2. Why Solar For Home ?
Cost of electricity increasing every year by 15-20%
300 million people in India don’t have electricity access due to lack of
infrastructure Geographical condition
over 300 million Indian citizens had no access to frequent electricity
coal, India is facing a severe shortage of coal and conventional resource
going to end in coming years
Sun is non ending source of green clean & independent energy that can
be availed for very long time with minimum expense
3. Types of Solar System for
Home
Stand
Alone/Off Grid
Hybrid System
Grid
Interactive/Grid
Tie
4. Stand Alone/Off Grid SystemOff Grid/Stand Alone System
Illuminate your home where electricity can't reach
Become Independent of Rising Electricity price
This system most suitable for rural
and hilly area where Electricity
through Grid is not Possible. Off-
Grid System allows you to be self-
sufficient anywhere and at any time.
You produce your own environmentally friendly and inexpensive solar
power in your won power plant
5. Hybrid /Smart System
This kind of system most
uitable for Area with
non reliable and irregular
electricity supply
All available resource
ike solar ,Wind, Grid
lectricity can be
ntegrated in one system
A very cost effective system with small battery bank is possible
hrough such smart system
You can have more control on electricity consumptions
6. Grid Tie/Grid Interactive System
Grid Interactive system
specially designed for
urban area with reliable
electricity supply but
with high cost
You can reduce your
electricity bill Up to 90%
with such eco-friendly
system
Intelligent Control on your total electricity consumption.
7. 1KW Off Grid Solar System
Home with electricity consumption of 100-130 unit monthly can be
energies with 1 Kw solar system
For desire autonomy Battery bank may be selected
Considering 1 day autonomy a 24 V 250 Battery bank will be
most suitable.
Most places in India have 280-300 sunny days, one Day autonomy
will most suit woth cost effectiveness
8. 1.5 KW off Grid Solar System
Home with electricity consumption of 150-200 unit monthly can be
energies with 1.5 Kw solar system
Off Grid Solar inverter of 1.5 KW will be integrated and will be routed
through battery bank to Load/house hold appliances
Battery bank with 24 V 300 Ah will be sufficient to serve 24 hrs.
of autonomy
More then one day autonomy should be considerd for crital load and area
having less sunny days
9. Off Grid 2 KW Solar System
Big Houses with monthly consumption of 200-250 Unit of electricity
can opt an 2 KW stand alone solar system
A 48 V battery bank with 300 Ah value can be integrated with 2 KW
solar inverter
Electricity produced by this system is sufficient to run 5fan
10 LED light, 1 freeze for more and television in home
10. 3 KW stand alone solar system
A 3 Kw solar system is suitable big bungalow community center
and small school having consumption of 300-375 unit on monthly
basis
A battery bank of 400 Ah 48 V will be self sufficent for 3 Kw
system designed for 24 hour autonomy
Battery bank selection may be done in intelligent way to minimize
system cost without affecting the performance
11. Cost Effective Off Grid Solution
Battery bank selection play major role in designing cost effective
small solar plant as battery contributes 40% of system deep study
regarding load and its application time needed.
Loads operating in day time need smaller battery bank hence
school and community center operating in day time need
very small bank
By adjusting operating time of heavy load like Motor ,Washing
Machine we can minimize size of battery bank
12. Cost effective hybrid solution
Hybrid solar system can be designed in cost effective way
considering regularity in Grid electricity supply
Synchronizing Heavy load and using energy saving technique help to
reduce system cost and electricity bill
In areas where electricity supply is regular hybrid system is use
full in reducing bill of electricity
13. Grid Interactive system and pay back Period
Grid tie system no need any battery bank as contineous Grid supply is
necessary to operation
Pay back period of grid tie system in any region depending up on
traffic rate and solar resource in region
Considering electricity rate a Rs 9/unit fixed and irradiation 4.5
kw/m2/day pay back period is 5 yr. and life of the system is 25-40 yr.
