This document discusses developing a 1 MW solar power plant in India. Key points: - A 1 MW plant can generate Rs. 1.2 lakhs per day by selling electricity at Rs. 15/unit and additional income from carbon credits of Rs. 24 lakhs annually. The government offers higher tariffs and low-interest loans for solar projects. - The solution proposes setting up a solar tracker manufacturing plant in India with a Rs. 25 lakhs investment and combining solar thermal and PV technologies to increase efficiency above 50% with a Rs. 1 crore investment. - Funding details are provided for a 1 MW reference solar power plant with an estimated total cost of Rs. 26.

1. Developing solar power plant

2. purpose
‡ A 1 MW solar power plant generates 8000 KWH unit of electricity per
day which can be sold at Rs 15 / unit giving an income of Rs 1.20
lakhs per day.
‡ Additional income could come from carbon credit trading. A 1 MW plant
by generating 8000 KWH x 300 sunny days = 24,00,000 KWH which if
traded for Rs 1 to another polluting steel or coal power generating
company could fetch Rs 24 lakhs per annum as surplus income.
‡ The Government of India not only offers to purchase the electricity
generated at a higher tariff but institutions like IREDA can fund up to
80% of the project cost.
‡ The plant has a virtually zero running cost as all it needs is sunlight. The
solar panels, inverters and trackers can be expected to last between 25-
35 years. Solar panel cleaning could be done either manually or with the
help of automated solar panel cleaners. Some investments for plant
security may be needed.

3. solution
1)Solar panel trackers are not manufactured in India and they are at the
moment being imported from China. Since we need a fairly large quantity of
solar panel trackers for this 1 MW plant and other MW scale solar plants we
wish to build in India a tracker manufacturing plant is needed. To create a
tracker manufacturing infrastructure here in India we need funds worth Rs 25
lakhs.
2) Combined solar thermal & PV development - Solar energy is converted into
electricity via 2 methods : photovoltaic's & thermal. In photovoltaic's certain
semiconductors when exposed to light produce an electric current. The
efficiency of solar photovoltaic (PV)systems range from 14% - 36%. In solar
thermal, the heat from the sun is used to heat large amounts of water which
is then used to drive turbines. Efficiency of solar thermal system is around
22%. We wish to combine solar thermal & PV systems to take efficiencies to
over 50%...Also, solar thermal power generation techniques are labor
intensive, so more important for India which is capital scarce and labour
surplus..This R&D development will need funds worth Rs 1 crore.
In India, no bank funds any R&D project and since mine is a small company,
despite various efforts we have been denied access to the funds.

4. IntroductionIntroduction
ͻ A Solar Power plant produces
electricity by reflecting
sunlight on to the central
receiver
ͻ A solar thermal plant consists
of mirror reflectors called
heliostats

5. ‡
Heliostats
ͻ They direct and concentrate the
solar radiation onto a central
receiver.
ͻ Many parameters must be
optimized, in the design of a
solar thermal plant
ͻ The parameters are
ʹ Location
ʹ Shading and
ʹ Blocking

6. ‡
Shading and Blocking
Shading occurs when a heliostat
casts its shadow on another
heliostat located behind it
ͻ Blocking occurs when a heliostat in
front of another heliostat, blocks
the reflected suns energy on its
way to the receiver

7. Components & its working
‡Parabolic tough shaped mirrors are the sunlight receivers,
they absorb the heat and is collected in special collectors.
‡This heat is transferred to the central receiver through
these collectors.
‡These parabolic receivers are in the particular angle ,which
reflect towards central receiver .

8. Continued..
‡Collectors contain panels which have
thermal transfer fluid which gets
heated. Almost till (400°c to 750°c ).
‡This liquid is pumped through a series
of heat exchangers to produce super
heated steam.
‡This stem is used to rotate turbines to
produce electricity.

11. Working of a turbine generator

12. Cost break up
The cost break up of the solar plant is as under -
Single sun solar cells of 1 MW or 1000 KW - Rs 12.50
crore
Double axis trackers costing approx - Rs 5.00
crore
Grid feed Inverters (MPPT) 250 Kw x 4 - Rs 2.00
crore
Special UV / IR Filter cover glass - Rs 3.75
crore - helps prevent solar cell heating ageing
Land around 10-15 acres - Rs 2.50
crore - Varies greatly
Plant site development erection - Rs 1.00
crore
Total : Rs 26.75 crore.
