Rohit-
Thanks for this compilation. I have gone though some of the products. 
The best part is these lamps do not need wiring.

However, I think it can help to decide if we all get to understand the below:
1. If there are any experts who can advice on what model is best for a garden area like ours. 
Are there people who can run this as a project (We may or may not need them)
2. What will be the overall cost for these lamps. What will be the cost of maintenance. 
E.g. How often to change the batteries. 
3. By when we can get to breakeven. We can get the cost of the existing garden lamps from Estate Manager.
4. Are there shops which sell accessories for these lamps in Bangalore

Overall, this looks exciting as it can bring in some aesthetic look and feel at optimum running cost...

Sanjeev / Randhir / Aparna -
Your ideas?

Thanks,
Jai

Subject: About Solar lighting in the garden at eco

Hey Jaiganesh

Pursuant to our discussion on solar lighting in the apt complex,
have gathered some links about the garden lights here:
http://alpine-eco.wikidot.com/solar 
Please see the products section and decide on which may be useful for eco.

Takeaways:
1. solar lighting provides lighting for about 8 hours.
2. in some models, the lighting dims as the night progresses 
3. a combination of solar + led lights provide the max value for money.

thanks

SPECIFICATION FOR SOLAR PHOTOVOLTAIC SYSTEM
(MNES 2005-2006 SPV PROGRAMME)
SOLAR LANTERN
1. Definition:
A Solar Photovoltaic Lantern is a lighting system consisting of a lamp,
battery and electronics all placed in a suitable housing, made of metal,
plastic or fiber glass and a PV module. The battery is charged by electricity
generated through the PV module. The lantern is basically a portable lighting
device suitable for indoor or outdoor lighting covering a full range of 360
degrees. A lighting device which provides only unidirectional lighting will
not be classified as a solar lantern in the present context.
2. Duty Cycle:
The solar lantern should provide a minimum of three hours of lighting per
day under average daily solar radiation conditions of 5 kWh/sq.m. on a
horizontal surface. The actual duration of lighting may vary depending on the
location, season, etc.
