
