No problem. Do you have a specific question, or do you want a general guide?

http://www.appropedia.org/Briceland_PV  will give you an overview. There are
also diagrams in http://www.backwoodssolar.com  and
http://www.newenglandsolar.com  catalogs that are very helpful.

We can also help you design a appropriate sized system before you start
ordering equipment as well, if you can give us a general location, and what
devices you need to power and for how often.

Many Thanks Mr. Steve Spence for the reply. Lemme give some details
about my system
I got one system installed in North-East Part of Bangalore. This
System is built by Emmeve Solar [http://www.emmveesolar.com/ ]
Its a water heating system with capacity 125Ltrs. Water is getting
heated but heat is not retaning till 24hrs. If I consult customer
care, they are saying that its due to shadow. It is hard to me to
understand how shadow is causing problem

thanks

Try sitting in the sun for one hour, and then try sitting in the
shaddow for one hour, and you will get the idea.:-)

Any shaddow will decrease the efficiency of solar collectors and PV.
If there are just a litle shaddow a short time of the day, you may not
notice it. But if there is a big tree or somethink like that, stopping
the sunbeams, you will get a lot less heat.
Also, the solar collector (black) will get cold faster than a white
object. Just as it is heated quicker.

============================================
Is the tank well insulated? How much hot water do you use from the
time the sun goes down till the next day? Hopefully not more than 1
liter or so...
